HeyHaddock vs bestflights.ai

HeyHaddock was an AI-first travel app built to make trip planning faster, more personal, and easier to share with friends. Users could shape itineraries around their own tastes, invite friends to collaborate, and get recommendations for local cafes, restaurants, and things to do in a new city.

The product leaned on an AI layer that generated events and travel insights based on your preferences. That meant suggestions beyond generic tourist lists, like a specific coffee shop or a lesser-known viewpoint that matched how you like to explore.

HeyHaddock shut down on September 1, 2025. The team reported more than 6,000 trips planned through the app before closing the service. The site now serves as a shutdown notice with contact details for former users.

bestflights.ai is a travel flight search interface built around plain-language requests instead of multi-field booking forms. The homepage shows example prompts like booking Denver on a specific date, finding mile-based fares to Paris, comparing the fastest route to Mexico City, or leaving New York after 3pm, which signals the product targets open-ended trip constraints in one sentence.

Compared with traditional OTAs that make you pick airports, dates, and cabin class in separate filters, bestflights.ai foregrounds conversational queries on the landing page. That layout suggests the search layer is meant to interpret budget, loyalty miles, speed, and departure windows from natural phrasing rather than making travelers translate those needs into dropdowns first.

The live site is still a slim early-access landing page: most paths such as /pricing and /features return 404, and the Early Access button routes to marco.app, which shares a Marco privacy policy link from the bestflights.ai footer. Frequent flyers and flexible-date travelers are the obvious audience, but anyone evaluating the tool today should expect a demo-style homepage rather than a full booking checkout on bestflights.ai itself.
