Everything they need to come alive
Your sidecaster gets a look, a personality, a voice, and the smarts to know when to speak up and when to hang back.
Custom Avatar
Describe your character and AI generates a full sprite sheet — six expressions, consistent style. Or upload your own art.
Personality & Voice
Write their personality, set their voice. Your sidecaster sounds and acts exactly how you want — witty, chill, chaotic, whatever.
Twitch Integration
They read chat, react to follows, subs, and raids. They know when to chime in and when to stay quiet.
Smart Timing
Real-time mic detection means they never talk over you. They wait for a natural pause, then jump in.
Beta testers
Streamers are already going live with their sidecasters
My chat went wild when my sidecaster started roasting me. Best stream I've had in months.
I made a pirate parrot sidecaster and they react to every raid with cannon sounds. The viewers love them.
Finally something that doesn't just read chat messages in a robot voice. They actually have personality.
