Not sure if this has been asked already, but couldn't find what I need.<p>I have generated hundreds of notes and lists on my phone and tablet containing sparks of ideas in the last 10 years. Some, which were more realistic, I used to make some very successful project. However, now I want to put all these together and just see if I missed something.<p>Is there an app or tool where you can put ideas and use it for brainstorming? Or just analyze, which of these ideas is more feasible or at least realizable?
