## Brilliant

Brilliant takes a different approach to learning: rather than watching long videos or reading dense textbooks, you build understanding by solving interactive problems. Lessons break big ideas down into small visual steps, so concepts in algebra, calculus, statistics, logic and Python become intuitive. The platform is designed for self-paced learners from roughly middle-school level up to college and beyond, and it adds a new AI tutor called Koji who asks guiding questions and sketches on screen to help you find answers yourself.

Beyond pure math, Brilliant covers computer science fundamentals, programming, data analysis and how modern AI actually works, including neural networks, tokenization and model reasoning. Each track uses mastery assessments that adapt to your level, revisiting weak spots and serving targeted practice so progress is measurable rather than vague. Real-world examples, such as image filters or password security, connect abstract ideas to everyday technology.

The platform is also used by schools and families. It is accredited by ACS WASC, certified under the kidSAFE/COPPA program, and offers classroom and teacher programs so educators can assign adaptive lessons and homework. For individual learners, the app is available on web and mobile, with progress syncing across devices.

**Pricing & Plans:** Brilliant uses a freemium model: a limited free experience is available, while a Premium subscription unlocks the full course library and unlimited practice. Annual plans are the cheapest per month, and there are separate school/classroom plans.

- **Interactive problem-based lessons:** Learn math, science, CS and AI through short, visual exercises that build intuition step by step rather than passive video watching.
- **Koji AI tutor:** A visual, interactive tutor that works on a shared canvas, asks guiding questions and gives hints without simply revealing the answer.
- **Adaptive mastery assessments:** Quizzes and reviews adapt to your level, tracking what you have mastered and resurfacing topics that still need work.
- **Coding and CS foundations:** Write and run real code to learn programming logic, algorithms, data structures and debugging skills relevant to the AI era.
- **Courses for schools and families:** Accredited classroom programs let teachers assign adaptive lessons, with kidSAFE/COPPA-certified privacy protections.

**Strengths:** Hands-on, visual format makes abstract concepts easier to grasp; Access to the Koji AI tutor that guides rather than gives away answers; Accredited and kidSAFE/COPPA certified, suitable for schools and families; Works across web and mobile with syncing progress

**Limitations:** Full course library requires a paid Premium subscription; Not a replacement for formal instruction or credentials; Some advanced or niche topics are not covered deeply

## Claude & Codex Plugins

Claude & Codex Plugins solves a very practical problem for people who live inside agentic coding CLIs: discovering what is actually installable. Rather than a hand-curated editorial list that goes stale, the site sweeps GitHub every day looking for repositories that expose a `.claude-plugin/marketplace.json`, `.claude-plugin/plugin.json`, `.codex-plugin/plugin.json` or `.agents/plugins/marketplace.json` manifest, then reads those manifests exactly the way Claude Code and Codex read them. The result is a large, machine-verified catalog — currently hundreds of thousands of plugins drawn from tens of thousands of marketplaces — sorted by stars, trend and category.

Each plugin page focuses on the two things developers actually need before typing a command: the precise install lines for both Claude Code and Codex, and an honest inventory of what gets added to the agent. That inventory breaks down into skills, slash commands, subagents, hooks and MCP servers, so you can see at a glance whether a plugin is a lightweight prompt pack or something that starts local processes and fires event hooks. Because plugins can execute code, that transparency matters.

The site is built by the team behind AI Architectures and is explicitly unaffiliated with Anthropic and OpenAI. It is free to browse and free to submit a repo — pasting a GitHub URL triggers an instant manifest check that reports anything that would break an install, making it useful for plugin authors as well as consumers.

**Pricing & Plans:** Free to browse, search and use. Submitting or checking a plugin repository is also free. The site is operated commercially through an optional featured/paid listing program and a related cloud desktop product, but no fee is required to view the catalog or list a plugin.

- **Daily GitHub manifest sweep:** The index is rebuilt every day by scanning public repositories for Claude Code and Codex plugin manifests, so new releases appear without anyone hand-editing a list.
- **Copy-ready install commands:** Every plugin page shows the exact two-line install sequence for both `claude plugin` and `codex plugin`, including the marketplace add step.
- **Full contents disclosure:** Each listing enumerates the skills, slash commands, subagents, hooks and MCP servers it installs, so you know what will run inside your agent before you commit.
- **Instant manifest checker:** Paste a public GitHub repo and the site validates its manifest the way the CLIs do, flagging problems that would break installation.
- **Sorting by stars, trend and category:** Browse by popularity, weekly trending or categories like productivity, development, security, design and research to find relevant plugins quickly.

**Strengths:** Catalog is generated from real GitHub manifests rather than editorial picks, so it stays current and verifiable; Shows install commands for both Claude Code and Codex side by side; Discloses hooks and MCP servers, which is the information that matters for safety; Free to browse and free to submit, with an immediate manifest validation on submit

**Limitations:** Coverage depends entirely on repos being public and correctly structured, so private or malformed plugins never appear; The sheer volume of listed plugins can be overwhelming without narrowing by category or star count; Star counts dominate the default rankings, which can bury useful but niche plugins
