My software is still in diapers and nowhere near the size

AI scans competitors and market data to validate if a startup idea is worth building in 90 seconds.

预测市场最贵的,从来不是判断错。 而是当你发现异动时,聪明钱已经买完了。 所以,我做了一个双平台工具: 「信号罗盘」 Polymarket 500 个热门盘口 500 个热门盘口 两边各 50 个聪明钱地址 异动热度、收益曲线、每日评级和近期操作逻辑,全部放在同一个页面。 它不是喊单网站,也不承诺收益。 我们只想把分散的信息,变成更早、更清晰、可以验证的交易信号。 目前免费开放测试。 你最希望下一个加入什么功能:地址提醒、跨平台价差,还是聪明钱跟踪? #Polymarket #Predict #预测市场
