One run is one studio session: the wand reads the track, the studio opens, and the kit it writes lands in the crate.

Do you keep my music or my words?

Your track never uploads; it is measured on your device and stays there. Your kits are yours to keep, export, and delete.

Anytime. Monthly or annual, you keep access through the period you already paid for. No retention call, no dark pattern.

What if I need more than 25 runs in a month?

Move to Pro for 150 runs a month, or buy runs by the piece at $1 each, flat. Past any plan's ceiling runs simply cost $1, so you are never blocked mid-release.

Can I buy runs without a subscription?

Yes, and for most artists it is the better fit. Runs by the piece: $1 a run, flat. They sit in your account until you need them, with no renewal and nothing to cancel.

Is the free plan really free?

Yes. No card to start. Reading a track is free and unlimited forever because it happens in your browser, and you get 10 full kits to see exactly what Thermal writes before you decide to pay.

What does it cost to read a track?

Nothing, ever. Tempo, key, dynamics, loudness and the energy arc are measured on your own device, so there is no counter on it and the audio never reaches a server. You only spend a run when you ask Thermal to write something.

Annual saves $24 a year on Solo, $60 on Pro

Free, unlimited, no account

Every measurement, as many as you like

Drop a track and the wand reads it: tempo, key, dynamics, loudness, the shape of its energy. That read happens in your browser, so the audio never reaches a server, and there is no counter on it now or later. The same goes for the hype strip: paste any bio and see what comes out. You only start spending when you ask the studio to write something.

The usual way to pay

Runs by the piece

Most artists release four or five times a year, not four or five times a month, and a subscription is the wrong shape for that. A run costs $1, flat. Buy what a release needs, they sit in your account until you use them, and nothing renews or expires while your account lives. A whole launch usually costs less than lunch.

If you release often enough that a month is the right unit, the plans below cost less per run and keep your whole catalog open.

Early access pricing, and it can still shift. Every plan starts on the free tier, so you read the work before you pay. Cut is invite-only. Thermal does not publish a Cut price.

The comparison

Three ways to write the words around a release. Here is what each one actually costs you.

Comparison of a publicist, a fill-in template, and Thermal across cost, honesty, and what you get.
	A publicist	A fill-in template	Thermal
Cost	Hundreds a release, sometimes a monthly retainer.	Cheap or free, then paid for in your own hours.	$0 to start. $8 a month on annual, $10 month to month.
Honesty	Polished, and often quietly inflated.	Blank fields you fill with your own hype.	Strips the hype, keeps what is true.
What you get	A bio, on their timeline, not yours.	One empty format, still to be written.	Signature, positioning, kit, campaign. Yours to send.

What counts as a run

One run is one studio session. Not one bio, not one caption. The wand, the kit, and the crate, in one pass.

01

You drop the track

A file, a link, a few notes if you have them. The wand reads it here.Sample brief: solo artist, debut EP, cut live to tape in a converted horse trailer outside Tucson.

02

The studio opens

It takes a reading, strips the hype anyone could write, and finds the real line.That brief read 96 BPM, with 5 phrases of hype cut.

03

The kit lands in the crate

Bios, EPK, press release, pitches, social, brand, campaign desk. That whole pass is one run.
