SemanticPDF

The candidate, SemanticPDF, explicitly states its core functionality as "SemanticPDF: Drag, Drop, Semantic Search - SemanticPDF is a simple, privacy-focused application that makes it easy to upload a PDF file and perform a semantic search on contents." This directly matches the 'semantic-search' must-have feature. Additionally, the candidate emphasizes its "privacy-focused" nature, stating "All files, text, and embeddings are stored locally in your browser, keeping your data private by processing the data with the FastAPI backend but not storing the files or embeddings in any database," which aligns with the 'privacy-controls' must-have feature. However, it is limited to PDF files and does not offer the broader file management capabilities, conversational AI for actions beyond search, or automated sorting rules as described in the concept.
