Defined-term gates
Change a defined term and every clause it touches stays locked until someone has looked at it. A clause cannot close while its knock-on exposure is unseen.
Lexara by aurus.ai
Know what you are signing. Then sign it.
Lexara puts contract review and e-signature on one platform. Read every clause with the people across the table, settle it online, and send it for signature with a record that holds up.
ink.aurus.aiSigning what other people send you is always free.
Send a document for signature.
Drop it, mark it, send one link. No password on either side.
A signature is only worth the record behind it.
Verified senders, separate consent, and a trail nobody can quietly edit.
Forms that fill themselves.
A purchase agreement in about 10 minutes, not 45, in our walkthroughs.
One platform, two ways to work
Start with Lexara Ink. Add Document Assessment when your contract team is ready.
Agree it with the other side, in one place
Your counterparty reads the clause, answers it and proposes their wording right where the clause sits. You reply in the same thread, email them from inside the review when you need to, and keep internal notes the other side never sees.
No attachments going back and forth, no version named final_v7, and no email chain to reconstruct when someone asks how a term was agreed.
See the risk before anyone signs
Every clause is rated critical, high, moderate or cosmetic, and so is what is missing. A contract with no limitation of liability is flagged before it is signed, with the wording to ask for already drafted.
Raise it, propose yours, escalate or set it aside. Each decision is logged with who made it, and the cover memo writes itself from the positions you took.
Forms that fill themselves
Drop the listing sheet and the property, sellers and listing agent fill in. Answer about fifteen plain questions and the deposit, loan amount and every deadline are worked out for you, with a warning beside any value that does not add up.
Every signature and initial, for every party, is placed before you see the send screen. Nothing goes out until you send it.
A library of 59 California real-estate and mortgage forms, 21 ready to fill today.
A signature that holds up
The sender is verified before anything goes out. Consent to sign electronically is recorded on its own, under ESIGN and UETA, with the exact wording each signer saw.
Every signed document carries a certificate and a trail that cannot be quietly edited. Anyone holding the PDF can check it against our records, with no account and without asking you.
One platform, from first read to final signature
Lexara Document Assessment tells you what is in a contract before anyone signs. Lexara Ink gets it signed, sealed and provable. One sign-in, one record of the whole deal.

Built for the person sending and the person signing
Sending
- Several documents go out as one envelope, signed in one sitting, each with its own certificate.
- Each signer is a tab in their own colour; every field you place belongs to them.
- Signing groups and order: buyers first, then sellers, is one drag.
- Initials on every page of every document, in one click.
- Drafts are kept for 10 days so you can finish later.
- Inbox and Outbox in one table: who has signed and who it is waiting on.
Signing
- One link, one code. No account, no password.
- Guided from field to field, with a count of what is left.
- Draw, type or upload a signature once; uploads lose the paper and keep the ink.
- A highly engaging finish that keeps signers moving to the last field.
- Full-screen signing on a phone.

Private by default
Encrypted throughout
In transit and at rest. Saved signatures sit in encrypted storage.
AI on a short lead
Used only where it helps, scoped to your account, and fenced off so text inside a document cannot give it instructions.
Nothing kept that you did not keep
Listing sheets are read and discarded. Delete any document permanently whenever you want.
