## Interview Solver

Interview Solver targets the practical mechanics of live technical interviews. The desktop application can screengrab any window and send the captured problem to an AI model that returns a working solution, along with an explanation of the approach and complexity notes. Voice transcription captures both your microphone and the interviewer's audio, so spoken questions in system design or behavioral rounds also produce answers.

A strong emphasis is placed on staying invisible during the interview. The app is designed to be hidden from Zoom screen sharing and browser-based recording, uses global hotkeys that don't require alt-tabbing, and is reported as invisible in the macOS Activity Monitor. A Companion mode pairs the desktop app with a phone, letting you trigger screenshots, voice capture and prompts remotely, which is useful when an assessment tool logs keystrokes on the interview laptop.

Setup starts with a free trial that needs no credit card, covering 10 minutes and 10 AI answers. Beyond that, subscriptions are simple: a monthly plan for a single interview loop or a three-month plan covering a full job search cycle. The product also ships free side utilities such as an ATS resume checker, a STAR method builder and a salary lookup.

**Pricing & Plans:** Free trial with no credit card: 10 minutes and 10 answers, everything included. Paid plans are $59 per month for one interview loop, or $149 every three months (about $50/month) for a full interview cycle.

- **Invisible during screen sharing:** The desktop app is designed to remain hidden from Zoom and browser-based screen recording, with moveable overlays and no visible taskbar presence.
- **Screengrab solving:** Capture any window containing a coding problem and receive a complete solution with syntax highlighting, approach notes and complexity analysis.
- **Live voice transcription:** Transcribes both your voice and the interviewer's audio so spoken system design and behavioral questions can be answered in the moment.
- **Companion mode and mobile:** Pair the desktop app with a phone for remote screenshots, prompts and answers, or use the browser-based mobile mode with no installation.
- **Undetectable global hotkeys:** Trigger answers without alt-tabbing or moving the mouse, so your on-screen behavior stays consistent during the call.

**Strengths:** Purpose-built for coding interviews with full LeetCode-style coverage and syntax highlighting; Desktop app design avoids the screen-sharing blindness of browser-extension copilots; Mobile mode works without installing anything, just a phone browser; Free trial requires no credit card and includes the full feature set

**Limitations:** Using an AI copilot in a proctored interview may violate employer or assessment-platform rules; The monthly single-loop plan is costly if a job search spans several months; It requires the desktop app for screenshot and hotkey features, so mobile alone is more limited

## 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
