Second brain app
Sofie Wiki is a second brain with an AI that captures, organizes, and links your notes for you. You think out loud, the wiki takes care of the structure. Free for you, upgrade for your team.
The second brain method is simple in theory: capture everything you learn, organize it, and retrieve it when you need it. The hard part is the organize step. Most second brain apps hand you a blank note and a tagging system, then leave you to do the filing. You start strong, fall behind, and end up with a graveyard of unlinked notes.
Sofie Wiki removes the part everyone gives up on. You chat with an AI assistant, it creates or updates the right page, cross-links related entries, and versions the change. Your second brain stays current without you sitting down to organize it on a Sunday.
The reading experience is familiar: a Wikipedia-style interface with table of contents, search, categories, and full revision history. You do not need to learn a new tool to retrieve your own thoughts. You ask, you read, you get on with your day. And when you bring it to your team, the same wiki scales up to a shared workspace.
Start free. No credit card required. Upgrade when the wiki is part of your day.
