Hey everyone — I’m Rushil, the creator of CodeWiser.
I built CodeWiser after noticing something troubling: junior developers and interns under me were copy-pasting from ChatGPT without truly understanding what the code was doing. Worse, some of that unchecked, AI-generated code was making its way into pull requests, and PR comments were also being addressed by LLMs. It wasn’t just about bad habits — it was about the loss of foundational thinking, creativity, and design tradeoffs.
That sparked the idea: what if we could use LLMs not as a shortcut, but as a coach?
CodeWiser is built around that philosophy. It turns LLMs into a learning partner — one that tests, adapts, and reinforces understanding. Through auto-generated quizzes, contextual feedback, and performance analytics, it helps developers build actual insight, not just output.
Who is it for?
• Educational Institutions: Professors can use it to create adaptive homework, personalized exams, and track student progress — all mapped to each student’s current understanding, with paced learning.
• Interview Prep: Get AI-generated LeetCode-style questions — including original variations with unseen edge cases — tailored to your weak spots.
• Teams working on legacy code: Developers can quiz themselves on poorly understood codebases to build confidence and clarity faster.
• Self-learners & bootcamp grads: Perfect for reinforcing key concepts and preventing over-reliance on autocompletion or AI answers.
What’s the challenge?
• Avoiding over-simplification — many quiz systems reward rote memory. We’re focused on conceptual depth and code reasoning.
• Generating fair but novel quizzes — our LLM has to balance originality with alignment to real-world dev expectations.
• Measuring progress accurately — we have built a proficiency engine that goes beyond right/wrong and adapts difficulty based on response patterns and speed.
Would love your thoughts on:
• How do you see LLMs fitting into learning, not just productivity?
• What are the biggest struggles you’ve seen with devs learning through AI?
Thanks for checking out CodeWiser
Happy to answer anything — feedback, features you’d like to see, or even critiques!
interesting concept, LLMs should be used to take away mundane tasks, but using then to create and teach base line coding and ensure that the LLMs are being trained through responsible and clear inputs is essential. this is a step in the right direction
@vinit_shah5 This is just the start of a lot more exciting things to come in this space!
Congats on your launch Rushill, I have noticed the same with entry level devs. Congrats on the luanch. Looks like we are launch day twins or something anyway, wishing you all the best.
@afwcole Thank you, I see a lot of potential for this means of education. Paced learning is extremely important to make sure that your top performers aren't the only ones with solid learning outcomes. Wishing you the very best as well.
Currently on a landing page and theme update, appreciate the patience <3
Custom questions really enhance learning! 😄
@shenjun There is a lot more to come - very, very soon :)
Super stuff. 👍
Good practical
