## GhostCoder

GhostCoder is a desktop application built for one specific job: giving you AI coding help during live technical interviews without interviewers noticing. Rather than a browser extension, it is a native Mac and Windows app so it can integrate deeply with the system, support global hotkeys, and let you interact without a single key press or mouse click.

The workflow is explicitly stealth-oriented. The app reads what is currently on your screen, sends that context to an AI model using your own API key, and returns code suggestions, explanations, or solutions in an an invisible overlay — one that only you can see through your own screen, so it stays out of any screen-share window. It advertises support for OpenAI, Google Gemini, and Anthropic Claude, with more platforms planned.

The commercial model is unusual for this category because it is a one-time purchase rather than a monthly subscription. You buy the license once (advertised at $40, reduced from $100) for unlimited use on a single device, with a year of free updates, and you pay only for your own AI usage through your API keys. A free trial version is available so you can test compatibility with your screen-sharing software before buying, and the company notes it does not offer refunds. The app requires no account, which the developer frames as a privacy benefit.

**Pricing & Plans:** Free trial plus a one-time purchase. The full license is advertised at $40 per license (discounted from $100) for unlimited use on a single device with one year of free updates, plus your own AI API usage costs. No subscription; the site states refunds are not offered.

- **Invisible on-screen overlay:** AI suggestions appear in a modal only you can see, keeping them out of screen-sharing captures.
- **No clicks or key presses:** Hover-to-click interaction removes visual and audio cues that could give you away during an interview.
- **Bring your own AI key:** Query OpenAI, Google Gemini, or Anthropic Claude directly with your key, paying only for what you use.
- **Screen-context awareness:** The app reads what is on screen and uses that context to produce relevant code, explanations, or solutions.
- **One-time purchase, no account:** Buy once for unlimited single-device use with no subscription, and no account is required for privacy.

**Strengths:** One-time purchase model rather than a recurring subscription; Uses your own API keys, so usage costs stay in your control; Desktop app with global hotkeys and click-free interaction for discretion; Free trial lets you verify it works with your screen-sharing setup first

**Limitations:** The developer cannot guarantee it stays undetectable in every situation; No refunds are offered once purchased; Designed for interview assistance, which raises ethical and employer-policy concerns

## 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
