Authr AI: the assistant without your own key

The AI assistant in Writer Studio works without a subscription, with your own API key from an AI service or with a local model. But you have to get that key yourself: sign up with the service and keep an eye on your balance.

Authr AI skips all of that. Sign in to your authr.app account with the Account button, open File → Settings... → AI, and turn on Enable AI. Authr AI is already selected there.

Cloud backup

Writer Studio already makes backups, but it keeps them on your computer. If the computer breaks or gets stolen, the backups go with it. With Authr Plus, a backup of the project is also kept on our server, so you can restore the book on a new computer.

Cloud backup is off until you turn it on, project by project. A backup uploads when you create one by hand, and from time to time when you close the project or the app. The server keeps the last few backups and deletes older ones.

Cloud backup does not sync your edits between computers. Before you switch computers, create a backup by hand and wait for the upload; otherwise the other computer restores an older version. The cloud backup guide walks through each step.

The Authr AI budget

Writer Studio settings and the Subscription page on authr.app show how much of the monthly budget you have used, as a percentage. There is no fixed number of requests: analyzing a whole chapter costs more than answering a short question.

Free without a subscription

Without paying anything, you can start a book, finish it, and hand it to readers:

  • Write and edit the book, build its structure, and keep the Book Wiki.
  • Search, check the text, and export the book.
  • Make backups on your computer and go back to earlier versions.
  • Use the AI assistant with your own API key or a local model.
  • Send the book or a single chapter to beta readers and see reading analytics, with no limits.

If your subscription ends

Authr AI turns off, and new backups stop uploading. Backups already on the server stay: you can restore a project from them or delete the ones you don't need.

Everything else stays as it was: your books, the backups on your computer, publications, and reading analytics.

Frequently asked questions

Do I need an account?
Not to write. You need an authr.app account for the subscription and to send a book to beta readers.
What happens if I use up the AI budget before the month ends?
Authr AI stops answering, and you see a message that the monthly budget is used up. The budget renews with each monthly payment of your subscription: the month runs from one payment to the next, not by the calendar. If you don't want to wait, move to a plan with a bigger budget on the Subscription page of authr.app, or connect your own API key for a while.
How is cloud backup protected?
Backups are encrypted in transit and at rest on our server. The encryption key is kept on the server too. That is why signing in is enough on a new computer, with no separate password, and it also means the server administrator can open a backup.

Plans

Writer Studio is free: you can write, publish on authr.app, and see reader statistics without a subscription. Authr Plus covers only two things, both of which run on our servers: Authr AI and cloud backup of your projects.

Every plan includes the same things. The only difference is how much Authr AI you can use each month.

Prices exclude tax. Your country's tax is added at checkout.

Paddle, our payment provider, can't take payments from some countries, including Russia and Belarus. If you can't pay, write to support.
