Built for developers, by developers
We're passionate about empowering developers to succeed in their technical interviews. Our software is designed to provide real-time insights and support during your interview preparation, helping you to perform at your best when it matters most.
We won't name names.. but a lot of software out there charge crazy prices for a subscription, and we think that is unfair. We provide lifetime access to the software, and you can use your own API Keys with any provider you choose.
Developer First
We know the pain points of coding interviews because we have been there. Designed to address the real challenges developers face during their interview preparation.
No Subscriptions
We believe in providing value without barriers. Get lifetime access to the software, and use your own API Keys with any provider you choose. No crazy subscriptions.
Almost undetectable
We try to be as undetectable as possible, but we can not guarantee that. We are committed to continuously improving our software to stay ahead of detection methods.
Continuously Improving
We are dedicated to constantly enhancing our software, incorporating user feedback, and staying ahead of industry trends to provide the best experience for developers.
Why Noeth?
Named after Emmy Noether — the mathematician who solved the hardest problems of her era while the room kept looking the other way.

Built for People Who Want an Edge
From interview prep to code review, Noeth helps developers think faster, explain better, and solve with more confidence.
James Whitfield
Software Engineer — London, UK“Landed a £95k offer at a fintech in London after three rounds. I had been paying £60/month for another tool and honestly getting less. Noeth was £12 once and did more. Not even close.”
Priya Nair
CS Graduate — Manchester, UK“I was bleeding money on subscriptions — one at $49/mo, another at $30/mo. Neither of them let me use my own API key. Noeth was $15 once and I never looked back. Got my first dev role two months later.”
Daniel Kim
Backend Engineer — Toronto, CA“Interview Coder wanted $299 a month. I used it for one month and cancelled. Found Noeth the same week and it replaced it completely. I bring my own Gemini key so the AI cost is basically nothing.”
Sofia Martinez
Frontend Developer — Berlin, DE“The code review caught things I would have said out loud and regretted. It flagged an O(n²) loop I was about to walk the interviewer through. Saved me there for sure.”
Noah Chen
New Grad — San Francisco, US“Got an offer from a FAANG-adjacent company. The complexity breakdowns and flowchart visualisations helped me actually understand what I was saying instead of just reciting steps.”
Ava Thompson
Full Stack Developer — Dublin, IE“I was on Cluely before this. $40/month and no way to use my own key. Every interview I was burning through their credits. Switched to Noeth and I'm using Ollama locally now. Free inference.”
Liam Carter
Mid-Level Engineer — Amsterdam, NL“Screenshot the problem, read the reasoning, walk the interviewer through it like I thought of it myself. That workflow is just clean. Went from freezing up to actually enjoying the process.”
Aisha Okafor
Machine Learning Engineer — Lagos → London“Six-figure role in London. I prepared for two weeks using Noeth every day. It helped me structure my thinking under pressure, not just spit out code. The difference was obvious.”
Marcus Reed
Self-Taught Developer — Birmingham, UK“No CS degree, no bootcamp, just grind. Noeth made hard problems feel learnable. I got a junior role at a startup paying £42k and I genuinely don't think I get there without this tool.”
