A free screenshot editor that never uploads your images — annotate, redact, and paste anywhere, all in-browser
RioShot is a free screenshot editor built around a radical simplicity: take a screenshot, paste it (Ctrl+V), annotate it, and paste the result anywhere. No upload, no account, no watermark. Everything happens inside your browser — the only time an image leaves your device is when you click Get link to share it.
The toolkit matches how makers actually communicate: arrows, highlights, blur and redact to hide private details, zoom callouts to point at tiny buttons, and a dark spotlight that dims everything except the number that matters. Fourteen before/after examples on the homepage show how much a single annotated screenshot can say.
It is also a vibe-coding case study. Maker Alberuni Azad announced it in the vibecodinglife Facebook group on October 1, describing “building and launching a free screenshot editing app called RioShot in a single sitting … development with Claude Code and the Opus 5.5 model” — from idea to domain purchase, testing, deployment and launch in one session.
Private by design, instant, and free — the rare annotation tool that never makes you wonder where your screenshots went.
