Evidence transcription with word-level timestamps
Interrogations, 911 calls, jail calls, bodycam, witness interviews — discovery is mostly audio and video, and none of it is useful until it's text. Evidence Copilot transcribes everything with speaker labels and word-level timestamps, into the same searchable workspace where the rest of the case already lives.

Generic transcription wasn't built for evidence
Consumer transcription tools miss specialized terms, mislabel speakers, and hand you a text file with no link back to the recording — which makes every quote a chore to verify and every clip a manual scrubbing session.
Court reporting services are accurate but slow and expensive, and they still leave the transcript disconnected from the rest of the case file.
How it works
- 1
Upload or email the media
Web upload up to 2 GB per file, or forward recordings to the case's intake email address.
- 2
Diarized transcription
Speaker labels with word-level timestamps. Rename a speaker once — officer, defendant, dispatcher — and it updates everywhere.
- 3
Search and cite
Full-text search across all transcripts in the case. Any line links straight to its moment in the recording.
- 4
Redact what must go
Pick spoken words in the transcript and that exact audio span is muted for discovery turnover — word timings make the cut precise.
What you get
Word-level timing
The basis for precise clips, precise audio redaction, and transcript sync across multiple cameras.
Speaker diarization + renaming
Diarization separates speakers; one rename propagates across every segment.
911 and jail calls
Phone audio transcribes into the same searchable corpus — increasingly the most consequential evidence in the file.
Per-segment review
Edit or flag any transcript segment; corrections are tracked against the original machine output.
Everything downstream works
Transcripts feed search, AI answers, auto-compare, exhibit packs, and case briefs — one pipeline, no copy-paste.
Built for
- Attorneys reviewing interrogation and call evidence
- PD offices processing bulk discovery media
- Clerks producing hearing exhibits
Frequently asked questions
Can you transcribe jail calls and 911 audio?
Yes — phone-quality audio is a standard input. Transcripts get the same speaker labels, timestamps, and search as bodycam video, and they join the same case-wide corpus.
How accurate is AI transcription for legal evidence?
Clean audio transcribes very well; cross-talk, radio traffic, and degraded recordings are harder everywhere. That's why every transcript is editable per segment, timestamps let you verify any quote in seconds, and the machine output is always preserved for comparison.
Is there a human review step?
Your team is the review step: transcripts are editable, and anything an AI produces in the workspace is marked for human review. We never present machine output as certified.
What formats can I upload?
Standard video and audio formats up to 2 GB per file, plus documents and images. Email intake accepts attachments too.
