Vernazza - panorama 02

Turn messy recs into a validated, organized trip plan.

A Tripnostic London trip for Jun 13-20 with three validation panels and two side annotations. Red "caught what's closed" points to a Closed panel showing Locanda Locatelli as permanently closed. A stone Limited hours panel shows Columbia Road Flower Market as open Sundays only with a weekly Mon-Sun strip — Sun in teal, the other six days in neutral gray. Amber "what to book ahead" points to a Book before you go panel with London Eye timed tickets, Tower of London summer weekend tickets, and The Ivy Covent Garden dinner reservations.

Validation

Catch closures and things that require booking ahead.

Four London neighborhood cards arranged 2-by-2, each labeled with a day number and listing the actual places you'd hit together: Day 1 Shoreditch (Dishoom, Old Spitalfields Market, Brick Lane, Columbia Road), Day 2 Covent Garden (Royal Opera House, Seven Dials, The Ivy), Day 3 South Bank (Tate Modern, Shakespeare's Globe, Borough Market, London Eye), Day 4 South Kensington (V&A, Natural History Museum, Science Museum).

Optimization

Automatically group your itinerary by neighborhood.

A small Tripnostic card on the left with a "Send to Google Maps · 27" button transforms via a teal flow arrow into a real Google Maps interface on the right showing a private saved list named London — June 2026 with Tower of London, Borough Market, London Eye, Tate Modern, and Dishoom Shoreditch, plus red Google pins clustered across a stylized London map.

Export

Instantly export your itinerary to a Google Maps list.

Tripnostic's "While you're there" list shows three time-bounded London events whose dates fall inside a Jun 13-20 trip window: Trooping the Colour on Jun 13 at Horse Guards Parade (matches your Top Sights picks), Taste of London Jun 17-21 at Regent's Park (matches your Food picks), and A Midsummer Night's Dream on Jun 20 at Shakespeare's Globe (matches your Show picks) — each with a real venue photo, an Add button, and a category-colored match chip.

Recommendations

Events curated to your interests + travel dates.

A messy pile of recommendations from ChatGPT, a Reddit thread, a friend's text, and a blog photo becomes four clean London lists by type — Food, Museums, Top Sights, Nature — each with real venue photo thumbnails and a place count.

How It Works

How is the data accurate when AI itineraries hallucinate?

Tripnostic doesn't generate facts — it checks them.

  • Opening hours come from Google Places (the same source Google itself uses), public holidays from a national calendar, and events from Ticketmaster.
  • Each one is checked against your exact trip dates and destination — by code, not by a language model — and event ideas match the categories already in your trip.
  • When data isn't available, a place is marked "unknown" instead of guessed.
How does the Google Maps export actually work?

A small Chrome extension does the work in your own browser, while you're signed into your own Google account.

  • It creates a private saved list, named after your trip.
  • Each place is added by its exact Google ID — so "Eiffel Tower" lands on the real Eiffel Tower, not a same-name venue somewhere else.
  • Nothing leaves your browser, and the list stays private to your account.
