Roam Research

The best note taking/thinking tool I've ever used. Bi directional links is where it's at.

Brilliantly linked writing experience. Anything can be a link or tag.

Smart way to create, organize and access notes using intuitive tagging rather than relying on a folder system that invariably fails to show the connections between related notes

Using this for one of my writing projects and I've got to say it's definitely one of the better note-taking apps out there.

I'm not in love with it yet, but I'm using it for a personal CRM and notes. It's 10x better than Evernote or Notion for book notes because you can effortlessly connect ideas, highlights, and thoughts among books.

Roam is a very interesting way to collaborate your notes. I use ROAM as a record of recent articles/books/podcasts I have read and I love checking back on my bi-directional links as I add content.

Graphs, graphs, and more graphs.

Roam is the only note-taking app out there that helps augment your mind ability to discover relationships in your knowledge to create new knowledge.

I've just started to use Roam Research. So far, the product seems much better suited to connecting thoughts and ideas across dimensions, such as time and domain, than standard note-taking tools like Evernote (that I continue to use).
