Started my Market Fit Canvas session by just typing "Product Market Fit" and nothing more.
Claude already had context on what I'm building, so it asked me 3 questions about what I'm actually experiencing right now. I picked one, and it ran a 5-second test on the spot. Then it asked if I wanted to properly stress-test this by walking through the full Market Fit Canvas.
Because Claude already knew who I'm building for, I could just confirm or correct instead of explaining from scratch. Everything it surfaced was stuff I already knew I just couldn't get my brain to write about it or hang together coherently. Having that context already loaded made it easy to keep building block by block.
Ended up with a Market Fit Canvas score of 88/100.
The fact is claude knew everything about for whom i am building, made it easy for me to pick and help me continue to build a proper Market fit canvas. Maybe if you could see this...you would be able to make sense of what I am saying...
