How TechWrit AI turns source into docs
Generic AI tools produce prose about your code. TechWrit AI is a documentation engine: it takes code-aware inputs and returns structured technical documentation, already formatted for your docs framework and checked against your standards.
Code in, structured docs out
Paste source code, configs, or specs. The engine extracts the structure and generates the right doc type for the input — API reference, how-to, runbook, troubleshooting, or release notes — across 17 purpose-built modes.
Standards remembered, enforced, review-ready
Style rules, terminology, and a product glossary are saved with your account and applied to every request — across sessions, contributors, and tools. The first draft is already review-ready instead of an unreviewed AI dump.
Framework-ready output
Pick Trellis Docs, Docusaurus, or Notion and TechWrit AI emits MDX with the correct frontmatter, callouts, tabs, and components. Drop the result into your docs repo — no reformatting.
