How Hosiqo compares and tests toolsFinal recommendation
Shortlist Athreon when transcribing medical dictation and clinical documentation in hipaa-compliant workflows matters most, and OpenTranscribe when collaborative review of transcripts with time-stamped annotations matters most. Try them side by side on real calls before deciding — needs vary by team.

Self-hosted, containerized web app for transcribing and analyzing audio/video with WhisperX, speaker diarization, search, and collaboration.
Athreon is a US-based company, operating since 1988, that provides speech-to-text transcription, dictation, and virtual medical scribing services. Rather than purely self-serve software, it uses a hybrid workflow that pairs AI transcription with professional human editors to convert audio and video recordings into accurate, editable, and searchable text, including multi-speaker conversations and focus-group recordings. Audio can be captured several ways: the Athreon mobile dictation app for iOS and Android, telephone dictation requiring no extra equipment, supported PC and handheld recorders (Philips, Olympus, Nuance), and secure file upload to its platform. The service offers EHR and API integrations and connects with existing dictation systems and workflow portals such as InQuiry, Axis Online, and NetScribe. It emphasizes security and compliance, including HIPAA and CJIS support, SSL encryption, GovCloud hosting for law enforcement, and background-checked, US-based staff. Athreon is aimed at organizations in healthcare, legal, law enforcement, insurance, finance, research, government, and media that need certified, court-ready documentation. The company also offers separate cybersecurity services.

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.
