AI Music for Video, Built Around Your Edit
Upload your video and Musikai generates an original soundtrack shaped by its pacing, energy, and key moments.
No scrolling a stock library. No cutting a generic track until it almost fits. PostScore reads your video first, then writes music for it.
The free plan includes enough credits for about two video scores a month. No credit card required.
How PostScore Works
Upload your video
Bring an MP4 or MOV file. If you have a direction in mind, add a short note — "confident and premium, big lift at the product reveal." It is optional.
Musikai analyzes the edit
PostScore breaks the video into sections and reads its structure, energy, and emotional arc — where it builds, where it settles, where it lands.
Original music is generated
You get an original score written for this video, not a search result that was composed for someone else's project.
The score follows your video
Preview it against your footage with the music laid against the timeline, so you can hear how it tracks before you commit.
Refine it until it fits
Ask for changes and regenerate, or open the project in Musikai Studio for full control over the arrangement.
Export
Download the audio, or export your video with the score already attached.
Music Built Around Your Video, Not Cut to Fit It
A library track was written for someone else's project. Making it work on yours means trimming, looping, and hoping the chorus lands somewhere near your best moment — or recutting your video so it does. PostScore starts from the other end. It reads the edit you already made, then writes music that follows it. The result fits because it was built to fit, not because you forced it to.
Refine Everything in Musikai Studio
A generated score is a starting point, not a locked deliverable. Open any PostScore project in Musikai Studio to work with stems, trim and rearrange sections, remix, and refine the production before you export it.
Built for Ads, YouTube, Social, and Client Work
Advertising agencies and video production companies use PostScore to put a scored cut in front of a client the same day instead of next week. YouTubers and social creators use it so every video has music of its own rather than the same library track everyone else is using. Small businesses use it to make a product video sound like someone scored it on purpose.
What you can do commercially depends on your plan. The free plan is for personal, non-commercial use. Creator covers your own monetized content on platforms like YouTube, TikTok, and Instagram. Pro and Studio add paid advertising, broadcast, sync, and client work.
Why Generate Original Music Instead of Searching Stock Libraries?
Searching a library is an auditioning problem: you listen to dozens of tracks that were never made for your edit, pick the closest one, and then spend your time closing the gap between it and your video. Generating is a production step: you hand over the brief — or the video itself — and get music shaped around it. Musikai is built for the second approach. Every track is generated for your project, so it is not a track other people are also using.
