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.

OpenTranscribe is a self-hosted, containerized web application for transcribing and analyzing audio and video files using current AI models. It is built with a FastAPI backend, a Svelte/TypeScript progressive web app frontend, and a Docker-based stack that includes PostgreSQL, Redis/Celery task queues, MinIO object storage, and OpenSearch for full-text indexing. Transcription is handled by WhisperX with the large-v3-turbo model and Faster-Whisper, supporting more than 100 languages, while automatic speaker diarization uses PyAnnote v4 with overlap detection. The project is licensed under AGPL-3.0 and is actively maintained, with v0.4.1 released in April 2026. Beyond transcription, OpenTranscribe provides AI-powered summarization (including BLUF-format and custom JSON schemas), topic extraction, and content analysis through multiple LLM providers such as OpenAI, Claude, vLLM, Ollama, and OpenRouter. Collaboration features include time-stamped comments and annotations, and the platform can automatically import media from local folders, S3, and SMB shares. It also supports a set of cloud ASR providers as alternatives to local transcription, giving teams flexibility between fully local processing and managed services while keeping the application running on their own infrastructure. Pricing varies by plan. Check the official website for current pricing.
