An honest comparison of HaptiQ and FunGen for AI funscript generation: cost, hardware requirements, workflow, device playback, and which tool suits your setup.
If you're looking for an AI tool that turns video into a synchronized funscript, you'll run into two names quickly: FunGen and HaptiQ. Both take a VR or 2D POV video and produce a .funscript file automatically, and both can save you the hours it takes to script a scene by hand. But they're built around very different philosophies — one is a free, open-source desktop application you run entirely on your own hardware, and the other is a hosted service that runs in your browser (with a native iOS app) and connects directly to your devices.
This is an honest head-to-head. We build HaptiQ, so we'll be upfront about that — but the truth is that each tool genuinely fits a different kind of user, and picking the wrong one for your situation leads to frustration either way. Here's how to decide.
Both produce standard .funscript files, so nothing you make in either tool locks you in. Plenty of people try both.
FunGen is a free, open-source funscript generator that runs as a desktop application on your own computer. All processing happens locally: your video never leaves your machine, which is a real privacy advantage, and there are no accounts, tiers, or usage limits. The open-source model also means the community can inspect the code, contribute improvements, and fork it.
The trade-offs follow directly from that design. Because the AI inference runs on your hardware, you need a reasonably capable machine — generation speed depends entirely on what you own, and older or low-power computers will struggle. It's desktop-only, so there's no way to kick off a job from a phone or tablet. And as with most open-source tools, installation, updates, and troubleshooting are on you: you're your own support team.
HaptiQ is an AI-powered funscript generator that runs in the browser at haptiq.app, with a native iOS app as well. You upload a VR or 2D POV video and a 5-stage machine-learning pipeline handles the rest: frame extraction, OpenCV optical-flow motion detection, region-of-interest analysis, funscript generation, and post-processing. Progress streams live to your browser over WebSocket, with per-stage updates — no refreshing, and no wondering whether the job died.
Because the heavy lifting happens server-side, your own hardware doesn't matter. A years-old laptop, a Chromebook, or an iPhone can all produce the same script. HaptiQ also goes beyond generation: there's a built-in timeline editor with 20+ keyboard shortcuts, rubber-band selection, and 14 transform plugins for cleaning up or reshaping a script, plus multi-axis T-code support across 8 axes (L0–L2, R0–R2, V0, A0) for multi-axis rigs like the OSR2+ and SR6.
The other big difference is playback. HaptiQ has a device index of 872 devices (806 of them Bluetooth LE) and can drive them directly: Web Bluetooth in Chrome or Edge with no extra software, Buttplug.io v3 over raw WebSocket (with Intiface Central for some devices), The Handy over WiFi or cloud (HAMP, HDSP, and HSSP modes), and JoyHub via cloud relay. You can generate a script and play it on your hardware without ever leaving the app.
HaptiQ has Free and Pro tiers, so unlike FunGen it isn't free-everything-forever — but you can generate scripts without paying anything to see whether the output quality works for your content.
FunGen wins on sticker price: it's free and open source, full stop. HaptiQ has a free tier for getting started and a Pro tier for heavier use. If budget is the only variable, FunGen is the answer — though it's worth counting the hidden cost of the hardware it needs. If you'd have to buy or upgrade a GPU-equipped machine to run FunGen well, the math changes.
This is the sharpest divide. FunGen needs a capable local machine and some willingness to install and maintain desktop software. HaptiQ needs a browser — Chrome, Edge, Firefox, or Safari for generation and editing (device connections via Web Bluetooth specifically require Chrome or Edge) — or an iPhone. If the phrase "check your GPU drivers" makes you close the tab, HaptiQ is the safer bet. If it makes you feel at home, FunGen will treat you well.
FunGen has the structural advantage here: local processing means your videos never leave your computer. With HaptiQ, video is uploaded for processing, as with any cloud service. If keeping content strictly on your own machine is non-negotiable, that alone may decide it for you.
FunGen covers generation; for editing you'll typically move the output into a separate script editor, and for playback into a separate player and device bridge. HaptiQ keeps the whole loop in one place: generate, fix up problem sections in the timeline editor with transform plugins, then connect a device and play — or export the .funscript and use it anywhere. Exported scripts work with the third-party players you'd expect: DeoVR, HereSphere, XBVR, and ScriptPlayer.
FunGen has no mobile story — it's a desktop application. HaptiQ has a native iOS app alongside the web app, which matters more than it sounds: being able to start a generation job, watch its progress, and control a device from a phone is a genuinely different way of using this kind of tool.
Since both tools output standard .funscript files, any device your player supports will work with scripts from either generator. The difference is built-in playback: HaptiQ connects directly to devices from The Handy, Kiiroo (Keon, Pearl 2, Onyx+), Lovense (Solace Pro, Gravity, Lush, Hush, Nora, Domi, Max, Edge), OSR2+/SR6 rigs, Satisfyer Connect, WeVibe (Chorus, Sync), Svakom, and more — 872 devices indexed in total. With FunGen, device playback is a separate tool's job.
Yes, and it's a reasonable strategy. The .funscript format is the common ground: generate locally in FunGen when privacy matters most, use HaptiQ when you're away from your desktop or want the integrated editor and device playback, and keep one library of scripts that works everywhere. You can also import scripts into HaptiQ's editor to clean them up with its transform plugins regardless of where they were generated.
Yes — FunGen is free and open source. The practical cost is hardware and time: it runs on your own machine, so you need a computer capable of AI video processing, and setup and maintenance are yours to handle.
Yes. HaptiQ's 5-stage ML pipeline runs server-side, so generation speed doesn't depend on your device. Any modern browser can upload a video, watch live per-stage progress over WebSocket, and download the finished .funscript — and there's a native iOS app too.
Both output standard .funscript files, which work with players like DeoVR, HereSphere, XBVR, and ScriptPlayer, and with any funscript-compatible device. HaptiQ can additionally export multi-axis T-code across 8 axes for multi-axis rigs.
FunGen, structurally: it processes everything locally, so your videos never leave your machine. HaptiQ processes video server-side like any cloud service. If strictly local processing is a requirement, FunGen is the right choice on this dimension.
Yes. HaptiQ connects to devices via Web Bluetooth (Chrome/Edge, no extra software), Buttplug.io v3 (Intiface Central for some devices), The Handy over WiFi or cloud, and JoyHub — covering 872 indexed devices. Note that Web Bluetooth isn't available in Firefox or Safari, and The Handy's cloud mode needs an internet connection.
If the browser-based workflow sounds like your speed, you can try HaptiQ free at haptiq.app — upload a video, watch the pipeline run live, and see what it produces for your content before deciding anything.
Founding members can also lock in lifetime Pro for a one-time $99 (normally $199.99), limited to the first 100 members — details on the pricing page.
