AI Text-to-Speech Playback
Read app content and AI answers aloud, with a voice and speed the user controls.
What it adds
A playback control that speaks selected content aloud with voice, speed, seek, and stop controls.
What your agent is told to do

What your agent is told to do
5-
1
Pick the content genuinely worth hearing — long answers, articles, briefs — and put the playback control beside the text rather than in place of it.
-
2
Generate long content as ordered segments and queue the next one while the current is playing, so playback is continuous and a pause and resume returns to the same position instead of restarting a segment.
-
3
Authorize the text before synthesizing it, using the same permission check that governs reading the record. Otherwise playback becomes a route to hear content the account cannot open.
-
4
Cache generated audio against the text and the voice settings that produced it, and invalidate that cache when the text changes. Regenerating identical audio on every replay is a bill with no benefit.

Do not treat this as the app's accessibility story. Screen reader users need correct semantics and readable markup; spoken playback is a convenience layered on top of that, not a replacement for it.
Edge cases it handles

Edge cases it handles
8- Segment boundaries are where playback goes wrong. A gap between segments, or a sentence repeated because a segment restarted, is immediately obvious to a listener.
- Changing the underlying content, navigating away, or editing the text mid-playback must stop the audio at once and discard the queued segments, not carry on reading the previous version.
- Only text the current user is permitted to read may be sent for synthesis, and a cached audio file must not be servable to another account by guessing its address.
- Written text, transcripts, and controls must remain on screen. Content that exists only as audio is unreachable for anyone who cannot or does not want to listen.
- Provider failure, an unsupported language, and a voice that has been withdrawn are three different problems. Fall back to another available voice where sensible, and otherwise leave the text readable with the control disabled and explained.
- Mobile browsers block audio that starts without a user gesture, and playback stops when the tab is backgrounded on some platforms. Start only from an explicit action and restore position when the user returns.
- Cap the amount of text synthesized in one request and per account per period, because a listener who starts playback on a very long document can otherwise run up cost in a single click.
- Code blocks, tables, URLs, and markup read aloud badly. Strip or summarize them before synthesis rather than spelling out punctuation.
Definition of done

Definition of done
9- Playback of long content is continuous, with no gap or repeated passage at segment boundaries.
- Pause, resume, seek, speed, and voice selection all work and the position survives a pause.
- Changing or leaving the content stops playback immediately and clears the queue.
- Synthesis and cached audio are both restricted to text the requesting user may read.
- Repeated playback of unchanged text serves cached audio rather than generating again.
- A provider outage, unsupported language, or removed voice leaves the written content fully usable with a clear explanation.
- Per-request and per-account synthesis limits are enforced.
- The feature matches the existing design system.
- No existing functionality is broken.

AI Image Alt Text
AI Image Alt Text
Draft alternative text for uploaded images so screen readers get something useful.
What it does
A suggested alt attribute offered at upload time, editable and confirmable before the image is used.
How it works
- 1 Find every place the app accepts an image and currently stores an empty or absent alt attribute, and offer a suggestion at that point rather than in a separate cleanup screen.
- 2 Ask first whether the image is decorative. A decorative image takes empty alt text, and forcing a description onto it makes the page worse for the people the feature is meant to serve.
- 3 Pass the surrounding context — the page heading, the nearby caption, the purpose of the field — so the suggestion describes the image's role, not just its contents. Do not repeat an existing caption verbatim; a screen reader user would then hear the same sentence twice.

AI FAQ Generator
AI FAQ Generator
Produce short question and answer pairs from a document you have already approved.
What it does
A set of concise question-and-answer pairs generated from one nominated source document, each traceable back to the passage it came from.
How it works
- 1 Require the user to nominate a single approved source — a help article, a product page, a policy document — and generate only from that. Do not blend several documents or fall back to general knowledge when the source is thin.
- 2 Store each generated pair with a reference to the passage in the source that supports it, so a reviewer can confirm the answer without rereading the whole document.
- 3 Keep answers to a few sentences and link to the fuller section of the source for anything longer. An FAQ that restates the entire document is just a worse copy of it.

AI Translation
AI Translation
Translate app content while preserving structure, placeholders, and product terminology.
What it does
A translation pipeline over the app's translatable content that keeps source and target linked, protects non-translatable tokens, and routes uncertain output to review.
How it works
- 1 Identify what is genuinely translatable and separate it from what is not. Extract placeholders, markup, URLs, identifiers, code, and proper names into protected tokens before generation and restore them afterwards.
- 2 Store every translation with a reference to the exact source version it came from. When the source changes, mark the translation stale and queue it for retranslation rather than leaving a silently outdated string in place.
- 3 Hold a per-language glossary of product terms and their approved renderings, and apply it to every request. A term that translates three ways across the app is worse than leaving it in the source language.

It inspects, then implements
Your agent reads your existing app first, then adds the feature to fit it.
Works with your stack
These instructions are written to adapt. They tell the agent to detect your framework, match your existing design system, and reuse what you already have — rather than assuming a particular stack.
