ValidaTrip - paste your ChatGPT itinerary, get back only the places that are actually open

Last fall I planned a trip mostly with ChatGPT. Tuesday morning, cafe #1: closed Tuesdays. Cafe #2: permanently closed since 2022 (GPT didn't know). Cafe #3: dinner only. Repeat for 4 days.

So I built https://www.validatrip.com.

You paste recs from anywhere - a ChatGPT itinerary, a Reddit thread, a blog post, a friend's text - and it:

• Pulls the actual places out, dedupes them, sorts by type

• Checks each one against your travel dates (weekly closures, permanent closures, holidays, seasonal stuff)

• Groups your days by neighborhood so you're not zigzagging

• Surfaces festivals and public holidays that overlap your trip

Free, no account, no email. Works on a phone.

Stack: Next.js, Supabase, Google Places, plus a small validation layer that stitches a few APIs together.

Solo project. The hardest part was getting "paste anything" to reliably pull out the actual places - would love feedback on that flow specifically if anyone has a chaotic itinerary to throw at it.
