What Lixir is
Lixir is a voice-based AI interviewer for software engineers preparing for coding interviews. Practice takes place in a live editor: the interviewer follows code as it is written, asks follow-up questions, and can offer a nudge when someone is stuck. Users can select silent proctor, guided, or pair partner mode. Code can be run in JavaScript and TypeScript, while problem discussions can use Python, Java, or Go. After each session, reports score coding, problem solving, communication, and collaboration, with session evidence and suggested next steps. Users can provide a job description and practice from a resume; Pro adds resume-based personalization. The Free plan costs nothing and includes one practice interview, three coding challenges, real-time coaching, and a performance report after each session. Pro costs $20 a month and includes unlimited practice interviews and coding challenges, scored reports, and resume-based personalization; the pricing note also says From $29. Lixir runs in a modern browser and requires a microphone and stable internet connection, with no installation. It is intended for users aged 18 or older.
