Agentic File System (AFS) is an autonomous document-work platform that pairs an AI agent with a private, encrypted file workspace. Users drop in folders of documents — contracts, filings, records, and financials — and the agent reads, cross-references, traces, audits, and cites across the entire corpus, returning finished work product as durable files: redlined contracts, cited reports, Bates-stamped exhibit binders, and filled forms. It handles large multi-document corpora that exceed a chatbot's upload limits, and every claim carries an inline citation that deep-links to the exact source passage. A version-controlled workspace memory compounds across sessions, learning the user's formats, rules, and domain. AFS runs as a web application and as a native Mac desktop app over a local folder. It serves practitioners in document-heavy fields — legal, finance, compliance, patent, and medical-records work — and individuals managing consequential personal affairs at professional grade.
