Put the final gloss on your AI-made song.
That AI-generated track is good — but 2% off. Smeared highs, boxy lows, vocals that don't quite sit. Gloss polishes it automatically: drop in a file and go from diagnosis to finished master in one pass.

Same song, same section, loudness-matched — what changes is the texture, not the volume. Toggle Original↔Gloss while it plays.
Good song.
Not quite finished.
Put an AI-generated track next to a commercial release and certain things stand out. The song isn't bad — most of the time it just hasn't been finished.
The sparkle in the highs got lost somewhere — next to commercial tracks it sounds oddly congested.
Pitch-perfect but strangely hard to love. A voice that feels pasted on top of the track.
One band rings through the whole song — a minute in, your ears give up before you do.

Frequently asked
Does it work on songs I recorded myself, not just AI?
Yes — tracks from any generative-AI tool, and your own recorded demos too. That said, the engine specializes in typical AI-generation artifacts (smeared highs, sustained resonances, pasted-on vocals), so the effect is biggest on AI tracks.
How is this different from a mastering service?
Two ways. ① Regular mastering targets level and tone; Gloss targets the fatigue artifacts of AI-generated audio. ② Your song is never sent to a server — everything runs on your computer.
Is the watermark really the only limit of the free version?
Yes. No feature, track-count, or duration limits. You get one audio-watermark-free MP3 per day; other exports just carry a short, periodic 'Gloss' voice tag (audio watermark). Listen as much as you want — subscribe when you're ready to release.
Can I cancel anytime?
Yes. The subscription auto-renews and you can cancel anytime; Pro stays active until the end of the period you've paid for, and after that the app keeps working as the free version. Payments and refunds are handled through Lemon Squeezy.
Do I need any music knowledge?
That's the whole point. It's one-click auto by default, and diagnostics come in plain words like "sounds muffled — try Sparkle at 30%." Every control has built-in help.
