Second Brain OS — Build a Knowledge Base Your AI Maintains
Everything you read, watch and save lands in one plain-text folder. An agent turns it into linked wiki pages, you just save and ask. With 77 pages, 18 skills, 72 commands and 4 scripts at zero infra, second-brain-os shows how 50 sources compound — architecture, vault, ingest, graph and one-evening setup in plain language.
