RapCraft

RapCraft splits making a rap video into separate tools. The lyric writer drafts and edits English or Mandarin rap lyrics you can copy or download. The beat maker sketches a beat in the browser using local synthesis, not AI audio, and exports a WAV. The song generator turns lyrics into a full AI rap track. Each tool stands alone, but finished work carries forward to the next step.

The video tool gets most of the homepage. You upload a finished rap as an MP3 up to 25 MB, paste the lyrics exactly as performed, add an optional description of the look you want and choose the section to visualize. RapCraft then generates AI scenes aligned to the lyrics. It asks you to use audio you own or have permission to publish.

There's no subscription. The lyric writer is free within fair-use limits. Verified accounts get one free 30-second song preview each UTC day, and after that a single five-second watermarked scene, subject to shared daily capacity.

Paid steps are bought individually. A Rap Pack is $4.99 for three full song credits and one lyric video, a captioned lyric video up to three minutes with MP4 and SRT files is $2.99, and AI music videos are $3.99 for 15 or 30 seconds or $6.99 for 60. Saving a draft costs nothing, starting a generation reserves a credit, and a technical failure releases it automatically. A new variation because you didn't like the result uses another credit.

The site is upfront that AI scenes can change a person, object or location between shots and don't guarantee lip sync, and that the uploaded lyrics need to closely match what's sung. Its privacy page says creative inputs go to AI providers including OpenAI and fal, and that free song previews and free five-second scenes are kept for seven days.
