Unchained tools

Free browser tools for musicians

The fiddly jobs around every release, done in seconds: check your artwork before a store rejects it, work out your timeline, settle your splits, find the IDs that forms keep asking for.

Artwork

Album artwork checker

Drop in your cover art and catch the rejections before the stores do: size, format, colour mode and more.

Release planning

Release date calculator

Pick a release date and get the full timeline worked backwards: upload, pitch, presave and promo milestones.

Splits and money

Split sheet generator

Record who wrote what, get a clean signable sheet, and save it as a PDF before the money exists.

Splits and money

Music split calculator

Split any payment between collaborators by percentages or parts, with cent-exact payouts that always add up.

Identifiers

Apple Music artist ID finder

Search an artist or paste any Apple Music link and get the numeric ID that claim flows and distributors ask for.

Audio

Audio file checker

Drop in your master and catch the rejections before a store does: format, sample rate, clipping, silence and more.

Audio

LUFS meter

Measure loudness the way platforms do: integrated LUFS, true peak and what normalisation will do to your master.

Audio

BPM and key finder

Tempo and musical key with Camelot notation for DJs, and honest confidence when a track resists a single answer.

Practice

Online metronome

Tap tempo, time signatures, subdivisions, swing, a speed trainer and silent bars, with sample-accurate timing.

Promotion

Audiogram maker

Turn a track and its cover art into an animated clip for stories and reels. No watermark, no upload, no caps.

Promotion

Release announcement card maker

Announcement graphics for stories, the feed, link previews and thumbnails, in colours pulled from your cover art.

Built to actually help

Every release comes with a trail of small, sharp problems: artwork bounced for a reason the store never explains, a pitch deadline missed because nobody counted backwards, a split that does not add up, a form demanding an ID nobody knows how to find. Each tool here takes one of those problems and finishes it in under a minute.

There is no catch to look for. No account, no email gate, no trial mechanics, and nothing to install: everything runs right in your browser, so there is no upload step and nothing we store. They are free because we would rather you meet us through something useful.

Common questions

Are these tools really free?

Yes. Free to use, no account, no trial mechanics. They are utilities we build for artists and labels preparing releases.

Do my files or details get uploaded?

No. Processing happens in your browser. Artwork, names, amounts and dates never reach our servers, and nothing persists when you close the page.

Do I need an Unchained account?

No. Every tool works without one. If a tool leads naturally into a feature of ours, the handoff is a link, not a wall.

Will there be more tools?

Yes, this set grows. New tools land on this page as they ship, and the set leans toward the checks and calculations that come up around every release.

The tools handle the small stuff. We handle the release.

Unchained delivers your music to 150+ platforms with royalty splits, playlist pitching and real support behind every release.
