Mintlify Doc Writer for Python, JavaScript, TypeScript, C++, PHP, Java, C#, Ruby & more

Generates language-specific docstrings by analyzing selected code or the current line, sending the code context to Mintlify's remote AI service which returns formatted documentation matching the detected or user-preferred docstring convention (JSDoc, reST, NumPy, Doxygen, Javadoc, GoDoc, etc.). The extension parses the response and inserts the docstring inline at the cursor position, preserving indentation and code structure.

Supports generation of docstrings in multiple standardized formats (JSDoc, reST, NumPy, DocBlock, Doxygen, Javadoc, GoDoc, XML, Google style) for the same code block, allowing teams to enforce consistent documentation conventions across polyglot codebases. The extension detects the target language and applies the appropriate docstring syntax, enabling format switching without re-writing documentation content.

Integrates into VS Code's command palette system, allowing users to invoke documentation generation via keyboard shortcut (Ctrl+. on Windows/Linux, Cmd+. on macOS) or by searching 'Write Docs' in the command palette. The extension hooks into VS Code's editor context (current file, cursor position, selection) to determine the target code block and trigger the remote documentation generation pipeline.

Sends selected code to Mintlify's remote API where an AI model analyzes function signatures, parameters, return types, and logic flow to synthesize contextually appropriate docstrings. The model infers parameter descriptions, return value documentation, and exception handling based on code structure, then returns formatted docstrings that the extension inserts into the editor. Code is transmitted over HTTPS and Mintlify claims not to store code permanently.

Offers a freemium pricing structure where basic docstring generation is available for free to all users, with premium features (likely including higher API rate limits, priority processing, or advanced customization) available through a paid subscription. The extension is installable from the VS Code marketplace at no upfront cost, with monetization through usage-based or subscription-based premium tiers.

Automatically detects the programming language of the current file (Python, JavaScript, TypeScript, Java, C++, C#, PHP, Ruby, Rust, Dart, Go) and inserts generated docstrings using the correct syntax and indentation for that language. The extension parses the code context to identify function/method boundaries and inserts docstrings at the appropriate location (before the function definition, with correct indentation and line breaks), preserving code structure and formatting.

Analyzes function signatures (parameter names, type annotations, default values) and return type declarations to automatically generate parameter descriptions and return value documentation in the docstring. The AI model infers semantic meaning from parameter names and types (e.g., 'user_id: int' → 'The unique identifier of the user') and generates appropriate documentation without requiring manual parameter analysis.

Inserts generated docstrings directly into the current file at the cursor position or above the selected function, without requiring navigation to external editors, documentation files, or separate UI panels. The extension modifies the current file in-place, allowing developers to immediately review and edit the generated docstring without context-switching.
