Most documentation goes stale the moment it's written. Slite fixes that: it's a knowledge base that keeps itself current, so engineers, ops and support teams (and the AI coding and chat assistants they rely on) always read accurate information. The built-in Slite Agent brings enterprise search to the tools where work actually happens, including GitHub PRs, Linear and Jira tickets, Slack threads and Google Drive. When something changes, it flags the docs that no longer match, proposes an edit as a side-by-side diff, and waits for a teammate to accept or dismiss it. Nothing is rewritten without human sign-off. Developers can plug Slite into Claude Code, Cursor or any MCP client, or script it through the public API. Both are available on every plan at no extra cost. Every change is logged with its origin: web, API, MCP or agent. Security: SOC 2 Type II, GDPR, EU data residency, plus SAML SSO and SCIM on Enterprise.

Your doc can add building blocks such as buttons and packs to do useful things, such as email your timesheet or nudge your colleague on Slack. The building blocks are arranged so that it feels like a native app when you open it on your phone. You can swipe to activate buttons. Sections are your nav. Notifications are sent to your phone.
