Instead of adopting a docs framework, you keep writing plain Markdown, and Notation publishes it into a Notion workspace where your whole team — engineers and non-engineers alike — can read, search and comment on it. Setup is deliberately minimal. You install the binary with a one-line curl script, create a Notion internal integration to get a secret, put that secret and a parent page name into ~/.notation/Notation.toml, connect the Notion page to the integration, and then run notation ship --src . Notation walks the folder, creates a page for each file, mirrors nested directories as subpages, and converts relative links between Markdown files into working Notion page links. The tool also supports a few quality-of-life extras. An intro.md file in a directory renders on the parent page instead of creating a child page, and per-file --title and --emoji arguments let you control how each page appears in Notion. Deployment is flexible: keep it internal, share the Notion page publicly, or front it with a website builder such as Super. Notation is free and its own documentation site is itself managed by Notation, which is a neat demonstration of the workflow. **Pricing & Plans:** Free and open source. The CLI is distributed through GitHub, so there is no subscription or per-seat fee — the only requirement is a Notion account plus an internal integration for API access. - **One-command Markdown publishing:** Run a single command to push a folder of Markdown files into a Notion parent page, creating subpages from your directory structure. - **Simple TOML configuration:** Store your Notion integration secret and parent page name in ~/.notation/Notation.toml with no other setup. - **intro.md for parent-page content:** Rather than creating a subpage, an intro.md file renders its content directly on the parent Notion page. - **Per-file title and emoji arguments:** Set the Notion page title and icon per file using --title and --emoji flags at the top of your Markdown. - **Notion AI, search and formatting inherited:** Because everything lands in Notion, you inherit Notion AI, full-text search, tables of contents and rich formatting without building any of it. **Strengths:** Docs stay in the repo and go through the same review and CI flow as code; Zero frontend framework to maintain — plain Markdown only; Inherits Notion AI, search, formatting and commenting for free; Non-engineers can read docs in a familiar Notion interface [Profile (Markdown)](https://openaitools.app/tool/notation.md) ## 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 [Profile (Markdown)](https://openaitools.app/tool/pi-coding-agent.md) ## Frequently Asked Questions ### How do Notation and Pi Coding Agent compare in monthly traffic?
