Free customer research tools
Twelve tools we built because we needed them. No email gate, no signup, no data sent anywhere. The calculators do real math and show the formula. The templates download as markdown so you can put them straight into your docs.

Open tool →Why these are free
Straightforwardly: these are useful on their own, and some people who use them will want the thing they cannot do alone, which is actually talking to their buyers at scale. A sample size calculator tells you to interview 385 people. It does not go and interview them.
That is what Gather does. If the tools are all you need, take them and go, that is fine.
The tool gives you the math. We give you the answers.
Gather runs the research, then keeps what buyers said in a model your whole team can query.
