TechWrit AI
TechWrit AI is a hosted writing tool that turns source material into structured technical and UX documentation. It accepts source code, configuration files, API specifications, Markdown, plain text and Word documents. Seventeen purpose-built modes cover technical and UX writing; Code to Docs can create API and developer documentation, including OpenAPI YAML. Writers can set style rules, terminology substitutions, glossary terms, prompts and custom instructions, then format output for Trellis Docs, Docusaurus or Notion. Access is available on the web, through an API and as a VS Code extension. Documented workflows include GitHub Actions pull-request checks and an MCP server for Claude Desktop, Claude Code, Cursor and VS Code. The free plan allows 20 requests monthly. Pro costs $19 a month, or 15.00 USD monthly when billed annually, and Team costs $24 per seat monthly, or 19.00 USD annually, with a two-seat minimum.
