Over 1,900 participants took part in the the ever first AI21 Labs Hackathon, with 24 different projects competing for the first prize.

The winner of AI21 Labs’ first ever hackathon is Rahel Gunaratne, who nabbed the first place prize with his WebIndexer project - An AI-based question-answering tool designed to help users find specific information using questions instead of keyword search within a webpage. WebIndexer can be integrated into any website, offering users a much-needed solution to the slow and tedious process of keyword search, and can serve as a valuable alternative to both ChatGPT and traditional search bars like Google.
