About

Joindex’s product Dex turns your browser into a single AI-powered workspace and “second brain” that understands your tasks, context, and workflows across all your tabs and connected apps so you can handle work faster without switching between tools. It connects with popular apps and services, remembers preferences and context, and surfaces relevant suggestions, notes, links, and actions right when you need them, helping with tasks like scheduling meetings, summarizing content, scraping and exporting data, managing emails, and automating repetitive steps directly in your browser. Dex organizes AI-generated notes and todos into retrievable memory, predicts what’s next based on your activity, and works across multiple applications and tabs so you don’t lose context or waste time digging for information, while privacy controls let you manage permissions and data access.

About

HeyBrain is an AI-powered knowledge management platform that helps organizations centralize company information and make it accessible to employees and AI agents. The platform provides a shared knowledge layer for organizing documents, project context, business decisions, and reusable instructions. Its AI memory capabilities allow compatible AI assistants to retrieve relevant information across conversations and workflows without repeatedly providing the same background. HeyBrain supports document uploads, knowledge connections with Google Drive and Notion, and integration with AI tools through the Model Context Protocol (MCP). Its governance capabilities help organizations manage access to shared information, define agent permissions, and review source evidence behind AI-generated answers. The platform is designed to support enterprise knowledge retrieval, AI agent development, team collaboration, and secure information sharing across business applications.
