## Interview Coder

Interview Coder is a native desktop app rather than a web service. You install it on Windows or macOS, join your scheduled interview as usual, and the application captures the interviewer's audio, transcribes the question and generates a response — typically runnable code for algorithmic prompts or structured talking points for behavioural rounds. The tool covers the common formats, including LeetCode-style coding, system design, full-stack, data analyst, AI/ML, consulting, trading and product roles.

The distinguishing feature is its stealth layer. The vendor advertises more than twenty undetectability measures: no icon in the dock or tray, a disguised process name that stays hidden in the activity monitor, an overlay that does not appear when the screen is shared, click-through behaviour so hovering does not register, and operation outside the browser so extension-based detection never sees it. Compatibility pages track platforms such as Microsoft Teams, Zoom, Google Meet, Amazon Chime and Cisco Webex and state whether the app is currently undetectable on each.

The company says the tool is used by 150,000+ candidates and publishes offer screenshots and testimonials from users who landed roles at large technology firms. That framing makes the product inherently controversial: using an undisclosed assistant during a live evaluation generally breaches interview terms of service and can lead to offer withdrawal or a ban, so it is materially different from ordinary practice tools. Pricing combines a free downloadable app with paid AI features — the site lists a monthly Pro subscription and a one-time lifetime Pro option, both unlocking audio support, undetectability features and the tuned models.

**Pricing & Plans:** Free download with the assistant app and undetectability features; AI usage requires a paid plan. The vendor lists a monthly Pro subscription (advertised at roughly $299/month) and a one-time Lifetime Pro option (roughly $799), both including a monthly allowance of usage credits.

- **Real-time coding assistance:** The assistant transcribes the question as it is asked and returns a working solution you can read from the overlay, aimed at LeetCode-style prompts.
- **Live audio transcription:** Captures and transcribes the interviewer's speech so the AI can follow questions delivered verbally during the call.
- **Stealth overlay:** The window stays out of screen shares, dock, taskbar and the activity monitor, with click-through behaviour and a disguised process name.
- **Coverage across interview formats:** Targets coding, system design, behavioural, full-stack, data, AI/ML, consulting, trading and product interviews rather than only algorithms.
- **Cross-platform compatibility tracking:** Lists interview platforms such as Teams, Zoom, Meet, Chime and Webex with a current undetectability status you can check before a call.

**Strengths:** Purpose-built stealth features that go beyond a normal AI chat window; Supports audio input so it can follow spoken questions during a live call; Works across coding, system design and non-technical interview formats; Publishes a compatibility list that is reported as retested against major interview platforms

**Limitations:** Using a hidden assistant in a proctored interview usually violates the employer's terms and can cost you an offer; The Pro pricing is high relative to typical interview prep budgets; Effectiveness depends on the platform and on staying undetected, so it is fragile by design

## 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
