Make anything talk like a video game.

Type a line, pick a character, hear them say it. Then save it as a video for Reels, TikTok, Shorts or YouTube. It all happens on your device, works offline, and it’s free and open source.

Characters

Lines

Start from a scene
Delivery

Tap a delivery to add it to the line you’re on, or type it in brackets: (slow, awed), (very fast and very high). Punctuation does the rest: a question goes up, a dash cuts off, capitals are louder. WIZARD: Hello puts a name on one line. Ctrl Enter plays the line you’re typing; outside the box, Space plays and ← → step through the lines.
