Text to sound effect: one sound (“a soft coin pickup”), a list of events, JSON, or a few lines about your app or game.
Each event is matched to the free CC0 library first, and nothing is made until you say so. A new sound comes as 4 takes to compare, each up to 10 seconds.
The chosen takes download as one ZIP with a sounds.json map of event to file. Claude Code, Cursor and Codex can do the same through MCP.
Every sound is CC0: free for commercial use, no attribution. Planning and library sounds are free. Making sounds: one without an account, then 3 free tries with a free account; after that, a 24-hour pass ($3.90, 50 sounds) or a plan (from $9.90 for 30 days, 50 to 200 a day). One payment, nothing renews.
