AI document summaries

It often takes a lot of time to figure out whether a request is truly relevant. Soon, AI will take over that task for you, automatically, right within your own 12Build environment.

This functionality summarizes project documents, automatically extracts the most important information, and shows you within seconds whether a request is a good fit for you. That way, you no longer waste time on irrelevant documents, you get instant clarity, and you can decide faster and more precisely whether to submit an offer.
