Memory Crystal - Clipboard & Copy History

Preserve everything you press Ctrl+C on as searchable Shards. Pin favorites, filter links and code, and recall copies instantly.

Memory Crystal preserves a searchable local history of everything you copy in your browser so you never lose an important snippet, link, or paragraph when pressing Ctrl+C again. FEATURES • Automatic Copy History — Captures text copied via Ctrl+C (or Cmd+C), right-click Copy, and website Copy buttons automatically as Shards. • Crystallize Favorites — Pin important Shards so they stay permanently protected even when clearing old history. • Instant Search & Smart Filters — Quickly filter your saved Shards by All, Crystallized (Pinned), Links, or Code snippets. • One-Click Recall & Direct Channel — Click any Shard (or press Enter) to copy it back to your clipboard, or press Shift+Enter to paste it directly into the active text box on the page. • Popup & Side Panel Views — Open Memory Crystal as a fast keyboard-driven popup (Ctrl+Shift+Y / Cmd+Shift+Y) or dock it into your browser Side Panel for side-by-side research. • Privacy Guardrails (Dormant Mode & Shielded Realms) — Pause capture with one click or add sensitive websites to your Shielded Realms list so copies on those sites are never recorded. HOW TO USE 1. Copy any text on a webpage using Ctrl+C (Cmd+C), a website Copy button, or right-click and choose "Inscribe into Memory Crystal". 2. Click the Memory Crystal icon in your toolbar (or press Ctrl+Shift+Y / Cmd+Shift+Y) to view your saved Shards. 3. Click any Shard to copy it back to your clipboard, click the crystal icon to pin it forever, or click the lightning icon to paste it directly into the active field. PRIVACY This extension does not collect, transmit, or sell any personal data. All of your saved clipboard history and settings are stored strictly locally on your device and never leave your browser. Password input fields are automatically ignored. PERMISSIONS • "Read and change all your data on all websites" — Needed to detect when you copy text on a webpage, display confirmation toasts, and paste selected snippets into active input fields when requested. • "Read and modify data you copy and paste" — Needed to copy your selected Shard back to your clipboard and sync copied text when you open the extension. • "Read your browsing history" — Needed only to read the active tab's page title and domain so you can see where a snippet was copied from and block specific domains via Shielded Realms. Known Issues / Limitations - Chrome restricts content scripts on internal `chrome://` pages and the Chrome Web Store itself; copies made on those pages can still be captured when opening the Memory Crystal popup via `clipboardRead`.
