Eno PDF Reader
AI that shows its work — every answer traced back to your documents
Overview
Eno is an AI document reader for Mac built around verification rather than blind trust. Ask a question across your PDFs and Word files and Eno surfaces the exact passages the answer rests on, so you can read the source language yourself instead of taking a paraphrase on faith. It reads across large collections and thousand-page files, indexing documents straight off your hard drive — nothing is stored in the cloud, and only short text snippets are sent through Eno's servers to Google's models under zero-retention terms. Built by veterans of the legaltech industry, it is aimed at lawyers, engineers, academics, and real estate professionals whose credibility depends on getting the citation right. Basic viewing and text search are always free, AI searches run on pay-as-you-go credits, and you can connect a local LLM to skip credits entirely.
Pricing: Free viewing + 1,000 welcome credits | Credits $15 per 5,000 (~50 searches) | Free with your own local LLM
Minimum macOS: 14.0 (Sonoma)
