BrainTab

AI-powered second brain that automatically remembers, summarizes, and connects everything you learn while browsing.

BrainTab — Your AI-Powered Research Assistant Never lose anything you learn online. BrainTab is your AI-powered research assistant — it remembers, summarizes, and connects everything you read, so you can find it again in seconds. The Problem Information overload is real. You keep 50 tabs open because closing them feels like losing something. You bookmark articles you never revisit. Three weeks later, that one page you needed is buried somewhere in your browser history — or gone. The Solution BrainTab works quietly in the background as you browse. It reads, summarizes, and extracts the key ideas from every page you visit — building a personal, searchable knowledge base without any extra effort from you. Core Features 🤖 Meet Kira: Your AI Research Copilot Stop switching tabs to use a separate chatbot. Kira lives in your side panel and already knows what page you're on. Ask her to explain something, summarize an article, or pull up something you read last week. 🌌 Interactive Knowledge Graph See how everything you've researched connects. BrainTab maps relationships between topics and pages into a visual, explorable graph — so you can rediscover ideas you'd otherwise forget. ⚡ Automatic Summaries & Tagging No manual tagging, no folders to organize. BrainTab automatically summarizes pages and extracts key entities — tools, people, concepts — as you browse. 🛡️ Private by Design Your data stays local by default. Export your entire knowledge base to JSON or PDF anytime. Browsing privately? Toggle Incognito Mode and BrainTab pauses capture instantly. How It Works Step 1 — Install Add BrainTab to Chrome.
