Founded in 2019, Swimm is an AI-powered code documentation platform that ties written docs directly to the code snippets they describe. Its patented Auto-Sync engine runs inside a team's CI pipeline, automatically fixing minor code drift in existing docs and flagging bigger changes for a developer to review before merge.
About Swimm
Swimm was founded in 2019 by Oren Toledano, Tom Ahi Dror, Omer Rosenbaum, and Gilad Navot, with engineering based in Tel Aviv and a commercial presence in New York. The company has raised $33.3 million, led by Insight Partners with participation from Dawn Capital, Pitango First, and TAU Ventures. Swimm calls its approach Code-Coupled Documentation: rather than a wiki that lives apart from the codebase, each doc page is anchored to the specific lines of code it explains, so the two move together as engineers work. That structure is also what makes Auto-Sync possible, since the system always knows which code a given doc is tied to.
Pricing
Free: 5 users, 1 private repo. Teams: $17.78/seat/month. Enterprise Starter: $28/seat/month. Enterprise: custom pricing.
Key Features
- Real-Time Documentation Sync: Automatically updates documentation when code changes, preventing stale docs with deep codebase analysis.
- IDE-Integrated Editor: Create, edit, and read documentation directly in VSCode, JetBrains, and other IDEs without context switching.
- AI-Generated Auto-Docs: Auto-generates documentation for legacy codebases across all programming languages using code analysis.
- Code Knowledge Base: Centralizes code knowledge with linked documentation, diagrams, and code snippets for faster onboarding.
- Enterprise Integrations: Connects with GitHub, GitLab, Bitbucket, Azure DevOps, and CI/CD pipelines for connected workflows.
Pros
- The main reason reviewers stick with Swimm: once a repo is connected, docs update through CI instead of relying on someone remembering to edit a wiki.
- Eliminates 75% of the time engineers spend answering repeat questions, since the AI-powered knowledge base surfaces linked docs directly in context.
- Integrates directly into 5+ IDEs and Git platforms, so documentation stays synchronized with code without a separate publishing step.
Cons
- Free tier limited to 5 users and 1 private repository, forcing teams to upgrade quickly.
- AI documentation generation quality varies depending on codebase complexity and legacy code age.
- Steep learning curve for teams unfamiliar with documentation-as-code practices.
Data Handling
- Compliance
- SOC 2 · ISO 27001
Frequently Asked Questions
What does Swimm actually cost?
Swimm has three paid tiers on top of a free plan: Teams costs $17.78 per seat per month for shared workspaces and team-wide Auto-Sync, and Enterprise Starter runs $28 per seat per month for advanced admin and security controls. A custom Enterprise plan adds SSO, dedicated support, and on-prem deployment, quoted directly through sales. Annual billing cuts the per-seat rate by roughly 10% compared to paying monthly.
What do you get on Swimm's free tier?
Up to 5 users and 1 private repository come free, with core Code-Coupled Documentation and Auto-Sync included at no cost. Team-wide administration and the advanced security controls stay reserved for Teams or Enterprise Starter, but there's enough room for a solo developer or small project to test Auto-Sync against a real repo before a wider rollout.
What are Swimm's closest competitors?
The closest match on Hokai is Scribe, which builds step-by-step SOPs from recorded screen actions rather than syncing docs to source code; pick it for onboarding guides aimed at non-engineers. Tango offers a similar screenshot-based workflow for business processes. Teams that need documentation tied to a live codebase and enforced through CI have no direct on-Hokai substitute for Swimm's Auto-Sync model.
What separates Swimm from Scribe?
Swimm and Scribe solve different documentation problems: Scribe captures clicks and screenshots to auto-generate step-by-step SOPs for non-technical workflows, starting at $23 per user per month on its Pro Personal tier. Swimm instead ties docs directly to code snippets and keeps them current through CI-integrated Auto-Sync, with Teams pricing usually undercutting Scribe's equivalent plan. G2 reviewers give Swimm a 4.4 average across 27 reviews, most citing how easily its docs stay current as the standout strength. Pick Swimm for documentation that lives inside a codebase and changes with it; pick Scribe for UI-based business processes aimed at non-engineers.
How long does it take to get going with Swimm?
A first doc can go live within one sitting: connect a GitHub, GitLab, or Bitbucket repository through Swimm's GitHub Marketplace or VSCode extension listing, then write it directly in the IDE. Most teams start with a single high-traffic module or onboarding guide rather than documenting an entire repo on day one, and Swimm's own documentation site walks through connecting a repo and setting up Auto-Sync rules for that first project.
Top Alternatives
- Scribe: Documentation that must trace directly to source code and update through CI stays with Swimm; annotated screenshots for onboarding non-technical staff stay with Scribe.
