When to use

• Messages, comments, reviews or support tickets written in another language, translated on demand inside the product.
• Release notes or announcements that readers in several regions open in their own language.
• Any place you want an AI translation to feel inline and reversible, with the original one click away.

When not to use

• Translating a whole page or app interface; use your i18n framework.
• Long documents with headings and lists; this renders one plain paragraph.
• Live captions or speech; use a realtime stream component.

API reference

AiTranslate

An inline translator for one message or paragraph. A byline with a detected language chip sits above the text; below it, a Translate picker (English, Deutsch, Français, Español, 日本語, Português), a Show original toggle and a status line credited to the model's mark. Picking a language dims the text on screen and streams the translation in place in fast chunks, each new sentence retiring one sentence of the old text, while the card's height springs to fit. Finished translations are cached, so Show original and switching back crossfade instantly. Failures put the previous text back and show Couldn't translate with Retry.

Prop	Type	Default	Description
text	string	sample release note in French	The text to translate, in its original language. Changing it clears cached translations and shows the new original.
sourceLanguage	"en" | "de" | "fr" | "es" | "ja" | "pt"	–	Language of text. When omitted it is detected from the text with a light stopword check and the chip reads Detected; when passed the chip reads Written in.
languages	AiTranslateLanguageCode[]	all six	Languages offered in the picker, in order. The source language appears as Original.
value	AiTranslateLanguageCode	–	The language on screen; the source language means the original. Pair with onValueChange to control it, for example to remember a reader's preferred language.
defaultValue	AiTranslateLanguageCode	sourceLanguage	Starting language when uncontrolled. A language other than the source translates on mount.
onValueChange	(language: AiTranslateLanguageCode) => void	–	Called when the reader picks a language or toggles Show original.
translate	(request: { text, from, to, signal: AbortSignal }) => Promise<string> | AsyncIterable<string>	–	Your translation call. Resolve the whole translation, or return an async iterable that yields text deltas as your model streams them. The signal aborts when the reader picks another language, shows the original or the card unmounts. A thrown Error's message is announced and kept as the error tooltip. Without it, translations are streamed as a simulation.
translations	Partial<Record<AiTranslateLanguageCode, string>>	–	Ready translations, streamed by the simulation. Useful for content you translated ahead of time; a missing language shows the error state.
onTranslate	(result: { from, to, text }) => void	–	Called once a translation has fully arrived, before it is cached.
onError	(error: Error, request: { from, to }) => void	–	Called when a translation fails. Aborted requests never call it.
author	{ name: string; role?: string; avatar?: string } | null	sample author	Who wrote the text, shown with an avatar. Pass null to hide the byline; the language chip stays.
timestamp	string	–	Shown after the role in the byline, for example "Oct 27, 09:14".
model	{ name: string; mark?: ReactNode }	{ name: "Claude Haiku 5.5", mark: Claude mark }	The model credited in the status line. The mark leads every status; the name is the idle label.
autoPlay	boolean	true for the bare sample	Tours English, Deutsch, 日本語 and Português, then the original, and loops. Pauses off screen and stops for good on the first pointer or key press inside the card. With reduced motion it translates once and stops.
simulated	boolean	true without translate	Adds "Simulated, nothing was sent" to the live status.
className	string	–	Class on the root section.

Keyboard interactions

Keys	Action
Tab	Moves through the Translate picker, the Show original toggle and, after a failure, Retry.
Enter / Space / Arrow down	On the picker, opens the language menu with the current language checked.
Arrow keys, Home, End	Move through the languages; typing a letter jumps to a language. The list loops.
Enter / Space	Picks the highlighted language and closes the menu. Picking the language that just failed retries it.
Escape	Closes the menu with focus back on the picker.

Accessibility

• The card is a section named after the author. The paragraph carries the lang attribute of the language on screen, and dimmed old sentences keep their own lang, so screen readers pronounce both correctly.
• Start, completion, the original and failures are announced in a polite status region; the paragraph is aria-busy while it streams. The simulation says that nothing was sent.
• The language menu is a radio group with a checkmark on the current language. The Show original toggle is a pressed button whose label switches to Show translation.
• Status is never color alone: the model mark plus a label (Translating to German, Translated from French, Showing original), or a warning icon plus Couldn't translate.
• Every control is at least 32px tall, and labels reserve the width of their longest version, so nothing moves under the pointer.

Motion

• Streaming: chunks of 3 to 6 words (about 10 characters in Japanese) land every 34ms and only fade in over 140ms. No blur, slide or per word spring.
• The text on screen dims to 45% over 200ms as translating starts, and each sentence that starts in the new language removes one dimmed sentence, so the translation replaces the paragraph sentence by sentence.
• Cached translations and the original swap with one crossfade: the old text leaves in 100ms, the new one fades in over 160ms with a 2px rise.
• The paragraph's height follows its text with a critically damped spring (visualDuration 0.24, no bounce); window resizes cut straight to the new height.
• Status labels crossfade in one shared cell; the picker and toggle labels crossfade inside their reserved width. The menu fades and scales from 98% in 150ms.
• Reduced motion keeps every end state and announcement but drops chunk fades, crossfades and the height spring, and autoplay runs once.

Responsive behavior

• The card fills its container up to 620px and pads 16px on phones.
• Below a 470px card width the status line drops under the controls, left-aligned with the text; below 380px the chip shows just the language name.
• Names and meta truncate with an ellipsis; the paragraph wraps with text-wrap: pretty. No horizontal scroll at 360px.

Performance

• Chunks append as spans with a CSS fade, so streaming re-renders one paragraph and never animates layout.
• One ResizeObserver drives the height spring; autoplay pauses through an IntersectionObserver while the card is off screen.
• Every request owns an AbortController; switching language or unmounting cancels the network call and timers.

Notes for AI

• Wire translate to your model. Return an async generator of deltas to stream real tokens, or a Promise<string> and the component streams it in chunks itself. Always pass the signal to fetch.
• Cache lives per instance and per text; a new text prop clears it. Persist translations yourself (onTranslate) if you want them across sessions, then pass them back in translations.
• Use the source language as value to show the original. Show original remembers the last translated language for Show translation.
• Keep one paragraph or message per instance. For a whole thread, render one AiTranslate per message and control value from a shared preferred language.
• Model names in samples must be current: Claude Haiku 5.5 is the default credit; swap the mark and name for your provider.
• Sentence splitting keeps decimals like 4.2 whole and handles 。！？ for Japanese.

Related

• Chat thread: A chat thread with grouped messages, reactions, read receipts, typing, and a composer with attachments.
• Text shimmer: Show ongoing work with a calm light across the words.
• Dropdown menu: A focused list of actions anchored to a trigger.
• Response feedback: A feedback control for AI replies where thumbs down opens an inline panel with reason chips and an optional note, thumbs up fills and asks what was good, and a submit shows a short thank-you before folding back into the row.
• Meeting summary: An AI meeting notes card: the header shows the Google Meet or Zoom mark, the attendees and the duration. Summary, Decisions and Action items stream in after a short summarizing pass. Hover any line to see the transcript quote it came from, then check off action items or send them to Linear or Notion.

Also in ai

• Agent status: A compact live status pill for a running AI agent: the agent's mark in a live ring, the current activity and an elapsed timer, opening into the steps so far.
• Tool call: A tool call row for agent transcripts: the tool's mark and the call in plain words, a live state while it runs, and the input and output a click away, with approval and retry when needed.
• Agent plan: The plan an agent writes before it acts: edit, reorder or add steps while it is a draft, then watch it work through them as a live checklist.
• Agent timeline: A compact timeline of one orchestrated agent run: the orchestrator and its subagents share a time axis, handoffs draw in between rows, and a playhead replays thinking, tool calls and waiting while the header counts time, tokens and cost. Hover a span for what it did, or click it to trace its handoff path.
• Context window: An AI context window as a grid of 200 cells: the system prompt, tools, files, summary and messages fill it in order, a threshold row marks where compaction starts, and sending a message, attaching a file or compacting shows exactly how much still fits.
• Reasoning block: The collapsible thinking block of an AI reply. While the model thinks, a shimmering label counts the seconds and the latest reasoning streams underneath. When it finishes, it folds to "Thought for 7s" and opens to show the full reasoning as calm steps with headings.
• Source cards: A row of cited sources under an AI answer where cards stream in with real site marks while the model searches, the overflow collapses into a stack of favicons, hovering lifts a preview with the passage, and an inline [n] citation highlights its card.
• Model card: A model details card where switching models rolls every price, limit and score in place, a token slider estimates monthly cost live, and benchmark bars show each model's rank on hover. Compare crossfades to a side-by-side table against any rival with the better values marked, and the card never changes size.
• AI workflow: A Linear-style AI workflow card where a Gmail trigger, a Claude step, a branch and Slack and Linear actions sit on one hairline rail, and a test run glides down it, opening each step's output inline. Steps are added from a compact command menu with real app marks.
• Code suggestion: An AI code edit suggestion where the model's proposed changes stream into a small editor panel as inline diff hunks, and you accept or reject each one, or all at once with Cmd+Enter. Accepted hunks fold into the file with a smooth height change.
• Ghost text: An inline AI autocomplete where muted ghost text continues your sentence exactly at the caret and Tab turns it solid in place. Cmd+Right takes it one word at a time, Escape fades it away, and a calm chip shows the model behind it.
• Image generation: An image generation card where four images resolve as a pixel mosaic, from coarse colour blocks to full detail under a soft shimmer, each with its own progress ring. Pick one to upscale with a sweeping pixel band, vary or download it, with real provider marks and a built-in simulation.
• Dictation button: A chat composer with voice input, where the mic springs into a recording pill with a smooth live waveform, a timer, and cancel and insert buttons. Words stream into the field as you speak, muted until the recognizer settles them.
• Speech player: A read-aloud player for AI replies. The Read aloud button in the message's action row turns into a compact player with play, a scrubbable progress bar, speed and a voice picker, and a highlight follows the spoken word through the reply, karaoke style.
• Reply draft: An AI email reply drafter where Claude streams a reply under a received Gmail message. Quick replies steer a fresh draft, tone and length rewrite it with a single crossfade, and you can edit the finished draft before you insert it.
• Agent handoff: A support conversation where an AI assistant hands off to a person. When it transfers, a card shows the summary it passes to the team and the typical wait. The person then joins and takes over, and a thin timeline on the left marks each step.
• PII redaction: A guardrail card where personal data is redacted before the prompt reaches the model. Scan marks each name, email, phone number and card with its type and swaps it for a placeholder like [EMAIL_1]. The safe prompt travels to Claude, and the reply comes back with the original values put back for the person.
• LLM cost calculator: A pricing calculator for LLM workloads. Set tokens per request, requests per day and prompt caching, and eight current models re-rank by monthly cost. Bars glide and prices roll as you drag.
• Provider keys: A settings card for bring-your-own-key AI products. Each provider row shows its real mark, the masked key, a status and when the key was last used. You can reveal a key for five seconds, copy, rotate or remove it with undo. Adding or rotating a key opens an inline form that checks the format as you type, then tests the connection before saving.
• Generation stats: A live stats strip for a streaming LLM response where time to first token, speed with a sparkline, output tokens and cost count up in tabular numerals beside the model's real mark, then settle and open into a latency and token cost breakdown.
• TL;DR toggle: An article card with a Full, Summary and Key points switch and a length slider. Switching streams an AI summary in place of the article as the card's height springs to fit, and each key point links back to the paragraph it came from, which gets scrolled to and highlighted.
• Connector setup: A "Connect your tools" card for an AI assistant. Each app connects inline: it redirects, authorizes and runs a first sync with a progress hairline, then lists the scopes it was granted and offers Disconnect with an inline confirm.
• Smart form fill: A paste-to-fill form card where AI reads an email signature or messy notes and fills a contact field by field. Each value flashes in with a confidence dot, its source lights up in the pasted text, low-confidence guesses ask for review, and Undo puts the old values back.
• Enrich column: An AI enrichment column for a data table, where one prompt runs down every row and each cell shimmers while it works, then settles into a value with its source or a failure you can retry.
• Ticket router: A support ticket router where messages from Gmail, Intercom, Slack and Zendesk come in one at a time. An AI classifier labels each one with intent, sentiment and confidence, and the ticket moves into a team lane with an assignee. Low confidence tickets wait in a review lane, and one click there routes them to the suggested team.
• Ask your data: A natural language to chart card: you ask a question, PostgreSQL streams into a collapsible, syntax highlighted panel, the query runs with a rolling row count, and the answer builds as stacked bars, lines or a table, with a one line insight streamed in underneath.
• Agent cursor: A live document where Claude edits like a collaborator. Its labeled cursor comes out of its avatar, selects a paragraph and streams in a rewrite, adds a heading and fixes a typo, while a teammate's cursor reads along. Changes stay tinted until someone accepts or undoes them from a floating review bar.
• Provider status: A status card for the AI providers your product depends on. Each row shows the provider's real mark, its health as an icon and label, p50 latency and a 30-day uptime bar with a tooltip for each day. An incident row expands into its timeline of updates, and the card checks again on a visible countdown.
• Training run: A fine-tuning job card where a live train and validation loss curve draws across a fixed step axis that doubles as the epoch progress bar. It shows the learning rate, elapsed time, ETA and the latest evals and checkpoints, has Pause and Cancel while it runs, and ends in results with a Deploy button.
• AI command: A Cmd+K command palette with an AI mode. Search pages and actions, or press Tab to ask a question: the answer streams inside the palette with numbered sources, and the next steps it suggests, like filing a Linear issue or opening a Notion doc, run straight from the list.
• Starter prompts: A greeting and a grid of starter cards for the empty state of an AI app. The cards are grouped into Write, Code, Analyze and Plan tabs, and a shuffle swaps them with a short staggered crossfade. Picking a card fills the composer, and cards that use a connected app show its mark (Gmail, GitHub, Notion, Linear, Google Calendar).
• AI mascot: A small assistant character, a soft pebble with pill eyes and a companion dot, that shows what the AI is doing. It breathes and glances when idle, leans in to listen, looks up while the dot orbits its head, reads along the line it writes, squints with a sparkle when done and shakes once with worried brows on an error.
• Image reveal: An image generation canvas where a soft, blurred preview made from the image's own colors sharpens top to bottom behind a soft-edged band. It works the way ChatGPT, Midjourney and Gemini show images forming, with fine film grain, a translucent progress pill and calm queued and error states.
• AI spark: A brand-quality animated spark mark. Four tapered rays and four lighter diagonals breathe at rest, ripple while thinking, pulse like a heartbeat while writing, then gather and settle when done. Every status change blends from the pose the mark is already in.
• Pixel mascot: A pixel-art robot that shows what an AI assistant is doing. It idles, thinks, types, celebrates and errors in frame-stepped sprite animations, and stays crisp at every integer size from 24px to 192px.
• Ghost mascot: A floating ghost mascot whose soft sheet ripples at the hem while it hovers. It blinks when idle, turns toward you to listen, fades a little translucent while thinking, draws a tiny pen line while writing, smiles with a sparkle when done and wobbles once on an error.
• Cube mascot: An isometric cube mascot where three shaded faces and a painted-on face show what the assistant is doing. It turns a quarter turn in eased steps while thinking, prints lines onto the floor while writing, settles with a sparkle when done, and shakes once on error.
• Tone tuner: A brand voice card where two sliders (formality and detail) and Friendly, Confident and Empathetic chips rewrite a customer reply. Each changed sentence crossfades in place, new words can be highlighted against the original, and Copy takes the current version.
• Upgrade prompt: An upgrade nudge for the moment someone hits a limit. It shows a usage meter at 50 of 50 AI credits, a rolling price with a monthly and yearly toggle, three concrete unlocks with real model marks, and Upgrade or Maybe later. Upgrading leads into a success state with the new limits, and the card never changes size between states.
• Referral card: A give-and-get referral card where people copy or share their invite link, invite friends by email as chips, and watch invites move from invited to signed up to earned, with the credit total counting up and a milestone reward unlocking.
• Trial banner: A trial status banner where a ring counts down the days left, the copy names what the workspace loses, and the upgrade path is one click away. It comes as a slim banner, a sidebar card or a header pill. It shifts to a warning tone in the last days, has expired and upgraded states, and folds into the pill when dismissed or snoozed.
• Team switcher: A workspace switcher like Linear, Vercel or Slack. The trigger shows the current workspace's logo and plan. The menu has search, your role in each workspace and a Cmd+1 to 9 shortcut for each, and lets you create or join a workspace inline. A highlight glides between rows, and switching crossfades the trigger through a short loading state.
• Live visitors: A realtime visitors card where the live count rolls digit by digit, new arrivals ping in on a dotted world map, the top pages reorder with bars, and signups and upgrades tick in with country flags.
• Social proof toast: A stack of social proof notifications for landing and pricing pages, where recent trials, upgrades and verified purchases from people and companies arrive every few seconds. The stack pauses and fans out on hover, and visitors can dismiss any toast.
• Install snippet: A "get started in 30 seconds" card where framework tabs, three numbered steps and highlighted snippets take a developer from install to first event. Generate key wipes a fresh API key into the placeholder in place.

Guidance for AI tools

AI translate: A message card where picking a language streams the AI translation in place, sentence by sentence over the dimmed original, with a detected-language chip, a Show original toggle and a status line credited to the model's mark. Follow the declared prop types and do not invent props. Keep keyboard access, reduced motion support, and both light and dark themes intact when adapting it.
