Viewers tip.
Your avatar reacts live.
Put a priced reaction menu on your stream. A viewer tips through your own Ko-fi, Streamlabs, Gank or StreamElements — YouTube Jewels and Twitch Bits too — and your VTube Studio model reacts instantly in OBS.

The real Throw Stuff overlay, recorded as-is (stand-in model) — on your stream the object hits your own VTube Studio avatar.
Connect your tips
Click Connect Streamlabs in your dashboard, or paste one webhook URL into Ko-fi. Your payout setup doesn't change at all.
Map reactions
Connect VTube Studio once and pick which hotkey each price fires — surprised, blush, panic, costume swap, anything your model can do.
Add it to OBS
Drop the overlay URL into OBS as a browser source — one for each tool you use. The menu shows on stream, tips fire reactions, viewers see their name in the feed.
Nine stream tools, one account
Reaction Menu and Throw Stuff are free forever — Pro adds seven VTube Studio effects that move your real model.
Reaction Menu
Viewers tip → your VTube Studio avatar reacts live in OBS. Free: 2 priced reactions.
Throw Stuff
Viewers tip → an object flies across your OBS and splats on your avatar. No VTS needed.
Avatar FX
Donations tint, grow, shrink or spin your VTube Studio avatar — a real effect on the model.
Model Swap
A tip switches you to another VTube Studio model for a while — pick it straight from your VTS list — then your main model comes back to the same spot.
Physics Burst
A tip shakes your VTube Studio model — hair, clothes and accessories bounce and blow in a gust.
Param Pulse
A tip drives a VTube Studio parameter — a smile, an open mouth, a rigged blush — for a few seconds.
Pin Props
A tip drops a prop onto your avatar — a heart, a crown, a hat (your own PNGs in VTS) — that rides along with the model, then fades away.
Screen FX
A tip switches VTube Studio to a look you built in its post-processing — bloom, glitch, sepia — then fades back.
Outfit Swap
A tip takes your body off and puts on an outfit you arranged in VTS, every item exactly where you placed it — then changes you back.
