在 Gmail 和 Outlook 中按你本人语气撰写邮件的 AI 助手
ForthWrite 读取你已发送的邮件来建立语气档案，约每 50 封采集邮件刷新一次，让草稿持续跟上你写作风格的变化。
Pro 用户打开 Gmail 时回复已备好，并可并行处理数十个线程，无需逐封手写。
草稿会依收件人调整语气，并把跟进、引荐、进度汇报视为各自不同的任务，而不是套用同一模板。
对提示词做版本管理与 A/B 测试，并通过可量化的改进曲线追踪采纳率、语气匹配度和意图分布。
把各大 AI 模型与网页自动化合而为一的浏览器智能体
在一个扩展里切换 GPT、Claude、Gemini、Perplexity、DeepSeek 等模型，无需在多个标签页或订阅之间来回切换。
总结长文、PDF 与 YouTube 视频，就内容继续追问，或直接跳到视频中的相关时间点。
跟踪页面变化、商品降价与补货提醒，覆盖主流电商网站，并在有变动时通知你。
从网站抽取结构化数据、填写表单、走完点击流程，并触发 Zapier、Make.com、IFTTT 或 n8n 链路。
提供实时语法纠错、语气校准、写作来源追踪与团队风格指南的跨平台 AI 写作助手。
