The science is remarkable.

is built on fifty years of research showing that one specific kind of practice — reassembling the sentences of great writers — produces writing gains no classroom has ever matched.

In 1973, researcher Frank O'Hare gave seventh graders one semester of exactly this kind of practice. They finished the semester writing like twelfth graders.

Five grade levels of writing proficiency.
One semester.

That's not a fluke. A landmark Carnegie Corporation review of 176 empirical studies ranked sentence combining among the most effective writing interventions ever documented — for students from fourth grade through college.

The gains go deeper than mechanics. Students didn't just write better sentences. They became better storytellers and stronger revisers. And the research found one more thing: gains eroded without continued practice. Which is exactly why we built a daily game.

Fifty years of research.
Finally in your pocket.

The New York Times 2004 "What Corporate America Can't Build: A Sentence"
A two-time Pulitzer Prize–winning correspondent reported that American businesses were spending $3.1 billion a year retraining employees who couldn't write a coherent sentence — one of the largest reader responses in the paper's history.
The Atlantic 2012 "The Writing Revolution"
When one New York City high school rebuilt its entire curriculum around sentence-level writing practice, graduation rates climbed 17 points and state exam pass rates jumped 22 points. Educators called the results extraordinary.

There's a reason Duolingo
has 500 million users.

When learning feels like play — when the challenge is real, the stakes are low, and you can feel yourself getting better — people show up every day.

We applied that principle to the thing that matters most: the sentence.
