Cloak — Scrub PII before AI

Remove names, companies, emails, numbers and other sensitive data before you paste into ChatGPT, Claude or Gemini. 100% on-device.

Every day, people paste sensitive information into ChatGPT, Claude, and Gemini without a second thought. Client names. A colleague's email. An account number. Last quarter's revenue. The moment you hit enter, that data is on someone else's servers — and you can't take it back. Cloak fixes that. Cloak scrubs personal and company data out of your text BEFORE it ever reaches an AI tool — and it does the entire job on your own machine. No servers. No accounts. No data leaving your browser. Ever. ━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS ━━━━━━━━━━━━━━━━━━━━ 1. Paste your text into Cloak. 2. Cloak swaps every sensitive detail for a clean placeholder — "Sarah Chen" becomes [Person_A], "Meridian Capital" becomes [Company_1] — consistently, everywhere it appears. 3. Copy the safe version into ChatGPT, Claude, Gemini, or any AI tool. 4. Paste the AI's answer back into Cloak's Reveal tab, and your real values are restored in one click. Because the same name always maps to the same placeholder, the AI still understands who's who and gives you a coherent, useful answer. This is the difference between Cloak and basic redaction tools that just black everything out and leave the AI confused. ━━━━━━━━━━━━━━━━━━━━ WHAT CLOAK DETECTS ━━━━━━━━━━━━━━━━━━━━ - Names of people - Company and organization names - Locations - Email addresses - Phone numbers - Credit card numbers (validated, so it won't flag random digits) - Bank account / IBAN numbers - Social Security numbers - IP addresses - API keys and access tokens - URLs and ZIP codes - Numbers and statistics (optionally swapped for realistic dummy values) You choose exactly which categories to cloak. Turn off what you don't need, keep what you do. ━━━━━━━━━━━━━━━━━━━━ TRULY ON-DEVICE — AND THAT MATTERS ━━━━━━━━━━━━━━━━━━━━ Most "privacy" tools send your text to their server to process it. Think about that: to protect your data from one company, you hand it to another. Cloak refuses to play that game. Cloak's detection runs entirely inside the extension, on your computer, using a bundled AI model. Your text is never uploaded. Never logged. Never seen by us or anyone else. There is no network connection involved in the detection at all — you could disconnect from the internet and Cloak would still work. We can't see your data. That's the entire point. ━━━━━━━━━━━━━━━━━━━━ WHO IT'S FOR ━━━━━━━━━━━━━━━━━━━━ - Professionals handling client or customer information - Anyone in finance, legal, healthcare, or HR - Founders and operators working with sensitive business data - Developers who don't want to paste keys and internal details into a chatbot - Anyone who's ever hesitated before hitting enter on an AI prompt ━━━━━━━━━━━━━━━━━━━━ PRIVACY PROMISE ━━━━━━━━━━━━━━━━━━━━ - 100% on-device processing - No accounts, no sign-up, no tracking - No analytics, no telemetry, no ads - No access to the websites you visit - Free Cloak is built by yForest.ai — a studio building tools that respect the people who use them. Stop scrubbing your prompts by hand. Stop hoping you caught everything. Install Cloak and paste with confidence.
