A minimal, extensible terminal coding agent you can reshape
Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git.
AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control.
Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session.
Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent.

The documentation platform that keeps docs accurate for people and AI
Write with a block-based visual editor, reusable content blocks, and custom components that keep large docs consistent.
Sync a GitHub or GitLab repo and branch, review, and merge documentation changes like pull requests.
Readers can ask your docs questions directly and get contextual answers pulled from your content.
GitBook scans for content that no longer matches your product and flags it for review before wrong answers spread.
