Letros

Make interactive exercises with AI in seconds

Write what you need in plain words: "fill-in-the-gap on Past Simple, A2, ten sentences". Attach a page, a PDF or a Word file if you like. AI builds the exercises with answers already filled in, and each one opens in the editor so you can check it before saving.

From a request to ready exercises

Ask for one exercise or several at once. Mention the level, the grammar point, the topic or the words to practise, and add up to five files as material. AI picks a suitable type for each task; you can ask for a specific type instead.

12 exercise types

Everything AI builds is a normal Letros exercise: students do it online and get instant feedback.

  • Fill in the gaps, word choice, drag and drop
  • Matching, true or false, multiple choice
  • Sort into columns, word order
  • Vocabulary with pictures and audio, articles
  • Writing tasks checked by AI

No credits to buy

Many tools count AI generations and sell top-ups. Letros doesn't: every plan, the free one too, includes up to 30 AI requests per teacher a day, and one request can build up to 5 exercises.

You stay in control

AI drafts, you decide. Every exercise opens in the editor before it is saved, so you can fix a sentence, swap a word or drop a question. Nothing reaches your students without your review.

Questions and answers

Is there a limit on how many exercises I can make?

Every plan, the free one too, includes up to 30 AI requests per teacher a day. One request builds up to 5 exercises, a document import up to 100. There are no credits to buy.

Can it build exercises from my textbook?

Yes. Attach a photo of the page, a PDF or a Word file and say what you need. To copy an existing exercise from a page as it is, see Exercises from PDF and photos.

Which languages does it work with?

Are the answers always right?

Usually, but AI can make mistakes. That's why every exercise opens in the editor for your check before students see it.
