There are a lot of study tools out there. If you're wondering how DeDuckt fits into the picture — or whether it's worth switching — here's an honest breakdown.
Most study tools are built around generic content or specific study activities. DeDuckt is built around your uploaded material and lets you choose among several lesson formats.
That's a different category — not a replacement for every tool, but the right one for a specific problem.

Use DeDuckt when you have your own material and want to try a visual explanation, narrated lesson, structured notes, or practice activities. Choose based on the chapter and your study goal, then check important details against the source.
It works best for students who are studying from their own course content rather than a standard curriculum.
Anki is widely used for memorising discrete facts. If you already understand the material and need repeated review, its scheduling system is one option worth considering. The catch: you have to build the decks yourself, or find good ones, which takes time.
ChatGPT is great as an on-demand tutor. If you're stuck on a concept, need something re-explained a different way, or want to generate practice questions from a topic, it handles that well. What it doesn't do is give you a structured lesson from your own PDF, or adapt its output to how you personally learn.
Khan Academy is excellent if your course follows a standard curriculum — especially maths, physics, and chemistry. The video walkthroughs are high quality and the exercises are well-designed. If your exam maps to their content, it's one of the best free resources available. If your course is niche, or your lecturer has their own notes, Khan Academy won't help.
No tool does everything. The students who learn best usually use a combination: DeDuckt to process their own material into lessons, Anki to memorise the key facts, and ChatGPT when they get stuck.
If you've been trying to learn from raw PDFs and highlighting-then-forgetting, DeDuckt is built specifically to fix that.
