Our verdict on Eno PDF Reader

Eno PDF Reader is a desktop app for people who need to research collections of PDFs and Word documents, including legal, engineering, finance and real-estate work. It runs on Windows and macOS, indexes local folders, and supports PDF, Word, Markdown and Outlook MSG files. Ask Eno answers questions with visual citations to source passages, while OCR helps make scanned PDFs searchable. Its multi-pane workspace is suited to readers who move between documents and source material; it is less relevant for people who mainly want a browser-based or mobile reading app.

For document-heavy work, the feature set reaches beyond question answering: Eno searches across folders and multiple documents, extracts PDF tables for pasting into Excel, and can chart table data. Integrations with Google Drive, Box and Clio extend search to those services. Documents remain on the user’s computer, while snippets are sent for AI processing. That distinction matters for teams evaluating document handling. The product lists SOC 2 compliance and email support, but its use case is especially compelling when cited answers, scanned-file OCR and table work are central requirements.

The Free plan includes document opening, reading, organization and search, plus 1,000 welcome credits for Ask Eno. Pay as you go costs $15 for 5,000 credits; it adds questions with visual citations, answers grounded in text, scanned and table data, and search across Google Drive, Box and Clio. Credits are usage-based: welcome credits expire after 90 days and purchased credits after one year. Enterprise offers a negotiated MSA, usage pooling and the option to bring an API key from major LLM providers. Choose Eno for desktop research across complex PDF collections; look elsewhere if you need a monthly subscription or a non-desktop app.
