How to read a profile
Each profile opens with an answer in brief and a fact box. The fact box gives the price and the free option as the tool's own site states them, and the date we read that site. The Sources list at the end links every page we used.
We do not rate or score other tools. Where a profile names a limit, the tool's own pages state it. Prices and free tiers change often, so open the tool's pricing page before you pay. The methodology page explains how we check each fact.
If you only want to know what you can get for free, the free AI idea validators page puts every free tier side by side.
