Idea for people that travel

Hi travellers, I'm a traveller myself that everytime a want a new destination I get into the same problem. Basically, hopefully not only myself, I have a lot of saved videos on tiktok/reels or even youtube with destinations, attractions etc and beside this a lot of other crap and I lose a lot of time just searching for these videos and sorting them. Now I'm a solo developer too and I got an idea, I thought to create a mobile app and while scrolling on different platforms instead of you saving the video you could just send it using the share option in the apps (no need to copy and paste any links) and it automatically saves every video you send and when you enter the app you are going to have every destinations possible sorted and organized by the videos sent, where you are going to have a full map of the city/country with pin points on it for every attractions/restaurant/museum etc from the videos + different routes ideas to see all of them and other places too and maybe a couple of tips and tricks for every destination. Now before I even start this project I wanted to see if someone would even use it, your opinion or suggestions on this, maybe you have another idea too to implement or anything that would be useful and if you were willing to pay for this type of tool and how much and which way (per use? subscription? one time only? etc..)
