Every chat builds your knowledge
Every conversation you have becomes lasting knowledge. Branch your thinking to explore ideas freely. Compare GPT, Claude, Gemini and more — with AI memory that grows smarter over time.
Each message is a building block of your knowledge base. Each branch is an extension of your thinking — built for deep thinkers.
AI automatically extracts key knowledge from your chats, builds vector indexes, and injects the most relevant context every time — your knowledge base gets smarter with every conversation.
Git-style branch management — fork, merge and rewind your thinking freely. Explore every line of thought without ever losing your way.
Ask GPT, Claude, Gemini and more simultaneously. Compare answers side-by-side to surface the sharpest insight.
From creation to iteration: describe your idea in plain language to generate an HTML app, then discuss and refine it with AI-powered collaboration and real-time previews.
One powerful search interface for everything: Ctrl/Cmd+K global search, AI-powered semantic search across all chats and knowledge, plus category filtering, recent access, and search history.
Open multiple chats simultaneously with IDE-style tab switching, perfect for managing parallel tasks.
Create and manage reusable prompt templates with enable/disable toggle. Insert any prompt into conversations with one click.
Complete file management system with upload, preview, organization, and search for all your documents and media files.
