REIR is a free AI agent that finds the lowest real price for any hotel across booking sites — then keeps watching it and alerts you the moment it drops. No account needed to search. It works for you, not the hotels.

Hey everyone 👋 I built REIR because I kept getting burned by hotel prices. I'd book a room, then find the exact same room cheaper on another site a week later. The same room genuinely costs different amounts across Booking, Agoda, Hotels.com — and the price keeps changing every day. So I made an AI agent that does the annoying part for you: it searches a hotel across the booking sites, finds the lowest real price, and then keeps watching it — pinging you the moment it drops so you can book at the right time or rebook cheaper. It's completely free, no account needed just to search. It's not owned by any hotel or booking platform — it works for you, not them. Would genuinely love your feedback — try it with a hotel you're curious about and tell me what you think. What would make it more useful for how you travel? Thanks for checking it out 🙏

Searched a quick weekend trip and it pulled a price 30 bucks lower than what I had open in another tab. Watching it now to see if the drop alert actually fires overnight.

@ravzasv0o Love this — that’s exactly the moment REIR is built for: catching the gap between what one site shows and what’s actually out there. And yes, the watcher runs overnight, so if it drops you’ll get the alert even while you sleep. Would love to hear if it fires — come back and tell me what happened 🙏 Thanks for giving it a real test, Ravza!

How does it actually get the rates from sites that block scraping, and is the alert piece going to stay free once more people start using it?
