Semantic Search for Telegram Web

About

Semantic Search for Telegram Web turns your Telegram Web history into a searchable, AI-assisted personal knowledge base — entirely on your own device.

Find messages by meaning, not just keywords
Search across everything you've browsed on Telegram Web using natural language. Three levels of search intelligence keep it fast on any device:
• Level 1 — instant keyword search, always available
• Level 2 — semantic reranking of top results using on-device AI
• Level 3 — full semantic search across your entire index

Live, incremental indexing
No setup required. Messages are indexed automatically as you browse Telegram Web. For deeper history, you can optionally import a full Telegram Desktop export.

Organize with Workspaces
Group messages, files, and links into topic-based workspaces, with similarity-based suggestions to help you build a personal knowledge base over time.

AI Summaries
Generate summaries and action items for any chat or workspace — fully on-device by default, or via your own Anthropic API key for higher-quality cloud summaries.

Privacy-first, local by default
• All messages, indexes, and workspaces are stored only in your browser — there is no backend server, and we cannot see your data.
• Older data is automatically compressed and encrypted on-device; the encryption key never leaves your device.
• No Telegram credentials or session tokens are ever accessed.
• Two optional features — cloud AI summarization and Google sign-in — are strictly opt-in and off by default. Google sign-in only shares your name/email/photo and is used to unlock Level 2/3 search and AI summaries; no message data is ever sent to Google.
