What it means for a UK law firm
A playbook turns the knowledge of senior lawyers into instructions that others can apply consistently. Traditionally a playbook is a document or checklist; in legal AI, a playbook is written as instructions that the AI applies to a document or set of documents.
A playbook used with AI still needs an owner. Someone has to keep the playbook in line with the firm's current positions and the law, and the output of a playbook review still needs checking by a solicitor.
Example
Illustrative scenario
A commercial team's playbook for supplier contracts says to flag any cap on liability below the firm's preferred position, any right for the supplier to vary terms on its own, and any automatic renewal. A trainee runs the playbook on a new contract and the supervising solicitor reviews each flagged clause.
How Chancery handles it
In Chancery, playbooks are written in plain English, the way you would brief a trainee: what to look for, what to flag and who the output is for. You can describe a playbook in a sentence and have Chancery draft it, or start from a built-in playbook and adapt it; see Playbooks. Playbooks also run inside Microsoft Word with Chancery for Word.
