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。
覆盖所有设备的文字转语音与语音 AI
用庞大的逼真 AI 声音库朗读书籍、PDF、文档和网页。
在 Google Docs、Gmail、Slack、Outlook 等几乎所有应用中口述，无需打字。
把文档或简短提示变成 AI 播客，并即时获取正在阅读内容的摘要。
网页应用、Chrome 与 Edge 扩展，以及原生 iOS、Android、Mac 和 Windows 应用。
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。
