Best form builders for user research

The short answer: Typeform is the strongest research form if you can pay for it, and its AI reading of written answers starts on Growth plans. Fillout and Tally are the free picks with solid branching. Enform fits small teams whose real problem is reading the written answers. Dovetail is where research lives once you've collected it, but it doesn't send surveys.

Research forms depend on two things: logic that adapts to the last answer, and long open-ended questions where the real reasons show up. A builder that's great for event signups can be a poor fit if every written answer lands in a column for you to read.

The shortlist

Ordered by fit for user research: branching that follows what someone just said comes first, then room for long answers, then help reading those answers afterwards.

Checked on against each tool's own pricing and help pages, linked under each tool. Enform is our product.
