AI & officers
Policing requires human judgement.
Evidentful is designed to protect it.
Evi conducts interviews. Officers make decisions. That division is not a design constraint — it is the design. Every feature in Evidentful is built around a single principle: AI automates the administrative burden, not the judgement.
AI conducts the witness interview and drafts the witness statement
Witnesses answer interview questions, review drafted statements and make statements amendments
Officers set the interview scope, review evidence and make all decisions
Evi interviews. Officers decide.
Evidentful automates the witness evidence collection workflow. It does not form investigative strategy, decide charging, or replace professional judgement.
Defined responsibilities
Two distinct roles. One coordinated workflow.
Evi collects consistently. Officers review, decide, and remain accountable.
What Evi does
The AI interview engine
Conducts the witness interview
Evi guides witnesses through a structured, PEACE-aligned conversation — at their pace, in their language, on any device.
Adapts questions in real time
Follow-up questions are generated based on what the witness says — probing for relevant detail without leading or suggesting.
Generates a draft MG11 statement
From the completed interview, Evi synthesises a structured MG11 draft — clearly marked as taken by 'Evidentful AI'.
Supports 60+ languages
Interviews and statements are available in over 60 languages without requiring human interpreters for the collection step.
Does not make decisions
Evi does not determine what a witness account means, whether a statement is credible, or what action should follow.
Does not finalise statements
Only the witness can make changes to the drafted statement, maintaining a 'human in the lookup'.
What the officer does
Decision-maker and accountable professional
Initiates every witness contact
No witness receives an Evidentful invite unless an officer has created the incident and authorised the contact. Evi is never autonomous.
Reviews every draft statement
The officer reads the submitted statement to assess the collected evidence.
Retains full legal accountability
Police remain the legal holder of the statement. Evidentful changes how the evidence is collected — not who is responsible for it.
Interprets and acts on the evidence
What a statement means, whether it is credible, and what action it should prompt — these are professional judgements that remain with the officer.
What Evidentful does not do
The things that require a police officer will always require a police officer.
There are aspects of policing that cannot and should not be automated. Evidentful is built with a clear understanding of where those lines are.
Credibility assessment
Whether a witness account is believable, consistent with other evidence, or relevant to the investigation is a professional judgement. Evi does not score credibility — it scores completeness.
Suspect identification
Evidentful does not prompt witnesses to identify photos of individuals, review ID parades, or make any determination about guilt or involvement. All identification procedures remain with officers.
Disclosure decisions
What is disclosed, to whom, and when is a legal decision. Evidentful surfaces complete, timestamped evidence for officers — but never makes or suggests disclosure choices.
Victim support and welfare
Some witnesses still need human officers. Evi is designed for willing, capable witnesses providing evidence — not for vulnerable witnesses or safeguarding conversations.
Complex and sensitive cases
Domestic abuse, sexual offences, and child witness cases require specialist officers and tailored procedures. Evidentful does not replace those processes — it handles low-risk, high volume witness work.
Legal decision making
The decision to caution, arrest, or charge is an officer's decision informed by evidence — not an output of the evidence collection tool. These decisions are out of scope for Evidentful.
“Evidentful frees officers from repeatable evidence administration, so they can spend more time on the human judgement, decision-making, and community protection only police officers can provide.”
— Evidentful Core Philosophy
Transparency & oversight
Every AI action is visible and labelled.
Transparency is not a feature in Evidentful — it is a structural requirement. Officers can always see what the AI did and why it did it.
AI labelling on every draft
Every statement generated by Evi carries a visible 'taken by Evidentful AI' label in the evidence package. There is no ambiguity about what the AI produced versus what the witness stated.
Always onImmutable audit trail
Every action — invite sent, interview completed, draft generated, edit made, statement signed — is recorded in a tamper-evident, append-only log. Nothing can be deleted or altered after the fact.
StatementStreamAlignment with national standards
Built to meet the standards that govern UK policing and AI.
Evidentful is designed with reference to the national frameworks that UK police forces and their procurement teams are required to consider when evaluating AI-enabled tools.
NCSP AI/LLM Cyber Standard v1.1
Evidentful's use of large language models is designed for a narrow policing function: structured witness account capture and draft statement preparation. The system is designed with reference to the Responsible AI Checklist for Policing and the Police Digital Service NCSP Artificial Intelligence Large Language Models Standard, with controls covering information assurance, human review, auditability, data protection, evidential continuity and disclosure readiness.
NCSP alignedNCSP Cyber Security Architectural Principles
Infrastructure design follows the NCSP Cyber Security Architectural Principles, including tenant isolation, role-based access control, and immutable audit logging via StatementStream.
