How Hosiqo compares and tests toolsFinal recommendation

Athreon is a US-based provider of AI-assisted, human-edited speech-to-text transcription, dictation, and virtual scribing services for compliance-heavy industries.
Alter is a native macOS application that records, transcribes, and analyzes meetings directly on the user's Mac without sending a bot into the call. Instead of joining a meeting as a visible participant, Alter captures audio from the system output and microphone, so it works across Zoom, Microsoft Teams, Google Meet, WhatsApp, FaceTime, Skype, Discord, and in-person conversations. Transcription runs through on-device models, with a choice of an optimized Parakeet model for major languages or Whisper for broader language coverage, and speaker identification is performed locally. Because processing happens on the device, recordings and transcripts stay on the Mac and the app can operate without an internet connection. Beyond raw transcripts, Alter generates summaries and action items, lets users chat with their meetings, and connects to tools such as Notion, Slack, Linear, Asana, and Jira. It targets solopreneurs, freelancers, consultants, and other professionals who want private, bot-free meeting capture on macOS. The product is actively developed and operating in 2025 and 2026. Pricing varies by plan. Check the official website for current pricing.

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.
