How Hosiqo compares and tests toolsFinal recommendation
Shortlist Athreon when transcribing medical dictation and clinical documentation in hipaa-compliant workflows matters most, and Whisperstream when transcribing imported audio recordings privately on-device matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

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.

Whisperstream is a downloadable Windows desktop application from Lanreal Technologies Inc. that converts speech to text using push-to-talk dictation. Transcription runs entirely locally on the user's PC via the NVIDIA Parakeet model, so audio is never uploaded to the cloud and no account is tied to the user's voice. It works across any application without add-ins or setup, inserting dictated text directly into tools such as Outlook, Gmail, Slack, VS Code, browsers, and Claude Code. Beyond live dictation, it can import and transcribe existing audio recordings, and it keeps a searchable transcript history with audio replay, encrypted on the device. Additional features include AI cleanup that tidies spoken input, a custom vocabulary for names, jargon, and acronyms, per-app custom AI prompts, support for 25 languages, global keyboard shortcuts, and full offline operation. It requires Windows 10 or 11 (64-bit) with at least 8GB RAM. It targets professionals and privacy-conscious knowledge workers who want fast, local voice input rather than typing.
