Everything between capture and publish.
Stop screenshotting tabs and cropping in five apps. Capture exactly the element you mean, and let AI do the wordsmithing.
Pixel-perfect bounding boxes
Hover any element and watch a precise bounding box snap to its edges. No more guessing where the screenshot ends.
One shot, many elements
Click to select — then click more components and capture them all together in a single precise screenshot.
AI caption engine
Gemini or OpenRouter reads your capture and writes platform-ready captions with the right tone and hashtags.
7 platforms, 18 languages
Facebook, Instagram, TikTok, X, LinkedIn, Threads and Zalo — captioned in your language, not a broken translation.
Your brand voice
Configure a persona: brand name, industry, audience, tone and hashtags. The AI writes like your team, not like a robot.
Built-in editor
Polish your capture with gradient backgrounds, frames, drop shadows and watermarks — before it ever leaves your browser.
Three steps. Thirty seconds.
From page element to publish-ready caption without leaving your tab.
Activate
Click the CapAnything icon and the page enters selection mode with a crosshair cursor.
Select & capture
Hover to preview the bounding box, click to select one or multiple elements, and capture the exact region.
Generate & post
AI writes per-platform captions and hashtags. Copy, paste, publish.
One capture. A caption for every platform.
The same screenshot, rewritten for each platform's voice — tone, hashtags and character limits handled automatically.
Silence is golden — until it sounds this good. 🎧 Meet Aurora, engineered for pure focus. Sound like a pro, feel like you.

The extension itself is free. AI caption generation uses your own API key (Gemini or OpenRouter), so you only pay what those providers charge — many models have generous free tiers.
