Crackr

We built Crackr for developers and AI engineers who are blocked on one problem and need a senior human right now, not another generic tutorial. Feedback on the positioning and best use cases is welcome.

nice. it would be good to have mentorship program too

I like the positioning around getting unstuck on one specific technical problem instead of offering generic interview prep. Live 1:1 help from senior engineers could be especially valuable for RAG debugging, system design, or LeetCode issues where tutorials don’t cover the exact blocker. Curious whether sessions are matched by specialty, like AI infra, backend, or interview prep.

What's the typical session structure when someone's stuck on an AI/ML problem specifically? LeetCode has a clear template (problem -> constraint -> solution), but AI debugging feels more open-ended - interested in how mentors scope a 1:1 there.

The niche focus here is strong solving real engineering blockers in real time is far more valuable than generic coding advice. Having access to experienced engineers for debugging architecture, AI pipelines, or tricky interview problems could save developers hours of frustration.

Interesting app we want more polished version
