Cause of death: the autopsy

The research expected it to fail because PDF24 already converts for free with AI; the test was cheap. A fake door with the price showed under a real upload box: after 14 days, 23 ad landing visitor-days, 3 PDFs read and 0 clicks on the paid button. Removed on 2026-10-13; the free page now links the create form.

The numbers

None. It was never built, so there are no visitors, sales or ad spend to count. It died on paper, which is the cheapest place to die.

Could rise again if

The report left no way back.
