Turn a textbook page into an interactive exercise

Your textbook, now checked automatically

Most teachers already have the material they need: a coursebook, worksheets, their own PDFs. What takes time is turning it into something students can do online and that checks itself. Letros does that step for you.

A recognised exercise opens in the editor before it is saved, so nothing reaches students without your review. Change a gap, add a distractor, fix an answer and save.

Eleven exercise types from a photo

Letros chooses the type that fits the page:

• Fill in the blank
• Word choice
• Drag and drop
• Matching
• True or false
• Quiz
• Sort into columns
• Word order
• Vocabulary
• Writing reviewed by the teacher
• Article or reading text

Or describe what you need and let AI build it

Write a prompt, attach images, a PDF or a Word file, and AI builds several exercises at once, in the language of your course. Each one opens in the editor for review. A full lesson from your PDF takes about a minute.

Checked on the server, three attempts per item

Students get three attempts per item and see right away what is correct. The answers are checked on the server and never sent to the student's browser, so they cannot be looked up. You see each student's results and every wrong attempt.
