## 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

## 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
