What's new in Apostrophe·: a web app, synced progress and adaptive dictations

Hi everyone,

Apostrophe· is a French dictation app. You listen to a sentence, type it, and each mistake is marked word by word with the grammar rule that explains it. The comparison is done by our own code; AI only writes the explanation once a mistake has been found.

Here is what shipped this autumn.

A web app. Apostrophe· now runs on a computer at apostrophe-app.fr/app, with nothing to install. Same account and same progress as on the phone, sign-in by email or with Apple, buttons for accented letters if your keyboard isn't French, and a page that shows your progress. The idea came from a school whose pupils have no phones but do have classroom computers.

Progress that follows you. Once you're signed in, your dictations and your streak sync between iPhone, Android and the web.

Dictations that adapt. When you ace every sentence, the next ones get longer; when you struggle, they get shorter. The app can also suggest moving up or down a level, and you decide.

PDF export. A corrected dictation can be saved as a PDF, handy for a teacher or a parent.

iPhone Duo. The home and correction screens use a split layout on the new foldable.

A free Chrome extension. Paste a text and it flags the most common French mistakes, each with a link to its rule. No account needed.

Free dictations on the website. Each level has dictations you can do online, checked word by word, plus texts to print: apostrophe-app.fr/dictee

The interface is in French, English, Spanish, German and Italian, levels go from A1 to C2 for learners, and there are two natural voices, one from France and one from Québec.

If you're learning French, which mistake keeps coming back when you write? It helps me decide what to build next.
