CAPABILITIESFeatures<br>AI provider disclosure: DocFlow combines deterministic AST parsing with DeepSeek's deepseek-chat model for draft generation. Generated documentation is presented for developer review before use.
PR-Triggered Auto-Documentation<br>After every PR merge, DocFlow automatically analyzes the diff and generates documentation updates, keeping your docs synced with every ship.
git merge main
AST + DeepSeek LLM Hybrid Engine<br>AST analysis extracts exact function signatures, parameters, types, and class structures. DocFlow's current production AI provider is DeepSeek, using deepseek-chat by default for natural-language documentation drafts.
struct Node {<br>type: AST_TYPE,<br>body: string
Incremental Processing<br>DocFlow is designed to analyze changed files in a PR instead of the entire codebase, reducing unnecessary processing.
PR Comment Preview<br>DocFlow posts a PR comment showing exactly what it will change. You review and edit before anything lands on main.
Automatic Changelog<br>Every PR gets a semantic changelog entry generated from commit messages plus deep code analysis.
Multi-Language Support<br>Python, JavaScript, and TypeScript at launch. Go, Rust, and Java coming next to cover the full developer stack.

What languages does DocFlow support?Python, JavaScript, and TypeScript at launch. Go, Rust, and Java are planned next. DocFlow uses AST analysis to help documentation follow code changes, but generated output still needs review.
Does DocFlow store my code?DocFlow is not designed to store full repository source code. It may store repository metadata, configuration, generated documentation, and processing history, and it processes the code context needed to generate docs. Relevant context may be sent to DeepSeek, the current production AI provider.
Which AI model or provider powers DocFlow generation?DocFlow's current production configuration uses DeepSeek as the AI provider, with deepseek-chat as the default model. DocFlow first extracts code structure with AST analysis, then sends the...
