Swimm IO

Swimm IO is an AI-powered documentation platform designed to keep engineering knowledge continuously up to date and tightly connected to your codebase. Its primary purpose is to help development teams create, maintain, and discover documentation that lives alongside the code, reducing onboarding time, knowledge silos, and context switching. By integrating directly with source control, Swimm IO ensures documentation evolves in sync with code changes rather than becoming stale over time.

Swimm IO analyzes repositories and automatically suggests documentation based on code structure, commits, and developer activity. It supports “live” documentation that is synced to code snippets, so when code changes, Swimm flags or updates the relevant docs to prevent drift. The platform integrates with Git-based workflows (such as GitHub, GitLab, and Bitbucket), enabling documentation reviews as part of pull requests. It also offers rich editors, templates, and code-coupled walkthroughs, making it easier to explain complex flows, architectures, or onboarding paths directly from the code.
