first, it is free. because it is work in progress.
jam and tab are in a beta test. Sign up before 23 December 2026 and everything is open until 23 December 2026, no card, because both tools are work in progress and we want your feedback more than your money right now. Below is what it costs after the test.

- Tab editor in the browser: audio next to the tab, loop, tempo
- Guitar isolation and suggestions with a confidence
- Play parts in yourself through an audio interface
- Guitar Pro 5 in and out, MusicXML out
- Stem separation: 7 songs a month, fair use
- Includes amp, the native Windows audio engine

Students play, you create.
A plan for guitar teachers is in the works: you prepare the exercise in tab, students practise with play and jam, takes come back to you with the hard bars marked. No price yet, and no date we would put on a page before it holds. Sign up and we will tell you when it is ready.
- jam on Windows: works, being finished first, beta test.
- tab in the browser: works, work in progress, beta test.
- One account for everything at account.strummr.ai.
- jam's tabs: measured on one guitar and one player so far; some notes will be wrong, and you fix them.
- tab: printing, repeats and triplets missing; candidates wrong about half the time on unseen songs.
- Mac: no build, no date.

the details
Why is it free until 23 December?
Because it is a beta test of two tools that are work in progress. Create an account before 23 December 2026 and both are open until then. No card, no automatic charge afterwards. When the test ends you pick a plan, or you do not, and your account stays yours either way. What we want from you until then is feedback.
Yearly or monthly?
Yearly is the standard, and it is what we open with. Monthly billing follows after launch at the prices shown; tab on its own is yearly only. After the first year you can cancel monthly, as German law requires. No price increase in the first year for anyone who signed up early.
What does fair use mean?
We do not run counters against you. Stem separation in tab runs on our GPU, so we name a limit, 7 songs a month, and trust you with it. If someone pushes far beyond it, we get in touch before anything else happens.
Is amp a separate purchase?
No. amp is the native Windows audio engine under tab's play-it-in recording and under jam. It comes with either plan and plays your own NAM captures. It is not sold on its own.
Who handles payment?
Checkout, invoices and VAT go through Paddle as merchant of record. Card and PayPal. Prices are shown including VAT; the US price is the same number in dollars.
Can I get my money back?
EU consumers have a 14-day right of withdrawal, as set out in the AGB. If a tool does not do for you what this page says it does, write to us; we would rather fix the page or the tool than keep the money.
What about my recordings?
jam keeps your dry guitar signal on your machine. Only what you export leaves it. tab uploads the song you are working on for guitar isolation; there is no archive and no sharing on our side.
Why not a one-time purchase?
Because guitar isolation costs GPU time every month, and because jam's precise pass will too once it ships. A yearly price keeps that honest. If you only need one song, the trial is the time to do it.
one account. both tools. free while we finish them.
Sign up once for jam and tab. Everything is open until 23 December 2026, then you decide what is worth keeping. Tell us what to fix first.
