Hi, I'm Ovidiu, building Look4U, an AI travel platform for Romania

Hi everyone, I'm Ovidiu Dumitru, founder and CEO of Look4U, based in Bucharest. I work independently on an AI-assisted travel platform focused on Romania. It combines editorial discovery with geographically grounded itineraries, for people planning trips in the country.
On the build side, I use Claude, ChatGPT, Grok, Google AI Studio and Codex day to day, with LangGraph and gpt-oss for the AI logic and Supabase as the backend. I'm still working out how to keep itineraries trustworthy and tied to real geography, rather than plausible-sounding but wrong.
What I'd love from this community: feedback from anyone who has built grounded, location-aware agents with LangGraph, especially on how you evaluate whether an itinerary is actually correct. Happy to compare notes.
