Look4U: AI-assisted travel for Romania, from Bucharest
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.

Welcome to Lounge, Ovidiu. Itinerary correctness seems to split into hard checks like opening hours, drive times and whether stops exist, and softer ones like pacing. Are you validating those against a places dataset such as OSM inside the LangGraph loop, or after generation?
