Intelligent AI-Powered Keyboard Assistant for Android
TypeAssist is a powerful Android Accessibility Service that acts as an intelligent layer over your existing keyboard. It integrates cutting-edge AI (Google Gemini, Cloudflare Workers AI) and a suite of offline utility tools directly into any text input field on your device.
No more switching apps to fix grammar, translate text, or calculate math. TypeAssist is always just a trigger away.
- Ask AI: Query Google Gemini or Cloudflare Workers AI directly from any app.
- Grammar Fix: Instantly correct spelling, punctuation, and grammar errors.
- Translation: Translate text from any language to English (or your preferred language).
- Tone Adjustment: Rewrite messages to be more professional, polite, or friendly.
- Inline Commands: Embed AI queries within sentences using
(.ta: your prompt).
- Smart Calculator: Solve math expressions in-place.
- Example:
(.c: 25 * 4 + 10)->110
- Example:
- Snippets (Text Expander): Expand shortcuts into full text blocks.
- Example:
..email->user@example.com
- Example:
- Date & Time: Insert current timestamps with
.nowor.date. - Password Generator: Generate strong random passwords on the fly with
.pass.
- Global Undo: Revert any action instantly using
.undo. - History Manager: View and recover original text from the last 2 minutes.
- Privacy First: Processes text only when a trigger is detected. No data is stored permanently.
Type your text followed by a trigger to process it.

TypeAssist uses an Accessibility Service to function.
- It does not log your keystrokes.
- It does not send data to any server unless you explicitly use an AI trigger (
.ta,.g, etc.). - It is fully Open Source, so you can audit the code yourself for peace of mind.
