About

Lectio

Features
Read full description

A photo saves the page. Lectio helps you keep working with what's on it. Bring handouts, paper documents and images into a library where you can read, compare and reuse the content. Start with the page in front of you. Capture a handout, note or document, or import existing images and supported files. Choose a recognition engine for the material and extract its text. For tables, formulas and complex layouts, keep the original image close at hand to check the result. Read a page at a time. Move through the document and return to its original image when you need to verify a detail. Generate a translation for foreign-language material and read it alongside the source, keeping your understanding connected to the original. Build something from the collection. Group material for a course, a trip or a work topic into projects. Return to your library, check processing progress and export useful results for notes, reports or the next piece of work. Choose the right tool for each document. Use the in-app cloud engine or configure a supported provider's API key. Recognition and layout results depend on image quality, language and the selected engine. Cloud processing sends the required content to the relevant service. Purchases and usage Lifetime is a separate one-time unlock. Boundless Go, Plus and Pro are monthly or yearly auto-renewing plans with shared app benefits and cloud usage.
