When Axel is not lower on a flight, it shows the airline's fare all the same.\n\nAsk for a route and dates: Axel returns live fares with the Axel price, the airline's own fare for the same flights, and the difference. Ask for a hotel by city, neighborhood, landmark or name: Axel returns live rates with the Axel total beside the public rate when it beats one, the room, the cancellation terms, and a link to review the stay.\n\nBooking happens on helloaxel.com. New customers continue with just an email, the price is checked again, and you confirm before the booking is made. Your ticket or reservation sits in the airline's or hotel's own system under your name.\n\nWithout this app, ChatGPT can still reach Axel through its web search. Ask it to check helloaxel.com for your route or hotel, and it can read Axel's live prices on the website, where every search page shows the Axel price beside the public one and the same link to book. This app skips the web search and runs the search inside the chat.\n\nAxel is built by Gordian Software, Inc., a Y Combinator company in the Seattle area.",
