Week 1 of MVP launch wrapped up! > Ads running at a 1% CTR (decent!) > 65 🦀 developer sign-ups (solid!) > Only 50% of signups actually tried a challenge (🚨🔴) Users who did try it, loved it. We must have a UX issue of directing signups to their first free challenge. We're pushing an update! LFG

Pro tip when vibe coding: use Claude code for code generation and cursor for cleanup.

Day 13/30 building @rustskill.bsky.social Found some areas to improve on the llm whilst dogfooding the app. #buildinpublic #saas
Ive been dogfooding @rustskill.bsky.social and I have to say the llm is already a very helpful tool. I have it implemented to use the Socratic method. Still needs a fair amount of improvement though as I find it still does not have very accurate questioning threads. #buildinpublic #rustlang #saas
Day 12/30 of building @rustskill.bsky.social Improved llm context ingestion. #buildinpublic #saas
