Clio is the friendliest way to actually learn the AI tools everyone's talking about. Most AI apps explain prompting and then quiz you about it. Clio makes you build the prompt. The Prompt Lab hands you a real job, and you assemble the prompt line by line from tap-tiles, then Clio grades what you built against a rubric and shows you what a pro would have sent. WHICH AI SHOULD I USE? Pick the job, from writing and coding to research, images or video, and Clio names the model to use today and why, with two good alternatives. CERTIFICATES Finish a course and get a certificate with your name on it, ready to share. RUN YOUR PROMPT, ON DEVICE Clio Pro runs the prompt you built on your own device, offline, next to the pro version. Requires Apple Intelligence. THE PROMPT LAB - 10 real briefs: a launch email, a bug triage, meeting notes, CV bullets, a product shot, a voiceover, an agent hand-off and more - Build role, context, task, constraints and format from 200 tap-tiles. No typing, ever - Scored out of 100, line by line, with the reason each choice was worth what it was worth - Keep every template you earn in your Library DAILY QUESTIONS Five questions, about a minute. Drawn from everything you have studied plus something new, so the streak survives a day with no time for a lesson. PATHS Pick a goal instead of a course. Get hired with AI, Ship a product with AI, Run a team with AI, or Create with AI, each one a route through the catalogue with your next step always in front of you. WHAT YOU'LL LEARN - The AI Model Guide: GPT-6 Astra, Claude Opus 5.5 and Fable 5.1, Gemini 3.8, Grok 4.7 and how to pick the right model - Prompting Fundamentals: the one skill behind every AI tool (free) - Claude, ChatGPT, Gemini, Grok and DeepSeek: get great results in chat, work and research - ElevenLabs voice, Nano Banana images, Higgsfield video: hands-on creative AI - Agentic AI and Claude Code: what agents actually do, and how to hand work over safely - 21 courses, 109 lessons, 921 exercises, updated for the newest AI models 200+ HAND-CRAFTED ILLUSTRATIONS Every lesson is illustrated in Clio's bold paper-and-ink style, so tricky ideas click at a glance. PLAY A MISSION EVERY DAY - A real scenario, four ways to prompt it. Pick the best call - Then see THE PRO MOVE: the exact prompt an expert would send, and what came back - Boss missions on Sundays for 2x XP LEARNING THAT STICKS - Illustrated explainers with weak vs strong prompt examples - Instant feedback plus 330+ "Good to know" facts - Missed questions quietly come back until you get them right - Recap quizzes, streaks and a friendly mascot named Clio LEVEL UP FOR REAL - Earn XP from lessons, briefs, missions and daily questions - Climb 30 levels, from AI Curious to AI Strategist - Collect achievements and 100+ pro prompts SIRI AND SHORTCUTS Ask for today's mission or your streak without opening the app, and start the daily questions from the Action button. FREE TO START The full Prompting Fundamentals course, the first lesson of every course, daily missions, daily questions and AI news are free. CLIO PRO Unlock every course, lesson and recap quiz, and run your own prompts on device. Subscribe, or buy it once: - Monthly: $4.99 per month, after a 7-day free trial - Yearly: $29.99 per year, after a 7-day free trial, which works out at $2.50 a month - One-time: $59.99, paid once.

About

Calculus & Probability Lab

Features
Read full description

Calculus & Probability Lab turns two of the hardest STEM subjects into something you can see, touch, and drag with your finger. Instead of static graphs in a textbook, every derivative, integral, and probability distribution becomes a real 3D object you orbit, zoom, and reshape live. Whether you're in AP Calculus, a first-year college calculus or statistics course, or just relearning math you forgot, this app trades memorized formulas for visual intuition: drag a point along a curve and watch its tangent-line slope update instantly, or watch a histogram built from real dice tosses close in on the bell curve as you roll. FUNCTION LAB — 3D VISUALIZER • 22 function families: lines, parabolas, cubics, quartics, sine/cosine waves, exponentials, natural logs, reciprocals, square roots, Gaussian bumps, logistic S-curves • Genuine z = f(x, y) surfaces — paraboloids, saddles, Gaussian hills, ripples, sphere caps, cones, tilted planes, monkey saddles, egg-carton surfaces, twin peaks — drag to orbit, pinch to zoom • Live tangent-line overlay — move a point along any curve and watch the exact derivative f'(x) recompute in real time • Riemann sum overlay — slide from 1 to 60 rectangles and watch the sum converge to the exact definite integral • Every formula is closed-form and exact — no approximation, no drift PROBABILITY LAB — PHYSICS DICE • Toss physics-simulated dice and build a genuine empirical histogram, roll after roll • Scenarios span dice-sum outcomes, coin-flip binomial trials, and Poisson arrival processes • Overlay your empirical results against the exact theoretical distribution on the same chart • Watch the Central Limit Theorem happen live: enough trials and the histogram closes in on the normal curve • Track empirical mean against theoretical mean at every roll LEARNING PATH — 4 WORLDS, ~50 LESSONS • World 1, Functions & Limits: what a function is, families of functions, slope, one- and two-sided limits, continuity, average vs. instantaneous rate of change, exponentials and logs • World 2, Derivative Lab: the derivative as slope, power/product/quotient/chain rules, higher derivatives, tangent planes and partial derivatives, critical points, related rates, optimization, the Mean Value Theorem • World 3, Integral Lab: area under a curve, Riemann sums, the definite integral, antiderivatives, the Fundamental Theorem of Calculus, net change, average value, area between curves, volumes of revolution, improper and numerical integration • World 4, Probability & Distributions: sample space and events, combining probabilities, the two-dice sum, random variables, expected value, binomial and Poisson models, the normal curve • Every lesson deep-links straight into the matching 3D lab, so theory and visualization reinforce each other AI TUTOR • Tap Explain on any surface, formula, or dice distribution and get a plain-language breakdown of exactly what's in front of you — your specific coefficients, your specific slope, your specific mean and standard deviation, not a generic textbook definition BUILT FOR REAL STUDY, NOT JUST BROWSING • Progress tracking across every world and lesson, so you always know where you left off • A limited number of dice rolls each day on the free tier; upgrade to roll without limits, unlock every function family and 3D surface, every lesson, and the AI tutor • A clean, dark, distraction-free interface built for a late-night study session, not a cluttered graphing-calculator UI • Monthly and Annual plans, with a 3-day trial on Annual — cancel anytime in your account settings Calculus and probability are usually taught as two separate walls of formulas to memorize before an exam. Calculus & Probability Lab treats them as one connected, visual subject — build the intuition once, and the formulas stop needing to be memorized at all.
