AI 分析

痛点：Grammarly、Quillbot 等语法和改写工具订阅价偏高（约 30 美元/月）、免费额度几乎无用，用户回复客户消息时还得在 ChatGPT 之间反复复制粘贴。

目标用户：需高频用英语回复客户的自由职业者、小商家客服、非英语母语的跨境电商/外包从业者。

证据：i found grammarly and quillbot and they were too expensive for me as the free tiers give me nothing !

变现：免费额度 + 3~6 美元/月的低价订阅，或一次性买断终身版；后续可加团队版与按场景（Slack/Discord/邮件）定价。

MVP：做一个 Chrome 扩展：在任意输入框旁提供悬浮按钮，一键调用 LLM 做语法修正、语气调整和改写，内置 3 档语气预设和每日免费次数，用 Stripe 做低价订阅。

竞品：Grammarly、Quillbot、LanguageTool、Wordtune、Harper、各类 AI 写作类 Chrome 扩展

摘要：开发者因 Grammarly/Quillbot 每月约 30 美元太贵、免费版几乎不可用，自建 Chrome 扩展 Wordmend，实现聊天框内直接润色改写。这印证了“低价 + 场景内嵌”的写作助手存在价格带机会，但该赛道竞品极多、差异化空间有限。
