Pricing

Public preview

Notebook Extension is currently provided as a free public preview. Billing is not active, and installing the current version does not start a subscription.

Planned plans

The following plan design is under consideration and may change before launch:

Plan	Planned features	Planned price
Free	Up to 5 additions per day, one recent existing notebook, no new-notebook creation	Free
Pro monthly	Unlimited additions, 10 recent notebooks, new-notebook creation, shortcuts	¥480 per month
Pro annual	Same planned Pro features	To be announced before launch

These limits are not yet enforced in the public-preview build. Before paid plans launch, the checkout page will disclose the final price, applicable taxes, billing period, renewal, cancellation, and refund terms. No early-user or limited-quantity offer is planned.
