Questions

What counts as an agent task?

One job for an agent, like beta-reading a chapter or line-editing a scene. Quick brainstorm replies use far less.

Does my own Claude or ChatGPT count?

No. AI you connect yourself runs on your own subscription, so it's unlimited on every plan.

What if I run out?

In-app agents pause until next month or until you upgrade. Your writing is never blocked.

Is there a free trial?

The Free plan is the trial. Every feature, no time limit.

Can I cancel any time?

Yes. Changes take effect at the end of the period you've paid for, and your books stay yours.

Do prices include tax?

Prices are in US dollars. Tax is added at checkout where it applies.
