Can Ailurn use my PDFs like Mentorbook?

On Pro you can attach up to three files while planning a course; Plus removes the file cap. Ailurn still generates a full course from a description if you have no files. Mentorbook is built around a corpus from the first step.

Which is better for YouTube-based learning?

Mentorbook is explicitly set up to turn videos and articles into a path. Ailurn is better when the YouTube video is one input among a goal, not the entire curriculum.

Do I need source material to use Ailurn?

No. Describe the outcome, level, and time budget. Attach files only if you want the plan grounded in your notes or a brief.

Is Mentorbook a competitor to Ailurn?

Yes for self-directed AI learning, with a different default: sources in vs. goal in. Many people will want both patterns at different times.

The difference

Ailurn vs Mentorbook in practice

Mentorbook’s differentiator is ingestion. You bring PDFs, articles, or videos; the AI mentor chunks them into a path and talks you through the material. That is ideal when the curriculum already exists and you need a guide.

Ailurn starts from an outcome (“enough SQL for reporting, 30 minutes a day”). Planning chat can use web research and, on Pro/Plus, attached files—but you do not need a textbook to get a full outline and lessons. The lesson workspace then adds Ask, audio, quizzes, flashcards, and slides.

If your bottleneck is “I have 40 pages of notes,” Mentorbook or NotebookLM may feel more native. If your bottleneck is “I don’t know what to learn in what order,” Ailurn is the closer fit.

Mentorbook is a strong fit when

Learning from materials you already have
YouTube or article-based study
Conversational mentoring through a corpus

Mentorbook is a mentor over your materials. Ailurn is a course generator and study workspace that can optionally use your files.
