Build mastery and confidence with Camille, your virtual French pen-pal.

I've been there too!
Salut ! I'm Nicole 👋🏼
I've spent 15 years trying to learn French.
Many years ago, my French mother-in-law had improved her English through a pen-pal exchange. It worked because it gave her time to craft thoughts, learn real idioms, and absorb personalised language.
Why didn't a modern version of that exist for French?
So, my husband Olivier, a software engineer, built Camille for me, bringing this timeless pen-pal method into the digital age.
And it works! I've used Camille for six months, and while I still make mistakes, my French has never been better.
We're now sharing Camille because we're confident it can help others too, and we'd love for you to give it a try.
Bon courage !

How it works
01
Camille starts the conversation by emailing you, so you're building vocabulary from the first message.
02
Reply to Camille in French, as best you can, using vocabulary relevant to your life. Mistakes are normal — there is no need to be perfect!
03
Camille responds with a handful of corrections. These then become short, tailored exercises that help you communicate like a native speaker.
04
Camille resurfaces exercises just as you are about to forget them, reducing your forgetting curve, and boosting long-term language retention.
05
Understand how you're improving with real-time metrics and weekly progress reports.
enhanced retention
Writing to Camille trains your brain to retrieve and build sentences, closing the gap between learning new words, and actually using them.
This is called the "output hypothesis" — a synthesis of 12 studies found language learners who used new words in output tasks retained significantly more vocabulary than those who only read them.[1]
65% stronger recall
Communicating about your life, hobbies, and thoughts significantly improves vocabulary retention.
This is the "self-reference effect". In a study of foreign-language learners, words tied to a personal sentence were recalled about 65% more often a week later than words learned by straight translation practice.[4]
improved accuracy
Writing to Camille gives you time to think. Your first attempt need not be perfect — take as long as you need to consider your grammar, look up new vocabulary, and edit your message.
This is known as the "monitor hypothesis": given time to edit their own writing, language learners produce significantly more accurate sentences than when writing under time pressure.[2]
31% better recall
Camille tests you at scientifically optimal intervals. This flattens your "forgetting curve" and locks the correct French into your long-term memory.
Reviewing content at optimal intervals is called "spaced repetition", and is highly effective at interrupting memory decay before it happens. In a 2009 study, recall accuracy was 31 percentage points higher than cramming, even with the same total study time.[5]
better learning
Every exercise targets a past mistake, ensuring you focus on the areas that need your attention.
A meta-analysis of 33 studies found feedback targeted to a language learner's own mistakes produced meaningfully stronger, longer-lasting gains than generic grammar drills.[3]
35% more effective
Working with Camille only takes 10 minutes a day. Writing and revising a little, often, is what builds mastery that lasts.
Cognitive scientists call this "distributed practice". One study of French learners found that spacing practice into short, daily bursts improved long-term vocabulary retention by up to 35%, compared to studying the same total time in one long session.[6]
Camille is free to try for two weeks, no credit card required.
If you love it (and we hope you do!), you can choose to continue for $10 per month, or $8 per month, when paid annually.
We provide a no-obligation free trial because we believe you shouldn't have to commit to something before you know that it's right for you.
Camille works from early conversational French (A2) through to fluent, near-native French.
To get started, you'll need enough French to read a simple message and attempt a reply (no worries if it's full of mistakes!).
From there, Camille adjusts to you: every message is pitched just beyond your current level, so you're always stretched, but never overwhelmed.
Camille is not designed for absolute beginners. Nor is it designed for passing formal exams; if your primary goal is to study for a specific test, other resources might be a better fit.
Absolutely. Every correction and exercise comes with a playback feature — a native French voice pronounces the phrase or sentence, so you can hear it and repeat it back.
This builds a bridge between what you can read and write, and what you can understand and speak.
Because Camille uses neuroscience to optimise your learning, you should start seeing results with just 5-10 minutes of daily practice.
This approach, known as "Distributed Practice", is supported by evidence. By focusing on small, regular intervals, you can improve long-term vocabulary retention by up to 35% compared to longer, infrequent study sessions.[6]
Camille uses AI to simulate a real-world reading and writing experience, providing personalised feedback and exercises tailored specifically to your vocabulary.
The data you share with Camille is never used to train or improve AI models.
See how we use AI to support your learning (and protect your data).
You absolutely can! The problem is that ChatGPT gives you corrections; it doesn't make sure you learn from them. After a few weeks, your chat history is a graveyard of mistakes you'll never revisit.
The difference is that Camille turns every mistake into a future exercise, bringing it back days or weeks later, until you've learned the correct French.
Camille also removes the friction of deciding what to do: no prompting, no planning, no wondering what to practise. Your next piece of correspondence simply arrives in your inbox.
The honest truth: If you already have the discipline to maintain your own spaced-repetition decks, track your mistakes, and journal in French every day, you probably don't need Camille. But if you want the benefits of that rigour without having to manage the system yourself, then Camille is for you.
We take handling and securing your data very seriously. Your information is stored on enterprise-grade infrastructure, and all your data is fully encrypted at rest.
We are strictly committed to your privacy: we never share your data with third parties and your personal conversations and practice data are never used to train AI models.
Camille was built by Olivier (a French speaker and software engineer) and Nicole (a French learner). You can learn more about our story on our about page.
