Clipboard Snippet Manager

Every developer, writer and student has a graveyard of useful text: the SSH command for the lab server, the perfect email follow-up, a regex that took an hour to write, a link to the report template. These live scattered across sticky notes, old chats and memory — and get lost exactly when needed. Clipboard managers solve the history half of this (what did I copy ten minutes ago), and snippet libraries solve the reuse half (the things I copy every week). This project builds both in one desktop application: a rolling clipboard history with timestamps, and a permanent, categorized, searchable snippet library with pinning. One click copies any snippet back to the clipboard with a confirmation toast. The data model is deliberately local-first — snippets live in on-machine storage — because the most useful snippets (server credentials, internal links, personal templates) are exactly the ones that should never sync to a cloud.

1. The app presents the snippet library as cards grouped by category, with pinned items first.
2. Adding a snippet opens a dialog for title, category and content; editing reuses the same dialog pre-filled.
3. The search box filters cards live by matching the query against titles and content (case-insensitive substring match).
4. The clipboard-history view shows recently copied items with relative timestamps, kept separate from the permanent library.
5. Clicking Copy writes the snippet text to the OS clipboard (via the clipboard API with an execCommand fallback) and shows a confirmation toast.
6. Pinning toggles a flag that re-sorts the library so pinned snippets always appear first.

Tech stack:

• Electron (desktop shell)
• JavaScript (library logic, search, clipboard)
• Clipboard API + execCommand fallback
• LocalStorage / file-based persistence
• HTML/CSS (card-based library UI)

• [Pinned snippet library] Pin the snippets you reuse daily; pinned items sort to the top and carry a visual marker so the important ones are always first.
• [Categorized organization] Code, Commands, Links, Email and Text categories with per-category counts keep different kinds of snippets from mixing.
• [Instant search] Filter the whole library as you type — searching "ssh" immediately surfaces the lab-server command.
• [Clipboard history] A rolling history of recently copied items with timestamps, separate from the permanent library.
• [One-click copy] Every card has a Copy button that returns the snippet to the OS clipboard with a confirmation toast.
• [Add and edit] A clean dialog adds new snippets or edits existing ones (title, category, content) without leaving the library view.
• [Local-first storage] All snippets persist on the machine; nothing syncs anywhere, which is a privacy feature for credential-adjacent content.

• Complete Electron desktop application source code
• Snippet data model and local persistence layer
• User manual: organizing a personal snippet library
• Project report PDF (background, clipboard architecture, local-first design, methodology)
• PPT presentation for final review
• Viva Q&A preparation document (clipboard APIs, Electron, data modeling, search)

• The demo tracks copies made through its own Copy buttons; OS-wide clipboard monitoring needs native hooks that are platform-specific and listed as a desktop-integration extension.
• Search is substring-based, not fuzzy — "shh" will not find "ssh"; fuzzy matching is documented as future scope.
• No cloud sync by design — snippets stay on one machine; multi-device sync would need an encrypted sync service (future scope).
• Large binary clipboard content (images) is out of scope; the tool manages text snippets.
• Import/export of snippet libraries (JSON) is a planned extension, not included in this version.
