Swimm integrates documentation directly into the IDE where developers spend their time, providing contextual walkthroughs and explanations alongside the code they reference. When a developer opens a file or function, relevant Swimm documents appear as inline hints, offering explanations of design decisions, usage patterns, and dependencies without requiring a context switch to external documentation tools.
The auto-sync capability monitors code changes and detects when existing documentation becomes stale. If a function is renamed, parameters change, or code is moved, Swimm alerts documentation owners and suggests specific updates needed to keep docs accurate. This continuous verification addresses the fundamental problem that static documentation inevitably drifts from the code it describes.
Swimm offers a free plan for individuals and small teams with paid enterprise features including advanced analytics on documentation coverage, team onboarding workflows, and SSO integration. The platform integrates with VS Code and JetBrains IDEs as well as GitHub for PR-triggered documentation checks.
