How It Works

Three steps. Zero setup. Your way.

Install the extension and let it run automatically — or turn off auto-capture and save only what matters via right-click or Ctrl+Shift+S.

1You Copy

Copy anything on any webpage. In auto mode it's saved instantly. In selective mode, right-click → Save to ClipGate or press Ctrl+Shift+S.

2We Classify

In under 5ms, ClipGate identifies what you copied — error trace, JSON, secret, command, URL — using pattern matching and entropy analysis.

3We Protect

Secrets are detected, encrypted with AES-256-GCM, masked in the UI, and auto-expired. Everything stays on your machine. Nothing leaves.

Features

Not another clipboard history.
A smarter clipboard for everyone who works with text.

13-Type Classifier

Automatically identifies what you copied — URLs, errors, JSON, commands, paths, SQL, secrets, and more. Every copy is tagged the moment it happens.

Smart Secret Masking

Detects 18 secret patterns (AWS, GitHub, Stripe, OpenAI...). Shows known prefix + masked body + last 4 chars — like your bank dashboard.

AES-256 Encryption

Secrets are encrypted at rest inside your browser. Not plaintext. Not accessible from outside. Encryption key stored separately.

Auto-Expiry

Secrets auto-purge on a configurable timer (default: 2 hours, max: 2 days). Set it once, forget it. Your secrets don't linger.

Search & Filter

Find any clip instantly. Filter by type, search by content, keyboard shortcuts. / to search, Esc to clear.

Two Capture Modes

Auto mode saves every copy silently. Selective mode lets you choose — right-click → Save to ClipGate, or Ctrl+Shift+S. Switch in settings anytime.

Classification Engine

Your browser clipboard speaks 13 languages.
Every copy is automatically recognized and tagged.

Every time you copy in your browser, ClipGate tags it automatically. Secrets get masked and encrypted. Everything else is instantly searchable and filterable from the extension popup.

Secret Protection

Your API keys deserve better
than plaintext storage.

Most browser clipboard tools store everything in plain text. ClipGate encrypts secrets, masks them in the UI, and auto-deletes them. Because a clipboard extension that leaks your credentials is worse than no extension at all.

18 Secret Patterns

AWS, GitHub, GitLab, Slack, Stripe, OpenAI, Anthropic, npm, PyPI, SendGrid, Twilio, Heroku, private keys, generic credentials, and high-entropy strings via Shannon analysis.

AES-256-GCM at Rest

Every detected secret is encrypted before touching IndexedDB. The key is stored separately in chrome.storage. Not visible in DevTools, not readable in disk forensics.

Configurable Auto-Expiry

Default: 2 hours. Max: 2 days. Secrets are purged every 60 seconds and filtered from the UI even before purge runs. Your call, your timeline.

Smart Masking

Shows the recognizable prefix (sk_live_, AKIA, ghp_) plus masked middle plus last 4 characters. You know which key it is without seeing the full secret.

Privacy Promise

We don't want your data.
And we built it so we couldn't have it even if we wanted to.

Zero Network

No HTTP requests. No WebSocket. No beacons. No pings. Check the network tab yourself.

Zero Cloud

No sync. No backup. No server. Your clips exist only on your machine, in your browser profile.

Zero Analytics

No tracking pixels. No usage telemetry. No crash reports sent anywhere. We don't know you exist.

Zero Accounts

No sign up. No login. No email. Install and use. That's it. We don't want a relationship.

Why ClipGate

Built different.

🤖

Smart Classification

The Problem: Other tools store everything as flat text.
Our Approach: 13 types auto-detected (errors, JSON, URLs, secrets, commands, paths, IPs). Instantly tagged and filterable.
🔐

Secrets Protected

The Problem: API keys stay in plain text. One breach exposes everything.
Our Approach: Detected secrets are AES-256 encrypted, masked in UI, and auto-expire. Encrypted key stored separately.
🛡

Privacy by Design

The Problem: Most clipboard tools sync to cloud or track usage.
Our Approach: Zero network requests, zero cloud, zero analytics. Everything stays on your machine. We can't see you.

Questions?

Common questions about ClipGate

Does it work offline?

Yes. ClipGate works 100% offline. Everything happens in your browser. No internet connection needed, no data sent anywhere.

What if I uninstall it?

Your clips stay in your browser profile's storage. Uninstalling the extension removes it from your browser but doesn't touch stored data. Reinstall anytime to recover.

Can anyone see my clips?

No. Clips are stored locally in your browser. Secrets are AES-256 encrypted. No cloud sync, no accounts, no third parties have access.

How much storage does it use?

Typically 2-10MB depending on history size. You can clear old clips anytime. Secrets auto-expire, freeing space. The extension itself is ~50KB.

Launched April 2026 on Chrome Web Store
