Feldr

AI-powered sensitive data detection for LLM interactions

Feldr keeps sensitive data from ever leaving your browser. Every prompt you type into an AI assistant — and every file you attach — can carry data you didn't mean to share: customer PII, health records, card numbers, API keys, internal code. Feldr inspects that content ON YOUR DEVICE, in real time, and warns or redacts it BEFORE it's sent to the AI tool. Nothing sensitive is uploaded to be scanned. Detection runs locally in your browser. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT FELDR DETECTS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Personal data (PII) — names, emails, phone numbers, addresses, dates of birth, and national IDs (SSN, Aadhaar, passport, driver's license, and more) • Financial data — credit/debit cards, CVV, IBAN, SWIFT, bank accounts, UPI, crypto wallets • Secrets & credentials — API keys (OpenAI, AWS, Google, Stripe, GitHub, and others), private keys, JWTs, passwords, database connection strings, .env secrets • Health data (PHI) — medical record numbers, ICD-10 codes, insurance IDs, NHS numbers • Prompt-injection attempts hidden inside pasted text and documents ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. You type a prompt or attach a file on a supported AI site. 2. Feldr scans the text, and the contents of PDFs, Word docs, images (on-device OCR), and even video frames — all locally. 3. If sensitive data is found, Feldr flags it and lets you redact it with one click, replacing values with safe placeholders. 4. Only after you're clear does the prompt go to the AI tool. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY-FIRST BY DESIGN ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Detection and redaction happen entirely on your device. • Your prompt text and files are never sent anywhere to be scanned. • Feldr records only lightweight detection metadata (e.g. "a credit card was detected and redacted") so security teams get visibility — never the sensitive value itself. Feldr helps teams use AI productively while reducing the risk of exposing regulated data — supporting privacy and security programs aligned with GDPR, HIPAA, PCI-DSS, and SOC 2 practices. Install Feldr and share prompts with AI tools with confidence.
