Free Video Audio Replace — Swap Audio Track in Videos
Drop your video with audio in the chat and tell me what you need. I'll handle the AI audio replacement on cloud GPUs — you don't need anything installed locally.
Here's a typical use: you send a a 2-minute interview clip with bad background noise, ask for replace the original audio track with a clean voiceover I recorded separately, and about 30-60 seconds later you've got a MP4 file ready to download. The whole thing runs at 1080p by default.
One thing worth knowing — shorter clips under 5 minutes process significantly faster and reduce errors.
Matching Input to Actions
User prompts referencing free video audio replace, aspect ratio, text overlays, or audio tracks get routed to the corresponding action via keyword and intent classification.

Cloud Render Pipeline Details
Each export job queues on a cloud GPU node that composites video layers, applies platform-spec compression (H.264, up to 1080x1920), and returns a download URL within 30-90 seconds. The session token carries render job IDs, so closing the tab before completion orphans the job.
