About this list

  • Last reviewed: 2026-10-22. Names, availability and free quotas are checked by hand; we update the list after a site redesign or shutdown.
  • On each card, Mainland China means the service can be used directly with a mainland China phone number or email; Overseas service means it is provided outside mainland China. Both labels describe the product only and say nothing about network access.
  • We do not list wrapper sites, mirror sites, top-up resellers or shared accounts. To suggest a product, send us its name, official website and a one-line use case; we add it after testing.

Frequently asked questions

Can I use these AI tools for free?

Most offer a permanent free tier or a time-limited free plan. Free on a card means you can use it without paying; Free quota means you get an allowance after signing up; Subscription means it is paid. Exact limits depend on the official site, and we update this list after each review.

How should I choose between Chinese and overseas AI tools?

For writing in Chinese, looking up Chinese-language material and handling local office formats, Chinese models fit better and are easier to sign up for. For coding, long-document analysis and plugin ecosystems, overseas products have a longer track record. A common approach is one primary tool plus one backup; there is no need to pay for both.

I am new to AI. Where should I start?

Pick one task first: writing, images, video editing or coding. Open that category and read the how-to-choose section at the top, which maps scenarios to tools. Run with a single tool for two weeks before adding more.

Why open a detail page instead of going straight to the website?

The detail page explains what the tool does, who it suits and how to get started, so you do not forget why you saved it. The Website link on the card goes straight there.

Also on this site: text tools, coding tools, image tools, plus online tools, and Notes with field notes on actually using these tools.
