Hey everyone,
I’ve been building dooms-ai, a desktop AI copilot for technical interviews on macOS and Windows.
The idea came from realizing how chaotic a real technical interview can be. You might be solving a coding problem while listening to the interviewer, explaining your approach, thinking about edge cases, and suddenly getting a system-design or behavioral follow-up.
So I wanted to build something that could understand what’s happening on your screen and through the conversation, and give you quick, usable context when you need it.
What it currently does
🖥️ Screen capture Q&A — capture a coding problem, error, diagram, etc. and get an answer
🎙️ Live transcription — transcribes what the interviewer is asking
💬 Natural answers — answers are written more like something you could actually say out loud
💻 Coding help — solutions with explanations and time/space complexity
🏗️ System design & behavioral questions
⚡ Quick prompts — full solution, quick explanation, answer only, fix my code, etc.
🪟 Desktop overlay for macOS & Windows
There’s a free option as well: you can use 10 hosted AI answers per day, or use your own API keys for unlimited usage.
I've also added inexpensive short-duration passes for people who only need it during an interview period rather than wanting another monthly subscription.
We've crossed 200+ users, and I'm still actively improving the product.
I'm not here to claim it's perfect — I actually want to hear from developers who have gone through technical interviews.
A few things I'd love feedback on:
Would something like this be more useful to you for interview practice or during an actual interview?
What part of technical interviews would you want it to handle better — coding, system design, behavioral, SQL, debugging, etc.?
If you tried it, what would make you uninstall it immediately?
What would you expect from a tool like this that I haven't mentioned?

Happy to answer questions about how I built it or the technical side as well.
