Redlineo

Legal / contracts

A contract redline you can prove — on your own servers.

Every tool compares a contract turn. Here the differentiators are not the diff — they are self-hosting and a verifiable certificate. Every redline Redlineo produces proves it is unaltered since generation and ties to exactly the input files, and no document ever leaves your infrastructure.

Same primitive, contract vocabulary

The analogous filing, and the analogous rate table.

The pattern behind this tool — a revised document, plus required proof of what changed — is the daily rhythm of contract negotiation. It is the same practice US insurance regulators built SERFF around; here, honestly, the redline itself is table stakes and the proof is the point.

  • The analogous filing

    Contract turns with opposing counsel

    Each turn gets a tracked-changes redline reviewed with Word's own accept/reject — moved text recognised instead of double-flagged, footnotes and tables handled.

  • The analogous rate table

    Pricing exhibits

    Pricing exhibits in spreadsheets compare as a paged Word redline or a colored Excel review copy, with row/column resynchronization so one changed line item is one changed cell.

Where the difference actually is

Self-hosting and a certificate you can hand over.

  • ✔Nothing leaves your infrastructure. Self-hosted, pure Java, stateless — documents are computed and forgotten, never stored, never sent to a third party. No cloud service, no Office install.
  • ✔A certificate on every redline. SHA-256 fingerprints of the exact drafts compared, recomputable by either side with sha256sum.
  • ✔One-drop re-verification. Drop the redline on the Verify page and it proves the file is unaltered since generation — and, with a configured secret, produced by your server.
  • ✔Verified as it runs. Accepting every change reproduces the later draft; rejecting every change restores the earlier one — checked and stamped on every output.
Said plainly The diff is not the pitch. Any tool can mark up a contract. Only this one hands you a marked-up file that defends itself — and does it without the document ever leaving your building.

Configured for your conventions

Your extraction rules, assertions and profiles.

Any metadata extraction, assertions and profiles are reconfigured per domain and live in editable application.yaml — so applying the tool to contract work is a configuration exercise, not a new product.
