DanAI Karaoke

Browser studio that turns a song into a karaoke or music video — AI lyric sync and on-device vocal separation.

Overview

Two workspaces in one project: a Karaoke Studio for lyric recognition, timing and vocal separation, and a Video Studio for photos, background video, transitions and beat-synced visualisers — exporting 16:9 or 9:16.

The problem

Making a karaoke video usually means desktop software, manual timing line by line and uploading copyrighted audio to unknown servers.

Approach & key decisions

Media is processed on the device; audio is sent only when the user explicitly chooses AI lyric recognition.
AI lyric recognition and timing, followed by precise per-line manual correction.
In-browser vocal separation to produce an instrumental track.
Exports ASS, SRT, LRC and TXT subtitles so the timeline moves to other tools. Free, no login.
