How Hosiqo compares and tests toolsFinal recommendation
Shortlist Callabo when turning recurring internal team meetings into shareable summaries and action items matters most, and TwinMind when users who prefer a bot-free, privacy-conscious notetaker over tools that join the meeting matters most. Try them side by side on real calls before deciding — needs vary by team.

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. Mobile apps are available for both iOS and Android. Pricing varies by plan. Check the official website for current pricing.

TwinMind is an AI meeting assistant delivered as a Chrome browser extension and companion mobile app that captures, transcribes, and summarizes conversations from video calls and in-person meetings. The Chrome extension works alongside Google Meet, Zoom, and Microsoft Teams to produce real-time transcripts and then generate structured notes and action items after the call. Rather than sending a separate bot participant into the meeting, TwinMind transcribes the audio playing on the user's device, so there is no visible 'recording bot' announcement. The company emphasizes a privacy-first design: the product states that audio is not stored and that only text transcripts are kept, with data saved locally and optional encrypted cloud backup. TwinMind supports a large set of languages and lets users query their past conversations through an AI chat interface, positioning itself as a personal 'second brain' for recall. It markets a single experience spanning desktop browser and phone so meetings, voice notes, and ambient conversations can be captured in one place. The product is actively maintained and operating in 2025-2026. Pricing varies by plan. Check the official website for current pricing.
