ClipGate — Smart Clipboard Vault

Smart, encrypted clipboard vault for your browser. 100% local · zero cloud · fully private. Every time you copy text in your browser, ClipGate automatically saves it to your local vault and classifies it into one of 13 content types — error traces, URLs, JSON, shell commands, SQL, Docker configs, file paths, secrets, and more. Secrets are detected automatically, masked in the UI, encrypted with AES-256-GCM, and auto-expired. No plain-text secrets sitting in your clipboard history. Everything stays on your machine. Zero cloud, zero accounts, zero tracking. Your clipboard data never leaves your browser. ━━━━━━━━━━━━━━━━━━━━ WHY CLIPGATE? Most clipboard managers store flat text sorted by time. ClipGate understands what you copied. It knows the difference between an error trace, a JSON response, and an API key — and treats each one differently. Your clipboard, but it understands your code. ━━━━━━━━━━━━━━━━━━━━ FEATURES - Three capture modes: Auto (every copy saved), Manual (save via shortcut or right-click), or Off - 13 content types: errors, URLs, JSON, commands, SQL, Docker, diffs, paths, env vars, IPs, SHAs, secrets, and text - Secret protection: auto-detected, masked, encrypted at rest, auto-expired - Manual save: right-click → Save to ClipGate, or press Ctrl+Shift+S (⌘⇧S on Mac) - Pause & exclude: pause capture for 15min/1hr, or exclude specific sites - Time-grouped history: clips grouped by Today, Yesterday, This Week, Last Week, Earlier - Search & filter: find any clip by content or filter by type - Keyboard shortcut: Ctrl+Shift+V (⌘⇧V on Mac) to open the popup - Smart deduplication: no duplicate entries within configurable window - Per-clip info: character count, source site, and timestamp - Works on all Chromium-based browsers ━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS 1. Install ClipGate from the Chrome Web Store. No sign-up, no account, no configuration needed. 2. Copy anything on any webpage. In Auto mode, it's saved instantly. In Manual mode, right-click → Save to ClipGate or press Ctrl+Shift+S. 3. Open ClipGate with Ctrl+Shift+V. Your clips are organized by time (Today, Yesterday, This Week) and filterable by type. 4. Secrets (API keys, tokens, passwords) are automatically detected, masked with bullet characters, encrypted with AES-256-GCM, and auto-deleted after a configurable timer (default: 2 hours). ━━━━━━━━━━━━━━━━━━━━ SMARTER THAN A CLIPBOARD MANAGER Most clipboard tools treat everything as plain text. ClipGate classifies content, encrypts secrets, and lets you filter by type. It's a clipboard manager built for people who work with code, configs, and credentials. ━━━━━━━━━━━━━━━━━━━━ BUILT FOR PRIVACY - 100% local — your clipboard never leaves your machine - AES-256-GCM encryption for secrets - No analytics, no telemetry, no tracking - No accounts, no sign-up, no cloud sync - No network requests whatsoever - Manifest V3, minimum permissions ━━━━━━━━━━━━━━━━━━━━ PERFECT FOR - Developers copying code between IDE, terminal, and browser - Anyone working with AI tools — save your prompts for re-use - DevOps engineers handling configs, env vars, and commands - Anyone who copies a lot and keeps losing things to clipboard overwrites ━━━━━━━━━━━━━━━━━━━━ WHAT CLIPGATE DETECTS ClipGate uses pattern matching and entropy analysis to classify every copy in under 5ms: - Secrets & API keys: AWS keys, tokens, private keys, bearer tokens, JWTs, and high-entropy strings - Error traces: JavaScript TypeError, Python tracebacks, Java stack traces, Go panics, Rust panics - JSON: API responses, config objects, package.json snippets - Shell commands: docker, git, npm, kubectl, curl, ssh, and more - SQL: SELECT, INSERT, CREATE TABLE, ALTER, CTEs - URLs: full URLs with protocol, query params, and fragments - File paths: Unix and Windows absolute/relative paths - Environment variables: KEY=VALUE pairs, .env file content - Docker: Dockerfiles, docker-compose YAML - Diffs: git diff, unified diff format - IP addresses: IPv4 and IPv6 - SHA hashes: commit SHAs, checksums - Plain text: everything else ━━━━━━━━━━━━━━━━━━━━ PERMISSIONS EXPLAINED ClipGate requests only the minimum permissions needed: - clipboardRead: to read what you copied - storage: to save clips and settings locally - activeTab: to know which site you copied from - contextMenus: for the right-click "Save to ClipGate" option - scripting: to capture clipboard content via keyboard shortcut - host_permissions (all URLs): so the content script can listen for copy events on every page No background network access.
