A real answer from the archive
Should you start an AI startup solo or with a co-founder?

The Case for Co-founders:...

Questions
What is Taffy and what does it cost?
Taffy searches the transcripts of 19 founder YouTube channels, including Y Combinator and a16z. Ask a question and the answer cites the episode and the minute. It is best for founders who build with AI. You get 2 questions free with no account, then 5 a day signed in. Pro is $9 a month for unlimited questions.
Why not just ask ChatGPT?
ChatGPT can't reliably read a video, so it answers from memory. Taffy answers from the transcripts it has indexed, and cites the episode and the minute.
Who is Taffy for?
We didn't build Taffy for people who watch every episode. We built it for the builder with a question today and a backlog of episodes they'll never finish.
What if nothing in the archive covers it?
Taffy answers only from what the creators in your topic said. It never makes up a quote, a creator or a timestamp, so a thin answer means the archive is thin on that question.
