A Video You Have

Create a free account with 20 sign-up credits and no card; a run costs 1 credit and a free account gets 1 audio run in total before it needs a pack (credit packs start at $2.99). The result carries a "Made with AI" label.
For clips that just need a mood, fast
Add a track without leaving your clip
The instrumental is generated, then mixed under your video in one pass.
Works with any clip
Upload the video you already recorded or generated elsewhere.
Genre-based instrumental
Describe a genre or mood, no track library to search through.
Auto-matched length
The track is generated to match your clip, so it runs the full length.
Mixed under your audio
The track sits as a bed under your clip's own sound, not a hard swap, and the result carries a "Made with AI" label.
Blocks named real artists
A request naming a real performer or artist is blocked before generation.
Packs, credits never expire
Pay per credit, per run. Nothing expires.
How do I add music to a video I already have with AI?
Follow these steps in the app.
Upload your video
Add the clip you already recorded or generated elsewhere.
Describe a genre or mood

Download the mixed clip
The original stays in your library and the new file carries a "Made with AI" label.

CapCut alternative for adding background music to a video
CapCut and Inflyu both add music to a video you already have. CapCut's page says to add music online for free, states that no credit card is required, and lists Pro at USD 14 a month. Inflyu does it differently: you describe a genre or mood, Inflyu generates a new instrumental to match the clip and mixes it under your own audio, so there is no library to search and no named-artist track. Choose CapCut when you want to pick or trim a specific song inside an editor. Choose Inflyu when you want a generated bed in one step, on 20 sign-up credits.

How good is AI-generated music on my video, and what are the limits?
The track is a new instrumental matched to your clip's length and mixed quietly under its own audio, so it works as a mood bed rather than a featured song. Limits: no vocals, no named artists, a "Made with AI" label on the result, and 1 audio run in total on a free account. Clips with little existing music work best.
Limits today
- Instrumental only: there are no vocals. For a sung performance, Inflyu has a separate Sing It tool.
- Named artists: a request that names a real performer or artist is blocked before generation.
- Mix: the track is a quiet bed under your clip's own audio, not a hard swap, and the result carries a "Made with AI" label.
- Taste: a generated track is a draft of a mood; the result depends on the genre words you give it.
- Free accounts: 1 audio run in total, then a credit pack.
What works best
- Clips with little or no background music, such as talking-head, product or vlog footage, take a bed best.
- Use a genre plus a mood ("calm lo-fi", "tense cinematic") rather than a song title.
- If your clip is mostly silent, the music will be the main sound; for effects, add sound as a separate step.
- Listen to the first run before you repeat it with new words.
