About Fenn

What Is Fenn

Fenn is a Mac app that turns everything stored on your computer into something you can search in plain language. You type what you remember, not the exact filename, and it pulls up the right page, timestamp, or screen. The search covers 50+ file types, including PDFs, Word documents, spreadsheets, Adobe project files, audio, video, and your notes from apps like Notion and Apple Notes.

The pitch is privacy. Indexing runs on your Mac, and files never leave the machine. That matters if you handle client work, legal documents, or anything you would not hand to a cloud service. Fenn is built for Apple Silicon Macs, so it will not run on older Intel models.

Getting Started

  1. Download Fenn from the official site. It runs on Apple Silicon Macs only.
  2. Grant access to the folders and drives you want indexed, then let it build the local index in the background.
  3. Search by meaning. Type a description of the file, the content, or a moment you remember, and Fenn returns matches across documents, audio, and video.
  4. Set up extras if you need them. Auto-organize folders, AI renaming, the file anonymizer, and CSV extraction all work from the same index.
  5. Chat with your files and get answers that cite the source page or timestamp.

Key features

Private on-device indexing

Every file is indexed on your Mac, and nothing gets uploaded. Fenn works offline too, so a spotty connection never blocks a search. The trade-off is that the index lives on your disk and takes up space, but you control which folders it covers.

Search inside 50+ file types

Fenn works as an AI document search tool that reads documents, spreadsheets, presentations, Adobe project files, developer files, images, audio, and video. That range is the point. Most desktop search stops at text documents, so video and layered design files stay invisible until you open them.

Screen memory search

Fenn captures what you saw on screen and makes it searchable, which covers meetings, shared dashboards, and chats that never got saved as a file. It brings back the page or moment itself, not just a link to it.

Semantic and agentic search

As an AI file search app for Mac, Fenn lets you describe what you want in normal words and Fenn matches by meaning, not just keywords. Agentic search goes a step further and chains lookups across many files to answer a broader question.

Chat with your files

Ask questions, summarize a document, compare two versions, or pull out a specific detail. Answers come with citations back to the source page or timestamp, so you can check the result instead of trusting it blindly.

AI renaming and auto-organize

Fenn renames files based on their content and builds folders that stay up to date with rules you set. For anyone with years of inconsistently named exports, this removes a lot of manual cleanup.

Pros and cons

Pros

  • Files never leave your Mac, so confidential work stays private and offline search keeps working.
  • Searches inside video, audio, images, and Adobe design files that most tools skip.
  • Screen memory search finds things you saw but never saved as a file.
  • Chat answers cite the source page or timestamp, so results are verifiable.
  • One-time lifetime license available if you would rather not pay monthly.

Cons

  • Apple Silicon only, so Intel Mac users cannot run it at all.
  • No free plan, which makes it hard to test before paying.
  • The local index uses disk space, a real cost on smaller drives.
  • Core features need broad file and screen access, which some users will not want to grant.

Frequently asked questions

No. Indexing and search run on your Mac, and Fenn says files never leave the device. It also works offline, so nothing depends on a server staying up. You can use it as a local file search engine even in airplane mode.
