Guides

English AI tool buying guides

Use these guides to match the product category, delivery model and support boundary before opening the order channel.

How to use this hub

Start with the product you actually need. ChatGPT and Claude are broad AI productivity choices, Gemini and Grok are more ecosystem-specific, coding tools are workflow-specific, and SMS, email or virtual cards are support categories.

China-side supply can be useful for buyers who care about stock, delivery speed and flexible digital service categories. The right buying decision still depends on account ownership, platform policy, payment path and after-sale boundaries.

Decision path for new buyers

If you are not sure what to buy, start with the blocked step in your workflow. Need a general AI assistant? Compare ChatGPT and Claude. Need Google integration? Read the Gemini guide. Need X-related context? Read the Grok guide. Need development support? Start with the coding tools guide. Need registration or payment support? Read SMS, email and virtual card pages first.

Each guide is written to separate the product category from the delivery model. That matters because a subscription, a delivered account, an SMS code, an email account and a virtual card all have different support boundaries.
