Confidentiality Redactor for legal AI
Paste a letter, clause or note. Names, emails, phone numbers, amounts, dates, addresses and references are replaced with consistent placeholders — so you can use AI on the substance without exposing the client. When the AI replies, restore the originals in one step.
Go further than a single tool
AI for Lawyers 2026 covers the tools worth using, the regulation and 100 practical prompts across nine practice areas. The Professional Programme teaches the method live, on real legal scenarios.
Why anonymise before using AI?
Confidentiality is one of the core duties that professional bodies apply to AI use — the ABA’s Formal Opinion 512 is one example. Even on business plans that do not train on your data, the safest input is the minimum information the task requires. Most legal reasoning does not need the client’s name, the exact figure or the claim number.
Consistent placeholders matter. Because every mention of the same person becomes the same token, the AI can still follow who did what — and the key lets you put the real details back afterwards.
Frequently asked questions
Is it safe to paste client documents into ChatGPT or Claude?
Only on an appropriate business or enterprise plan, and with the minimum information needed. See why the plan matters more than the product.
Does this upload my text anywhere?
No. Everything happens locally in your browser. You can even disconnect from the internet after the page loads and it will still work.
How do I redact names without a title like “Mr”?
Add them to the custom list — for example, the client, counterparty and any project codenames.
Next: build a structured request with the Legal Prompt Builder, then verify the reply using our verification checklist. If your organisation needs a formal AI-use or data policy, TECHLAWG drafts them.
