Hey Product Hunt! I'm George, the founder of anonym.legal. I built this because I was tired of the same problem every compliance team faces: you want your team to use ChatGPT, Claude, or Gemini — but you can't let them paste customer data into it. The existing solutions (Nightfall at ~$1,000/month, Microsoft Purview requiring M365 E5 at €54/user/month, Endpoint Protector requiring endpoint agents on every device) are either too expensive, too complex to deploy, or too restrictive. They block data. They don't anonymize it. They don't let you actually use AI productively. I believe that every person, organization, and institution has the right to share information selectively — to disclose to a regulator only what a regulator is entitled to see, to collaborate with a partner only over data that has been explicitly authorized, to participate in commercial and public life without surrendering what must remain private. I believe this right must be practically exercisable by everyone — not only by organizations with compliance departments and enterprise software budgets. Privacy cannot be a privilege of scale. I believe that in a world where US law can reach any data held by any US company anywhere on earth, and where 77% of employees feed sensitive data into AI tools they do not control, the only architecture that can deliver a meaningful privacy guarantee is one where the data never leaves the user's control in the first place. Not contractual guarantees. Not privacy policies. Technical architecture. Zero-knowledge authentication. Local-first processing. Reversible encryption where the key belongs to the user. Offline-capable operation. EU jurisdiction, no exceptions. These are not product features. They are the minimum standard for any tool that claims to protect personal data. And I believe that 28 years of working inside the organizations that handle the world's most sensitive information — 28 years of watching the gap between regulatory intent and technical reality widen — has given me both the understanding and the responsibility to initiate what the ecosystem still lacks. To define the vision, assemble the right team, and ensure it gets built to the standard the problem demands. The right to anonymize personal information is not a technical feature. It is a fundamental right. And a right that cannot be practically exercised is no right at all. So I built anonym.legal with a different approach: **What makes it different:** 1. **Deterministic detection** — We use regex + mathematical checksum validation (Luhn, Modulo-11, Verhoeff algorithms) for structured identifiers like German Steuer-IDs, Swedish Personnummers, Polish PESELs, Indian Aadhaars, Brazilian CPFs. Same input = same output, every time. Auditable. No black-box AI guessing. 2. **Response de-anonymization** — This is the feature nobody else has. You type "Customer John Smith, SSN 123-45-6789" into ChatGPT. We anonymize it to "[PERSON_1], [SSN_1]" before it reaches OpenAI. ChatGPT responds. We de-anonymize the response so you read "John Smith" in context. AI never saw the real data. You got a useful answer. Compliance satisfied. 3. **48 languages** — Not just English. German, French, Japanese, Arabic, Hindi, Polish, Swedish, Korean, Thai, Vietnamese... all with native NER models (spaCy, Stanza, XLM-RoBERTa). 4. **6 platforms** — Web app, Desktop app , Chrome Extension (ChatGPT/Claude/Gemini/DeepSeek/Perplexity), Office Add-in (Word/Excel/Outlook), REST API, and MCP Server (Claude Desktop, Cursor IDE). 5. **€3/month** — Not €1,000/month. Transparent pricing. Free tier included. No "contact sales." **The stack:** - Detection: Presidio + spaCy (25 langs) + Stanza (22 langs) + XLM-RoBERTa (48 langs) - Encryption: AES-256-GCM, format-preserving (16-digit card stays 16 digits encrypted) - Hashing: SHA-256, SHA-512, deterministic (database joins work) - Desktop: Tauri 2.0 + React 18 (offline-first, BIP39 key vault) - Extension: Manifest V3, local detection, no data sent to servers - Hosting: Hetzner Germany, EU data residency, ISO 27001 Happy to answer any questions about the architecture, compliance, or how we handle specific use cases.
