Less than a coffee a month.

No. There are no accounts. The trial starts the first time you open Slate; buying means typing your purchase email once. That's the entire "sign-up."

Slate stops accepting new writing until you subscribe — but nothing is held hostage. Your work remains on your disk as plain text — .fountain for scripts, Markdown for books — openable in any editor, and reading scripts and reviewing collaborators' proposals stay free forever.

One writer, on all the Macs you personally use — desktop and laptop, same license. Screenplays and books both, with no separate purchase for either. Cancelling is an email to support; you keep access through the year you paid for.

Not to work with you. Reading scripts and reviewing, commenting on, and merging proposed revisions is free forever. They'd only need a subscription to write their own scripts.

Yes — Slate imports .fdx, plus Fountain, plain text, and Markdown. Going the other way, you can export PDF, Fountain, a teleprompter PDF, and a shareable .slate bundle.

Yes, since version 2.0. Your library has two shelves — Scripts and Books — under the one licence, and drafts, proposed revisions, issues, comments and the beat board all work the same on either. Books are set on a 6×9″ trade page and keep a readable Markdown twin beside them. What isn't there yet: EPUB, KDP or print-shop export, running heads. Slate is where the book gets written, not where it gets printed.

Any Mac running macOS 11 or newer — Apple Silicon or Intel. Writing works fully offline — your files are on your disk. A paid license confirms itself online about once a month, with a two-week grace window if you're off-grid.

No — deliberately none. No AI writing, no AI "suggestions," no AI reading your pages, and nothing you write is ever sent to or used to train any model. Slate is a typewriter with superpowers, and what you write in it is yours alone.
