Fenn
PaidPrivate AI that knows your files.
Fenn is a private file intelligence system for macOS that indexes the content inside your local files and lets you search, chat, and organize them without sending data to the cloud. It runs entirely on Apple Silicon, understands PDFs, Office documents, images, screenshots, audio, video, and code files, and opens results at the exact page, slide, timestamp, or frame. Users ask questions in plain language, refine answers in a chat thread, and jump straight to the source moments inside their files.
What is it
Fenn is an on-device AI file search and knowledge layer for macOS that turns your local folders into a searchable, queryable archive.
What it can do
It indexes 50+ file types, answers complex questions with citations, opens results at precise locations, auto-organizes folders, renames files by content, extracts structured data to CSV, and runs completely offline.
Who is it for
Mac power users, lawyers, researchers, finance and operations professionals, creatives, and anyone who needs to find answers inside a large, messy local file library while keeping data private.
