Hey, happy Sunday.
This week in legal AI: Anthropic has put Claude directly inside Microsoft Word, Simmons & Simmons has welcomed its first AI law interns, and Legora has hired Jude Law.
Let's dig in.
The Best Practice Podcast
Dillon is building something truly unique in the Legal AI world, an AI powered matter-management system for law firms.
In all the analysis and start-ups I've seen, this is something deeper than just a chat-interface. This is worth a listen if you want to learn about what the next generation of Legal AI for law firms will look like.

Anthropic puts Claude inside Word - and skips the legal AI middleman
This week Anthropic released Claude for Word as a public beta, available as a native sidebar add-in for Microsoft Word on Mac and Windows via the Microsoft AppSource marketplace.
On paper, it's another entry in Anthropic's slow march across the Office suite: Excel arrived in October 2025, PowerPoint followed in February 2026, and Word now completes the set.
The detail
The first example use case listed on Anthropic's own product page is "Legal contract review" with suggested prompts that read like a junior lawyer's brief: summarise the commercial terms, flag provisions that deviate from market-standard position ranked by severity, make the indemnification mutual, work through the reviewer comments as tracked changes.
The pricing gate is deliberate too — the beta is restricted to Claude Team and Enterprise subscribers, not individual Pro users.
This follows the February 2026 release of Anthropic's legal plugin for Claude Cowork, which triggered Thomson Reuters to fall 16%, RELX fell 14%, and Wolters Kluwer fell 13% over just a few days.
Harvey CEO Winston Weinberg acknowledged that "Anthropic remains one of the models our customers benefit from using in Harvey”.
Why it matters
The bull case for Harvey's $11bn and Legora's $5.5bn valuations, or any legal AI vendor, has always rested on two assumptions:
(1) that lawyers would pay a premium for a legal-specific interface sitting on top of a foundation model.
(2) that the foundation model providers themselves wouldn't come downstream. Anthropic has now falsified the second assumption in the most direct way possible — by putting its product inside the application where lawyers already spend their working day.
Legal AI vendors will need to articulate a sharper answer than "better UX" or "legal-specific workflows" — because Anthropic's skills feature means those workflows are increasingly buildable in-house.
Worth Knowing
Simmons & Simmons runs the UK's first dedicated AI law internship - Simmons welcomed eight students to its inaugural AI law internship in London, a two-week programme running until 24 April covering both tech-focused and legal AI roles within the firm's AI team. It's open to penultimate and final-year undergraduates, postgraduates and graduates, with standout performers flagged for future roles.
Legora opens San Francisco and Toronto offices - Legora announced the opening of new offices in San Francisco and Toronto alongside a major engineering hub at its existing New York office. Toronto is Legora's first Canadian office, following its acquisition of Walter, and the company now plans to grow to more than 300 employees across North America by the end of 2026. This follows the $550m Series D round that valued the company at $5.55bn last month.
Q1 2026 AI sanctions hit a record - US courts imposed at least $145,000 in sanctions in the first three months of 2026 for AI-fabricated citations, with the total climbing from $5,000 in January to over $139,000 in March alone.
Funding & New Partnerships
Legora hires Jude Law - Legora launched a global brand campaign starring Jude Law under the tagline "Law just got more attractive.
The two-minute film was directed by SNL veteran Rhys Thomas and shot by Academy Award-winning cinematographer Hoyte van Hoyteman.
It's the second major brand move for Legora in a week, following a multi-year partnership with the New York Yankees and their slugger Aaron Judge announced.
Freshfields puts 5,000 professionals on Google Gemini. One year into its partnership with Google Cloud, Freshfields reports that more than 5,000 of its professionals are now using AI tools built on Google's Gemini models, integrated across proprietary platforms including its Dynamic Due Diligence tool and its case management system.
Over 2,100 team members regularly use NotebookLM Enterprise with custom managed encryption keys, and an internal AI Academy is delivered by 260 "AI Champions." It's one of the more specific Magic Circle disclosures we've had — real numbers against named tools, a multi-platform architecture rather than a single-vendor bet, and structured training underneath it.

What a sheepdog trial can teach an AI agent
Researchers at the Georgia Institute of Technology spent hours watching footage of competitive sheepdog trials — the kind that have been running since the 1870s — to study how a handler and a dog manage to steer a small flock across a field.
They then applied what they learned to computer simulations of robot swarms, autonomous vehicles and AI agents — networked systems where many machines have to coordinate under noisy, uncertain conditions. The study ran as the cover feature of Science Advances in March.
Why it matters
The wider lesson is one legal tech will recognise. As one of the researchers put it, "Dogs can steer the direction, but they can't hold that decision indefinitely, so timing matters."
Anyone building or deploying AI agents in professional services is wrestling with exactly that problem — how to direct a swarm of quasi-autonomous systems towards an outcome without over-steering them. It turns out a Border Collie figured out the answer about 150 years ago.
