Plans and quota

Three plans. Anonymous needs nothing, Free needs a Google sign-in, Pro is a subscription. Current prices are on the pricing page; the limits below come from the code.

Two meters, not one

A rewrite spends a request and input tokens, and you can run out of either.

The token meter is charged the whole prompt, not just your draft. The instructions alone are around 1,400 tokens before you have written a word. That is why the token allowance looks large next to the request count: on Free, 40 requests at roughly 1,400 tokens of overhead each is most of a 200,000 budget before any drafts are counted.

Practically: short drafts run out of requests first, long ones run out of tokens first.

There is also a fair-use ceiling on what an account's usage costs to serve, shared by rewrites, the writing agent and the help assistant. It is sized so that every rewrite a plan advertises fits under it; you only meet it with unusually long or generative work, and a signed-in account continues on credits when you do.

Periods

Anonymous is a one-time trial and never resets — an account is the way past it. Free and Pro reset monthly. resetAt on a 402 and on GET /api/usage tells you exactly when; it is absent when the allowance does not reset.

Credits

When the included allowance is gone, a signed-in account can keep going on credits bought in one-time lots. Packs start at $2 for about 20 rewrites of a 1,000-word draft; see pricing. Credits never expire.

• Included quota is always spent first. Credits are the fallback, never the default.
• The usage event on a rewrite stream says which paid, via fundingSource: included or wallet.
• API keys spend the owning user's wallet. There is no per-key balance.
• Credits are reserved when a rewrite starts and settled when it finishes, so a request in flight shows in reservedCredits.

Model tiers

standard is the default and the only tier below Pro. Pro adds fast — quicker, cheaper, slightly less careful — and auto, which picks. There is no tier that changes the rules about facts.
