Found free AI software-Perplexity AI and Semafind-AI

Semafind is an AI-powered knowledge management tool designed to help users organize and discover their private knowledge in a meaningful way. Users can create knowledge repositories by storing short factual sentences called "knotes". Knotes can be expanded with further descriptions and attachments such as documents, images, and videos. Semafind supports comprehensive Markdown, allowing users to easily format and style text. The tool utilizes state-of-the-art natural language understanding technology, enabling users to interact with their knowledge naturally through questioning rather than traditional keyword searches. Semafind indexes the knowledge repository using natural language models and finds answers based on their meaning. Semafind also offers semantic exploration, allowing users to discover and navigate unknown and related clusters of knowledge based on semantic similarity. The tool visualizes relevant information as nodes in a graph, making exploration and gaining insights from hidden connections in the knowledge repository easy. Users can share their knowledge repositories with colleagues, invite collaborators to collaborate on their knowledge repositories, and restore knowledge history for up to 30 days. Semafind offers a free personal knowledge management account option and two paid subscription plans for companies and teams.
