Atomic Clipper

About

Atomic Clipper

Clip any web content into a local research library, then export it as Markdown for your research projects.

---

How it works

Click the toolbar icon, then click Start Clipping. A crosshair cursor activates on the page — hover over any element to highlight it, click to select it. An inline save panel appears where you assign a category and save.

For articles and long-form pages, click Clip Article instead. Atomic Clipper automatically selects the main content block and opens the save panel — no pointing required.

Your research library

Every clip is saved to a local library, grouped by category. Open it anytime from the popup footer. When you're ready to use your clips, hit Export .md next to any category — one Markdown file downloads per category, ready to use in any research workflow.

The export format

Markdown is a widely used plain-text format that preserves document structure — titles, headings, paragraphs, blockquotes — exactly as the original source intended. No proprietary format, no lock-in. The exported files open directly in AI tools, note-taking apps, and any text editor that reads Markdown.

Privacy and permissions

Everything stays on your device. Atomic Clipper uses Chrome's local storage — no account, no cloud sync, no network requests of any kind. You can delete individual clips or all clips at any time from the library.

Three permissions, nothing else:
- activeTab — activates only on the current tab when you click the icon
- scripting — injects the element picker into the page
- storage — saves your clips locally

No host permissions. No access to your browsing history or cookies.

Open source

MIT license. All source code is on GitHub — the picker, extractor, storage, and export logic are all visible and auditable.

Known limitations

- Cannot activate on browser system pages (chrome://, about:, extension pages)
- Does not capture images inline — image URLs are stored as metadata only
- May not clip correctly behind login walls or paywalls
