Learn Croatian from A1 to C1 with structured lessons, speaking practice, and AI correction.
u/Formal_Diver9067 · Reddit
I built a full A1 to C1 Croatian course because none of the big language apps teach it I started building Govoriti because I wanted a proper way to learn Croatian and kept running into the same problem: the big apps just do not teach it. Duolingo, Babbel, Rosetta Stone, Busuu, all skip Croatian. There are a few smaller options, but most either stop fairly early or feel more like content libraries than actual courses.

Practice debugging real code across multiple languages with an AI coach that guides without giving answers.

Project helping new graduates prepare for AI Assisted Interviews A lot of big tech companies have started adopting an interview style where students debug code and are allowed to use AI to help with this process. This interview is to figure out how the applicant uses AI within their coding process. There isn’t much to prepare for this format of interview so I created a platform to this. Any feedback is appreciated! https://aicodingprep.com/ submitted by /u/ApprehensiveCall406
