Each tool is a page of its own: enter your event's numbers and read the result, with pointers on how to interpret it.
Free
Every tool in this list is free to use: no payment and no card required.
No sign-up

The calculation is explained
Every page has a "How it works" guide and frequently asked questions. Where the calculation uses public data, the page cites the source and its date.
Declared estimates
AI tools tell you how to read the result: whether it comes from typical industry cases, from average values or only from your data. It is a starting point, not a forecast.
