Tailor your music to suit specific moods or themes by setting a prompt for the AI, and watch as it crafts a unique piece that perfectly complements your sound.
This user-friendly platform is perfect for musicians, producers, and creators eager to push the boundaries of their artistry. Start by uploading a file and selecting a 10-second context from your music. Enter a filename to keep track of your creations, write a prompt to direct the AI, and choose how many seconds you want your audio extended.
AI generates your audio extension, seamlessly continuing from where your original context ends. AI firsthand. AI!
Aimi.fm

What is 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.
