How Hosiqo compares and tests toolsFinal recommendation
Shortlist Alter when freelancers and consultants privately capturing client calls without a visible bot matters most, and Voicegain when building telephony voice bots and call analytics matters most. Try them side by side on real calls before deciding — needs vary by team.

Speech-to-text and ASR platform with developer APIs plus a private LLM-powered meeting notetaker.
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.

Voicegain is a speech recognition company that offers both speech-to-text APIs for developers and a packaged meeting assistant called Transcribe. Its ASR engine supports batch transcription of recorded files and real-time streaming for live audio, and it can be deployed in the cloud, in a customer's virtual private cloud, or on-premises, which appeals to organizations with strict data-control or privacy requirements. On the developer side, Voicegain provides speech-to-text, speech-analytics, and telephony-bot APIs that can transcribe audio and analyze it for sentiment, named entities, topics, and intent. Its meeting product, Transcribe, is described as a private, LLM-powered meeting notetaker that captures audio from video-meeting browser tabs and uploaded recordings, integrates with Zoom, Microsoft Teams, and Google Meet, and automatically identifies topics and highlights from a conversation. A Windows desktop app supports Zoom local recordings. Because Voicegain spans both an underlying ASR platform and an end-user meeting tool, it suits teams that want either to build on its APIs or to use a ready meeting notetaker with flexible deployment and a focus on keeping data private. Pricing varies by plan. Check the official website for current pricing.
