ScreenDot

Capture the visible browser viewport with a draggable dot and paste or upload it into browser-based editors when allowed.

ScreenDot puts a small, draggable pearl on every web page. One click captures the visible page. The next click in any chatbox, on any tab — attaches the screenshot automatically. No copy, no paste, no "find the attach button." How it works: Click the pearl. ScreenDot captures what you're looking at. Switch to ChatGPT, Claude, Gemini, Perplexity, or any other site with an upload field. Click the chatbox. The screenshot attaches itself. That's it. Cross-tab works seamlessly — capture on one tab, paste on another. Features: Works on ChatGPT, Claude, Gemini, Perplexity, and any site with a file-upload field Cross-tab handoff: capture in one tab, attach in another Drag the pearl anywhere on screen; resize via the bottom-right corner Right-click opens a color picker: 10 colors, 70 shades, plus Iridescent and Incognito modes Per-tab independence — moving the pearl on one site doesn't affect others Adjustable opacity (15–100%) via settings Respects reduced-motion accessibility preferences First-launch walkthrough teaches the gesture; never repeats after Privacy ScreenDot does not collect data. No remote server, no analytics, no telemetry. Every screenshot lives in your browser's local storage and clipboard. Permissions, in plain English activeTab — required to capture the visible viewport clipboardWrite — places the PNG on your system clipboard storage — remembers your pearl's color, size, and position across sessions scripting — injects the pearl on tabs you already had open when installing nativeMessaging — reserved for an optional desktop companion app (not yet released) host_permissions: <all_urls> — required so the pearl works on every page, not just specific sites
