I got fed up with Rightmove saying "Reduced" without saying from what, so I built a free extension that shows the history

House hunting in the UK means staring at Rightmove's "Reduced on 23/10" and never knowing reduced from what, or how many times. So I built Curtain Twitcher, a browser extension that adds a panel to listings on Rightmove, Zoopla and OnTheMarket. 21-second demo: https://youtube.com/shorts/gReZUBjQV2o What it shows, free: the price history: every cut we've seen and by how much, and whether it was listed before what that home and similar ones nearby actually sold for (Land Registry),

AI 分析

痛点:英国购房者在 Rightmove 上只看到“Reduced”标签,却不知道原价多少、降了几次、历史成交价如何,信息严重不透明。

目标用户:英国买房者、租房者,以及需要快速评估房源的房产投资者

证据:"I got fed up with Rightmove saying 'Reduced' without saying from what" / "the deeper report is a one-off £9.99 pass rather than a subscription, because nobody wants another subscription while they're buying a house."

变现:Freemium:核心价格历史免费,9.99 英镑一次性付费解锁深度报告(洪水、氡、煤矿、地稳、产权、印花税等 30 项核查),后续可加按邮编订阅或给中介/买家代理的 B2B 授权

MVP:2 周内只做 Chrome 扩展:仅支持 Rightmove,抓取并本地缓存用户浏览过的房源价格变动(从“Reduced on”日期起记录),叠加 Land Registry 公开成交数据做同街区对比,深度报告人工半自动生成,先验证 9.99 镑的转化率

竞品:PropertyLog (Chrome 扩展)、PropertyData、HousePriceHistory、Zoopla 自带价格历史、Patma

摘要:作者因 Rightmove 只显示“已降价”却不给原价,做了浏览器扩展 Curtain Twitcher,覆盖 Rightmove、Zoopla、OnTheMarket,展示价格历史、Land Registry 成交价、30 项公开数据核查。后端为单 Node 服务 + node:sqlite,存有 3160 万条成交记录,最难的是房源与 EPC 地址匹配。变现采用 9.99 镑一次性付费而非订阅,有一定真实痛点,但同类价格历史扩展已存在,且数据工程量大。
