How Hosiqo compares and tests toolsFinal recommendation
Shortlist 123 Notetaker AI when teams-centric organizations that do not have or want copilot licenses matters most, and Callabo when logging sales and customer meetings into crm tools like salesforce or hubspot matters most. Run both through a week of actual calls to see which suits your workflow.

123 Notetaker AI is an AI meeting notes and transcription app for Microsoft Teams, built by BlueSky Apps. It runs entirely inside the Teams interface and does not depend on Microsoft Copilot, giving teams an independent option for capturing meetings. During a call, participants can open the app from the meeting window to follow AI-powered transcription that appears in real time in the Teams app sidebar. After the meeting ends, 123 Notetaker AI generates a summary and emails the meeting notes, while transcripts and notes are stored in the user's BlueSky account for later reference. Because it is installed from the Microsoft commercial marketplace and operates within Teams rather than as a browser overlay or external bot, it fits organizations that want note-taking contained in their existing Teams workflow. BlueSky Apps offers a family of conferencing add-ons across Teams, Zoom, and Google Meet, and provides a free plan with paid upgrades for additional capacity and features. The app is currently listed and operating in 2025-2026, and is documented in the company's help center and several third-party Teams tool roundups. Pricing varies by plan.
