I built Prexist to solve a frustration I kept running into —> not knowing if my “brilliant” idea already existed… until it was too late.

What Prexist does: * Search 8+ platforms in one click * See similar products with AI powered analysis * Get suggested keywords and relevance scores * All in a clean, unified interface

Built for: * Founders validating startup ideas * Product managers doing competitive analysis * VCs and consultants doing due diligence

Save hours (or days) of manual research, find out what already exists before you build.

Would love your feedback, ideas, and support If you like it, please give it an upvote and share it with someone who’s building something new!

Nice idea and nicely put together - you might be getting hugged to death right now, but the search never completed for me (and on chrome/android the searching text was overplayed strangely with the names of the places you were searching).

Might be night to have an 'explore' option or something which shows you around a little more? Obviously though recent searches would be very very interesting, I assume many people would be put off by that!

This is useful but not to decide whether to work on an idea or not. Most initial ideas are going to exist somewhere around the world but they may not focus on the angle that we are interested in. So, I think this is more useful as a way to understand existing approaches and see if our insights can lead to a meaningfully different solution.
