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

Pain level is LOW — users may not pay to fix this
Only 1 mention across platforms — evidence thin, validate before building
No paid evidence AND no competitors — could mean "no market" rather than "open market"

VALIDATE THIS WEEK

This weekend: DM users at github (1 complaint) — ask if they'd pay $9/mo for a fix
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

I want to build a tool for: LangChain users requesting RunnableFactChecker for post-generation verification in RAG pipelines (signal#1)

The pain users describe: Add RunnableFactChecker for post-generation verification in RAG pipelines

Timing / why now: [no explicit trigger]

Existing alternatives: none clearly identified yet — opportunity for a first-mover

Help me draft an MVP technical plan:
1. Core user flow (happy path, 3-5 steps)
2. Data model (main tables and their key fields)
3. Tech stack recommendation (favor fast-to-ship options)
4. First 3 things to build this weekend
5. What NOT to build in v1 (scope discipline)
