Unlock Your Second Brain
Markdown notes that stay yours, in your OneDrive or Google Drive. Semantic search, AI chat and agents on the desktop, access from anywhere on the web.
Why InsightDown?
Live-view editor
Write Markdown and see the result as you type: edit tables right in their cells, code blocks are coloured by language, and links and attachments open with a click. Your notes are your files, with no limits.
Search and graph
A search panel with folder and tag filters and bulk replace. Search by meaning runs offline on the desktop with a local model and sends nothing out. The graph shows how your notes connect.
AI chat on the desktop
Ask a note, a selection or the whole vault. Free with your own key (OpenAI, Anthropic, Gemini or a local Ollama); in Pro also on our models, paid by usage.
AI agents (Pro)
Research with web search, vault cleanup and writing into your notes. You see every change first, approve it and can undo it any time.
MCP for AI assistants (Pro)
Connect Claude, ChatGPT or another assistant to your vault over MCP: locally from the desktop, or remotely from anywhere.
OneDrive and Google Drive
Your notes live in your OneDrive or Google Drive, or in a local folder on the desktop. Work on the desktop and the web; mobile apps are on the way.
Privacy and encryption
Encrypted notes, blocks and folders. We do not store the text of notes from cloud vaults on our server. The index for remote MCP is yours to turn on and delete any time.
Sharing and comments (Pro)
Share notes and folders by link or publish a whole vault. Others comment on them, even without an account.
The web as a companion
From any browser: the editor, attachments, sharing and comments, and your account. AI and offline work stay in the desktop app.
