Frequently asked questions
Is Vietnamese hard to learn?
Good news: Vietnamese uses the Latin alphabet (quoc ngu), so there's no new script to learn, and the grammar is simple (no conjugation, no gender, no plurals). The real challenge is the 6 tones: the same word changes meaning depending on the tone. OpiFluent has you practicing tones from day one, with an AI that catches your tonal mistakes.
How long to learn basic Vietnamese?
With 15 to 20 minutes a day, you can reach a basic conversational level (A1-A2) in 4 to 6 months. Since the alphabet is already familiar and the grammar is simple, most of your energy goes into tones and pronunciation, which speeds things up once it clicks.
Should I learn Northern or Southern Vietnamese?
The Hanoi (Northern) and Saigon / Ho Chi Minh City (Southern) accents differ in speech. OpiFluent lets you practice both and prepares you to understand locals wherever you live, whether it's Da Nang, Saigon or Hanoi.
Is it really free?
Yes. The free plan includes daily AI conversations, vocabulary exercises, quizzes and pronunciation practice, no credit card required. The Pro plan unlocks unlimited conversations, voice mode and every situation.
Is it suitable for absolute beginners?
Absolutely. The A0 level starts with greetings, the 6 basic tones and numbers. The AI tutor adapts its vocabulary and pace to your level. You learn to speak about real situations from the start, not word lists.
