This little guy is already blinking. Give him your voice. 👆

It reacts

A character that reacts to everything you do.

Your viewers will recognise your little mascot before they recognise your username.

  • 🎤

    You talk

    Mouth moves with your voice in real time — automatically.

  • 😄

    You laugh

    Flip to your laughing frame with a single hotkey.

  • 😲

    You get surprised

    Shock face, ready on a key press.

  • 🔥

    Clutch moment

    A hype state for the plays worth remembering.

  • ❤️

    A donation lands

    Trigger a celebration exactly when it counts.

Talking is automatic from your mic. Everything else is a custom state you bind to any key.

The whole workflow

From flat PNGs to on-stream, step by step.

  1. 🎨
    STEP 1

  2. 😊
    STEP 2

    Assign expressions

    Map mouth shapes, blinks and custom states in a simple editor.

  3. 🎤
    STEP 3

    Turn on your mic

    Grant access, tune sensitivity, and the mouth starts following your voice.

  4. 🎮
    STEP 4

    Add one OBS source

    Capture the overlay window — transparent, or green-screen for any setup.

  5. 🚀
    STEP 5

    You're live

    Your character is on stream, reacting. Total time: a coffee's worth.

Everything you need

A whole VTuber-lite studio. None of the complexity.

Give your stream its own personality. No bones, no timelines, no rigging.

Follows your voice

Your character's mouth moves with you in real time. Voice-focus mode cuts background noise and keyboard clicks so only your voice moves it.

Your art, your character

Upload transparent PNGs — you only need a closed and open mouth to start. Everything else falls back gracefully.

Drops straight into OBS

A transparent, always-on-top overlay you capture as one clean window. Green-screen mode too, for any setup.

States on any hotkey

Make your own states — name them, give them art, bind any key. Laugh, rage, BRB or celebrate mid-stream.

Alive, never static

Idle float, breathing, bounce and a talking bob, with random blinks. Subtle motion that makes it feel like a little creature.

Reacts to your voice only

Voice detection and noise suppression keep the mouth moving for your speech, not fans, keyboard clicks or game audio.

Take a look inside

A clean, native desktop app.

No clutter. Everything a page or two away.

StreamSprite Editor screen

Drop in transparent PNG frames with a live preview, test buttons and a checklist of what you've added.

Included free

Comes with three characters to steal.

Start streaming the minute it opens, then make them yours or build your own from scratch.

Streamo character talking

Streamo

The friendly mint mascot. A perfect first character.

Doomer character talking

Doomer

Deadpan and lovable. Ideal for late-night runs.

Momo character talking

Momo

Bright and bouncy. Cozy-stream energy.

Made for you

If you go live, this is for you.

FAQ

Good questions.

What do I need to make a character?+

Transparent PNG frames of your character at the same canvas size. The bare minimum is a closed mouth and an open mouth; add small/medium/wide, blink and expressions for more life.

Does it work with OBS?+

Yes. Start the overlay, then add a Window Capture in OBS and pick the “StreamSprite Overlay” window. There's a transparent mode and a green-screen mode for chroma keying.

Do I need a webcam?+

No. StreamSprite is mic-driven — your voice moves the mouth. There's nothing to set up beyond choosing your microphone, and voice detection keeps it reacting to you rather than background sound.

Which computers are supported?+

macOS 13 (Ventura) or later on Apple Silicon and Intel, plus Windows 10 and 11. The Mac app is signed and notarized; the Windows version is a brand-new beta, so Windows may show a “Run anyway” prompt on first launch.

Is it really one payment?+

Yes. $20 once, no subscription. Updates are free through the app's built-in updater.

Can I sell characters I make?+

A creator marketplace is on the way — you'll be able to list and sell your sprite packs. For now, you can export characters as a single file to share or back up.
