AI writing tools

• Name the job before the brand: a full draft, an English line edit, or campaign copy. Those jobs sit in chat, writing, and productivity in this index.
• Read the China mark before you invest a draft. Offered, not offered, and not confirmed are three different public claims.
• Start with a free tier when the listing has one. Jasper is the paid listing on this shortlist. A free tier still has caps, and this index does not itemize them.
• Stay inside a workspace you already use only when the listing says so. Notion AI is that case. The other products here are separate sites.
• Keep the last pass for yourself. A fluent paragraph still needs a person to check facts before you publish it.

Ten listings. The line under each card is why it is on this page.

  A wider shortlist of products the index marks as offered in mainland China, beyond writing.

• AI presentation tools

  When the writing is a deck, Gamma and the slide-related listings are the next page.

• Which of these have a free way in?

  ChatGPT, Claude, Grammarly, Kimi, Doubao, ERNIE Bot, ChatGLM, Notion AI, and Spark are freemium in this index. Jasper is marked paid. The index records that shape and leaves the exact free quota on the vendor’s site.

• Which writing tools are offered in mainland China?

  On this shortlist, Kimi, Doubao, ERNIE Bot, ChatGLM, and Spark are marked offered. ChatGPT and Claude are marked not offered. Grammarly, Jasper, and Notion AI are not confirmed. Unknown means we did not find a clear public offer.

• Does NavBoth check a draft for plagiarism?

  The index does not score originality. Grammarly’s listing is English grammar, tone, and rewrites, which is a different job from generating an article. If you publish a draft, you still review it.

• When should I open ChatGPT instead of Jasper?

  Open ChatGPT for a general assistant whose listing covers drafting, coding help, and questions, knowing it is marked not offered in mainland China. Open Jasper when the job is marketing copy and brand voice on a paid plan.

• How do ChatGPT and Claude differ for writing?

  Both are freemium and both are marked not offered in mainland China. ChatGPT’s listing calls out drafting and coding help. Claude’s listing calls out long documents, writing, and analysis. The comparison page puts those claims side by side.

NavBoth is a directory of public products already in the index. These pages help you choose a listing. The product itself runs on the vendor’s site. Mainland China marks come from public offers reviewed with the seed; they are not a live connection test. No listing on these pages has a paid badge. Names belong to their owners.

Quotas, brand-voice settings, and copyright terms stay on the vendor’s site. This page records the price shape and the China mark we already publish, and it leaves the last editorial judgment with you.
