# IdeaKiller

> IdeaKiller checks a startup or product idea with live web research in about 90 seconds. It returns a verdict (GO, CONDITIONAL_GO, PIVOT or NO_GO), scores for demand, competition, problem fit, unit economics and risk, the weakest point, evidence marked as fact or estimate, and one cheap first test. It also finds free domain names for the idea.

IdeaKiller works on the website, inside ChatGPT and Claude as an MCP connector, and over a REST API for AI agents. All three use one prepaid balance. There is no subscription.

## Prices

- Light check: $0.50
- Full check: $1.00
- Domain search (up to 10 free domains): $0.50
- A check that fails is refunded. The idea text is deleted after the result is delivered.
