Keystone

Attorney-supervised estate planning. Documents assemble deterministically from a versioned legal library that a licensed attorney must approve, get checked against the client's own facts, and are delivered only after that attorney's review and certification.

• No AI touches a client's documents. Every operative clause comes from a versioned, citation-backed library — drafted as attorney-review raw material and treated as unapproved, on every rendered page, until a licensed attorney signs off.
• Every check is deterministic. Findings are arithmetic on the client's facts — a stale beneficiary form, an unfunded trust, a missing guardian — not model opinion.
• Nothing ships without counsel. The review gate, the ten-point certification, and the audit trail are architecture, not policy.

Keystone is a productivity tool for attorneys. It is not a law firm and does not provide legal advice. Documents are not legal advice until an attorney approves them.
