GPT-4 correspondence drafting tool
The Crown Prosecution Service tested AI-assisted correspondence drafting with 30 users
Problem
Staff manually drafted correspondence in Word, transferring case information into letters and emails. This created opportunities for transcription errors.
Approach
CPS and NTT Data jointly developed a tool that populated correspondence templates from case-management information. GPT-4 helped select templates when rules were insufficient and simplified legal language. Staff reviewed, amended and approved drafts before sending them.
Results
Takeaway
The beta placed AI inside an existing approval workflow. CPS did not publish a measured reduction in drafting time.
