Lorosign reading a long document and surfacing the parts that matter
Summary ready

An AI that reads the whole file, so you do not have to.

Drop in a 300-page agreement and Lorosign reads every line. It pulls out obligations, deadlines, and the clauses that put you at risk, then explains them in plain language.

  • Full-document analysis

    Every page parsed, not just the first few. Nothing skimmed.

  • Risk and obligation flags

    Auto-renewals, liability caps, and odd terms surfaced before you sign.

  • Ask in plain language

    Question any clause and get an answer with a citation to the exact line.

Your own reader

Build an agent that knows your documents.

Train a private agent on the way your team reads. It checks new files against your rules and helps anyone get through a long document in minutes.

A reader trained on your standards

Give it your playbook once. It applies the same checks to every contract that lands after.

Works across formats

PDF, DOCX, scans, and email threads. The agent reads them the same way.

Faster reading

Long files condensed to the points that change your decision.

Private by default

Your agent learns only from your documents. Nothing trains a shared model.

Build your agent

From a heavy file to a confident signature.

01

Upload anything

Drop in a contract of any length. Lorosign handles hundreds of pages without breaking a sweat.

02

Read with your agent

It summarizes the file, flags the risky parts, and answers your questions with citations.

03

Sign with proof

Place a legally binding signature. Every action lands in a tamper-evident audit trail.

Trust

Every signature stands up to scrutiny.

Signatures are legally binding under ESIGN, UETA, and eIDAS. Documents are encrypted in transit and at rest, and every view, comment, and signature is logged.

"We close on agreements that used to sit unread for a week. Lorosign reads the long ones overnight and tells us exactly what to look at."
