Who AI recommends / API development & documentation

Which API & docs tools does AI recommend? (2026)

Buyers now ask AI assistants which API & docs tools to use. Every week we ask Google Gemini the same questions and record which brands it recommends, in what order, and how visible each of them is to AI search.

Gemini answers refresh weekly. This week's answers for API & docs tools aren't available yet, so below is our AI visibility leaderboard for the category instead. Check back soon, or run your own check now.

FAQ

Which questions did you ask?

Two typical buyer prompts: "What are the best API & docs tools for a small team in 2026?" and "Which API & docs tools would you recommend for a startup on a budget?". We ask Google Gemini through its official API and refresh the answers weekly.

Is this a ranking of the best products?

No. It records what one AI assistant said when asked, in the order it listed them. Other assistants such as ChatGPT, Claude or Perplexity, or the same assistant on another day, can name different products.

What is the AI visibility score next to each brand?

It comes from RankRoot's AI Visibility Index: a crawl of each product's homepage that checks AI crawler access, answer-ready content, structured data and agent readiness, scored 0 to 100. Brands we have not crawled show as not in our index.

My product isn't on this list. How do I check if AI mentions it?

Run a free AI mention check at https://getrankroot.com/ai-mentions: we ask Gemini the questions your buyers ask and show whether it names you, where it ranks you and who it recommends instead.
