Side by side
Anthropic's AI assistant for writing, analysis, coding and long documents, with projects, connectors to other apps, and Team and Enterprise plans.
A lightweight AI chat client for web and desktop that works with your own API keys for OpenAI, Claude, Gemini, DeepSeek and others, or through its paid account service.
Usage limits apply even on paid plans, and like any model it can state wrong things with confidence.
The project now steers users toward its own paid service, and team features are limited.
