The order near the top is decided by reliability rather than benchmark scores: how often a model holds a long document in context, how honestly it reports a source, and how gracefully it fails. The expensive tiers only pay for themselves if you routinely work past the free limits.

Widest feature surface of any assistant
A horizontal assistant that covers the widest range of everyday tasks. It is not the cheapest option at the top tier, but it is the one most teams can adopt without changing how they already work. Choose it when you want one subscription to cover writing, data, images and code rather than five specialised tools.

What each one costs
Free means the tool can be used without paying. Where a paid price is missing the official page did not publish a fixed number — check it there rather than trusting a comparison table.
AI Chatbots: the questions that actually decide it
Why is the most popular assistant not always ranked first?
Popularity is not one of the six dimensions. A tool gains points for feature depth, reliability and value, and loses them for opaque usage caps. The breakdown on each review page shows exactly where it lost.
Are free tiers enough for daily use?
For light use, yes — several assistants reset daily rather than monthly. The limits that actually bite are file uploads and long-context requests, not message count. If your work involves attached documents every day, assume you will pay.
How this ranking is built
Six dimensions with fixed maximums, adding up to 100. The weights do not change between tools, so two listings are directly comparable. A dimension with no reliable data is dropped from the total rather than filled with a default.
Ranking order is score first, then name. It is not influenced by partnership or referral terms. See the full cross-category ranking, or browse the AI Chatbots directory with filters and task lists.
