Midi AI is a web-based tool that uses AI to generate MIDI files from text descriptions. You describe what you want — a chord progression, melody, or beat — and the AI creates a downloadable .mid file you can drag into your DAW.
You can generate chord progressions, melodies, basslines, drum patterns, and full arrangements. Specify a key, scale, tempo, and style, and the AI builds a MIDI file to match.
All generated files are standard .mid (MIDI) format. They work with any DAW — Ableton, FL Studio, Logic Pro, GarageBand, Reaper, and others.
Yes. A free account is required to generate and save MIDI files. Signing up takes about 10 seconds with email or Google login.
You get 10,000 free tokens when you sign up — enough for a couple of generations. After that, plans start at $5/month for 300K tokens (Hobby). The Pro plan is $25/month for 1.2M tokens, and Studio is $75/month for 4.5M tokens. You can also use your own OpenAI API key instead of a subscription.
Tokens are the currency for AI generations. Each generation uses tokens based on complexity. Plans range from 300K tokens/month (Hobby, $5) to 4.5M tokens/month (Studio, $75). Tokens reset each billing cycle.
Yes. You can add your own OpenAI API key in account settings. This gives you unlimited generations without a subscription — you just pay OpenAI directly for usage.
Yes. You own full rights to every MIDI file you generate. Use them in songs, beats, film scores, games, or any other project — no attribution required.
The sample library is a collection of 1,000+ pre-made MIDI files organized by genre — jazz, lo-fi, trap, EDM, cinematic, and more. You can preview and download them directly from the site.
Yes. Midi AI includes a built-in piano roll editor where you can move, add, or delete notes. You can also use the AI chat to describe changes like "make it more jazzy" or "transpose up 3 semitones."
Midi AI uses OpenAI's GPT models with custom prompts trained for MIDI music generation. The AI understands music theory concepts like keys, scales, chord voicings, and rhythmic patterns.
Yes. Upload any .mid file and Midi AI will analyze the notes to detect the most likely key and scale. This is useful for matching new parts to existing tracks.
