When to choose Acrobat

Choose Adobe Acrobat when your day is spent making and changing PDFs: editing text, filling and building forms, collecting e-signatures, converting files to and from Office formats.

Choose Eno when you mostly read PDFs and need to understand what's in them. It's free for reading and search, and when a document gets long or complicated you can ask a question and see the exact passage that answers it.

Why people look for an alternative to Adobe Acrobat

The price creeps up

Adobe's paid plans start at $9.99 a month, and the price climbs as you add features. That's a lot to pay for opening files. Eno is free for reading and searching PDFs, and you only buy credits if you want AI answers.

Free, with an asterisk

Acrobat Reader is free, but plenty of its buttons lead to a paywall. Want to chat with a document or summarize it? That's a paid plan. Eno gives you 1,000 free AI credits to try it, then lets you pay per search. No subscription to forget about.

Too much app for the job

Most people open Acrobat to read a PDF and find one thing in it. Eno is built around that: open a document, or a whole folder of them, and find what you need.

Your files, somewhere else

Eno runs on your computer and reads files straight off your hard drive. Zero cloud storage, zero data retention, and SOC 2 certified.

What you get with Eno, free

Read and search PDFs for free

Viewing and text search never cost credits. Not after a trial, not ever.

Scanned PDFs work too

Built-in OCR turns scanned pages into text you can search.

Word documents open as well

Keep your .docx files in the same place as your PDFs.

Big files are fine

Search thousand-page PDFs and whole folders. A workspace holds up to 2GB, about 60,000 pages.

Ask when you're stuck

Type a question and Eno gives a short answer with the exact passage highlighted in your original document. Verify the AI's claims in one click.

Runs on your machine

Native app for Mac and Windows. Your files stay on your hard drive, or connect Google Drive or Box.

“Ask eno a question and it shows you the answer. It does not tell you. It saves you the time of searching, but leaves you to review and analyze the data yourself.”
