Pick behavioral, coding or system design, set the role, seniority, company and job description, and get tailored questions. Answer by typing, or out loud to a voice interviewer that asks follow-ups.
Each answer gets a score, a rubric breakdown for that interview type, strengths, improvements and a model answer you can compare against.
When a practice session ends, download your feedback as a Markdown report or delete it. After a real interview, a session report sums up the questions and what to work on next.
Built for interviews, and works for any call. Everything is tuned for live, high-pressure conversations where a faster, clearer answer helps.

Run behavioral, coding or system design mock interviews tailored to the job description, typed or out loud with a voice interviewer. Every answer gets scored feedback and a model answer, and you can download the full report when you finish. How practice works
Connect GitHub and Co-Help reads the relevant files from your repositories, so technical answers about your own projects are grounded in your real code.
After a live session, get a short report from your local transcript: the questions asked, key points, and specific suggestions for next time.
Your interview profile, conversations, transcripts, and knowledge base live on your machine — never on our servers. For your account we keep only the basics: your name, email, a hashed password, and your plan. AI requests pass through, get answered, and are discarded; we log only request metadata (time, model, size) — never the content (AI providers may keep request data for a limited period under their API policies — see Privacy §5).
