Questions

Will it be free?

Yes. Supporters on Patreon will get new features a little early, and everything opens up to everyone later.

Where does the quick look get its numbers?

From the replay files themselves, worked out the way the app works them out: the same badges, your numbers beside Plat+ ranked players, L-cancels, techs, wavedashes, SDI and how each stock was lost. The ranked numbers are the app's own, from public Slippi ranked games. The app adds the moments and simulations on top.

What is the AI in the simulations?

The simulations use vladfi1's slippi-ai models, trained on ranked Slippi games, running on enzyme's melee-sim-light. Both characters are played by the models from the moment on.
