Turn every conversation into knowledge

Each message is a building block of your knowledge base. Each branch is an extension of your thinking — built for deep thinkers.

Conversation Knowledge Base

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.

Branching Thinking

Git-style branch management — fork, merge and rewind your thinking freely. Explore every line of thought without ever losing your way.

Multi-Model Parallel Chat

Ask GPT, Claude, Gemini and more simultaneously. Compare answers side-by-side to surface the sharpest insight.

AI App Full Lifecycle Management

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.

Unified AI-Powered Search

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.

Multi-Tab Management

Open multiple chats simultaneously with IDE-style tab switching, perfect for managing parallel tasks.

Prompt Templates

Create and manage reusable prompt templates with enable/disable toggle. Insert any prompt into conversations with one click.

Professional File Library

Complete file management system with upload, preview, organization, and search for all your documents and media files.

Cloud Sync Across Devices

Seamless synchronization of your settings, apps, and preferences across all your devices, keeping everything in sync wherever you go.

Every detail, built for knowledge

Crafted for deep thinkers — where knowledge management meets AI conversation

AI Auto-Naming

AI generates chat titles from context — say goodbye to 'New Chat 1, 2, 3...'.

Input History

Auto-saved message history for one-click reuse across sessions.

Message Quick Actions

Right-click menus for copy text/image, delete, fork branch, and exclude from context — precise control over every message.

AI Image Semantic Search

Every AI-generated image is indexed with vector embeddings, enabling semantic search so you can instantly find any image from your conversation history.

Multimodal I/O

Chat with images, audio, and video. AI understands and responds across media types.

Structured Folder Management

Nested folder hierarchy for chats, apps, prompts and knowledge with pin, sort and folder-level parameter inheritance.

File Attachment Support

Drag, paste or click to upload images and documents, stored per message.

Fine-Grained Parameters

Tune temperature, sampling, context window and reasoning effort independently per branch — full control over every generation.

Background Streaming Resumption

AI generation continues in the background and automatically resumes when you return, even after page refresh or network interruption.

End-to-End Encrypted Storage

All your conversations are encrypted before being stored in our database. Your private data is never sold or shared with any third party.

Transparent Credit Billing

Credits consumed per reply shown in real-time, usage at a glance.

Invite Friends, Both Win
