Pricing that grows with your docs, not your readers.
Start free with one site. As you grow, each site has a flat fee and each person who writes on it adds $12 a month, or $10 when you pay yearly. Readers never cost a thing.
Gravity is now available. We set every workspace up for you, on the plan that fits. Request access and tell us your sites and editors.

How billing works
Editors are counted per site
Owners, admins and editors cost $12 a month on each site they can edit, or $10 when you pay yearly. Viewers and readers are free.
Yearly is two months free
Pay for ten months and get twelve. Pro goes from $60 to $50 per site a month, and editors from $12 to $10.
Ask AI uses your own key
You pay Anthropic or OpenAI directly, with a monthly budget per site. $25 by default.
Change plans without moving
Every plan runs on the same platform. Content and history stay put when you switch.
