## 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

## T3 Code

T3 Code is an open-source application for developers who juggle more than one AI coding agent. Instead of switching between terminals, editors and vendor dashboards, it provides one surface where threads with Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok can run side by side. Critically, the project does not resell model tokens: you plug in the credentials and subscriptions you already have, so your existing plan and quota remain yours. Models can even be switched mid-thread, letting you move a task to a different harness without losing conversation context.

**Pricing & Plans:** Free and open-source. There is no T3 Code subscription; you bring your own existing Claude Code, Codex, Cursor or similar subscription and pay those vendors directly.

- **Multi-Agent Orchestration:** Run Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok sessions side by side in one workspace.
- **Bring Your Own Subscription:** No resold tokens or quota caps — connect the credentials and plans you already pay for, and switch models mid-thread.
- **Git and PR Workflow:** Manage branches, automate commits and pushes, and handle pull requests with inline diff review before accepting changes.
- **Forkable and Self-Hostable:** Open-source and MIT licensed, so you can run it on your own infrastructure and modify it for your team.
- **Desktop and Mobile Access:** Available on macOS, Windows and Linux with iOS, Android and browser connect options for remote machines.

**Strengths:** Free and open source with no vendor subscription for the tool itself; One interface for several major coding agents instead of scattered terminals; Bring-your-own-subscription model with no token reselling or quota caps; Mobile and browser access plus Git, diff review and PR automation built in

**Limitations:** Requires your own paid agent subscriptions to be genuinely useful; Self-hosting and configuration are your responsibility, with community rather than vendor support; Rapidly evolving project means features and stability can shift between releases
