Choose a starting point for account access, a limit notice, document work or Claude Code billing. Match the guide to the exact warning or purchase problem rather than starting with the newest model comparison.
What do you need help with?
Independent guides from HiseHub, not Anthropic support. Each guide states its own source and review scope.
A paid plan is missing
Start with the account, workspace and purchase-route checks.
A session or weekly limit stops you
Choose the guide matching the notice, then review extra usage only if billing is the remaining question.
A document will not upload
Use the file-specific guide for attachment, content and account-surface checks.
A conversation is too long
Use the continuation and handoff method before assuming a higher plan is the answer.
Claude Code is charging API credits
Follow the authentication and billing-route guide for the setup you are using.
Choose a plan or a model
A capacity comparison and a model comparison answer different questions; pick the decision you need to make.
Claude plan and account tools
Our guides separate plan access, five-hour and weekly limits, usage credits, billing, and account problems. When a rule can change, we identify the official source and the date checked so you can verify the live setting before paying.
- AI Model Access Map — see which Claude models or features a plan may expose.
- AI Subscription Troubleshooter — diagnose a missing plan, limit warning, refund route, or wrong account.
- Claude Pro Price by Country — compare published App Store listings and open the official source.
