Validate your ChatGPT or Gemini travel itinerary

The problem

An AI itinerary can read beautifully while missing practical details: places that moved or closed, hours that do not match your dates, sights that need tickets booked ahead, or stops scattered across the city with no regard for transit.

How TripSapien handles it

• Review the whole itinerary in one pass instead of checking each stop by hand. TripSapien checks matched places with available data; ambiguous, unmatched, or missing-data stops stay visible for confirmation with the official source. Free — no ads, no sign-up. Backed by a vetted catalog of more than 380,000 places and growing.
• Paste the AI itinerary as-is. TripSapien extracts candidate place names and tries to match them to known places.
• For matched stops, it shows available opening hours for your dates, closure signals, and booking guidance. Ambiguous names, unmatched suggestions, and missing-hours entries remain visible for review.
• Matched places can be regrouped by neighborhood so you can inspect whether the AI’s day order sends you back and forth across town.

Questions

Why does an AI itinerary need checking?

Even when an AI assistant can browse, its itinerary may not reflect live or date-specific venue information. Opening hours, closures, ticketing, and whether a place still exists should be checked before the trip.

Do I need to reformat the itinerary first?

No. Paste common formats such as day headings, bullets, or prose. TripSapien attempts to extract the suggested place names and keeps uncertain results visible.

Is TripSapien free?

Yes. You can paste an itinerary and run the core match-and-review workflow at no cost.
