ReA — Documentation Intelligence

Hover over any function to instantly see its docs. Browse your entire codebase in the sidebar. Generate missing docs with AI.

ReA indexes your workspace, extracts JSDoc/docstrings/rustdoc, and surfaces documentation exactly where you need it — without leaving the editor.

Hover tooltip showing function signature, parameters and description

Core features — indexing, hover, sidebar, IntelliSense — work fully offline. No account required.

Features

Sidebar browser with function tree grouped by file

Hover documentation — move your cursor over any function to see its signature, parameters, and description
Sidebar browser — navigate all documented functions in the ReA activity bar panel, grouped by file
IntelliSense integration — completion suggestions and signature help powered by your indexed docs
Diagnostics — highlights undocumented functions and @param mismatches as you type
AI doc generation — generates docs for undocumented functions via local Ollama (no quota) or Reatomize proxy
Analytics dashboard — documentation coverage %, debt view, and heatmap; export to Markdown
Local sync — export/import docs as .rea-docs.json to share with teammates or use in JetBrains
Cloud sync — push and pull docs across machines with a Reatomize account
Auto-indexing — incremental re-index on startup; only changed files are re-processed
20+ languages — TypeScript, JavaScript, Python, Rust, Go, Java, C/C++, C#, PHP, Ruby, Swift, Kotlin, and more

AI generation uses your local Ollama instance when available (no quota consumed). The proxy is used as a fallback.

TypeScript · JavaScript · Python · Rust · Go · Java · C · C++ · C# · PHP · Ruby · Swift · Kotlin · and more

ReA's core features — indexing, hover, sidebar, IntelliSense, diagnostics, local sync — run entirely on your machine with no network requests.

The following features connect to external services:

Feature	Service	When
AI generation (fallback)	`api.reatomize.com`	When local Ollama is unavailable and `rea.ai.enabled = true`
License validation	`api.reatomize.com`	On activation and periodically
Auth	`accounts.reatomize.com`	On `ReA: Sign In`
Cloud sync	`api.reatomize.com`	On `ReA: Sync Docs to Cloud` (manual)

To keep ReA fully local: run Ollama locally and do not use cloud sync.

ReA is built by Reatomize — a developer tools company focused on making codebase documentation effortless.
