Pain points, ranked

How Painfinder works

Based on the research trick founders use: don't invent problems — aggregate the ones real buyers are already complaining about.

01

Aggregate the gripes

It gathers the complaints buyers commonly leave about your niche or a specific competitor, and ranks them by frequency and pain.

02

Point you to the proof

For each pain it tells you exactly where to verify it — which YouTube videos, subreddits, review sites, and forums to read the comments on.

03

Turn pain into features

Every complaint becomes a concrete feature idea, so your version one is built around a gap people already feel.

Questions, answered

Is Painfinder really free?

Yes — free, no signup. Enter a niche or competitor and get a full research brief. Fair-use limits keep it running; paste your own API key to skip them.

What do I get back?

A ranked list of real customer pain points, each with a heat rating, the underlying complaint, a realistic example of how buyers phrase it, exactly where to go verify it, and the feature idea it points to — plus a short list of the best places to read the raw comments yourself.

Why mine complaints instead of surveys?

Because people are most honest in the comments of content they didn't expect to be researched. Aggregating that unfiltered feedback beats asking people what they think they want.

Does it work on a single competitor?

Yes. Enter a competitor's name and it focuses on what their users specifically complain about — your openings for a simpler, cheaper, or more focused alternative.
