Redline

A cited document-review workspace for commercial leases and contract review. Redline extracts the facts, runs deterministic lease checks, keeps advisory notes separate, and pins every finding to the source text.

§01The workLive system

Drop in a lease or contract. Redline reads it, runs the right review profile, and keeps every issue pinned to the clause that caused it.

Redline
macOS app · CLI · MCP

A second read on your lease or contract before you sign.

Redline reviewing a Master Services Agreement: a 'don't sign yet' verdict lists two problems (an auto-renewal opt-out window that already passed, and a cross-reference to a section that does not exist), each linked to the exact clause on the page.
Redline's start screen: the app icon over the line 'Catch lease problems before you sign,' with a 'Check a lease' button.

Extract

The document is converted into cited facts, with the source quote and page kept beside the extracted value.

Profile

The general lease profile checks the broad review surface, while the lease-math profile stays available for the original financial reconciliation lane.

03

Separate

Rule findings stay separate from advisory context, so a negotiated note or thread does not masquerade as a deterministic verdict.

deterministic · advisory
04

Decide

Each issue stays tied to the clause that caused it, with uncertainty surfaced instead of hidden.

§03What I builtPieces that compound

What's actually doing the checking.

General lease review.

The default profile looks beyond one math defect: financials, dates, comparison terms, clause coverage, renewal windows, additional-rent visibility, assignment/sublease consent, and termination-right asymmetry.

financials · dates · clauses

Advisory notes without blurred verdicts.

Redline can compare the document against notes, threads, or deal terms, while keeping advisory risk separate from deterministic lease checks.

notes · threads · deal terms

One engine, three doors.

The macOS app, command line, and MCP surface run the same review engine, so the product behaves consistently whether it is used manually or inside an agent workflow.

Mac app · CLI · MCP

Honest contract support.

Non-lease contracts can be reviewed with context and citations. The page does not claim deterministic profiles that have not been built.

§04The checksDeterministic lease checks

The rules the verdict is built on. Each one runs over extracted facts and keeps its evidence attached.

Selected checks11 lease checks · evidence on every fail
  1. Financials reconcile. Schedules, totals, escalations, and comparison terms have to line up.
  2. Dates cohere. Commencement, expiry, term, renewal, and notice windows have to agree.
  3. Clauses are covered. Missing or asymmetric rights are surfaced instead of buried in prose.
  4. Additional rent stays visible. CAM and other pass-through obligations are treated as review-critical.
  5. Context stays labeled. Deal notes and thread context inform advisory risk without becoming rule verdicts.
  6. Uncertainty is explicit. A check that cannot run is reported, not passed.

The CLI and library. Deterministic lease findings over extracted facts, with structured output and a CI-usable exit code.

The rule engine

The review profile keeps rule-based findings separate from advisory notes, so the app does not blur arithmetic, citations, and judgment.
