A personal knowledge base is where what you learn stops evaporating. This collection gathers AFFiNE's free PKB templates — second-brain setups, zettelkasten systems, reading vaults, and visual knowledge maps — for building a system that compounds.
Each template gives the system a skeleton: capture inboxes, note structures, linking conventions, and review rhythms. Duplicate one, feed it what you read and learn, and let links between pages grow the structure a folder tree never could.
Pick the system that matches how you think below.
A structured collection of your own notes — from reading, work, and study — organized so you can find and connect ideas later. The difference from a notes folder is deliberate structure: consistent capture, linking, and review.
A second brain (PARA-style) organizes by actionability — projects and areas; a zettelkasten organizes by ideas and links. Choose the first if your notes serve projects, the second if they serve thinking. Plenty of people run both.
Capture less, link more, and schedule a weekly review. A small base you revisit beats a huge one you do not — the templates here build the review step in so the system stays alive.
