Bricknote - A Notes App for indie makers, content creators, and small teams Bricknote started with a YouTube channel. My partner and I run a channel together, so we need one place for video ideas, research, outlines, production notes, and all the small decisions around each video. We used Notion at first. It worked for a while, but our workspace became more complicated than the work itself. It also became too expensive for what we needed, and the product increasingly felt li
