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
Paste one webhook URL into Ko-fi, or your Streamlabs socket token. 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 one OBS source
Drop the overlay URL into OBS. The menu shows on stream, tips fire reactions, viewers see their name in the feed.
Four stream tools, one account
Reaction Menu and Throw Stuff are free forever — Pro unlocks Avatar FX and Transform.
