Locul

Every second brain on this list asks you to do the work: capture the note, tag it, file it, keep it current, forever. Locul asks you to do nothing, because you already did the work. It reads the places your thinking already lives, the markdown and PDFs sitting in your folders, your Notion docs and specs, your Obsidian vault, the dictations you talk through Wispr Flow, Willow Voice, and Contextli, and your LinkedIn back catalogue plus whatever you post next, with more sources on the way. Everything is read in place, originals untouched, and distilled into one memory of what you actually know: your facts, decisions, people, products, and projects.
