How we built this list

There are thousands of AI tools, and dozens of new ones appear every week. This list does not try to count them all. It tells you which ones are actually worth your time. Each tool is reviewed with three questions:

  • What is it good for? Real use cases, with examples for online stores, content creation, programming or study.
  • Is it free? We only describe the pricing pattern (free, free with an optional subscription, or paid), because exact prices change quickly.
  • How good is it? Output quality, ease of use and how useful it is in everyday work, including how well it handles languages other than English.

Where the ranking, votes and stats come from

Each tool's "rank" is the di9 team's opinion, based on global usage, quality and usefulness. Two boards, however, are built from real reader data: "Most popular" from your votes, and "Most visited on di9" from clicks on the tools' official links. Voting needs no sign-up, and we keep no personal information about you.

Before you choose a tool

If you are just starting out, read What is a large language model (LLM) and Prompt writing for technical work to get better answers from any tool. To choose between the three main assistants, see ChatGPT vs Claude vs Gemini, and before sharing work data with any tool, read Security and privacy in AI.
