## BLACKBOX.AI (Chrome Extension)

BLACKBOX.AI is aimed at developers who constantly interrupt their work to look things up. Instead of leaving a page, copying code into a chat window, and coming back, the extension opens a side panel or popup where you can ask coding questions and get answers and suggestions in real time.

The extension covers four main workflows as described by its developer. Code Chat answers coding questions on demand; an Include Context option lets you ask questions about the page you are currently viewing; GitHub integration adds a Code Chat button above code you are reading on GitHub so you can question that specific file; and an OCR mode triggered with CTRL+E on Windows or CMD+E on Mac lets you select any region of the screen and paste the recognised text elsewhere.

It is a free extension with around 300,000 users, and the listing is unusually transparent about the developer declaring that it does not collect or use your data. The trade-off is quality perception: with 1.2K ratings the average sits around 2.7 out of 5, so expect a convenient but uneven experience rather than a polished IDE-grade assistant. It works best as a lightweight companion to the web-based BLACKBOX.AI service rather than a replacement for a full editor plugin.

**Pricing & Plans:** The Chrome extension is free to install. Paid tiers exist on the BLACKBOX.AI web platform itself, but the extension's own store listing is free.

- **Code Chat in your toolbar:** Open the extension with a click or a keyboard shortcut and ask coding questions, receiving answers and suggestions in real time.
- **Use the current page as context:** Activate Include Context to ask questions about documentation, Stack Overflow answers or any page you are reading.
- **GitHub Code Chat button:** When viewing code on GitHub, a Code Chat button appears above the file so you can query that specific code directly.
- **Image-to-text OCR:** Press CTRL+E (Windows) or CMD+E (Mac), select a screen region, and paste the extracted text wherever you need it.
- **Small footprint on Chrome:** Roughly 2 MB in size, available in English and Korean, and the developer declares no collection or use of your data.

**Strengths:** Free to install and light on browser resources; Combines code chat, page context, GitHub integration and OCR in one extension; Developer explicitly declares it does not collect or use your data; Large install base of roughly 300,000 users

**Limitations:** User rating is modest at about 2.7 out of 5 from 1.2K ratings, so experiences vary; The store description is thin and largely a walkthrough, with little detail on underlying models; Advanced capabilities generally expect an account on the main blackbox.ai platform

## 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
