⌨️ Chromium Copy Shortcuts Extension

I built this lightweight Chromium extension in a few minutes to solve a small, stubborn drag: copying the same text over and over. It stores reusable snippets and copies them with one click, keeping repeat workflows fast without heavy formatting or cloud sync. The result is intentionally minimal, fully local, and one less excuse to context-switch during the day.

Toggle-Locked Access Across Tabs

Toggle lock keeps Copy Shortcuts visible across browser tabs, so reusable text stays within reach while the shortcuts themselves remain stored locally.

Toggle lock keeps the extension close at hand; Chrome keeps the shortcuts local.

Summary

This project solves a narrow but frequent problem: repeated text insertion. Instead of digging through docs, notes, or old messages, I keep reusable snippets in one popup and copy them instantly. Keeping it local and dependency-light was the core decision: the extension opens quickly and has fewer ways to get in its own way.

  • I kept copying the same snippets: email signatures, account notes, support replies, and short code fragments.
  • I wanted one-click recall from a browser popup instead of another trip through notes apps or old chats.
  • I wanted it fully local: no account, backend, or sync dependency.

Tech Stack

Chromium Extension (Manifest V3), HTML, CSS, vanilla JavaScript, Chrome Extension APIs (`chrome.storage.local`), Clipboard API with fallback copy support, shell-based packaging script.

Scope

There is no backend, account model, synchronization layer, or telemetry pipeline. The extension stays focused on local snippet storage, one-click copy, delete, and the small interactions that make a repeated task feel lighter.

Unlimited Local Phrase Creation

Create as many phrases as you need; every saved shortcut remains on your device in Chrome cache.

Adding another shortcut stays simple, and its storage stays local to Chrome cache.

Implementation Deep Dive

I kept the architecture deliberately small and explicit so every behavior is easy to reason about and maintain.

Architecture + Data Model

Single-surface extension with local persistence

Clipboard Path + Copy Reliability

Fast primary path with compatibility fallback

UX Behavior

Low-friction interactions for high-frequency actions

Privacy, Permissions, and Release Flow

Permission scope and release packaging were first-class engineering concerns, not afterthoughts.

Permission Minimization

Only what the extension needs

Build + Distribution
