I built a Windows screen recorder that auto-zooms and blurs API keys and emails for you (free to use)

Hey everyone, I’m a solo dev. I kept recording product demos and then worrying I’d left an API key or an email on screen. Re-recording or blurring frame by frame took forever, so I built CyanFocus. What it does: Every click becomes a smooth, editable zoom It scans your recording for API keys, emails and card numbers and blurs them, tracking them even while you scroll. You can review and untick anything before export Five cursor styles, captions, export up to 4K Everything runs l

痛点：录屏做产品演示时容易无意间暴露 API Key、邮箱、卡号等敏感信息，逐帧打码或重录极其耗时。

目标用户：需要录制产品 demo、教程、销售演示的独立开发者、技术博主、DevRel、SaaS 销售与客户成功团队。

证据：I kept recording product demos and then worrying I'd left an API key or an email on screen. Re-recording or blurring frame by frame took forever... It scans your recording for API keys, emails and card numbers and blurs them... It's free to use, and Pro just removes the watermark.

变现：Freemium：免费版带水印，Pro 订阅或一次性买断解锁去水印/4K/批量导出；后续可加团队版、CI 审核流水线、自定义敏感词规则。

MVP：做一个轻量桌面工具：导入已有录屏 → 本地 OCR 扫描 API Key/邮箱/卡号正则 → 自动打码并允许逐条勾选确认 → 导出 MP4。先不做实时录屏，只做"事后自动脱敏"这一刀，用 Python/Tauri + PaddleOCR 两周可出原型。

竞品：Loom、ScreenPal、CleanShot X、OBS Studio、CyanFocus

摘要：一位独立开发者发布 Windows 录屏工具 CyanFocus，自动生成平滑缩放并本地 OCR 识别打码 API Key、邮箱和卡号，全部本地运行不上传，免费使用、Pro 仅去水印。它验证了录屏隐私泄露这一真实痛点，但帖中没有任何付费用户或收入数据，付费意愿尚属推测。整体是可切入的方向，不过录屏赛道拥挤，需靠"自动脱敏"这一细分能力差异化。
