IdeaKiller
ChatGPT pluginValidate startup ideas
IdeaKiller checks a startup or product idea against the live web before you spend months building it.
Ask ChatGPT to validate an idea. IdeaKiller researches demand, competitors, problem fit, economics and risks, then returns:
- a verdict (GO, CONDITIONAL_GO, PIVOT or NO_GO) set by a fixed rule on the scores, not by the model's mood. GO also needs solid research; with thin research the verdict stays CONDITIONAL_GO;
- the weakest point of the idea;
- the evidence behind the verdict, each claim marked as a fact with a source link or as an estimate;
- open questions that could change the verdict;
- one cheap first test to run before building: who to sell to, where to find them, budget, deadline and the number that means "go on";
- when to stop or pivot.
The light check takes about 90 seconds; the full check takes 2-3 minutes, researches deeper and suggests directions to fix the idea. IdeaKiller can also find free domain names built on words people really search for.
Privacy: the idea and the report are deleted after delivery and never used to train models.
