Yes. Checkout asks for a card, but nothing is charged for 7 days and you get an email when the trial starts. Cancel before it ends and you pay nothing. The free trial is for new accounts, once per account.
In the app, open Options, then Account, and choose Manage subscription. It opens a secure page in your browser where you can cancel, change your card or see your receipts. You keep access until the end of the period you've paid for.
They stay right where they are: campaigns are files on your computer, and we never receive them. The app won't open without a subscription, but if you subscribe again, everything is exactly as you left it.
No. Everything at the table works without AI, including listening to the players. AI adds extras like importing from PDFs, session recaps and writing NPCs for you. For those, you can use your own Claude or ChatGPT key, or a free model that runs on your own computer with Ollama or LM Studio.
The campaign notes, maps, sessions and dice work for any tabletop game. The monster list, encounter difficulty and character sheets are made for the fifth edition of Dungeons & Dragons, using the SRD 5.2 rules.
GM Companion runs on Windows 10 and 11 for now. A Mac version is planned.
Only to sign in, to download the speech model the first time you turn on listening, and to check your subscription now and then. After a check, the app keeps working for 14 days without a connection, and a game is never interrupted.
Payments are processed by Stripe and sold through Link, Stripe's checkout service, which also handles sales tax. Your card details go to them, never to us. Your price is shown in your local currency, with tax, before you pay.
