It’s free to use and supported via email and GitHub Issues, making it an ideal choice for startups and expanding organizations.
Slite is a team knowledge base and documentation platform built to keep company information accurate over time rather than going stale in a wiki nobody updates. It combines AI-powered search across connected tools with a doc verification workflow, so team members can confirm or flag content as still correct, and Slite can detect when connected source data has drifted from what's written. Beyond internal docs, Slite's AI search can pull answers from 20+ connected tools including Slack, Linear, GitHub, Jira, and Salesforce, and its Agent can automate workflows like drafting or updating docs based on triggers. It's used by 1,700+ companies, many migrating from Notion, Confluence, ClickUp, or Quip.
