I built a two-way AI voice interview simulator for developers
I built DevPrep.app because I kept failing technical interviews even when I knew the material. The problem wasn't knowledge it was that I'd never actually practised saying my answers out loud under pressure.
Most prep tools make you type. Some let you speak into them.
But DevPrep.app actually talks back.
The AI asks you a question out loud, listens to your spoken answer, gives feedback, and asks follow-up questions just like a real technical interviewer would. It's a genuine two-way voice conversation, not just speech-to-text into a text box.
Also includes 500+ flashcards across Azure, C#, React, TypeScript, Docker, Kubernetes, Python, SQL, Terraform and more, with progress tracking and review mode.
Free tier available. Would love any feedback.

Separate the score into technical correctness and interview delivery. A candidate can know the answer but ramble, miss the question, or collapse under a follow-up. Track structure, concision, clarification, and response to challenge beside correctness. Improvement across repeated versions of the same question is stronger evidence than a single AI score.
I like that you're practicing the skill people are actually evaluated on.
Knowing an answer and communicating it clearly under pressure are two different abilities, and most interview prep tools only train the first.
Thanks Aryan that was what I was going for, knowing the answer is one thing, conveying is another.
I'm glad it resonated.
Your reply made me think about one implication of training that skill which I'd rather explain with your product in mind than as a generic observation.
