I recently made a bot that scapes the local apartment listings every five minutes, filters by price and area, and then sends me the new ones in the form of Telegram messages with the basic details, a GIF of the photos (scaled to mobile size), and a map widget.
Getting push notifications with the new apartments is really great, and I'll definitely be making more Telegram bots in the future...
You could charge for this if you expanded it out to other areas and websites. Might have to work with the data providers to ensure you're not breaking their TOS by scraping their websites, though.
