Switch between Claude Sonnet 4.5, Opus 4.5, and Haiku 4.5 mid-conversation with full token streaming.
Drag PDFs, DOCX, CSV, JSON, and images straight into the composer. Claude reads them inline.
Tabbed browsing with a "Send page to chat" pill, plus Anthropic web search routed through your turn.
Pre-prompted entry points for Code Generator, SQL Builder, Regex Builder, System Designer, and more.
Group chats under projects with shared context, or invent custom personas with their own system prompts.
HTML, SVG, and Mermaid output rendered in a side panel as Claude streams it. Inspect the code or download it.
