Stream Hearts

Your chat. Your stage.

Bring your community into the action, spend time together and prepare your next stream. Stream Hearts combines fan characters, chat games and broadcasting tools in one Windows app. Add a single browser source to your broadcasting software and every feature appears on the same scene.

Play together

Cheek Beat, Roll the Ball races and Rumbling Expedition, Pinball Race, Dalgona, Number Baseball, Pizza Roulette, Carrot Harvest, Chat Ladder, Gomoku, Reversi and Knight Chess, and a Custom Board where dice open missions. Viewers join through chat commands and votes, and some games put the broadcaster in control.

Build a shared stage

When viewers chat, their fan characters appear on stage with name tags and speech bubbles. Hang out in the fan playground and Squishy Fans, run the fan restaurant, late-night food stall and star shard mine together, and end the stream by launching farewells as chat fireworks. Match your broadcast with your own pixel SD model and stage decorations.

Stage events

RPG mode with bosses and monsters, troublemakers that crash the stage, 60+ reaction effects triggered by donations, chat, points or hotkeys, and a claw machine that picks up fan characters. The broadcaster decides what is enabled and what triggers it.

Prepare and run your stream

Timers and clocks, schedules, notes, calendar, chat polls and chat topics, Drawing Helper, replay thumbnail maker, recording, editing and GIF making, image slides, stingers and standby screens, background music and audio effects, capture studio, visual novel maker, picture diary, mind map and stream ledger—all in one app.

Manage participation records and free points

Track chat-based participation time, missions and free points, view balances, and manage records and backups. Broadcasters can manually add or deduct points. Chat polls do not deduct points. Point purchasing, cash redemption and transfers are not provided.

Connect your broadcast scene

Display the app's output using a browser-source address in your broadcasting software. Online chat connections require internet access and account authorization for a supported platform. Broadcasting software is a separate installation, and chat and output may be delayed depending on your setup.

Supported streaming platforms: CHZZK, YouTube, Twitch, and SOOP.
Available features may vary by platform.
