Beatomat is a DJ app in a browser tab with two ways to play: an AI DJ that mixes for you, and two decks to mix yourself.

AI DJ

Press Just play and it picks every next record by tempo and key, then mixes it in. About 1 in 5 changes is a long blend, where two records that fit play together for a long stretch while the bass passes from one to the other; the rest are short or bridged with drums. The screen tells you how long each mix will run and why.

Decks

Two decks with a 3-band EQ (bass, mids, highs), Sync to line up the beats, loops, hot cues (marked spots you can jump back to) and effects, plus a guided first mix in five short steps. You can switch from the AI DJ to the decks without the music stopping. It doesn't play your own files, connect to a MIDI controller or record your set.

Music included

About 6,800 tracks from independent artists on Audius, every one credited, are ready to mix. About 9,000 well-known records from YouTube play too, with a short fade instead of a mix.

Price

Listening needs no account and nothing to install, and it works on a phone. Mixing is free for 30 minutes a day; after that the music keeps playing, with short fades.
