The problem

Why this matters

Most failed products solved a problem nobody had.
AI chat tools agree with you. They rarely tell you the evidence says no.
Research ends up in scattered notes that nobody uses when it is time to decide.
How it works

Research you can click

The coach searches the web before it answers. Every finding comes with its source, so you can check it yourself.

Product thread · ShiftWiseExample
Do small clinics really struggle with shift scheduling?
Coach

Yes, and the evidence is strong. Nurse scheduling is still done in spreadsheets in most small clinics, and last-minute gaps are the top complaint.

Get an interview guide, run the calls, then paste or upload your notes. The coach finds the patterns and the quotes that matter.
