Course from a topic
Describe any subject with no source file and Lernoa builds a full course from scratch.
Whole learning path
Describe a subject once and Lernoa plans a series of focused courses, one per topic, then builds them for you.
Free tailoring wizard
Up to three quick questions about your goal, experience, and learning style shape the course before it is written, at no credit cost.
Choose the shape
Set the level, chapter count (auto or manual), and content depth (standard or extended), and toggle whether to include quizzes and a final exam.
Generate in nearly 30 languages
Build a course or deck in any of nearly thirty languages, from English and Spanish to Japanese, Arabic, and Hindi.
Durable background builds
Long learning-path builds run server-side with live progress, retry, and resume after you close the tab.
Import and export courses
Import courses from Markdown or text files, up to fifty at once, and export any course or a whole subject back to Markdown, free.
02
Study courses that actually explain
Read each chapter with summaries, analogies, and examples, then prove it with quizzes and a final exam.
Chapter reader
Move through a course chapter by chapter with a contents drawer, a progress ring, and mark-complete-and-next.
In-a-nutshell and analogies
Every chapter opens with a nutshell summary and weaves in analogies, examples, and key, tip, and warning callouts.

Single-choice and multi-select questions are graded server-side with explanations, a score, and retakes.
Final exam
A course-level exam with a pass or fail result, launched from the contents or after the last chapter.

Flashcard listen mode

Select any passage in a course and turn it into a manual flashcard: the passage prefills the back, you write the question on the front, saved free to a new or existing deck.
Review before you keep
A review drawer shows the just-generated cards, flags likely duplicates, and lets you delete the weak ones before you save.
08
A spaced-repetition engine that adapts
Review with a proven scheduler that brings cards back at the right moment and retires what you have mastered.
Rate and reveal
Tap to reveal, then rate Again, Hard, Good, or Easy by button, keyboard, or swipe, with next-interval previews.
SM-2 scheduling
An Anki-style SM-2 scheduler moves cards through learning, review, and relearning, with short in-session learning steps.
Adaptive retirement
Cards you reliably recall at a long interval retire automatically, so mastered material stops crowding daily reviews.
Review ahead and cram
When you are all caught up, cram the whole deck ignoring due dates.
Study-style presets
Pick Relaxed, Standard, Intense, or Cram, or hand-tune new cards per day, review caps, steps, ease, and intervals.
