Everything a long-running AI conversation needs.

Prompt library and personas

Titled prompts with fill-in-the-blanks and version history, free.

Chat with documents

Answers grounded in attached files, with the sources shown under the reply.

Memory that lasts

Per-chat memory that shows exactly which memories each reply used.

Search everything

Find a phrase in one chat or across all of them.

Pro

Let capable models take action.

Pro adds larger local and cloud models, tools and goal-driven Agent mode — with every tool call and agent step shown in full.

Tools

Calculator, clock, web search, open web page and your own MCP tool servers.

Agent mode

A planner splits a goal across parallel agents, then merges and recommends.

AI Assistant, AI Chatbot or AI Reasoning?

Privacy boundary

Choose a local model and keep the work on your device.

Prompts, documents and results stay local on the local-model path. If this app supports an optional cloud provider, the app identifies that route before use.

Questions

AI Chatbot questions, answered.

Does AI Chatbot work offline? +

Yes, with the built-in local model. It downloads once on first launch, then works without a network connection and without an account.

What is free and what is Pro? +

Folders, branching, the prompt library, document chat and memory are free on the local model. Pro adds larger models, cloud providers, tools and Agent mode.

Do my chats leave my PC? +

Not with a local model: inference runs on the machine and history is stored encrypted. A cloud model you choose sends messages to that provider.

How is it different from AI Assistant and AI Reasoning? +

AI Assistant is fast, focused chat; AI Reasoning is tuned for multi-step problems; AI Chatbot is the full workspace with documents, memory, tools and agents.
