Dexi

Dexi is a personal knowledge base that captures everything in one place — typed notes, web bookmarks, emailed articles, and RSS feeds all become searchable notes. Connect it to Claude and your accumulated knowledge becomes part of every conversation.

What Claude can do with Dexi connected:

• Search your notes by keyword (full-text) or by meaning (semantic search over vector embeddings) — "what have I saved about pricing experiments?" finds relevant notes even when the words don't match.
• Read any note in full, list and filter by tag, folder, or source kind (bookmark, email, feed article, typed note), and surface semantically similar notes to whatever you're discussing.
• Capture as you go: create notes from conversations, append research findings to existing notes, and organize with #hashtags and @mentions that become tags automatically.
• Run your spaced-repetition review: Dexi tracks flashcard-style review schedules (SM-2) for notes you choose to memorize, and Claude can quiz you on due cards and record how well you recalled each one.

Every tool operates on your own account through OAuth — Claude sees exactly what you can see, nothing more. At connection time you can optionally restrict access to a single folder and/or tag, and you can revoke the connection at any time from Dexi's settings. Read and write tools are separate, and destructive actions (like deleting a note) are annotated so Claude asks before using them.

Dexi has a free plan with 1,000 notes. Sign up at app.dexi.net, save a few things via the web clipper, email, or the editor, and connecting Claude takes under a minute.
