How Hosiqo compares and tests toolsFinal recommendation
Shortlist Callabo when turning recurring internal team meetings into shareable summaries and action items matters most, and SecureMemo when documenting hr interviews and sensitive consultations containing personal information matters most. Run both through a week of actual calls to see which suits your workflow.

Callabo (콜라보) is an AI meeting assistant developed by Return Zero (리턴제로), a Korean speech-AI company. It automatically records, transcribes, summarizes, and analyzes business meetings for both individuals and enterprise teams, aiming to turn a one-hour meeting into organized notes with a single click and no complex setup. Callabo connects to online meetings on Google Meet, Microsoft Teams, Zoom, and Webex, and also supports recording in-person meetings. After a meeting it produces transcripts, paragraph summaries, key discussion points, and action items with timestamped source quotes, and it can automatically detect the meeting language to handle multilingual conversations. An AI chat feature lets users ask follow-up questions about a meeting beyond the generated insights. The service integrates with workflow tools including Google Calendar, Outlook, Salesforce, Pipedrive, HubSpot, Slack, Microsoft Teams, Zapier, Notion, Confluence, and Linear. For enterprises, Callabo provides meeting access controls, team and member permission management, original-media retention settings, two-factor authentication, IP access restrictions, and audit logs, and it holds ISO/IEC 27001 certification.

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.
