Shortlist Braina when transcribing recorded meetings and interviews into text or subtitles matters most, and Koji when building personas and validating early product concepts at scale matters most. Try them side by side on real calls before deciding — needs vary by team.

AI-native customer research platform whose AI interviewer runs voice and text discovery conversations at scale, then synthesizes themes automatically.
Braina (short for "Brain Artificial") is a Windows desktop AI assistant and speech-to-text application developed by Brainasoft. For meeting-related work, it transcribes pre-recorded audio and video files (WAV, MP3, M4A, MP4) into text, handling content such as meetings, interviews, lectures, and broadcasts. Transcription runs locally on the user's computer, supports multiple speakers without voice training, and can output plain text, text with timestamps, and subtitle formats (SRT and WebVTT). It also offers live voice dictation into any application across many languages, plus voice commands for controlling the PC. Beyond transcription, Braina provides an interface to local and cloud large language models, note-taking with persistent memory, reminders, and document chat. It runs primarily on Windows, with companion iOS and Android apps that can remotely control a connected PC over Wi-Fi. It is aimed at professionals, students, and researchers who want desktop dictation and offline file transcription rather than an automated bot that joins live meetings.

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.
