14 AI Writing Tools Compared (2026): Pricing, Free Quotas, and Real Limits

Primary intent: Shortlist tools for one task using clear criteria

To pick an AI writing tool fast, match your scenario to a tool with public pricing: for Chinese office documents, 办公小浣熊 (Office Xiaohuanxiong); for e-commerce and social copy, 稿定AI文案 (Gaoding AI Copy); for medium-to-long-form drafts, GetDraft or YouMind; for English proofreading, Grammarly; and for polishing English research papers, 笔目鱼 (Bimuyu). Each of these publishes its pricing, and we checked it on 2026-07-17. Most of the rest quote a price only after you contact sales or log in, so read on by scenario.

These 14 tools are the full AI Writing category on this site, ordered by how verifiable their public pricing is: tools with line-item prices we checked come first, tools that reveal a price only through a sales call or a login come next, and tools that post no price at all come last. This is not a ranking by draft quality, because we have not independently tested each tool’s output, and it is not ordered by clicks, because the on-site click sample is still too small. Every entry names at least one real limitation that can affect your decision.

办公小浣熊 (Office Xiaohuanxiong): the clearest free quota for reports and briefings

办公小浣熊 suits office workers who write briefings, build reports, and organize source material, and its free quota and paid tiers are labeled more plainly than most peers. The free plan allows 20 AI chats and 5 web searches per day with 500 MB of storage; to lift those caps, the personal upgrade starts at CNY 29.9/month and the enterprise standard plan at CNY 1,599 per user per year (vendor pricing, checked 2026-07-17). Heavy users hit the free cap quickly, and rolling the enterprise plan out to a whole small team is not cheap. The “2,000+ enterprise customers” figure on the site is vendor-reported and not independently verified.

稿定AI文案 (Gaoding AI Copy): copy alongside Gaoding’s design tools

稿定AI文案 fits social and e-commerce operators who already use Gaoding for design and want to handle copy in the same place. Free downloads carry a watermark and no commercial license; for commercial use, the cheapest path is the template membership from CNY 8/month, while full AI creation and asset downloads sit in the membership from CNY 16.5/month (vendor pricing, checked 2026-07-17). There is no standalone AI-copy product page, so the feature is spread across the platform’s creation entries, which takes adjustment if you want one dedicated copy tool.

GetDraft: daily-cadence creators and content teams

GetDraft is built for creators and content teams under daily publishing pressure. Signing up grants 800 free credits, enough to test a few pieces, and sustained use runs on the PLUS plan from HKD 149/month (vendor pricing, checked 2026-07-17). Credits expire 60 days after they are issued, so a low-output month wastes the allowance, and billing in Hong Kong dollars adds payment and exchange-rate friction for mainland users. The interface and templates center on Chinese content, and English writing support is limited.

YouMind: turn scattered ideas into finished pieces

YouMind suits creators who need to shape scattered notes into finished work. The free plan limits AI credits and caps uploads at 100 files, so heavy use runs into the ceiling, and the Pro plan costs USD 20/month (vendor pricing, checked 2026-07-17). For a writing-only workflow, that price sits on the high side. Its macOS client is still in beta, so test stability before you rely on it.

笔目鱼 (Bimuyu): polish English papers to submission quality

笔目鱼 suits researchers who need to bring an English paper’s language up to submission standard, with polishing, translation, and an example-sentence library available for free (vendor information, checked 2026-07-17). Its VIP price is not shown on the membership page; you see it only inside the checkout flow, so read the benefits and renewal terms before you order. It handles English papers only, not Chinese writing, and its “reduce AIGC” feature carries integrity risk in academic settings, where some journals and schools require honest disclosure of AI use.

Grammarly: a second editing pass for English text

Grammarly works as a second editing pass for English text, and it has a free plan (vendor information, checked 2026-07-15). Our records hold no verified paid price, so we do not quote one here; check the site for current figures. Supported features differ by entry point, and generative features are limited by plan and settings. Leave factual accuracy, domain meaning, and AI-detection calls to human judgment rather than the tool.

小鱼AI写作 (Xiaoyu AI Writing): many templates on a small budget

小鱼AI写作 fits people who want a lot of AI writing templates on a limited budget, on a freemium model (vendor information, checked 2026-07-17). The free plan caps daily generations, but the exact quota is not published, and some advanced features, such as lifetime VIP, require payment. Output quality depends on the template and your input, so complex tasks often need several passes, and it falls short if you want top-tier models or deep customization.

万能小in (Wanneng Xiao In): academic and office documents, price on request

万能小in targets people who need to generate academic or office documents quickly, but its pricing is not public and the site only invites you to contact sales (checked 2026-07-17). Free-plan details are not provided either, and the site leaves feature specifics and quotas unstated. Without a public price or quota, side-by-side comparison before purchase is hard, so settle the terms first if that matters to you.

讯飞绘文 (iFlytek Huiwen): running multi-account content operations

讯飞绘文 suits teams running multi-account operations across channels such as WeChat Official Accounts and Toutiao, and it is operations-focused rather than a general writing assistant. A single account or a light user leaves most of its features unused. The site shows subscription plans only (monthly, or annual at 30% off), with the actual price visible after login rather than posted openly. Publishing its batch-generated posts directly risks platform penalties, so keep a human review step.

笔灵AI写作 (Biling AI Writing): broad coverage, strong on papers and social media

笔灵AI写作 covers a wide range of scenarios, with especially many templates for academic papers and social media. Its homepage does not post membership prices; you confirm the cost only at checkout. Its “reduce AI traces” and “reduce duplication” features carry integrity risk in academic settings, and some schools ban them outright, so check your school’s or journal’s rules before using them on a paper. AI-generated paper text still needs a human to check facts and citations before submission.

维普科创助手 (VIP Kechuang Assistant): literature work with the VIP database

维普科创助手 suits students and researchers doing literature work with the VIP (Weipu) database. Its pricing is not public, and you confirm the free quota and paid tiers only after registering and logging in, so trial it first if that bothers you. The “6.62 million+ users trying it” figure on the page is vendor-reported and not independently verified. Its “one-click model essay” feature carries integrity risk, and submitting generated text directly may violate school or journal rules.

光速写作 (Guangsu Writing): quick drafting help for students and office workers

光速写作 is aimed at students and office workers who need to produce articles or writing assistance quickly. The site does not state a free quota or a paid price, so you may have to contact sales to confirm. Generated text can lack depth and needs human review and editing, and the tool currently supports Chinese only, with English and other languages unaddressed on the site. It is a poor fit when originality demands are high or the work calls for deep, original writing.

墨问 (Mowen): quick note capture with automatic organization

墨问 fits people who jot down ideas often and want them organized automatically. It does not support rich text such as tables and code blocks, and it has no export, so your data stays locked inside the app. It offers no team collaboration or sharing today, so it falls short for complex document editing or multi-person work. The site does not post a clear paid price.

新华妙笔 (Xinhua Miaobi): official-document and news writing

新华妙笔 suits users who need to finish official documents or news pieces efficiently, and creative or non-Chinese writing is not its focus. It supports Chinese only, and its creative-writing support is limited. The free plan may be restricted and advanced features require payment, with no clear price posted on the site. For writing outside official documents and news, look at the other tools in this list.

How to match a tool to your work

Map these 14 tools to your own work: 办公小浣熊 for Chinese office documents, 稿定AI文案 for e-commerce and social copy, GetDraft or YouMind for medium-to-long-form drafts, Grammarly for English proofreading, and 笔目鱼 for polishing English papers. When a site only invites a sales call or hides the price behind a login, confirm the free quota and renewal terms before you pay. For any “reduce duplication” or “reduce AI traces” feature, check your school’s or journal’s AI-use rules first.
