Use case
Expert witness prep at case-volume scale
BrassTranscripts Legal lets trial attorneys bulk-transcribe the full set of expert witness interviews, technical depositions, and consultation recordings — then use AI prompts to generate summaries and surface the testimony actually worth focusing on at direct and cross.
Create an accountExpert testimony is the densest content in the case
Expert witness recordings concentrate the most technically demanding content in any case — terminology, methodology, opposing-expert critique — and traditionally require the most attorney hours to extract. BrassTranscripts Legal flips that ratio: minutes of processing per hour of expert testimony, then AI-assisted summarization across the full corpus.
A complex case might involve 6 experts, each with 4–8 hours of recorded testimony across direct interview, deposition, and consultation. That's 24–48 hours of dense audio. Bulk-transcribed at $4.00 per file in the 50–99 tier, the entire corpus costs under $50 to convert into searchable text — leaving the attorney's time for the analysis only the attorney can do.
AI prompts narrow the corpus to what matters
BrassTranscripts Legal's AI prompt toolkit includes summarization, key facts extraction, and contradiction analysis prompts that work across multiple expert transcripts at once — letting trial counsel surface the 5% of testimony that's case-relevant from the 95% that's setup, methodology, and routine cross-reference.
- Executive Summary Generator — condense expert testimony into key positions and supporting evidence
- Strategic Insights Extractor — identify case-relevant statements and decisions
- Contradiction Analyzer — surface inconsistencies within or across expert transcripts
- Key Facts Extractor — pull case-relevant facts (citations, dates, methods, conclusions) into structured form
- Cross-Examination Prep — generate cross-examination outlines based on expert positions and testimony gaps

Technical terminology and accuracy expectations
BrassTranscripts Legal handles common legal and technical terminology, but specialized domains (medical-legal, patent claims construction, financial methodology) require attorney review and correction of working transcripts before relying on them for substantive case work.
The recommended workflow: AI-transcribe the full expert corpus for working copies and AI-assisted analysis. Spot-check transcripts against audio for terms specific to the expert's field. Use AI prompts to summarize and identify focal testimony. For the specific recordings being filed or entered into evidence, order certified transcripts from a court reporter.
Frequently asked questions
How do I handle expert depositions versus expert interviews?
Both are recorded audio or video and process the same way through BrassTranscripts Legal. Expert depositions are typically the more formal record (sometimes also covered by certified court reporters); expert interviews and consultations may exist only as your firm's recording. AI transcription handles the volume; you decide which recordings need certified transcripts based on whether they'll be entered into evidence.
How accurate is AI on technical expert terminology?
BrassTranscripts Legal handles common technical terminology at professional-grade accuracy for clear audio. For specialized domains (medical-legal, patent claims construction, financial methodology, engineering forensics), spot-check transcripts against audio for terms specific to the expert's field — particularly product names, methodology names, and statistical terms.
Can AI prompts handle multiple expert transcripts at once?
Yes. The Executive Summary Generator, Strategic Insights Extractor, and Contradiction Analyzer prompts all work across multiple transcripts when concatenated as input. For complex cases with 6+ experts, run prompts on each expert's transcripts separately, then run a synthesis prompt across the per-expert outputs to surface cross-expert patterns.
What's the cost for a typical expert workup?
A complex case with 6 experts × 4-8 hours each = 24-48 hours of recordings, typically split across deposition / interview / consultation files. At the 50-99 file tier ($4.00 per file), the entire expert corpus costs under $50 to convert to searchable text. Compared to attorney hourly rates spent on manual review, the cost is negligible.
Should I keep the original audio files?
Yes. AI transcripts are working copies — for any expert testimony being formally cited or relied on, the audio remains the source of truth. Audio files are deleted from BrassTranscripts servers 24 hours after upload, so download originals to your matter file before that window closes if you need long-term retention.
