## Description

**KnowledgeBase Builder Lite** is a personal knowledge management and “second brain” app for building expansive, interconnected knowledge networks. Create 3D mind maps, concept maps, flowcharts, org charts, family trees and mathematical diagrams with labeled relationships, automatic layouts, tags, categories and live filters.

Use the infinite whiteboard, rich-text notes, checklists, attachments and kanban or scrum boards to organize ideas, projects and research. Search across node titles and attached documents, import content from Wikipedia, Wikidata and Obsidian, generate flashcards with spaced repetition, and use AI features through Model Context Protocol support. The Lite edition includes all features without ads, subscriptions or time limits, with one knowledge base capable of holding millions of items. Data is stored locally in a SQLite-based `.kdb` file, with flexible import and export options.
