AutoScript Sync is a Windows app that reads the motion in a video on your own GPU and writes a funscript for it. It then sends that script to your Autoblow AI Ultra and keeps the device in time with the video while you watch. You don't need a script to exist first, and the video never leaves your PC.
Independent software. Not made, endorsed or supported by Autoblow. It uses Autoblow's public device API.
The Ultra doesn't take a live stream of positions. It takes a whole script through Autoblow's cloud and plays it on the device itself. The app is built around that.
.funscript to Autoblow's API, which converts it
and loads it onto the device. Autoblow keeps an uploaded script for 48 hours,
so sending the same script again inside that window skips the upload.| What the app holds to | Value |
|---|---|
| Fastest movement sent to the Ultra | ~400 units/s |
| Shortest gap between two points | 60 ms |
| Most direction changes per second (Autoblow's published 220 strokes a minute) | 7.3 |
| How often playback is checked against the video | every 1.5–5 s |
| Drift trimmed without a restart | 80–350 ms |
| Drift that restarts playback at the video's position | over 350 ms |
| How long Autoblow keeps an uploaded script | 48 h |
Units are funscript positions, 0–100. The first three rows are the app's Autoblow AI Ultra device profile; you can narrow the stroke range and intensity further in Stroke Settings.
Light blue and it still won't connect? Check the token at fun.autoblow.com, Autoblow's own site. If it fails there too, copy the token from the setup page again.
Generating runs on your own machine. Pose tracking and optical flow follow the motion in the scene, and an optional depth model reads movement toward and away from the camera in POV scenes. On an NVIDIA card this takes minutes for a full video. It also runs on the CPU, more slowly.
Already have a script? If a .funscript with the same name sits
next to the video, the app loads it instead of generating one, and the Ultra
plays that.
You can check what the AI produced before you send it: the timeline shows every stroke, and you can amplify, soften, shift or re-analyse any stretch. See the guides for the full workflow.
The same app also drives The Handy, Kiiroo, Lovense and OSR devices through Intiface. See every supported device.
Yes. Autoblow's cloud API accepts a .funscript upload, converts it,
and the Ultra plays it. AutoScript Sync does that upload for you and keeps
playback in time with the video.
No. AutoScript Sync writes one from the video. If a .funscript with
the same name already sits next to the video, it loads that one instead, so
scripts you already have work too.
No. The video is analysed on your own PC. What goes to Autoblow's cloud is the script, a list of timestamps and positions, because that is how the Ultra plays scripts.
For the Ultra, yes: the device is controlled through Autoblow's cloud, so both the PC and the Ultra need to be online while you play. Generating a script runs locally and does not need the internet.
The Ultra powers on offline every time, with a solid white light. Hold its button for about 3 seconds, release when the LEDs blink white rapidly, and wait for them to turn light blue. If it still fails with light-blue LEDs, check the token at fun.autoblow.com. One red LED means the device cannot reach the internet through your Wi-Fi.
Video script sync should work. Manual mode, oscillate and Test Stroke are Ultra-only controls and will not. The app is built and tuned for the AI Ultra.
Use Offset in the app: a positive value if the device feels late, a negative value if it feels early. The app also measures the delay to Autoblow's servers and compensates when playback starts.
No. AutoScript Sync is independent software. It is not made, endorsed or supported by Autoblow; it uses Autoblow's public device API.
