STREAMALTER · LIVE CARTOON FOR STREAMERS

Stream as whatever character you can dream up!

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.

Signups are limited to 150 a day at the moment.

EXAMPLES

Your character. Your studio. Infinite combinations.

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

A cartoon that's actually you, not a mask over you.

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

Your eyes and mouth, cut out live.

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.

REAL EXPRESSIONSLOCKED TO THE CHARACTER

02 · STRETCH

Planted base. Elastic top.

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

Describe a character. Wear it.

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

A fluffy little sheep, out of the box.

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

OBS browser source or desktop overlay.

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.

QUESTIONS

Before you go live.

What do I need?

A webcam and a current desktop browser. For streaming, OBS (or anything that takes a browser source), or the desktop overlay app.

Is my camera feed uploaded?

No. Face tracking and the eye and mouth cutouts happen in your browser. Your account stores your settings, not your video.

Which character do I get?

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.

How do I cancel?

Open ACCOUNT on this site and choose Manage billing. Cancelling stops the next charge; you keep access until the end of the period you paid for.

Questions? Say hello.

Billing, bugs, a takedown request, or just an idea. Send it here and a real person will answer by email.
