I have been hacking together a poor-man's crunchbase that's fueled by GPT.
React / Python / Supabase. The most interesting piece thus far has been the success of the self-correcting loops through GPT. At each turn basically feeding the results back to another 3.5 prompt that is only about reviewing quality. I found that with these loops you can get solid results without having to use the more expensive GPT4 API.
(Also loving all the projects in this thread)
