About Sublingo
Most language apps ask you to collect points. Sublingo asks you to read a story — and gives you one short enough to finish, at a level where you understand nearly all of it and have to work for the rest.
Why reading
You learn a word properly when you meet it doing its job in a sentence, not on a card by itself. So the story is the lesson. Tapping a word you do not know is not an interruption of the reading — it is the reading. And because the app knows which words you tapped, it can bring them back on the day you would otherwise have forgotten them.
How the stories are made
The stories are written by AI, and reviewed before they are published. Each one is planned against a vocabulary level, written, illustrated, and read aloud by synthesized voices — then put through automated quality checks and a human read before any learner sees it. Stories that fail are held back rather than shipped, which is why the catalog grows slowly.
We say this on the front page and here because you would notice anyway. What matters is not that a machine wrote it, but whether the sentence in front of you is at your level, means what the translation says it means, and is worth the four minutes.
Who makes it
Sublingo is built by one person. There is no support team, no growth department, and no investor deadline shaping what ships. When you email support@sublingo.co, that is who answers.
Where it is going
English first, because doing one language properly is harder than it looks and doing six badly is easy. The explanations already work in 33 languages. More target languages come after the English catalog is good enough that we would recommend it to someone we like.
