How this tool works

You type a keyword and the tool queries Google's autocomplete (the Google Shopping surface) to pull every suggestion Google would actually display in the search bar. It loops over A through Z and about 17 intent modifiers (how, why, best, vs, near…) to mine the long tail, and grabs a real popularity score for each suggestion along the way.

No key, no account, the endpoint is public. Results are cached on the server for 6 hours per seed so re-running the same keyword doesn't pay the network cost twice.
