How can we help you
keep writing?

Create a project, add at least one chapter in the editor, then open any tool from the AI Tools hub. Pick your project, select chapters (or let the tool choose), and hit analyze. Results save automatically to that tool's history.

Credits are slices of real AI compute, priced at true cost. Each model shows a multiplier badge — 1x is the default model; a 7x model burns credits seven times faster for the same job. Efficient models make a Student plan stretch to millions of tokens per month.

Every plan includes free monthly Co-Writer autocompletions (Free: 100 · Student: 250 · Full: 500 · Professional: unlimited). They reset each calendar month; past your allowance, completions bill as normal credits — a few credits each.

Spark conversations are deliberately billed at one-third the standard credit rate, because a writing coach only helps if you actually talk to it every day.

Yes — your words are yours. Export from the editor at any time, on every plan, including Free.

Account → Manage plan opens your Stripe billing portal, where you can upgrade, downgrade, or cancel in two clicks. Your projects are never locked.

No. Credits are only deducted after a successful response from the AI. Failed runs are logged but never billed. If you see anything odd, email us and we'll make it right.
