Quivr

Quivr is positioned as an individual’s “second brain” — not just a knowledge base for answering questions, but also an AI-powered knowledge management system. It allows users to upload various types of content such as text, images, audio, and videos to build their knowledge bases. The AI then uses this information to provide answers, generate summaries, and establish connections between different pieces of data. With an interface style similar to Obsidian, it supports both public and private sharing. It is suitable for personal knowledge management, academic research, and managing creative assets.
