I made a free screen magnifier you open by circling your mouse twice: no admin, no account, no CPU while the mouse is still

I kept zooming my whole screen to read one line, then zooming back, and every time it wrecked the layout of everything else. I also didn't want to lean in or reach for reading glasses. So I built a lens: circle the mouse twice (or tap Shift twice), and a magnifier opens at the pointer and follows it. Circle twice again to close it. Heads-up first: the exe isn't code-signed yet, so Windows shows "Windows protected your PC" the first time (More info → Run anyway). The other limi

AI 分析

痛点：系统级放大镜会破坏整个屏幕布局，用户只想在鼠标处看清单行小字，且不想戴老花镜或凑近屏幕

目标用户：视力下降/长时间读小字的开发者与办公人群、被锁权限（无 admin、无账号）的企业电脑用户、想为访客提供无障碍阅读的网站站长

证据：I kept zooming my whole screen to read one line, then zooming back, and every time it wrecked the layout of everything else. I also didn't want to lean in or reach for reading glasses. / it installs for you only, with no admin rights / A 7 KB gzipped script (npm i circle-lens, or one script tag) that gives your own site's visitors the lens.

变现：C 端工具免费做流量入口；真正变现放在 B 端：把 7KB 嵌入脚本包装成按域名/月订阅的网站无障碍阅读组件（对比 accessiBe 类产品的定价），或提供企业版（代码签名、静默批量部署、更新服务器自托管）按席位收费

MVP：2 周内只做嵌入版：npm 包 + 一个托管 CDN 脚本 + 域名白名单校验的后端（Stripe 订阅、按域名发 license key），保留手势触发但默认改为可配置快捷键，先找 10 个内容站/A11y 需求站点免费试用换案例

竞品：Windows Magnifier、Sysinternals ZoomIt、macOS Zoom、accessiBe、UserWay、Chrome 放大镜类扩展

摘要：作者用 Go + 纯 Win32 写了一个免费屏幕放大镜：鼠标画两圈（或双击 Shift）即在指针处打开 4.5MB/13MB 内存的镜头，静止时零 CPU，无需管理员权限和账号，另有 Chrome/Edge 扩展和一个 7KB 嵌入脚本让站长给自己的访客提供放大镜。原帖只是发布贴，没有任何付费意愿或收入数据，C 端本身是免费工具；真正可挖掘的变现点是那个按域名嵌入的无障碍脚本（B 端订阅），但竞品（系统放大镜、ZoomIt、accessiBe 等）密集，付费意愿未被验证。
