## 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

## soai Extensions

soai Extensions, short for Self Operating AI, is a browser extension built around a simple idea: you should be able to describe a task in everyday language and have the computer carry it out, rather than memorising menus, keyboard shortcuts and click paths. The extension listens to natural-language prompts and translates them into actions, positioning itself as a hands-free layer over your normal desktop and browser workflow.

The appeal is mainly convenience and accessibility. Hands-free operation can help users who have difficulty with precise mouse and keyboard input, and it can speed up repetitive tasks for anyone who would rather speak an instruction than navigate a long sequence of steps. Because it runs as a Chrome extension, installation and removal are quick and it works alongside whatever else you already have in the browser.

The extension is published by the SOAI Team and is listed on the Chrome Web Store as version 1.0, with a free listing and no developer-reported data collection. It is a small, early-stage project with a limited user base, so it is best suited to people who want to experiment with voice-controlled computing rather than those needing an enterprise-grade automation suite.

**Pricing & Plans:** The extension is listed for free on the Chrome Web Store with no paid tiers described.

- **Natural-language control:** Issue instructions in everyday language and let the extension interpret and carry them out.
- **Voice-driven operation:** Operate your computer hands-free instead of relying on mouse and keyboard sequences.
- **Task automation:** Reduce repetitive clicking through menus and multi-step workflows.
- **Accessibility support:** Offers an alternative input path for users who find precise pointer and keyboard control difficult.
- **Chrome extension install:** Installs and uninstalls directly from the Chrome Web Store alongside your existing browser setup.

**Strengths:** Free to install from the Chrome Web Store; Natural-language prompts replace memorising menus and shortcuts; Hands-free use can help users with motor or dexterity limitations; Lightweight extension that sits alongside your existing browser workflow

**Limitations:** Small project with a very limited user base and no ratings yet; Last listed update was version 1.0 in April 2024, so development appears slow or stalled; Natural-language computer control can be inconsistent for complex or multi-app tasks
