How this was made
What to keep in mind
- The thread only became monthly in 2024, so early periods are small samples.
- Topics and project details come from a language model reading each answer. Individual labels can be wrong.
- Threads with fewer than 15 comments and threads about a narrower topic, such as non-AI products, are left out. Threads were found by title, so a few with unusual wording may be missing.
- Founder status is only as fresh as the sources found. Where no recent source turned up, the entry says so.
