I've previously had a Pocket subscription and switched to Bear Pro to track bookmarks but neither is perfect. I would be happy to offer feedback each week as you build out your app.
I actually started building something like this too, I think it's a pretty common project idea. I ended up finding raindrop.io which I really really like. Maybe you can check it out. The free version is good enough for me at the moment but I'm considering upgrading.
I use Pocket to save stuff I'm gonna read later, then if it's a really good resource I put it in Raindrop and categorise + tag it. It also has moodboard if you wanna save images as references.
Hi Metabeard! If you're interested in having a chat about your experience with other tools and possibly becoming an early adopter of my app you can shoot me an email at charles@charlesthecoder.dev :)
I also read the Mom Test! I'm almost done with the book it's been a great resource to learn from! My telegram is https://t.me/celoubao we can schedule a call or direct message from there if you want
