Slite

Slite takes a focused approach to team knowledge management that resonates with agencies drowning in scattered documentation. Instead of trying to be everything like Notion or Confluence, Slite concentrates on making it dead simple to write, organize, and — most importantly — find information when you need it. The AI-powered search doesn't just match keywords; it reads your entire knowledge base and answers questions in plain language, which eliminates the 'I know we documented this somewhere' problem.

For agencies specifically, Slite solves the institutional knowledge challenge that grows with every new hire. SOPs for client onboarding, design system guidelines, development standards, pitch templates, and meeting notes all live in organized collections that new team members can navigate intuitively. The verification system prompts content owners to review their docs periodically, which prevents the knowledge base rot that plagues most team wikis. When someone asks 'What's our process for client offboarding?' the AI can surface the answer instantly, even if the document isn't titled that way.

Compared to Notion, Slite is less powerful as an all-in-one workspace but significantly easier to adopt as a pure knowledge base. Compared to Confluence, Slite offers a cleaner, faster experience without the Atlassian ecosystem baggage. For agencies that want a knowledge base their team will actually use — not just another tool that collects digital dust — Slite's simplicity and AI search make it a strong contender.
