Shortlist CaseMark when court reporters certifying transcripts and producing deposition summaries from recorded proceedings matters most, and WhisperLiveKit when building privacy-first transcription into custom applications via compatible apis matters most. Try them side by side on real calls before deciding — needs vary by team.

CaseMark is an AI-powered legal operating system built for attorneys, law firms, and court-reporting providers. Within its court-reporting product, users upload audio or video recordings of depositions, hearings, and proceedings (up to 8GB per file), then review AI transcript drafts alongside the source media, verify terminology, and certify final transcripts. The platform does not record live proceedings or employ stenographers; it works from existing media files attached to a matter. Beyond transcription review, CaseMark generates structured work product from transcripts and documents, including deposition summaries (page-line, narrative, and analysis formats), proceeding recaps, indices, case summaries, and medical chronologies. Everything is organized around individual matters, with a branded client portal for secure delivery and matter-scoped chat. CaseMark is web-based (app.casemark.com) and exposes services through its case.dev API platform. It is SOC 2 Type II certified and HIPAA compliant, and states it does not use customer data for training. It targets court reporters, litigation teams, and corporate legal departments.

WhisperLiveKit is an open-source, self-hosted toolkit for ultra-low-latency real-time speech-to-text and speaker diarization. Rather than naively running Whisper on each audio chunk, it uses state-of-the-art simultaneous-speech research for intelligent buffering and incremental processing, which preserves transcription quality while streaming results with minimal latency. The project ships a complete backend built on FastAPI with WebSocket support, an OpenAI-compatible REST API, a Deepgram-compatible WebSocket protocol, and a simple, customizable HTML and JavaScript web interface that captures microphone audio and streams it to the server. It supports multiple ASR backends including Whisper variants, Voxtral, and Qwen3-ASR, covers 200+ languages with translation, and includes real-time speaker diarization and voice activity detection to reduce processing overhead. It can handle multiple concurrent users on a single backend and is distributed via PyPI with Docker images for both GPU and CPU. Licensed under Apache 2.0 and actively maintained into 2026, the project explicitly lists meeting transcription, accessibility tooling, and podcast or call transcription with speaker identification among its intended use cases, making it a practical building block for private, on-premise meeting transcription pipelines. Pricing varies by plan. Check the official website for current pricing.
