Theneo

Writing and publishing API documentation without doing it all by hand is the job Theneo takes on. Theneo is an AI API documentation tool that generates docs and developer portals, with an assistant called TheneoAI that helps you build the docs.

Readers get GPT-powered search over what you publish, an API Explorer, and automatic changelog documentation.

The free Starter package covers 1 public project, 2 private projects and up to 20 team members, with a capped number of AI assists and search results.

It also includes project access management and analytics with feedback.

That is enough to test it on a real API.

Paid plans start at $120 per month per workspace for Business, which raises the limits to 7 projects and 50 members and makes AI use unlimited.

It adds custom branding, SEO settings, a custom domain and design templates.

Growth costs $400 and adds custom CSS, ChatGPT prompt configuration, IP whitelisting and up to 20 developer hubs.

Enterprise pricing is custom and brings self hosting, SAML SSO and custom roles.
