PDF, Markdown, CSV, code and other text files are parsed 100% locally in your browser. Relevant excerpts are retrieved per message and injected into the chat context. If a long document needs the ~22 MB search model, WKO AI asks before downloading it. Scanned or password-protected PDFs cannot be read.
