Payment Issues Q&A

1. Plans & Limits

How much is the limit for a paid account?

Current plans (Lite / Pro / Max) — see ::

Plans come with a fixed amount of monthly credits plus an included Cloud Computer. Credits are a single unified pool (no longer split into Basic / Advanced / Elite) and are consumed dynamically based on token usage.

Exact credit amounts and feature details are shown on the pricing page.

Legacy plans (Plus / Unlimited / Professional / Basic / Starter / Pocket, no longer on sale):

Plus / Unlimited: unlimited Basic credits; Advanced credits capped at 1,500 per month (once exceeded, some advanced features are restricted and high-end models may be downgraded); Elite credits are separate.

Professional / Basic / Starter: legacy monthly plans with the old three-tier credit system.

Pocket: a mobile-exclusive special offer. It can only be used on mobile devices (iOS / Android app) — it is not available on other platforms (browser extension, web, or desktop apps).

Legacy plans keep working until cancelled; their credit rules remain unchanged. Once cancelled, a legacy plan cannot be restored.

Booster Packs (extra credits):

New plans: Booster Packs are available as a one-time purchase with any paid plan. Extra credits never expire and are only used after your monthly credits run out.

Legacy plans: a legacy Booster Pack (one-time purchase of extra Advanced credits) is also available for active legacy plans.

How are charges calculated for upgrading a package?

You can upgrade directly on the pricing page: click the button of the plan you want to upgrade to, and a dialog will pop up showing the exact amount you need to pay — the price difference, after your current plan's remaining value is deducted. You can close the dialog to cancel, or click Confirm to complete the upgrade purchase.

Your legacy credits do not carry over — after the upgrade, all credits on your account are the new plan's credits.
