STREAMALTER · LIVE CARTOON FOR STREAMERS
StreamAlter cuts your real eyes and mouth out of your webcam, live, and puts them on a cartoon character that stretches, turns and tilts with your head. Start with our fluffy little sheep — or type a sentence, like “a sleepy moon with a nightcap,” and the character creator builds you a new one.

EXAMPLES
These are examples of what you can stream as — not the only options. Every character and backdrop here was made with the character and studio creators. Every character rides the same live rig, and your own eyes and mouth go on top.

FEATURES
Face tracking runs in your browser and drives everything you see: where the character leans, which way it turns, how far it stretches. The face itself is never redrawn — it's yours.
01 · LIVE FACE GRAFTS
StreamAlter lifts your eyes and mouth straight out of the webcam video and locks them onto the character. No avatar guessing at your expression — viewers see the real thing, on a body that isn't.
02 · STRETCH
The character stays rooted to the ground while its top stretches and leans to follow you around the frame — lean in and it reaches.
03 · CHARACTER CREATOR BETA
Type a sentence — a melting candle in a wizard hat, a grumpy cactus in sunglasses — pick a style, and StreamAlter generates it with AI, cuts out the background, and rigs it to your face. Your real eyes and mouth go on top.

04 · READY ON DAY ONE
Every account starts with a default character, so you can go live the minute you sign in — then swap to something you made whenever you like.
05 · GOES WHERE YOU STREAM
Paste your private broadcast link into OBS as a browser source, or run the desktop overlay app to float the character over anything on screen. The overlay goes click-through on its own when your mouse leaves, so it never eats your clicks.
06 · YOUR SETUP, SAVED
Your settings save to your account and load wherever you open StreamAlter — the browser tab, your OBS browser source, or the desktop overlay.
HOW IT WORKS
No password. We email you a link that signs you straight in and creates your account if it's new.
One plan, $9.99 a month through Stripe checkout. Cancel from your account panel whenever you like.
Allow your camera, hit GO LIVE, then add your broadcast link to OBS or launch the desktop overlay.
PRICING
No tiers, no add-ons. The membership unlocks StreamAlter in your browser, your OBS broadcast link, the desktop overlay, and the character creator beta.
STREAMALTER MEMBERSHIP
Billed monthly by Stripe. Cancel anytime from the account panel; access runs to the end of the billing period. No refunds. StreamAlter is beta software provided as-is — see the terms.
DONATE

A webcam and a current desktop browser. For streaming, OBS (or anything that takes a browser source), or the desktop overlay app.
No. Face tracking and the eye and mouth cutouts happen in your browser. Your account stores your settings, not your video.
Everyone starts with a fluffy little sheep. With the character creator (beta) you can describe your own in a sentence and wear that instead. Beta tries are limited while we test it.
