Make Interviews Count: AI-assisted investigative interviewing

Evidano is an AI-powered qualitative data analysis platform that enables secure, auditable transcription and thematic analysis for AI-assisted investigative interviewing.

AI can speed intake, transcription, and synthesis, but investigative interviews are reconstructive and AI can contaminate memory unless used with evidence-first controls.

• Run small, auditable pilots (suggested n=20–50) that measure recall accuracy and false detail rates before wider deployment.
• Use secure, human-in-loop workflows: automated transcription and thematic analysis followed by human validation preserves traceability and reduces automation bias.
• Follow a 7-step pilot that includes PII redaction, timestamped transcripts, spot checks against audio, and an auditable export for legal review.

Investigative interviews are reconstructive and easily distorted, and The Conversation warns that AI tools can both help and contaminate accounts.

Investigative interviews are not neutral recordings of memory, they are reconstructive and easily distorted by leading questions, media and post-event information; The Conversation authors warn that AI tools (chatbots, real-time prompts, avatars) can both help and contaminate accounts.

• Payoff: practical controls and an evidence-first pilot let teams automate transcription and synthesis without degrading recall or introducing automation bias.
• Quick win: use secure, auditable AI-assisted workflows (transcription, thematic and cross-segment analysis, human validation) to reduce manual hours while preserving court-admissible traceability.

AI can be applied to intake, transcription, real-time prompts, and avatar-based training, but each application offers efficiency gains and introduces specific failure modes.

Where AI can be applied: initial large-scale intake (conversational agents), automated transcription, real-time interviewer prompts, and avatar-based training simulations, each offering efficiency gains but introducing specific failure modes.

• Use cases: scale intake, speed transcription, surface themes across many transcripts, simulate difficult interviews for training.
• Observed risks: memory contamination from AI elaboration, automation bias (over-trusting model outputs), faithfulness/factual errors, and unknown effects on vulnerable witnesses (children, trauma survivors, cognitively impaired).
• Unknowns: how AI-mediated contamination propagates through multi-stage investigations and whether small LLM errors compound into courtroom-impacting mistakes.

Follow a contained 7-step pilot to test efficiency gains while protecting evidence quality and measuring contamination risks.

Follow this short pilot to test gains while protecting evidence quality:

• 1) Define success metrics (recall accuracy, false detail rate, time-to-synthesis).
• 2) Ingest a restrained corpus (n=20–50 interviews) into Evidano with PII redaction enabled (train custom dictionary first).
• 3) Auto-transcribe and timestamp; spot-check against raw audio for faithfulness.
• 4) Run thematic and cross-segment analyses to identify common details and divergence by witness type.
• 5) Use AI chat to generate follow-up question suggestions; require a human reviewer to approve before use.
• 6) Measure pre/post exposure recall accuracy in a controlled sub-sample to detect contamination.
• 7) Produce an auditable report (clickable quotes, codebook, exportable visuals) for legal review and policy sign-off.

The Conversation (26 June 2026) argues that AI can speed investigative workflows only if used under strict, evidence-first controls.

The Conversation (26 June 2026) underscores a simple proposition: AI can speed investigative workflows, but only if used under strict, evidence-first controls. Researchers and teams should pilot small, measurable workflows that combine Evidano secure transcription, thematic and cross-segment analyses, and human-in-loop validation to capture efficiency without sacrificing reliability.

• Next step: run the 7-step pilot above on a contained corpus and produce an auditable report for policy review.
