Claude says your idea is great. This plugin tries to kill it.

A real run, sped up
An AI receptionist for US dentists: 19 searches, 34 sources, the verdict, then the report and the dashboard. Every line comes from the run's log.
Real reports
These are ideas we actually evaluated with the plugin. Each report shows its sources, its metrics and how the idea could be saved.
How it works
The most common use: paste a viral "I make $10k/month" thread. It checks every claim, names what the author sells and redoes the math. Or type kill my idea: … for your own idea.
It hunts for kill shots
A free alternative, direct competitors, people who already failed, no channel, costs that eat the margin, weak demand, legal risk, a saturated wave of look-alike launches. At least 20 sources, each tagged primary, secondary or tertiary.
It measures and scores
Market size, CAC, LTV, payback and break-even, country by country. Then 21 sub-scores against a fixed rubric, six fixed rules that block a false GO, and a confidence level.
It shows a way forward
Rescue paths with their projected score and difficulty, and the cheapest test you can run in 7 days.
It fact-checks money tweets
/kill-my-idea:check-tweet checks every claim, redoes the math with real fees and names what the author is selling.
It gives you a card to share
Every report has a Share card button that downloads a PNG verdict for X, LinkedIn or Reddit. It's drawn locally; nothing is uploaded.
It checks its own math
A checker recomputes every score from its sub-scores, applies the rules and audits the sources before you see the verdict. Reports are hardened and come in English or French.
