Maintain the orbit
Smart scheduling brings words back just before you forget, until constellations lock in for good.
The Academy
Beyond the flashcards there's a real course: chapters of guided lessons that teach, then drill, one idea at a time. The Spanish course is live and free today, with Norwegian in active development.
Guided lessons
Chapters that build in order, from Presentaciones to Comida y compras. Every lesson presents new words and sentences with native audio, then practises them across ten exercise types.
Grammar, explained
Ser versus estar, formal and informal address, gendered articles. Plain-English rules with tables and worked examples — not a wall of conjugations to memorise.
Checkpoints & exams
Periodic checkpoints re-test what earlier chapters taught, and a timed level exam closes out the level. Miss something and you're pointed back to the exact lesson it came from.
Nova, your practice partner
Nova is an AI conversation partner for practising what the lessons taught — roleplay chats, translations and word explanations. It never scores or assesses you; that's what the exercises and exams are for.
Galaxies to Explore
Spanish, French and Norwegian have full vocabulary galaxies you can study today. The guided lesson course is live for Spanish so far.

Frequently Asked Questions
How does Nebulingo use AI?
Nova, our conversation co-pilot, is an AI partner for practising your target language — roleplay chats, translations and word explanations. We also use AI as an authoring tool: dictionary entries, example sentences, lesson content and audio start as AI drafts, which then go through automated quality checks and human review before anything is published.
Nebulingo's AI never assesses, scores, certifies or makes decisions about you. Review scheduling uses FSRS, a deterministic spaced-repetition formula; exercise answers are checked by simple text comparison; pronunciation practice runs entirely in your browser. Full details are in our Privacy Policy.
Is Nebulingo really free?
Yes. Every language, all four study modes, native-voice audio and daily Nova practice are free forever — no trial, no card required. Pro ($4.99/mo or $39.99/yr) adds higher Nova limits, enhanced streak freezes and premium lessons, and helps keep Nebulingo independent and ad-free.
Which languages can I learn?
Spanish, French and Norwegian are fully charted and ready to study today. German, Italian, Portuguese and Dutch are being charted and will follow. Your progress, streak and vocabulary galaxy are tracked separately per language, so you can learn more than one at once.
How does the spaced repetition work?
Each word is a star in your galaxy. Nebulingo uses FSRS — a modern, open spaced-repetition scheduler — to bring a word back for review right before you're likely to forget it. Get it right and the interval grows; slip and it returns sooner. Over time, well-remembered words lock into permanent constellations.
Do I need to install anything?
No — Nebulingo runs in your browser on any device. It's also an installable web app (PWA): add it to your home screen for a full-screen, app-like experience with offline-friendly caching. There's nothing to download from an app store.
Can I cancel Pro anytime?
Absolutely. Cancel with one click whenever you like and you keep Pro access until the end of your current billing period — after that you simply return to the free plan. Your learning progress is always yours and never expires. See our Refund Policy for details.
