How Hosiqo compares and tests toolsFinal recommendation
Shortlist Alter when freelancers and consultants privately capturing client calls without a visible bot matters most, and SecureMemo when documenting hr interviews and sensitive consultations containing personal information matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Japanese on-premise and offline AI meeting-minutes tool from Nishika for confidential, security-sensitive organizations.
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.

SecureMemo is an AI meeting-minutes application developed by Nishika, Inc., a Japanese company, and is designed for organizations that handle confidential or sensitive meetings and cannot use cloud-based services. It runs in on-premise, closed-network, or fully offline environments, processing audio entirely within the customer's own infrastructure so that voice data never leaves the organization to an external cloud. SecureMemo is powered by Nishika's in-house speech recognition AI called "shirushi," which the company states maintains high recognition accuracy even with background noise or overlapping speech, and can transcribe audio in roughly 100 languages including Japanese, English, Chinese, and Thai. The product offers five core capabilities: accurate voice recognition, automatic speaker identification, automatic meeting-minutes generation that organizes decisions and key points, translation across about 100 languages, and custom terminology support through word registration for specialized vocabulary. The workflow follows a simple three-step process of transcription, speaker recognition, and summarization. It is offered in standalone, USB-dongle, and client-server deployment models, with case studies spanning police, government agencies, universities, manufacturers, and financial institutions. A two-week free trial of the standalone version is available. Pricing varies by plan. Check the official website for current pricing.
