Show HN: AI feedback on system design diagrams

https://system-design-6m8.pages.dev/
2•gpe•3h ago
Hey everyone,

I made a tool to practice System Design for technical interviews.

I am currently practicing System Design interviews and honestly this is not my forte. Since I am also trying to keep my programming skills sharp and get more products to show off in my portfolio, I thought maybe I could implement a tool that would help people practice this kind of interview as well.

It seems most of people preparing for such interviews are using:

* videos of recorded practice interviews * books (especially Designing Data-Intensive Applications) * mock interviews with FAANG engineers ($$)

The goal of this tool is to provide a whiteboard to the user, then use AI (Gemini) to assess the user submission with respect to some metadata about the problem that guide the LLM about what a good solution should look like.

Not selling anything, there is no paywall, no login, not asking for email etc. For now, I'm just trying to see if someone else finds this useful, and if this idea got legs. If it doesn't I would open-source it (code needs some cleaning).

Hope someone finds this useful: https://system-design-6m8.pages.dev/

Any feedback is appreciated!

PS: There are a few bugs that I am working on, noticeably the anchoring of edges can be buggy at times but this is only a display issue.

PPS: Right now, it's using Gemini free tier.

I wish! unfortunately companies are still requiring us to clear this kind of challenge. Maybe not for long?
cranberryturkey•3h ago
is the diagram exportable in any kind of standard UML format? That would be sick and add a feature to have AI generate the diagram. That would be far more useful.

the UML format is a good idea, I will have a look.
