Hack the Hack
Hack the Hack is a project that crawls and analyzes all submissions on DevPost, to predict which idea would win a hackathon. In addition, you can enter your own idea in natural language and it will also estimate the probability of winning for you.
This is a weekend-long hackathon project for Hack the 6ix. Interestingly it predicts itself to have an extremely low winning probability (~4%). And guess what, it did not win the hackathon, just like it accurately predicted.
