展示HN：PostFast – 基于AI的文案写作浏览器扩展程序
我们创建了PostFast，以简化创作者和营销人员生成特定平台文案的过程。您只需一次性配置您的产品信息，PostFast就会利用人工智能生成适合不同平台的定制内容，而无需手动调整同一产品信息以适应Twitter、LinkedIn或新闻通讯等平台。
主要功能：
- 一次性设置您的产品或服务
- 生成适应不同平台的文案（风格、语气、长度）
- 包含文案评分和A/B版本比较
- 提供基于AI的推荐，帮助您选择使用哪个版本
- 所有功能均在浏览器内完成，无需外部应用
PostFast专为独立创作者、内容团队和需要快速、一致文案的营销人员设计，避免在多个工具之间切换。我们专注于使其灵活且不带偏见——您控制输入，扩展程序处理格式和平台细节。
我们即将上线并开放候补名单。如果您经常撰写推广文案，我们非常希望您能提供以下反馈：
- 您最常发布到哪些平台
- 哪种评分标准对您有帮助
- 您是否希望有一个有限生成次数的免费版本

We built PostFast to simplify how creators and marketers generate platform‑specific copy. Instead of manually adapting the same product info for Twitter, LinkedIn, or a newsletter, you configure your product once, and PostFast uses AI to generate tailored content.<p>Key features:
- One‑time setup for your product or service
- Generates copy adapted to different platforms (style, tone, length)
- Includes copy scoring and A/B variant comparison
- AI-powered recommendations for which version to use
- All inside your browser; no external app needed<p>It's built for indie makers, content teams, and marketers who need quick, consistent copy without jumping between tools. We focused on making it flexible and non‑opinionated—you control the inputs; the extension handles the formatting and platform nuances.<p>We're launching soon and opening a waitlist. If you regularly write promotional copy, we'd love your feedback on:
- Which platforms you post to most
- What kind of scoring criteria would be useful
- Whether you'd prefer a free tier with limited generations<p>Waitlist and brief demo: [<a href="https://postfast.today/#subscribe" rel="nofollow">https://postfast.today/#subscribe</a>]<p>(I’m one of the developers.)
