Drop PDFs, YouTube links, documents — Stellavault auto-organizes into a linked wiki. Claude accesses everything via MCP. 1. Ingest anything (PDF, YouTube transcript, DOCX, XLSX, URL) 2. Auto-compile into wiki with concepts + backlinks 3. Claude searches, asks, and drafts from your vault Vault files never modified. 100% local-first. Next: P2P Knowledge Federation — connect vaults across users. Only embeddings shared, never original text. Free, MIT, open source.
