skills.vn is not a traditional SaaS product, but a content-writing Skill that can be installed in Claude Desktop, Claude Code, OpenAI Codex, and Google Antigravity. It packages 14 copywriting formulas, 18 psychological effects, and 10 NLP techniques into protocol files that an AI Agent can read. After installation, users only need to enter an instruction such as “write content for a product,” and the AI will automatically choose the formula, tone, and persuasion strategy.
Its core value is lowering the barrier to prompt engineering. The formulas listed on the page include AIDA, PAS, FAB, BAB, Storytelling, Hook-Value-CTA, Funnel, and more, making it suitable for Facebook sales copy, social media captions, short-video hooks, product promotion posts, and similar scenarios. It emphasizes that the AI will automatically ask for the minimum required information, generate multiple angles, and select the stronger approach. However, the tool itself does not provide any model capability; the final quality still depends on the performance of the underlying model behind Claude, Codex, or Antigravity.
The price is a one-time payment of 299,000 VND, with the page showing an original price of 599,000 VND. After purchase, payment is made via VietQR bank transfer, and the files are sent by email within 5–10 minutes. The package includes versions for 4 platforms, a README, unlimited use, lifetime validity, free updates, and Zalo installation support. Integration is done by copying files into the specified directory; no standalone API is mentioned.
The advantages are its low one-time cost, suitability for frequent use, and the way it structures common marketing knowledge, making it useful for users who do not want to repeatedly copy long prompts. The drawbacks are also clear: it is essentially a Skill/prompt protocol rather than a standalone AI product; the page does not disclose a detailed privacy policy or refund policy, and there is no systematic quality evaluation. The page content is in Vietnamese, and Chinese-language support is not specified.
It is better suited to Vietnamese content creators, small merchants, marketers, and users who are already using Claude, Codex, or Antigravity. Users in China should note that the page does not state whether it is accessible from mainland China, and payment relies on VietQR, making cross-border purchases inconvenient. At the same time, the availability of Claude, Codex, and Antigravity in mainland China may also be affected by network and account restrictions. Alternatives include building a Chinese prompt library yourself, or using Chinese writing tools such as 通义千问, 豆包, or 秘塔写作猫 together with copywriting templates.
