Inbox Triage Extension
Inbox Triage is a Chrome extension that summarises email threads, analyses attachments, and generates reply drafts — all using on-device AI so nothing leaves your machine.
How it works
Content scripts extract email data from Gmail and Outlook. A service worker coordinates the AI processing, and a side panel provides the interface. It uses Chrome's built-in AI APIs (Summarizer, Prompt, Translator) for local processing, with optional cloud model support if you prefer.
Key features
- Thread summaries — automatic summarisation with key point extraction for any email thread
- Reply drafts — three tailored drafts per email in multiple tones and styles, injected directly into Gmail/Outlook compose windows
- Attachment analysis — image analysis with OCR via a single button
- Voice input — customise draft guidance using voice-based input
- Multilingual — local translation across 15+ languages via Chrome Translator API
- Works offline — fully functional once the on-device models are downloaded
- Session restore — previous summaries persist across browser sessions
Privacy first
Everything runs through Chrome's built-in AI APIs by default. Your emails never leave the browser. If you want cloud-based models, you can optionally configure API keys for OpenAI, Anthropic, or Google Gemini — but it's entirely opt-in.
