Built for Legal Professionals

Deposition & Hearing Ready

Handles the structured cadence of legal proceedings — witness testimony, attorney objections, sidebar discussions, and formal Q&A exchanges.

Privileged Communications Stay Private

No audio is uploaded to any server. Attorney-client conversations, witness interviews, and case strategy discussions never leave your device — eliminating third-party data breach risk.

Legal Terminology Recognition

OpenAI Whisper recognizes common legal vocabulary — statutes, case citations, Latin phrases like habeas corpus and res judicata, and standard procedural language.

Timestamps for Cross-Reference

Every transcript segment includes precise timestamps. Cross-reference testimony with video recordings, identify key moments for trial preparation, and create time-coded annotations.

Export for Case Files

Export as TXT for case memos, SRT for video evidence captioning, or JSON for integration with legal document management systems. Use the format your workflow requires.

Multilingual Transcription

Transcribe witness statements and client interviews in 100+ languages. Essential for immigration law, international arbitration, and cases involving non-English-speaking parties.

Frequently Asked Questions

Can this replace a certified court reporter?
No. Whisper Web provides an excellent rough draft for internal use, but it is not a certified transcription service. For official court records, certified depositions, or filings that require a certified transcript, you still need a court reporter. Whisper Web is ideal for working transcripts, case preparation, and internal documentation.
How does this protect attorney-client privilege?
Unlike cloud-based transcription services, Whisper Web processes all audio locally in your browser. No audio or text is transmitted to any server. This eliminates the risk of third-party exposure and helps maintain the confidentiality required for privileged communications.
How accurate is it with legal terminology?
Whisper recognizes common legal terms, statutory language, and procedural vocabulary well. Latin legal phrases, widely-known case names, and standard courtroom language are generally accurate. We recommend reviewing proper nouns, docket numbers, and specific statutory citations before relying on the transcript.
Can I transcribe a multi-hour deposition?
Yes. Most modern devices can handle recordings up to 2-3 hours. For very long depositions, consider uploading in segments. A 2-hour deposition typically takes 15-25 minutes to transcribe, depending on your device's processing power and WebGPU availability.
Is the transcript timestamped for cross-referencing with video?
Yes. Export as SRT or VTT to get precise timestamps aligned with your recording. This is particularly useful for trial preparation — you can quickly locate the exact moment a witness made a key statement.
Does any data leave my browser?
No. Zero data leaves your browser. The AI model runs entirely on your device using WebAssembly and WebGPU. There are no servers, no API calls, and no data collection. This is critical for legal work where even metadata exposure could compromise case strategy.
