Free tools that pair with your forms

Every tool on this page solves a small, real problem you hit when collecting feedback: How many people do I need to survey? Is my NPS any good? Are these two results actually different, or is it noise? Which campaign drove those responses? None of them require an account, none of them email you a PDF, and your data never leaves your browser for the calculators.

They also work better together. Start with the survey question generator to draft your questions, check the sample size calculator to know how many responses you need, collect answers with a form built by AI, then come back to calculate your NPS, CSAT, or statistical significance.

And when you're ready to collect responses, Fomr is the form builder behind these tools: unlimited forms, unlimited responses, and full design control on the free plan.
