Don't just trust the answer — watch it get argued
Toggle Expert Panel on before you ask — that's all you do. An AI Senior Legal Advisor researches your question, assembles a panel of specialist AI junior advisors, and has them work in parallel and then debate — challenging weak findings in the open — before one cited conclusion is sent back to your chat. Transparency you can see, not just claim.

Built for the matters European lawyers actually run
Wherever the work is high-stakes, repetitive, or buried in documents.
Built for lawyers who can't afford a leak
Tero is GDPR-native by design. Your documents are end-to-end encrypted and stored as ciphertext sealed even from us — no one at Tero can read them. To answer a question, the AI decrypts only what that request needs, in memory and within the EU, then re-seals it: nothing is kept in plaintext, and nothing you put in is ever used to train a model.
