What it does
Granite stores personal and team notes as plain Markdown, with encrypted vaults, full-text search, backlinks, version history, and live co-editing. Its company knowledge base can be searched by connected AI tools through a permission-filtered MCP server. The Free plan includes one synced vault and 50 MB; Pro is $3.99 per month and Business is $14.99 per seat per month, billed monthly.
Granite combines personal note-taking with a shared company brain rather than treating them as separate products. Plain Markdown, per-vault encryption, version history, backlinks, and live co-editing give individuals and teams one place for durable notes. For companies, its MCP server can return knowledge with permissions filtered to the person asking. The free tier is deliberately small at one synced vault and 50 MB; paid plans add capacity and company controls. Teams should check their data-security and AI-access requirements before connecting workplace notes to external assistants.
Strengths
- Notes remain in plain Markdown and are protected with per-vault encryption.
- The company knowledge base supports live co-editing and permission-filtered AI search.
Watch out for
- The free tier is limited to one synced vault and 50 MB.
- Business features are priced per seat, so a team should compare the recurring cost with its existing knowledge tools.
Best for
- People who want a private Markdown second brain with sync and backlinks
- Teams that need searchable, permission-aware company knowledge alongside personal notes
