Granite - Second AI Brain

Granite turns your notes into a second brain your AI can use. Write in Markdown, keep everything encrypted and synced on all your devices, and let the AI assistant you already use search, read and update your knowledge base, only with your permission. YOUR KNOWLEDGE BASE, READY FOR AI • Connect any AI assistant that supports MCP (Model Context Protocol) to your notes with Granite Pro. The server address is in Settings > AI tools • Your AI can search your vaults, read notes with their tags, links and backlinks, and create or update notes for you • Search results point back to the exact note and heading they came from, so answers are easy to check • Add Google Drive files to notes by link, and they become context for your AI too • See every connected app in Settings and disconnect it at any time, it loses access at once • Granite doesn't run its own AI model, and your notes are never used to train AI SECURE BY DESIGN • Encrypted in transit and at rest, with a separate key for every vault • Optional app lock with Face ID, Touch ID or fingerprint • Two-factor authentication and a list of your signed-in devices • No ads and no tracking. Export your data or delete your account from Settings at any time SYNCED ON EVERY DEVICE • One account on your phone, tablet, computer and the web • Notes are stored on your device first, work offline and sync in the background • Fast full-text search on your device, even without a connection: exact phrases, excluded words, tag: and path: • Version history: compare and restore earlier versions WRITE AND CONNECT IDEAS • A Markdown editor with a formatting toolbar, so you never have to remember syntax • [[Wikilinks]], #tags, math and photos from your library • Backlinks, a graph of each note's connections, outline and related notes • A daily note in the Today tab, templates and canvas boards • Quick capture from the app icon, and on Android, "Save to Granite" from any app's share menu WORK TOGETHER • Live co-editing: see who else is in a note and where they're typing • Comments with replies and @mentions • Share a note or a whole vault with the people you choose • Publish a note as a web page, with an optional password FOR TEAMS If your company uses Granite, sign in with your work email, including single sign-on.
