Questions
Is Beatomat free?
Yes. The music keeps playing for as long as you like: the AI DJ and every mix play without an account. On Free, Beatomat mixes like a DJ for your first 30 minutes a day, finished mixes included, then records change with a short fade instead of a long DJ blend. Unlimited keeps the long DJ blends going all day, and until 20 December it is free for 6 months for the first 200 founding members: the seat is instant.
Do I need to install anything?
No. Beatomat runs in any modern browser on a laptop or phone. Nothing to download, no plugin.
How does the AI DJ choose the next track?
It looks at the record on air and only considers records close enough in tempo to beat-match (within 4%) and in a compatible key. Out of that shortlist it orders what comes next. Because the shortlist is already safe, anything it picks will blend.
Can I mix my own music?
Not yet. The decks play the crate: records by artists who publish on Audius and the Internet Archive, and records everybody knows, from YouTube.
What is a key-matched blend?
Every song is in a musical key. Two songs in the same or neighbouring keys can play over each other without sounding wrong, so the AI DJ holds those together for a long blend. Clashing pairs get a short cut or a drum bridge instead.
What are the decks?
Two decks and a mixer in the browser: a three-band EQ, hot cues, loops and effects, over the same crate. Every record shows its tempo and key, so you can see what will blend before you try it. Hand the set back to the AI DJ at any moment.
