Lectio vs Sheaf

Lectio is an OCR tool that lets you choose the engine for each task. It combines on-device recognition, professional OCR services and leading large language models to extract text from images, organize documents and convert formats. Photos, scans, PDFs, handwriting, classical texts, tables, complex formulas, columns and mixed layouts can all become editable, exportable content. Lectio preserves the original hierarchy, paragraphs and layout wherever possible, reducing manual entry and reformatting. Switch between recognition engines based on the file and use case, choosing the right balance of speed, accuracy and layout preservation. —USE CASES— ● Organize lecture slides, books and study materials Extract text, tables and formulas from slides, textbooks, notes and exercises with less manual typing. ● Recognize handwriting and classical texts Extract handwritten notes, annotations, classical works and historical documents for easier organization, search and storage. ● Prepare image content before asking AI When AI cannot read an image clearly, first convert it into structured text, then copy it into your conversation. ● Extract contracts, reports and paper documents Turn contracts, reports, scans and other paper materials into content that is easier to edit, archive and search. ● Recognize complex formulas and specialist material Process mathematical formulas, technical documents, research material and complex symbols while preserving structure wherever possible. ● Capture foreign-language text from video Extract foreign-language text from screenshots, subtitle frames and film clips for translation, study and organization. ● Convert complex documents Process files with tables, formulas, columns, hierarchies and mixed layouts, then convert them for editing or archiving. —CORE FEATURES— 1.
