FunGen generates funscripts from 2D and VR video with AI, entirely on your own machine — nothing is uploaded. It is also a full frame-accurate, multi-axis funscript editor and player, so you can build a script by hand, clean up what the AI generated, and drive your device straight from the timeline.
The current release is FunGen 2: a single native binary for Windows, macOS (Apple Silicon native) and Linux — no Python, no venv, no dependencies to chase.
- AI generation for 2D and VR — fisheye, equirectangular, side-by-side and top/bottom, up to 8K, tracked on your GPU
- Frame-accurate multi-axis editor — stroke, surge, sway, twist, roll and pitch on one timeline
- Plays straight to your device — The Handy, OSR2 / SR6, Autoblow, and anything on Buttplug.io / Intiface
- Runs entirely on your own machine — AI generation is local, nothing is uploaded
- Free to download — no account, no card
