Frequently Asked Questions

How long does it take to learn Brazilian Portuguese?

Most learners reach conversational level (B1) in 6-12 months with consistent daily practice. Decko's spaced repetition system helps you retain vocabulary efficiently, so you spend less time reviewing and more time learning new material.

What is spaced repetition and how does FSRS work?

Spaced repetition shows you flashcards just before you would forget them. Decko uses FSRS (Free Spaced Repetition Scheduler), which requires 20-30% fewer reviews than traditional systems like Anki's SM-2 algorithm, while achieving the same retention rate.

Is Decko better than Anki for learning Portuguese?

Decko is built specifically for language learning with features Anki lacks: built-in conjugation drills for 140+ Portuguese verbs, AI-generated example sentences, travel phrase guides, and a mobile-first design. It uses the FSRS algorithm, which is more efficient than Anki's default SM-2.

Can I learn Portuguese on my phone?

Yes. Decko is designed mobile-first for learning on the go. Study flashcards, practice verb conjugations, and listen to pronunciation anywhere. All features work in the mobile browser with no app download required.

What Portuguese dialect does Decko teach?

Decko teaches Brazilian Portuguese, which is spoken by over 200 million people. All vocabulary, example sentences, and conjugation drills use Brazilian pronunciation and grammar conventions, including the voce form rather than tu.

Is Decko free?

Yes, Decko has a free tier with access to core flashcards, conjugation drills, and spaced repetition. Pro plans add unlimited AI-generated sentences, advanced statistics, and additional deck content.
