Elysium Screenshot
Capture a page or region, annotate the result and export it from a browser extension.
Extension & editor development
The problem
Capturing something on a page often turns into a chain of separate tools: take the screenshot, crop it, explain the important part and prepare a file to share.
Engineering decision
The product is organized around the capture-to-export journey. Browser integration and image editing are separate responsibilities, making their behavior easier to reason about independently.
Workflow overview
Six TypeScript diagnostics remain, and a complete installed-extension capture/export flow has not been verified for this catalogue. The preview explains the workflow rather than simulating an extension.
Workflow
- Capture a page or region
- Annotate what matters
- Export an image or PDF
An explanation of the workflow, not an interactive application.
How it works
The extension brings capture modes, an annotation editor and export into one workflow. Browser background and content scripts coordinate capture, while the editor handles changes to the resulting image.
Collaboration & credits
Built with WXT and React; export and local history use supporting libraries including jsPDF and idb-keyval.
Verification details
The Chrome extension bundle built and 22 tests passed during verification.
