How Hosiqo compares and tests toolsFinal recommendation
Shortlist Callabo when turning recurring internal team meetings into shareable summaries and action items matters most, and Némos when capturing spoken thoughts as voice memos and converting them to searchable, formatted notes 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. Mobile apps are available for both iOS and Android. Pricing varies by plan. Check the official website for current pricing.

Némos is a personal knowledge management ("second brain") app for the Apple ecosystem that captures and automatically organizes many content types, including voice memos that it records and transcribes on-device. Rather than joining video calls as a bot, it captures audio directly from the iPhone or Apple Watch and converts speech to text locally using Apple Intelligence Foundation Models, so data stays on the device. Transcribed audio becomes fully searchable, and recordings can be turned into formats such as bullet points, summaries, meeting notes, emails, or journal entries. Beyond voice, Némos handles screenshots with OCR, links, PDFs, notes, photos, and more, naming and filing them automatically without manual tagging. It runs on iPhone and iPad (with Apple Watch recording, Siri commands, and Chrome, Safari, and Firefox extensions), and offers two-way sync with Apple Reminders, Calendar, Notes, Photos, Files, Maps, and iCloud. It is aimed at students, researchers, writers, and professionals who want private, low-effort capture of voice and other notes. As of mid-2026 it is in private beta.
