Every tool, in one place

Fourteen tools. Free, no account, nothing uploaded — every one runs inside your browser.

Pre-check your release
Free. Run, on your own device, the checks a reviewer can settle from the file and the fields — cover, master, codes, credits — and see exactly what would come back to you before you send anything.
Check loudness and true peak
Free browser loudness checker. Measure integrated LUFS, true peak and loudness range to ITU-R BS.1770-5, and see what Spotify's published normalisation will do to your master — every other service's figure is labelled as reported, not published.
◐Full mastering analysis
Free browser mastering analysis: integrated LUFS and loudness range to ITU-R BS.1770 and EBU Tech 3342, 8x oversampled true peak, PSR, spectrum, and a real codec round-trip.
Build your press kit
Bio, photo, links, credits and contacts in one file you own and host anywhere. Prints clean, works offline, and no distributor we checked offers one at all.
✎Free artist bio generator
Build a press one-liner and short, medium and long artist bios from facts you type. Nothing is invented, nothing is uploaded, no sign-up.

Every store link on one page, and you download the actual HTML file to host anywhere. No account, no tracker, and your cover never leaves your browser.

Put in your own numbers and see what each distributor really costs over five years — subscription, commission, withdrawal fees and currency spread. Every figure carries its source.
♪Tune up & keep time
Free chromatic tuner and drift-free metronome. Guitar, bass, ukulele, violin, cello and oud — Arabic and Turkish tuning. Your microphone audio never leaves the page.

✎Check your metadata
Free metadata checker for music releases. Test your artist name, title, version and featured credits against the published store style rules before you submit.
♪Find your BPM and key
Free BPM and key finder. Drop a track in and read its tempo, its musical key and its Camelot number — analysed in your browser, never uploaded.
◷When your song goes live
Free release time-zone clock. See the exact local moment your track appears in every major market, with the pitch and delivery deadlines that come before it.
▦Make a release QR code
Free QR code generator for your release link. Built in your browser, downloadable as PNG or SVG, with a contrast check so it actually scans in print.
Clean up your lyrics
Free lyrics formatter for streaming stores. Strip section labels and timestamps, fix quotes, check for explicit words and draft an LRC file.

Free ISRC and UPC/EAN validator. Check the structure of an ISRC and verify or calculate a barcode check digit instantly, in your browser.

Free browser inspector for immersive music masters. Reads the BW64 container and the ITU-R BS.2076 Audio Definition Model metadata and checks the file against the published delivery specification.
Plan your release timeline
Free release timeline planner. Enter your release date and get a dated working back-schedule from master delivery to the editorial pitch deadline and the first month after launch.
⚖Build a split sheet
Free. Write down who wrote the song and who made the recording, as two separate sheets with two separate sets of percentages, and share it through a link whose contents are never sent to our server.
◑Split royalties fairly
Royalty split calculator — fairly divide your music earnings between artists, producers, songwriters and collaborators. Instant, private, no sign-up.
◇Payout and US withholding
Free calculator. See what US tax is withheld from your music royalties by treaty country, whether you need a US tax number, and what each distributor that publishes its figures actually costs you — with the arithmetic shown.
◧Estimate streaming income
Estimate streaming income across a per-stream rate range and see what each distribution charging model costs over five years. Set every number yourself; nothing is assumed for you.
◨Build revenue scenarios
Build low, reference and high streaming revenue scenarios from your own assumptions. No fixed-rate promises, and entered values stay in your browser.
◩Plan a release budget
How to split a release marketing budget across pitching, short-form, paid media and creator work, weight it for your stage, and know when to spend nothing.
FREE TOOL · RUNS IN YOUR BROWSER

Check your master

Drop the exact file you are about to deliver. It is read in your browser — nothing is uploaded — and measured against the specifications every delivery is judged on: integrated loudness to ITU-R BS.1770-5, 8× oversampled true peak, sample rate, bit depth, clipping, DC offset, mono compatibility.

FREE TOOL · RUNS IN YOUR BROWSER

Check your artwork

Drop your cover. Dimensions, square ratio, format, transparency, colour depth and an upscaling check — plus what it actually looks like at the size most people will see it.

FREE TOOL · RUNS IN YOUR BROWSER

Check your metadata

The codes and titles that get releases sent back. Real ISRC structure validation, a real barcode check-digit calculation, and the title and artist-name rules that cause most rejections.

What it costs over five years

The first-year price is not the price. Put in your own numbers and see what each charging model actually takes from a catalogue over five years.

FREE TOOL · RUNS IN YOUR BROWSER

Estimate streaming income

Per-stream payouts are a share of a revenue pool, not a fixed price. Set the range yourself and see the spread.

FREE TOOL · RUNS IN YOUR BROWSER

Build a split sheet

Who wrote what, who owns what, agreed in writing on the day. Both columns have to total exactly 100. Export it as a CSV or print it and sign it.

FREE TOOL · RUNS IN YOUR BROWSER

Plan your release backwards

Pick the release date and every deadline before it is calculated for you — including the editorial pitching window, the one deadline that cannot be moved.

TOOLS & CALCULATORS

Plan with numbers you control

Four small planning tools. Every figure comes from your own inputs — nothing here is a quote, a rate card or a promise.

⚠

Illustrative planning tools only. Rates, dates and amounts are values you set yourself — they are not payout quotes, guarantees or delivery commitments.

Royalty & revenue estimator

Estimate gross streaming revenue from your own assumptions.

100,000
$ 0.004
You set this figure yourself. No service publishes a per-stream rate — revenue is pooled and divided by streamshare — so use an average you worked out from your own statements.

NEW
Streaming royalty calculator
Put in your streams, your blended per-stream rate and your share of the recording, and see the monthly and yearly number — plus how many streams a target income actually needs.

You have the tools. The next part is a person.

Every tool on this page is free and always will be. What they cannot do is listen to your record and decide it is worth putting behind a team. That part is an application, read by a human, and it costs nothing to send.

Apply for review

No account is created and nothing goes public. A person reads complete applications and replies by email.

Going deeper

Two engineering tools for when the basics already pass.

Mastering analysis
LUFS, loudness range, true peak, PSR, spectrum, mono behaviour and a real codec round-trip.
Immersive master inspector
Reads the BW64 container and ADM metadata and checks it against the published delivery specification.
