market-finder

market-finder is a private research tool built and used by one person. It gathers public signals about software markets (what people complain about, what they search for, what already sells) and summarises them to help decide which products are worth building.

It runs on its author's own computer. It has no user accounts, is not offered as a service, and shares no data with anyone.

It uses the Google Ads API to read keyword search volumes for its author's own Google Ads account.
