Best for A company that wants hotel booking without a membership fee, and can treat the savings line as an average.
Engine, at engine.com, is a business-travel booking platform. On October 27, 2026 the homepage says companies book hotels, flights, cars, and meeting spaces, and that the same booking can run from ChatGPT, Claude, Gemini, or any MCP client. It says Engine's AI resolves 60% of chats and that a person answers in about 20 seconds, 24/7. The page cites 40,000+ businesses and 2 million travelers. The pricing page says Engine is free to join and use: no membership fee, no contract, and no minimum spend. Hotels pay a commission. A disclaimer says a 26% average hotel saving is based on 2025 bookings and is not a guarantee. The pricing FAQ says the platform lists 1,000,000+ properties and that flights and rental cars can be booked there too. Flex is a per-booking flexibility option. FlexPro, on its own page the same day, is $299 a month or $2,999 a year and returns eligible hotel cancellations, until noon on check-in day, as a one-year travel credit rather than cash. That page says coverage is not every booking, and it says it was last updated September 2, 2026. The pages we read do not name an app store.
On October 27, 2026 engine.com/pricing says the platform is free to join: no membership fee, no contract, and no minimum spend. FlexPro is $299 a month or $2,999 a year. You still pay for the stay.
