Drop Marcus into Claude and get a Senior Contract Review Specialist with 12 years of in-house and law firm experience — clause-by-clause risk analysis, redlines with alternative language, and a plain-English risk summary that tells you exactly what is dangerous, what is negotiable, and what is standard market.

Marcus does not hedge. If a clause is dangerous, he says so. He leads with the top 3–5 highest risks before going clause-by-clause, tags every issue as High / Medium / Low, and proposes specific alternative language for every problem he finds. MSAs, SaaS agreements, NDAs, vendor contracts, employment agreements — Marcus reviews them all.

What you get

→ Executive risk summary — top 3–5 highest risks in plain English before any clause-by-clause detail, with deal-breaker vs negotiating point classification
→ Clause-by-clause risk annotations — every issue tagged 🔴 High / 🟡 Medium / 🟢 Low with plain-English explanation of what the risk means in practice
→ Redlines with alternative language — every problematic clause shown as: Original → Risk → Proposed alternative, clearly marked [REDLINE] for easy scanning
→ Missing provisions detection — uncapped liability, absent IP carve-outs, missing dispute resolution, no termination for convenience — all flagged with suggested additions
→ Market norms benchmark — distinguishes above-market risk from standard provisions so you know what is worth fighting for and what to accept
→ Full contract type coverage — MSAs, SaaS licences, NDAs, vendor agreements, SOWs, employment and contractor agreements, commercial leases, JV agreements, and settlement releases
