## 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

## Ghost Engineer

Ghost Engineer positions itself as an interview-time tool rather than an interview-preparation course. Instead of grinding practice problems, you launch the app before the call, keep it running in the background, and capture any question that appears in the shared editor or video chat. The app then produces a solution in the language of your choice, plus optimization notes and a short talk track you can read aloud.

The design goal is discretion. There is no floating overlay and no window that shifts focus, so nothing appears in a screen share. It works alongside common interview platforms such as CoderPad, CodeSignal, HackerRank, and LeetCode, and it can answer in the same language you wrote your prompt in. Supported languages include Python, JavaScript, TypeScript, Java, Kotlin, Swift, Dart, C#, C++, Go, Rust, Ruby, PHP, SQL, R, HTML/CSS, Bash, Perl, Julia, Scala, and MATLAB.

It is a paid desktop product with a free demo mode, an internet connection requirement, and macOS/Windows builds. Because it is explicitly built for use during a proctored or live evaluation, the ethical and contractual responsibility for using it rests entirely with the candidate and the rules of the hiring process.

**Pricing & Plans:** Free demo mode to test the workflow, then subscription tiers: $79.99 per month or $199.99 for three months (roughly 15% savings). No credit card is required to start the free version.

- **Screen-share safe operation:** Runs without overlays, dock icons, or focus-stealing windows so it does not show up visibly during a shared screen.
- **Solution plus talk track:** Returns a complete working solution together with complexity analysis and explanation points you can say out loud.
- **20+ language coverage:** Handles Python, Java, C++, Go, Rust, TypeScript, SQL, and many more, with responses in the language you prompt in.
- **One-hotkey capture:** Screenshot any question from any editor or chat window and get an answer back in seconds during the round.
- **System design and optimization help:** Goes beyond passing tests by suggesting better data structures, lower complexity, and follow-up improvements.

**Strengths:** Purpose-built for live rounds rather than practice, so the workflow is optimized for speed; No overlay and no focus shifts, which reduces the risk of an obvious visual giveaway; Answers arrive with explanation points, not just code, which helps you keep talking; Supports a very wide set of programming languages in one desktop app

**Limitations:** Requires an internet connection, so it cannot be used offline or on locked-down machines; No student pricing and no free tier beyond a limited demo mode; Using assistive tools during proctored interviews may violate employer or platform rules, so risk sits with the user
