How to use this site
Search above to jump straight to any product’s row, or open a section. Each section opens as a compact, scrollable comparison chart — one row per product — that you can filter, search, and sort. Stars are a 1–5 popularity judgment with a source caption. Cost uses a Free / $ / $$ / $$$ / $$$$ scale with a source caption, rated on the typical individual paid plan most people buy. “Best for” labels are editorial. Official-site links are not affiliate links.
Where the numbers come from
Web-traffic figures are third-party estimates of website visits, not app sessions or unique people. Chatbot shares among seven assistants (October 2026) come from Similarweb: ChatGPT 55.7%, Gemini 24.2%, Claude 11.5%, DeepSeek 3.4%, Grok 2.2%, Copilot 1.1%, Perplexity 0.8%. Most other visit counts are Similarweb estimates for October 2026, as published by SeekTool. A few use Semrush estimates for September 2026 from Tako’s a16z Top 100 table, GitHub star counts, or OpenRouter token rankings. Cost figures come from official vendor pricing pages, checked in November 2026, and are rated on the typical individual paid plan most people buy. If a product has no usable source, the caption says “Editorial estimate.”
What this is not
This is not a vendor ranking you should buy from blindly. It is a starting map for people learning the AI tools landscape. Model versions change quickly; confirm current pricing and terms with the vendor.
