The basic plan includes no credits — AI paper review is billed per run, so top up by pack when you need it. Packs never expire; once credited you can rerun the review.

Notes
When does a membership make sense?
The basic plan bills monthly or yearly and can be cancelled anytime in your profile; nothing is charged after expiry. Retired legacy tiers simply run out on their own schedule.
When is a membership a good fit?
Workbench capability (compiles, storage, versions, review, API) is all included in the basic plan; AI runs on your own model key (BYOK) and is billed directly by your provider.
FAQ
FAQ
Will the trial auto-charge me?
No. Nothing is charged when the trial ends; subscribe to the basic plan to keep using the workbench.
Does the plan include AI credits?
No. The basic plan only sells workbench capability (compiles, storage, versions, review, API). Bring your own model key (BYOK) for AI — usage is billed by your provider, never by us.
I subscribed to the ¥39 plan before — what happens to me?
Nothing changes until it expires. The retired hosted-AI tier keeps its benefits for the rest of the period you already paid for and will not auto-renew afterwards; subscribe to the basic plan to continue.
Monthly or yearly — which should I pick?
Same benefits, different billing period. Yearly (¥128/yr, ≈ ¥11/mo) is cheaper than monthly (¥19/mo) if you will write long-term.
