Search Inside a PDF on Mac, Down to the Exact Page (No Cloud Needed)

If you’ve ever tried to find a specific moment buried deep inside a long PDF, you know the struggle. Spotlight can’t do it. Preview is hit or miss. And cloud services? Not everyone wants to upload their private documents to a server just to find a line of text.

Fenn fixes this. With on-device intelligence, it lets you search inside any PDF on your Mac—without keywords, without cloud indexing, and without friction.

Let’s break down how it works and why it’s a big deal for anyone dealing with long documents, reports, or cluttered file folders.

The Problem With Mac’s Built-In PDF Search

Spotlight doesn’t really “read” your documents. It skims the surface.

You can try typing in a filename or even a phrase you think is inside a file. But unless that file was indexed just right, or the phrase appears in metadata, you’re left empty-handed. And if the PDF is scanned, good luck.

Same story with Finder and Preview. You might find the file, but scrolling through dozens of pages to find the exact section you need is a waste of time.

Fenn Finds the Exact Page You Need

Fenn uses local AI to index the actual content of your PDFs. Not just the file name or tags, but what’s inside.

You can type what you remember, even if it’s vague:

“Page with the French flag”
“Mental health checklist for founders”
“Slide about Q3 revenue breakdown”

Fenn doesn’t need the exact words. It understands your intent. Then it pulls up the relevant document and jumps to the exact page that matches your description.

No Uploads, No Privacy Concerns

Everything happens locally on your Mac.

There’s no sending your PDFs to a server, no cloud syncing, and no waiting for re-indexing. Fenn uses Apple Silicon and MLX to process everything on-device, instantly and securely.

If privacy matters to you, this is the only way to search without compromise.

When Would You Actually Use This?

This isn’t just for research nerds or academics. It’s useful in real life:

Founders skimming pitch decks or old PDFs from investors
Designers looking for visual references inside inspiration files
Lawyers searching case law snippets buried in long documents
Students trying to find quotes inside scanned study material

Bonus: Search Without Keywords

The biggest unlock is that Fenn doesn't need you to remember the right word. Just describe the idea.

“Checklist for launching”
“Quote about burnout”
“Chart with sharp upward trend”

You get results based on meaning, not matching characters.
