SEE IT IN ACTION

A closer look at what you actually get

Real screenshots from inside the app — this is exactly what you see once you sign in.

NEXUS inventory grid — wallpapers, cursors, fonts, badges, effects with rarity tags and Equip buttons

Shop, inventory, and customization.

Buy fonts, wallpapers, cursors, effects, and badges with credits you earn studying — then equip them from one organized inventory grid. Real customization, not stickers.

NEXUS Command Center dashboard — stats, daily goals, and 8 AI tool cards (Live Vision, English Generator, Quick Quiz, Math Visualizer, Science Simulator, History Timeline, AI Flashcards, Debate Practice)

Every AI tool, one launcher.

The Command Center is where you fire off Live Vision, generate essays, run a Quick Quiz, visualize math, simulate experiments, build timelines, or build a flashcard deck — all from one panel. Tutor Mode guides you instead of just handing over answers.

NEXUS Sprite companion chat window — avatar, online status, intro message, and chat input

A companion that boosts your study.

NEXUS Sprite — a real-time study buddy you can link to whatever you're working on. Encouragement, hints, and a calm presence on long sessions so the work doesn't feel like a grind.

WHY NEXUS

Why not just use ChatGPT?

Honest answer: you can. The difference is NEXUS is built to teach — its Tutor Mode coaches you to the next step instead of handing over the answer, wrapped in tools made for studying, not a blank chatbot box.

FAQ

Common questions

How does pricing work?

You build your own plan — pick only the modules you want at $2/month each (minimum 4, so $8/mo). The 8 modules are Math, Science, English Aid, Social Studies, Smart Notebook + Focus, AI Command Center, Shop + Companion, and Competition. Want it all? All 8 is $16/mo. Add or drop modules anytime from Settings → Manage My Plan. Right now it's all free while we're in open beta.

How does Tutor Mode actually teach?

Tutor Mode never just hands you the answer. It first explains the concept behind the problem — what's going on, why this kind of problem exists, what tool you'd reach for — then asks you to take the first step yourself. One step at a time, with feedback after each one. By the time you've worked through 2–3 problems together, the pattern actually sticks. Pro subscribers can flip to Casual Mode (instant answers) for quick checks.

How does Live Vision work — and is it allowed?

Live Vision reads whatever's on your screen — a textbook PDF, a worksheet, a graph, your own notes — and helps you understand it: it explains the concept and walks you through the steps so you can solve it yourself. It works with any web-based material because it reads the screen, not a specific platform.

Use it honestly. Live Vision is a study aid, not an answer key. Always follow your school's rules on AI assistance, and don't use it on graded tests or quizzes where outside help isn't allowed.

Do I need my own OpenAI key?

Nope — AI is built in. Just create an account and the AI features work right away through NEXUS's hosted AI; no keys, no setup. If you'd rather use your own OpenAI key (for unlimited usage), you still can — paste it in Settings → AI and NEXUS uses that instead.

Can I cancel? What if I clear my browser?

Cancel anytime from Settings → Subscription. You keep access until the end of the current billing period — no retention emails, no hoops.

What's the "backup file" you'll ask me to download?

Your account syncs to the cloud automatically when you sign in, so you can pick up on any device and clearing your browser won't wipe you out. As an extra local copy, you can also download a small .json backup (Settings → Data) — your username, progress, credits, inventory, and equipped items, with no password and no executable code. Belt and suspenders: cloud sync for convenience, the file for total control.

Grade Calculator

Know where you stand in every class — and what you need to hit your goal.

What this is & how to use it

A running average for each class so you always know your grade — and exactly what you need on the next assignment to hit your goal. It's a personal planner, not your school's official gradebook.

  1. Add a course (e.g. "Biology") and, optionally, a target grade — the % you're aiming for.
  2. Add each grade as you get it: a score out of 100 and an optional weight (so tests can count more than homework). Leave weights blank for a plain average.
  3. NEXUS shows your current %, letter grade, and 4.0 GPA, and — if you set a target — the score you need next to reach it.

Tip: weights don't have to add up to 100 — they're normalized automatically. Stuck? Hit 🎓 Ask Tutor.
