1.AI Vendor Contract Review With Claude
This is essentially the most pressing use case on this checklist in 2026, and the one with the least present infrastructure at most firms.
Every firm is now signing agreements with AI distributors at a tempo that in-house authorized groups weren’t constructed for. OpenAI, Anthropic, GitHub Copilot, Harvey, Glean, Notion AI: these arrive on a Tuesday with a “can legal turn this by EOD” request connected. The enterprise needs to maneuver quick, however authorized has by no means reviewed something fairly like them.
The motive they’re tougher than normal SaaS agreements: the IP and information phrases are genuinely new territory. A typical SaaS contract is about entry and availability. An AI vendor settlement is about what the mannequin is allowed to do along with your information, who owns what the mannequin generates, and who’s liable when the output is unsuitable. Does the seller practice in your inputs? Who owns the outputs Claude generates when your crew makes use of it? What is the indemnification cap for AI-generated errors that find yourself in a consumer deliverable? What are the info residency phrases? What occurs to your information at termination?
These usually are not hypothetical. Colorado’s Artificial Intelligence Act went into impact in February 2026. California’s AI Transparency Act went into impact January 2026. The contractual panorama round AI instruments is shifting actually quick and most firms are signing these agreements with no playbook.
What Claude does
Drop the seller MSA and ToS into your Cowork workspace folder, then run:
/review-contract vendor-agreement.pdf
For AI vendor agreements particularly, add context after the command:
/review-contract vendor-agreement.pdf
Focus particularly on:
– Data coaching rights: can the seller practice fashions on our inputs or outputs?
– Output possession: who owns content material the mannequin generates?
– Liability for hallucinations or errors in mannequin output
– Data residency and retention at termination
– IP indemnification masking the seller’s coaching corpus
We are a monetary providers firm working below GDPR. Flag any provision that conflicts with our information processing necessities.
You also can cross-reference your present vendor relationship earlier than the evaluate:
/vendor-check [Vendor Name]
Honest caveat
Claude flags what the contract says. It doesn’t know your danger tolerance, your relationship with this vendor, or whether or not the enterprise will settle for the deal delays that include negotiating each flagged time period. That judgment is yours. If a flag requires data of native legislation you aren’t sure about, get specialist recommendation earlier than concluding it’s acceptable.

2.Regulatory Compliance Scanning for In-House Legal Teams
DORA went reside on January 17, 2025. Article 30 requires all contracts between EU monetary entities and ICT third-party service suppliers to incorporate 9 necessary baseline clauses: an entire description of providers, information location necessities, information safety provisions, entry and restoration rights, full SLA descriptions for important features, incident reporting obligations, audit rights, termination rights with minimal discover intervals, and exit technique provisions.
The similar problem recurs each time a big regulation is issued. DORA created an train. The EU AI Act’s obligations for deployers of high-risk AI programs are phasing in by way of 2026 and can create one other. US state AI legal guidelines are multiplying. This is now a everlasting characteristic of the regulatory surroundings.
What Claude does
Share your contract library folder with Cowork. Then run:
/compliance-check DORA Article 30 necessities throughout all contracts in /vendor-agreements/
For every contract, Claude checks whether or not every of the 9 Article 30(2) baseline clauses is current, partially current, or absent. For contracts supporting important or essential features, it checks the extra Article 30(3) necessities: detailed SLAs, enterprise continuity provisions, audit rights, and exit technique phrases. It flags contracts which can be clearly compliant, these with gaps, and people the place the supply exists however is materially inadequate (an audit rights clause restricted to as soon as per yr with no discover, for instance).
The output is a niche register: one row per contract, columns for every clause class, and a separate flagged part for contracts requiring pressing remediation. What would take a junior lawyer three weeks to provide manually takes a day.
For GDPR, the EU AI Act, CPRA, or every other framework, alter the command:
/compliance-check EU AI Act deployer obligations throughout all information processing agreements
The construction is similar. Swap the regulatory framework within the command.

3.Contract Obligations Monitoring With Claude
Contracts get signed and filed. The obligations inside them don’t disappear.
SLAs your organization should meet. Renewal discover home windows that require 60 or 90 days’ advance motion. Change-of-control clauses that set off on an acquisition. Audit rights that have to be exercised inside a window. Payment milestones tied to deliverables. All of those hold operating on their very own timeline whereas the signed contract sits in a shared drive folder someplace.
The WorldCC has reported that organizations lose as much as 9% of annual contract worth by way of poor contract administration. The commonest model of that loss in apply: a SaaS vendor auto-renews a six-figure annual contract as a result of no one caught the 90-day discover window buried in clause 12.4. The enterprise needed to exit. Nobody was watching.
What Claude does
Run a standing transient that surfaces upcoming deadlines earlier than they turn into issues:
/transient vendor renewals and obligations due within the subsequent 90 days
Claude scans your contract library and produces a structured report organized by urgency: contracts with renewal discover home windows closing within the subsequent 30, 60, and 90 days; excellent SLA obligations; any change-of-control or task restrictions on lively agreements; and audit rights with expiring home windows. It flags which of them require motion and what that motion is.
For a particular vendor:
/vendor-check Acme Corp – full obligations abstract

4.M&A Due Diligence Using the Claude Legal Plugin
A typical mid-market M&A transaction includes reviewing upward of 10,000 doc pages throughout a due diligence timeline of six to 12 weeks, in line with information from a number of digital information room suppliers. A 2024 Bayes Business School examine discovered that common due diligence timelines elevated 64% during the last decade, rising from 124 days in 2013 to 203 days in 2023, pushed by rising regulatory calls for, ESG scrutiny, and doc quantity.
What Claude does
Organize information room paperwork by class in a shared Cowork folder. For every class, run:
/review-contract [folder: /data-room/material-contracts/]
We are the customer in an acquisition. Flag all the following:
– Change-of-control provisions: does the clause require consent, enable termination, or have one other impact on the transaction?
– Assignment restrictions
– Any contract with a time period extending past 3 years from right this moment
– Non-standard or uncommon provisions
– Missing displays or schedules referenced however not included
For a broader danger image throughout the info room:
/legal-risk-assessment full information room evaluate for acquisition of [Target Company]
Identify: prime 5 authorized dangers by class, all change-of-control provisions throughout any contract, any litigation or regulatory matter disclosed, and any IP not clearly owned by the goal firm. Produce a abstract desk organized by danger stage.
After class critiques are full:
/transient M&A diligence memo – materials contracts part
Based on the contract critiques accomplished, draft the fabric contracts part of the diligence memo. Structure: Summary of Findings, Material Issues, Open Items, and Recommended Actions. Flag any deal-critical points that require a closing situation or negotiation.
Claude produces a well-organized first draft of every diligence memo part. The supervising lawyer critiques it for context Claude doesn’t have (deal dynamics, business norms, purchaser’s danger urge for food), provides substance on something requiring authorized judgment, and finalizes. Extraction and structuring work that might take an affiliate two days takes a couple of hours.
Honest caveat
Claude doesn’t know what’s regular in your business, what the customer’s strategic danger tolerance is, or whether or not a particular situation is deal-breaking given the deal context. It additionally can not assess what just isn’t within the information room, which is usually the place the true issues disguise. Senior lawyer evaluate earlier than something goes to the consumer just isn’t non-obligatory.

5.Contract Drafting From Your Legal Playbook
Drafting from scratch produces generic output. Every Harvey and Spellbook article leads with “AI can draft contracts” and the drafts look skilled till you understand they don’t replicate your indemnification cap, your normal limitation of legal responsibility carve-outs, or your information processing positions.
The workflow that really works: drafting from your individual requirements.
Once your playbook is in your authorized.native.md file, Claude is aware of your most popular positions. Tell it what deal you have to doc:
Draft a Master Services Agreement for the next:
Counterparty: [Vendor Name]
Services: [brief description]
Fees: [amount and structure]
Term: 12 months with computerized annual renewal
Governing legislation: New York
Non-standard positions agreed in negotiation: limitation of legal responsibility agreed at 24 months of charges as a substitute of our normal 12 months
Use our playbook for all different positions. For any clause the place the playbook specifies a fallback, use the popular place except I’ve indicated in any other case above. Flag any clause the place the deal specifics require a judgment name the playbook doesn’t clearly tackle.
Claude produces a primary draft MSA reflecting your normal positions. You evaluate the flagged clauses, make the calls Claude couldn’t make from the playbook alone, and ship the draft to the counterparty. A contract that might take two to 3 hours to draft takes thirty to forty-five minutes.
The similar workflow applies to SOWs, amendments, and facet letters. The precept is similar in every case: your language, your positions, Claude doing the meeting.
Honest caveat
The draft is simply nearly as good because the playbook. If your playbook is imprecise on a clause kind, the draft will probably be imprecise on it too. When counterparty counsel sends again a marked-up settlement in an uncommon jurisdiction elevating a novel query and it’s a authorized evaluation job, not a drafting one.

Where In-House Legal Teams Should Start
Pick one workflow. Not all 5. One workflow, finished effectively and refined over a couple of iterations, saves extra time than 5 workflows run as soon as and deserted. The plugin learns your playbook higher the extra you utilize it. The first evaluate calibrates towards your requirements, and the tenth one runs in half the time.
The ratio of judgment to paper has not modified in a long time of in-house authorized work. This is the way you begin altering it.
Cheers!
