DocuWriter vs Theneo
Both stand on ai documentation generators. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
DocuWriter combines code analysis, documentation output, and reviewable update suggestions. The trial is limited to 10 AI-generated pages, and ongoing generated-page use consumes credits.

Choose Theneo if you need API documentation with collaboration, supported API formats, and options for private customer portals. Its free Starter plan offers a way to begin, while larger endpoint or team limits and self-hosting call for higher-tier plans. Look elsewhere if your budget requires a published Enterprise price or your team needs more than the Starter limits without a paid plan.
