Managed AI, right inside Writer Studio

Writer Studio is free, offline, and yours — the manuscript lives on your machine and the app never needs the cloud just to let you write. Authr AI is managed AI for the moments you want a second pair of hands: turn it on and a capable assistant works right inside the app, with no API key of your own and no separate provider signup. Authr AI is not sold on its own — it is the AI part of the Authr Plus subscription.

What Authr AI does

Authr AI is an assistant, not a ghostwriter. It can read your whole book, check a passage for problems, track a character or a plot thread, and answer questions about your story. Because it works through the app, it can also do what you can do — update metadata, add a character to the Book Wiki, jump you to the right scene — all through chat. It is off by default, and every change it proposes waits for your confirmation, so it never quietly rewrites your canon.

Why managed

Running your own AI means an API key, a provider account, and a bill you assemble yourself — worth it if you want to choose the provider or keep everything local. That path is free and stays free. Authr AI removes the plumbing: our key, one bill, and the AI is simply there inside Writer Studio. No keys to paste, no provider to sign up with, nothing to configure.

Authr AI is part of Authr Plus

Authr Plus provides two services:

• Authr AI — managed AI, with no key of your own.
• Cloud backup — a complete copy of a project on Authr's server.

Plans differ only by the monthly AI budget. The product shows only the fraction used, because request and token counts vary by model and workload.

The plans, their prices, and everything the subscription covers are on the Authr Plus page.

What is always free

You never need a subscription to write a book and finish it:

• Everything local — writing, structure, the Book Wiki, search, export, local backups, and version history.
• AI on your own key, across as many books as you write.
• Unlimited publications and full reader analytics, including unique readers, completion, progress, time, and drop-off.

If a subscription lapses, Authr AI stops. Nothing local changes, publications keep serving readers, reader analytics stay available, and AI on your own key works exactly as before.
