About

Brainfo is an AI-powered productivity platform designed to help users build a digital “second brain” for organizing ideas, knowledge, and tasks. The platform combines note-taking, document creation, task management, and goal tracking into a single integrated workspace. Inspired by Tiago Forte’s CODE methodology, Brainfo helps users capture, organize, distill, and express information effectively. Users can store notes, bookmarks, documents, and databases in one system to manage both personal and professional knowledge. The built-in AI assistant supports tasks such as writing improvement, summarization, translation, brainstorming, and content generation. Brainfo also allows users to access multiple AI models, including ChatGPT, Claude, and Gemini, within one interface. By unifying productivity tools and AI capabilities, Brainfo helps individuals and teams think more clearly and work more efficiently.

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.
