Everything your team writes and says, indexed and cited.
Leon syncs your tools and AI assistants, stores every item verbatim, keeps AI conversations private to their author, and answers with sentence-level citations.
Connects to your tools and AI assistants.
42 connectors over OAuth or an API key, synced incrementally every 15 minutes. AI conversations arrive through the browser extension and a coding-assistant hook.
- Polls each tool every 15 minutes; nothing to set up on the vendor side
- Extension: explicit consent, per-site toggle, paused in private windows
- Coding assistant: each session captured when it ends
Stores the originals, with access rules attached.
Leon stores each item verbatim, with a link to the original. Recognizable secrets are redacted before anything is stored.
- Every result opens in its source tool
- AI conversations, chats and notes private to their author
- API keys, tokens and .env secrets redacted before storage
Hybrid search across every source, with the answer on top.
Postgres full-text and vector search run side by side and are merged with reciprocal rank fusion, always after the permission filter. A generated answer sits above the results, every sentence cited.
- Inline filters: from:, tool:, type:, since:, before:
- Exact-phrase matching in quotes
- Typo-tolerant title matching
from:julie- written by one person
tool:github- one connector only
type:meeting- ticket, page, email, meeting, conversation…
since:7d- last 7 days; also weeks or months
before:2026-10-01- before a date
"exact phrase"- exact match
Chat that cites its sources, or says it doesn’t know.
Leon searches, reads and cross-checks sources before it answers. Every claim is cited. When the sources fall short, it says so instead of guessing.
- Private chats you can delete
- Morning briefing: done, changed, still open
- Available to any MCP client
