How Hosiqo compares and tests toolsFinal recommendation
Shortlist Alter when freelancers and consultants privately capturing client calls without a visible bot matters most, and CallMiner when compliance and risk teams flagging regulatory or fraud issues across all customer calls matters most. Run both through a week of actual calls to see which suits your workflow.

CallMiner is an enterprise conversation intelligence platform that transcribes and analyzes voice and digital customer interactions for sentiment, intent, and compliance.
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.

CallMiner is an enterprise speech and conversation analytics platform, built around its Eureka product, that captures and analyzes customer interactions across voice and digital channels. It records and transcribes calls into text, then applies acoustic and linguistic AI to surface sentiment, emotion, intent, and behavioral signals — quantifying frustration, effort, satisfaction, and confidence rather than sampling a fraction of conversations. Designed for contact centers and large enterprises, it spans modules for analysis, automated agent scoring and coaching, real-time guidance during live calls, automated redaction of sensitive data, multilingual translation, and interactive dashboards. CallMiner ingests voice, chat, email, surveys, social media, and screen recordings, applying scoring models to isolate compliance risks, fraud, quality issues, and sales outcomes. It also includes generative and agentic AI features such as automatic category creation, contact summarization, and natural-language discovery. The platform is used across healthcare, finance, retail, insurance, and BPO sectors, and was named a leader in The Forrester Wave: Conversation Intelligence Solutions for Contact Centers, Q2 2025.
