## Pi Coding Agent

Pi is a terminal-based coding agent built around one idea: the harness should adapt to your workflow, not the other way around. It keeps a deliberately small system prompt and core, which makes it token-efficient and lets you control exactly what lands in the context window. Instructions come from AGENTS.md files, a per-project SYSTEM.md, on-demand skills, reusable prompt templates and extensions that can inject context before each turn.

Instead of shipping every feature, Pi exposes primitives. Sub-agents, plan mode, permission gates, path protection, sandboxing, SSH execution, custom editors and status bars can all be built with extensions, asked for in natural language, or installed from third-party packages on npm and git. MCP is built in, and Codemode lets agents compose tool calls inside a JavaScript sandbox. Session history is stored as a tree, so you can rewind to any earlier message, branch from there, and export or share the whole thing.

Pi runs in four modes: the full interactive TUI, print/JSON mode for scripts and pipelines, an RPC protocol over stdin/stdout for non-Node integrations, and an SDK for embedding it in your own apps. It connects to 15+ providers including Anthropic, OpenAI, Google, Azure, Bedrock, Mistral, Groq, Cerebras, xAI, Hugging Face, OpenRouter and local Ollama, and you can switch models mid-session with a keystroke. Models, packages, changelog and docs all live on the project site.

**Pricing & Plans:** Free and open source (MIT). You only pay your chosen model or API provider; no subscription is required for the agent itself.

- **Extensible harness:** Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git.
- **Context engineering:** AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control.
- **Multi-provider models:** Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session.
- **Four run modes:** Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent.
- **Tree-structured history:** Rewind to any previous message, branch from it, and export to HTML or share the session via a gist URL.

**Strengths:** Open source under MIT with a minimal, readable core; Highly extensible: add or install the features other agents hard-code; Token-efficient thanks to a small system prompt; Broad model support with mid-session switching and local Ollama options

**Limitations:** Deliberately ships without sub-agents, plan mode or permission popups by default; You may need to build or install extensions to get a full-featured experience; Terminal-centric UI has a learning curve if you expect a GUI

## GitBook

GitBook has evolved from a simple Git-based writing tool into a full documentation platform built around accuracy. Teams design and publish docs in a block-based editor, keep them in sync with source control, and use AI to make sure readers and agents always get the right answer. Its headline promise is that the docs platform should flag outdated content and then help fix it, rather than only making content machine-readable.

The workflow combines familiar docs-as-code habits with modern AI. You can connect a GitHub or GitLab repository and treat documentation like software, branching, reviewing, and merging changes. On top of that, GitBook Agent can write, edit, and update pages, while AI Insights tracks where readers and agents get stuck so you know what to improve next. AI Assistant turns your docs into an interactive support surface that answers questions in context.

For AI consumption, every published GitBook site automatically generates an MCP server and ships with LLM optimizations, so coding assistants and other agents can read and trust your documentation. With SOC 2, ISO 27001, and GDPR compliance, SAML SSO, and authenticated access options, GitBook targets both startups and enterprise documentation teams that need security and control alongside speed.

**Pricing & Plans:** GitBook is freemium. A Free plan covers individuals. Essential starts at $65 per site/month and Ultimate at $249 per site/month (billed annually), with additional team members at $12 per user/month. Monthly billing runs $79 and $299 per site/month with users at $15. Enterprise pricing is custom, and AI credits can be purchased in bundles.

- **Block-based editor:** Write with a block-based visual editor, reusable content blocks, and custom components that keep large docs consistent.
- **Git Sync and docs-as-code:** Sync a GitHub or GitLab repo and branch, review, and merge documentation changes like pull requests.
- **AI Assistant:** Readers can ask your docs questions directly and get contextual answers pulled from your content.
- **Stale content detection:** GitBook scans for content that no longer matches your product and flags it for review before wrong answers spread.
- **AI insights and analytics:** See where users and agents get stuck, which answers were given, and which pages to fix first.
- **AI-ready publishing:** Every published site becomes an MCP server, connects via WebMCP, and includes LLM optimizations for AI agents.

**Strengths:** Free plan and 14-day trials make it easy to evaluate; Docs-as-code workflow with real Git branching and review; AI features directly target stale and inaccurate content; Strong enterprise security and compliance credentials

**Limitations:** Per-site plus per-user pricing can add up for larger teams; Some advanced AI features are gated to the Ultimate tier; Building a custom theme still assumes some technical comfort
