AI-native customer research platform whose AI interviewer runs voice and text discovery conversations at scale, then synthesizes themes automatically.
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. Check the official website for current pricing.

Koji is an AI-native customer research platform built around an AI interviewer that conducts natural, in-depth conversations with research participants at scale, removing the need to schedule and moderate live discovery calls one at a time. Teams describe what they want to learn, and an AI research agent helps define goals and generate an interview guide. The AI then runs the interviews asynchronously in either a text chat or spoken voice format, asking adaptive follow-up questions and probing for depth as a human moderator would. Each completed conversation is analyzed automatically for key moments and sentiment, and findings are synthesized across all interviews into study-wide reports surfacing themes, patterns, and recommendations, with every insight traceable back to the participant quote that supports it rather than presented as a black-box summary. Koji is used for exploratory work such as discovery, persona development, and market strategy, as well as concept and messaging testing. The product is operated from Amsterdam with EU data residency and GDPR compliance, offers a freemium entry point, and integrates with tools including Claude, ChatGPT, Cursor, and Notion via an MCP server. Pricing varies by plan. Check the official website for current pricing.
