Casey (casey.legal) is a UK-based legal AI platform (Legal108 AI Ltd) that helps law firms turn their expertise into AI-powered products for clients. Formerly known as 108 Future AI and 108 AI. Allows firms to feed in precedents and playbooks for AI-powered reviews. Also operates Caseway.ai for legal research and document automation. Connected to UK law firms Fieldfisher, Mills & Reeve, and HCR Law via Fabric Ventures accelerator program — this appears to be an incubator relationship, not confirmed client deployment. Very early stage (~42 LinkedIn followers). Single r/Lawyertalk mention confirms a user was testing the tool. No confirmed production deployment found. No pricing, no security documentation, no independent press coverage. Product output format unclear — ‘productize expertise’ is too vague for practitioner evaluation. Precedent ingestion mechanism undocumented despite being the core value proposition. No security documentation for a platform handling firm’s most confidential work product — critical blocker. One of the thinnest evidence bases in this batch.

Workflows
Based on practitioner evidence, Casey (Legal AI) is used in these workflows:
What practitioners struggle with
Real frustrations from legal professionals — the problems Casey (Legal AI) addresses (or should address). Sourced from practitioner reviews, Reddit threads, and case studies.
Legal research costs $400-600/hour in associate time and takes hours of manual digging — searching Westlaw/Lexis, reading irrelevant results, synthesizing case law. Clients increasingly refuse to pay for research hours on invoices. AI can compress a 4-hour research memo into 20 minutes, but most firms have no approved tool
BigLaw firm with 1,000+ lawyers has decades of work product locked in DMS folders — the precedent brief the partner drafted 3 years ago is unfindable, institutional knowledge walks out the door when partners leave, and junior associates waste hours recreating work that already exists somewhere in the system
