TheSecureNote

Granite is an encrypted Markdown note-taking and knowledge management app for individuals and teams. It organizes notes with wikilinks, tags, backlinks, a graph view, daily notes, templates, and offline search, and syncs them across web, desktop, and mobile devices. Each vault has its own encryption key. The built-in MCP server lets Claude, ChatGPT, Cursor, and other compatible AI tools search, read, and update notes in authorized vaults, with answers that cite the source notes. Teams can co-edit shared vaults, add comments and mentions, and publish notes to the web. Business adds SSO, SCIM, audit logs, and security policies. Notes are never used to train AI. Granite offers a free one-vault plan, a Pro subscription, and per-seat Business plans.
