In simple English
This tool records customer interviews on Windows, transcribes both sides in real time, and suggests questions on your phone during the call. It judges your questions against the Mom Test, which means it stops you from fishing for compliments or pitching your idea too early. After the call, it extracts claims into a local database and tracks how your hypotheses are holding up across interviews. You will need an API key for speech-to-text and another for the AI coach, and you must get explicit consent from every person before recording them.
What it is
A Python-based command-line tool for Windows that captures dual-stream audio, transcribes it, and runs a local web server for a phone display and live coaching. It saves transcripts, session metadata, and extracted claims securely on your own machine under git-ignored folders.
What it is good for
Solo founders and product builders running customer discovery interviews who want live reminders to ask about past behaviour instead of hypothetical futures.
- Captures the interviewer and interviewee as two independent audio streams so overlapping speech is handled cleanly.
- Provides live, smartphone-accessible prompts and question suggestions during the call without sharing sensitive notes.
- Organizes past claims and hypotheses locally to track what you have learned across multiple interviews.
- Runs on Windows only because of specific audio loopback library dependencies.
- Requires paid third-party API keys for Soniox speech-to-text and Anthropic or OpenAI-compatible reasoning models.
- Recording conversations carries legal compliance obligations for participant consent and data privacy.
