TimingBased on trigger event count, event freshness (14d window), and growth forecast. Percentile against all active cards.
25(weak)
SeverityBased on pain intensity level, mentions (full-corpus percentile), and paid-evidence count (log scale).
62(moderate)
FeasibilityBased on existing supply count (inverse percentile — less supply = higher feasibility), build difficulty, and source diversity.

29d old Top tier Demand + Supply + Trigger all present
How we calculated this 57/100
25×30% + 62×45% + 90×25% = 58 → × 1.00 freshness → × 1.00 gold = 57
Final score discounts: freshness drops ~50% per week (29d old), and grade weight reflects how many of the 3 signal types (demand/supply/trigger) we found.

Should you build this?

YES, if
  • You can ship in 1-2 weeks on $0-20/mo infrastructure
THINK TWICE
  • 4 competitors already shipping — crowded, harder to differentiate
VALIDATE THIS WEEK
  1. This weekend: DM 5 of the reddit:claudecode users who complained — ask if they'd pay $9/mo for a fix (no build yet)
  2. Next 7 days: ship a 2-page landing site with $9/mo waitlist + "request beta" form — count signups
  3. If 10+ signups: build the smallest version that solves the top 1 pain — defer the rest

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)
