What is LeakSnitch?

Watch this quick intro to see how LeakSnitch blocks secrets, saves reputations, and makes AI cry (just a little).

Features that don't suck

Powerful tools to protect your sensitive data across all AI platforms

Blocks All the Things

From API keys, OAuth tokens, Stripe secrets, and OpenAI keys to session cookies, bank details, medical data, Slack channels, and even your boss's favorite YAML file. If it's sensitive, we block it. (Yes, even that.)

Redact Mode

Toggle Redact Mode to automatically turn password: secret123 into password: redacted and api_key: dasfdsfdsfsdfsdafasd into api_key: redacted. Impress your boss, confuse the AI, and keep your secrets secret (and stylishly redacted).

Zero Trust, Zero Storage

We don't store any of your data. Everything is processed locally. We're not your typical data-hungry startup. We're the opposite.

Custom Pattern Builder

Build your own regex patterns (without crying). Real-time testing, confidence scoring, and a regex help guide for when you forget what [a-zA-Z0-9] means. Validate before you unleash your inner regex wizard.

Whitelist Management

Domains, IPs (yes, even CIDR), and data patterns. Whitelist what you trust, block what you don't. Add, remove, validate, and pretend you're the firewall admin your company deserves.

Settings Profiles

Default, Work, Personal, or "I have trust issues". Switch profiles with one click. See stats, import/export, and give each profile a snarky description. Because your secrets deserve organization (and a little drama).

Detection Statistics

Charts, stats, and numbers for your inner data nerd. See blocked, warned, allowed, false positives, and more. Export, clear, and brag about your detection rate (or just cry at the false positives).

Time-based Analysis

Pick a time range (24h, 7d, 30d, or "since the dawn of leaks"). See hourly peaks, daily trends, and when you're most likely to leak secrets (spoiler: it's always Monday). Advanced filters and export included.

How It Works (No BS)

Simple, effective, and privacy-first protection in three easy steps

1

Install & Chill

One-click install. No configuration needed. We're not your typical software that requires a PhD to set up.

2

Smart Detection (Privacy-First)

We scan your clipboard and keyboard input locally for sensitive data patterns. Everything happens on your device - we never see, store, or log your data. Your privacy is our priority.

3

Protection Mode: Activated

When you try to paste sensitive things into an AI tool, we block it faster than your ex blocks you on social media. Crisis averted.

The Journey of Your Secrets

See how your sensitive data travels and how we protect it

1. The Copy-Paste Moment

Someone copies sensitive data (API keys, credit cards, personal info) ready to paste it into ChatGPT for "help".

2. The AI Feast

The AI model gobbles up your sensitive data, storing it in its training data. Now it knows your secrets better than you do.

3. The Data Leak

Your sensitive data becomes part of the AI's knowledge base, potentially accessible to anyone who knows how to prompt it right.

4. The LeakSnitch Save

But wait! LeakSnitch detects the sensitive data and blocks it faster than you can say "Oops, I shouldn't have done that."

Ship prompts without leaking secrets

LeakSnitch monitors and blocks API keys, tokens, and sensitive text before it reaches AI tools. Add it to your browser and relax.
