How Hosiqo compares and tests toolsFinal recommendation
Shortlist Athreon when transcribing medical dictation and clinical documentation in hipaa-compliant workflows matters most, and Celeste AI when companies needing pay-as-you-go transcription without fixed subscriptions matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Brazilian Portuguese-focused AI voice and transcription platform offering on-demand transcription plus a meeting assistant and AI notes, with credit-based and subscription plans.
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.
