What Is Swimm?
Swimm is an AI-powered documentation tool keeping code documentation in sync with code changes, detecting when code changes and automatically updating documentation accordingly, with PR-based documentation and AI-assisted doc creation. Pricing runs a free plan (up to 5 users), Teams at $16/month (up to 30 seats, AI doc creation assistance), Enterprise Starter at $28/month (AI-powered contextualized code understanding), and a custom Enterprise plan — integrates with GitHub, GitLab, and Bitbucket with real-time collaboration and smart suggestions.
Its core value proposition — automatically detecting code changes and updating documentation to match — addresses a genuinely universal and persistent pain point in software development: documentation that goes stale the moment code changes, which most teams struggle to keep current through manual effort alone, making Swimm's automated sync a real solution to a problem virtually every engineering team faces.
It's aimed at development teams wanting documentation that stays accurate as code evolves, with the free tier's 5-user cap providing genuine access for small teams before Teams' $16/month unlocks AI doc creation assistance for up to 30 seats — Enterprise Starter's contextualized code understanding specifically serves teams wanting deeper AI comprehension of their codebase beyond basic sync detection.
