## 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

## Plerdy

Plerdy is a conversion rate optimization suite built around a blunt premise: your site may look fine while quietly losing money. It bundles the tools usually bought separately — website heatmaps, session replay, error tracking, traffic value analysis, ecommerce analytics, funnel analysis, event tracking, pop-ups, visitor feedback, A/B testing and SEO monitoring — into a single plan so you can diagnose why visitors do not buy and then prove that the fix worked. Setup is quick, via a single script or through Shopify, WordPress and Wix, and the platform is GDPR-ready.,The angle that distinguishes Plerdy from a conventional analytics tool is the connection it draws between traffic sources and user experience problems. Its dashboard links campaigns directly to UX issues, so instead of only celebrating clicks you can see which ads generate rage clicks, filter by landing page and spot wasted ad budget right away. A live demo illustrates the idea: an ad with no buyers, a dead Add to cart button on iPhone, a product photo everyone clicks that does nothing, and shipping costs that only appear at checkout, together costing a sample store thousands per month.,Around that core, Plerdy adds the tools to act. Pop-ups capture leads, feedback widgets ask visitors why they did not buy, and the free A/B testing tool lets you test a change on live traffic and pick the winner. On the search side, daily site audits and Search Console alerts keep technical SEO healthy, while the SERP checker compares your page with Google's top ten. Free Chrome extensions for SEO and UX analysis let you audit any website in one click without deploying the full script. A newer MCP integration lets you ask your Plerdy data questions in plain language through Claude and ChatGPT.

**Pricing & Plans:** Plerdy offers a free 14-day trial, free Chrome extensions and a free A/B testing tool, with paid plans bundling the full tool set instead of separate subscriptions. Some modules, such as the SERP checker, are sold as add-ons.

- **Heatmaps and session replay:** See clicks, scroll depth and attention on every page, plus watch real sessions to identify exactly where visitors get stuck and abandon.
- **Traffic value and ecommerce analytics:** Connect campaigns and landing pages to revenue, orders and AOV, and find the specific page or channel that is losing you sales.
- **Error tracking:** Spot JavaScript errors, 404s and 5xx responses that break the checkout before they cost you conversions.
- **Pop-ups, feedback and A/B testing:** Run targeted pop-ups, visitor feedback surveys and A/B tests on live traffic to fix leaks and prove the change worked.
- **SEO checker and monitoring:** Daily site audits, Search Console alerts and SERP comparison against Google's top ten keep your search visibility on track.

**Strengths:** A dozen CRO and SEO tools bundled in one plan rather than five separate subscriptions; Dashboard connects traffic sources directly to UX problems and wasted ad spend; Free 14-day trial, free A/B testing tool and free Chrome extensions lower the entry cost; Strong review scores on G2 (4.7/5, 300+ reviews) and Capterra (4.9/5)

**Limitations:** The breadth of tools means a longer setup and more documentation than a single-purpose analytics script; Some reviews mention the volume of configuration options can be overwhelming at first; Advanced capabilities like SERP checking are add-on modules rather than included in the base plan
