What it does
OnlyFounders is the live network for founders — a place to watch real startups build, ship, and grow in public. Founders host live sessions straight from their dashboard: share progress, answer questions, run polls, and build an audience as they go. No polished demo days, no recap threads — just the actual work, happening live. We're opening up in invite waves — join the waitlist to get early access.

The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
