Grammar theory before every drill. Practice you type yourself. And a French tutor that remembers your last lesson.
After a negative, du / de la / des become de.
Je ne bois pas de café.I do not eat bread.
Bonjour ! I'm Piaf. Ask me anything about French below and I'll show you how I teach.
Pick a question and watch how Piaf explains it. No account needed.
A quick walkthrough of the method, from theory to practice to conversation.

Ask why du becomes de in a negative sentence and Piaf answers from the exact module you are on, in plain English. Then take it On Stage: live roleplay conversations where you order coffee and survive small talk with an AI partner.
Other apps hand you 'Je suis un homme' and hope you deduce why suis changes. Piaf gives you the rule, then the drill. Every module opens with grammar theory and vocabulary in context before a single exercise begins.
Tapping the right picture requires zero production. In the Atelier you write the sentence yourself: fill-in-the-blanks, typed translations, word-ordering drills. Typos are tolerated, and every wrong answer comes with an explanation.
Every time Piaf clarifies a grammar point, it can save the rule to your personal Notebook, a study companion that builds itself while you learn. Export it to PDF and revise offline.
