Granite is a secure Markdown note-taking and knowledge management application designed for both individuals and teams. It efficiently organizes notes through various features such as wikilinks, tags, backlinks, a visual graph, daily notes, templates, and an offline search capability, ensuring seamless synchronization across web, desktop, and mobile platforms. Each vault within the app is protected by its unique encryption key. The integrated MCP server allows AI tools like Claude, ChatGPT, and Cursor to access, read, and modify notes in authorized vaults while providing sourced answers. Collaborative features enable teams to co-edit shared vaults, leave comments and mentions, and publish notes online. For businesses, additional features include Single Sign-On (SSO), SCIM, audit logs, and enhanced security policies. Importantly, user notes are never utilized for AI training purposes. Granite provides a free plan for a single vault, along with a Pro subscription and Business plans that are billed per seat, making it accessible for a range of users. This comprehensive approach ensures that both personal and team knowledge management needs are met effectively.
