Should you build this?

YES, if

You can ship in 1-2 weeks on $0-20/mo infrastructure
No direct competitors yet — first-mover window open

THINK TWICE

No paid evidence AND no competitors — could mean "no market" rather than "open market"

VALIDATE THIS WEEK

This weekend: DM 5 users who complained — ask if they'd pay $9/mo for a fix (no build yet)
Next 7 days: ship a 2-page landing site with $9/mo waitlist + "request beta" form — count signups
If <10 signups in 7 days: kill it · the demand isn't there at this price
