Learn languages without limits

Grammar-first lessons, an AI conversation partner, and real-world scenarios. No energy gates. No subscriptions. Just learning.

Built for people who want to actually understand the language
The status quo

Tired of being locked out of your own learning?

Energy gates that stop you mid-lesson

Run out of hearts and you're locked out until tomorrow. Your motivation shouldn't have a bedtime.

Grammar taught through random, useless sentences

Memorising "the owl drinks milk" teaches you nothing about how the language actually works.

Subscriptions that never end

Paying every month forever for a language you're trying to learn feels like a trap, not a service.

Fluxa was built to fix every one of these.

What's inside

Everything you need.
Nothing you don't.

No energy gates

Learn as much as you want, whenever you want. No timers, no hearts, no limits. Your pace, always.

Grammar first

Every question explains the rule before you answer, so you understand why — not just what.

AI conversation

Practise real conversations with Sofia, your AI partner. She speaks back, corrects your grammar, and never judges.

Voice and audio

Hear every word and sentence in a native voice. Build real pronunciation from day one.

CEFR tracking

Know exactly where you stand. Fluxa maps your progress to the internationally recognised A1–C2 levels.

Streak protection

Life happens. One free streak save a week means missing a day won't undo your hard work.

The lineup

Twelve languages. Your journey starts here.

Spanish and French are always free. Unlock any other language for a one-time payment — no subscription, never expires.

What learners are saying

Finally an app that explains why sentences are built the way they are. I learned more grammar in one week with Fluxa than in months with other apps.

Learning Spanish

The AI conversation feature is incredible. Sofia corrects my French in real time and I can hear the right pronunciation immediately.

Learning French

No energy limits is a game changer. I can sit down for an hour of Japanese practice without being told to come back tomorrow.
