Your knowledge is everywhere.
That's the problem.

Notion, sticky notes, bookmarks, local files, GitHub.

// the builder

Built from
real frustration.

Every developer has this moment: you fixed that exact bug six weeks ago. You know you wrote it down. But where? Notion? A Gist? That Slack thread you'll never find again?

I lived this daily. I even built a Swift prototype for macOS to solve it, but it was stuck on one machine. I needed something that worked anywhere. DevNote is the web version of that idea.
