Independent, source-linked guidance · Updated July 30, 2026
AI subscriptions do not all measure usage the same way. One service may use a rolling message window, another may show a weekly percentage pool, and another may sell credits only after an included allowance is exhausted. This hub helps you identify which limit you are looking at, where to check it, and whether waiting, troubleshooting, buying extra usage, or changing plans is the sensible next step.
Start with the product’s own usage or billing screen whenever possible. Limits can depend on the plan, model, feature, account, region, rollout, and amount of computation required. A number quoted for one user should not be treated as a universal allowance.
Quick comparison
| Product | What users commonly see | Best first check | What to do at the limit |
|---|---|---|---|
| ChatGPT | Plan allowances plus optional credits for supported agentic features | Codex Settings → Usage Dashboard, or the relevant workspace billing page | Wait for included usage to reset, add credits when eligible, or compare plans |
| Claude | Rolling session limits, weekly limits, and optional extra usage on eligible accounts | Claude usage indicators and Settings → Billing | Wait for the shown reset, reduce context, enable extra usage carefully, or change plans |
| Gemini | Plan-dependent access, feature limits, storage, and benefit eligibility | Google One plan details and the active Google account | Confirm the account and eligibility before upgrading or repurchasing |
| Grok | A shared weekly percentage pool across Grok products, plus Extra Usage Credits | Settings → Usage | Wait for the weekly reset, buy occasional extra usage, or compare a higher tier |
ChatGPT credits and usage
ChatGPT credits are not a replacement for Plus or Pro and are not a universal balance for unlimited ordinary chat. On eligible accounts, the included plan allowance is used first. Supported features can then draw from a shared credit balance after the included allowance is exhausted. The feature list can change, so the Usage Dashboard is more reliable than an old screenshot or a fixed list copied from another account.

Claude rolling limits, weekly limits, and extra usage
Claude limits are easy to misread because more than one meter can apply. A five-hour session limit and a weekly model allowance are different controls. Long conversations, large files, Projects knowledge, tool use, and high-compute models can consume capacity faster than short, clean chats. Starting a new conversation may reduce context cost, but it does not reset an account-level allowance.

Gemini limits and plan benefits
Gemini problems are often account or eligibility problems rather than a credit balance. A Google AI plan may be active while a particular benefit is unavailable because the wrong Google account is open, the user is a family member rather than the plan manager, the benefit has regional or age requirements, or the rollout has not reached the account. Verify the account and plan details before buying the same service again.

Grok weekly usage and Extra Usage Credits
Grok’s paid consumer system uses a shared weekly usage pool across products such as Chat, Imagine, Voice, and Build. The percentage is based on computation, not a fixed number of prompts. A high-quality video or long coding task can therefore move the meter more than a short text exchange. Settings → Usage shows the percentage used, product breakdown, reset time, and any Extra Usage Credits balance.

How to identify the limit before spending money
- Confirm the account. Check the email or sign-in provider that owns the subscription. Apple, Google, X, work, and personal accounts can remain separate even when the displayed name looks similar.
- Read the exact meter. Determine whether it is a rolling window, weekly pool, model allowance, feature cap, credit balance, or billing restriction.
- Check the reset time. Use the time shown inside the product. Do not assume every service resets at midnight or at the beginning of the calendar week.
- Separate a limit from a malfunction. Test a short request in a new conversation, another model where available, and the web or mobile app. If only one conversation fails, more credits may not solve the problem.
- Compare occasional overflow with a plan change. A small top-up can make sense for an unusual workload. Repeated top-ups may cost more than the next plan while providing less included capacity.
Price is only one part of the decision
App Store prices can differ by country, currency, tax treatment, and storefront. The lowest converted price is not automatically available to every buyer, and changing a store region can affect payment methods, subscriptions, balances, and account eligibility. Use the HiseHub AI subscription price comparison for verification, then check the official checkout shown to your own account.
How HiseHub maintains this hub
HiseHub reviews official product documentation and links each detailed guide to its controlling source. We distinguish consumer subscriptions from API billing, avoid presenting dynamic limits as guaranteed message counts, and record the verification date when a page is materially reviewed. Product rules can change after publication; the usage, billing, or checkout screen inside your account controls.
