I built a free scam detector: paste a shady link/message, get a plain-English verdict

Hey all, I built Phltr (phltr.net) after watching people in my life nearly fall for phishing texts that were obviously scams to me but not to them. It does three things: paste a link or message (or upload a screenshot) on the site, send it to a WhatsApp bot, or forward a suspicious email to check@phltr.net . It checks links against trusted safety lists, scans wording for urgency/impersonation/requests for sensitive info, and reads screenshots, then gives you a plain-English verdict: safe

痛点：普通人（尤其长辈）无法辨别钓鱼短信/链接/邮件，需要一个多语种大白话的当场上手判别工具

目标用户：非技术用户的家庭成员（父母长辈）、中小企业员工、需要反诈防护的普通消费者

证据：I built Phltr (phltr.net) after watching people in my life nearly fall for phishing texts that were obviously scams to me but not to them. … Free, no account, no sign-up. … I'd love feedback on the verdict explanations.

变现：C 端免费引流 + B 端收费：向银行/电信/保险/企业做反诈白标 API 或员工防护订阅；或家庭版高级功能（多设备监控、诈骗趋势周报）订阅制

MVP：2 周内做 WhatsApp/邮件/Telegram 三入口的转发即检测机器人：接 Google Safe Browsing + VirusTotal + LLM 判定并输出三段式大白话结论，先不做网站

竞品：Google Safe Browsing、VirusTotal、ScamAdviser、Norton/Symantec 反钓鱼、Truecaller、Whoscall

摘要：独立开发者在 r/SideProject 发布免费反诈检测工具 Phltr，支持粘贴链接/消息、WhatsApp 机器人和转发邮件到 check@phltr.net，输出 safe/suspicious/scam 的大白话结论，无需注册也不存储数据。作者称动机是家人差点被钓鱼短信骗到，目前完全免费、无任何付费或收入数据，仅在征求结论解释文案的反馈。痛点真实且广泛，但付费意愿未被验证，且 Safe Browsing、VirusTotal 等竞品密集。
