Why Anvil?

Multi-Provider

Switch between Anthropic Claude, OpenAI OpenAI, local Ollama, and xAI Grok instantly with /provider. Smart failover auto-switches when rate limits hit.

1M Token Context

Never lose context. When the window fills, conversations are automatically archived and indexed. QMD-powered retrieval brings relevant history back on the fly.

44+ Built-in Tools

Bash, file operations, 8 web search providers, MCP servers, LSP integration, image generation, and more. Extend with skills and plugins from AnvilHub.

Full-Screen TUI

Tabbed sessions, streaming output, tool call visualization, and a rich status footer. Vim keybindings, file drag-and-drop, and image paste support.

Persistent Memory

QMD knowledge base automatically injects relevant context from your codebase and previous sessions. Pin files, search inline with /qmd.

Interactive Configuration

Full interactive /configure menu with arrow-key navigation. Manage providers, models, context, search, permissions, and integrations without leaving the TUI.
