Aimi.fm
Aimi.fm builds royalty-free music from licensed artist stems instead of scraping copyrighted recordings, then ships that engine through Aimi Sync for video scoring. Upload a clip, and Sync analyzes scenes frame by frame to compose a matching soundtrack with optional vocals, voice-over, and downloadable stems. The public homepage now teases a relaunch, but Sync pricing, docs, and the about page show the company is still shipping tools for creators and developers.
Where prompt-only generators spit out static clips, Aimi Sync treats your video as the prompt and adjusts timing per scene cut. Music comes from the Sonic Vault of human-recorded samples orchestrated by Aimi Script and the AMOS engine, with a ledger logging each stem placement for artist payouts. That sample-first model is why Aimi.fm claims over 60 patents and positions itself against tools trained on major-label catalogs.
Video creators scoring Reels, tutorials, and client work get unlimited exports on paid tiers, with a free plan for 1-minute clips. Independent musicians can upload stems to the Sonic Vault and earn from micro-usage. Developers can request the Sync API to embed scene-aware, copyright-cleared soundtracks in apps without handling licensing themselves.

Does Aimi train on copyrighted songs?
No. Aimi.fm states it does not train models on copyrighted song waveforms. Aimi Sync generates music from ethically licensed stems in the Sonic Vault, arranged in real time by Aimi Script and the AMOS engine, with usage logged in a ledger for artist payouts.
How many languages does Aimi Sync voice-over support?
Aimi.fm supports over 60 languages for AI voice-over inside Aimi Sync, with multiple voice types available. Aimi.fm can duck background music automatically when dialogue or narration is present, including voice-over added inside the Sync editor.
Can I monetize YouTube videos scored with Aimi Sync?
Aimi.fm places no restrictions on where you publish a soundtracked video from Aimi Sync, including monetized YouTube channels. The license covers audio played with that video only, not standalone use of the soundtrack or stems outside the paired video.
What stems does Aimi Sync export?
Aimi.fm exports separate WAV tracks for drums, bass, pads, keys, vocals, and FX through Aimi Sync. Pro plan users can also export per-scene stems for remixing. Stems are 48kHz stereo and licensed for use only with the video they were generated for.
