Original Summary

I&#x27;ve always been a lifelong learner and have always tried to get through digital textbooks. Anyone who&#x27;s used pdf textbooks know how much of a love&#x2F;hate relationship it is.<p>There are so many foundational textbooks published online for free now such as OSTEP, Modern Robotics, and Applied Linear Algebra just to name a few.<p>- <a href="https:&#x2F;&#x2F;pages.cs.wisc.edu&#x2F;~remzi&#x2F;OSTEP&#x2F;" rel="nofollow">https:&#x2F;&#x2F;pages.cs.wisc.edu&#x2F;~remzi&#x2F;OSTEP&#x2F;</a> - <a href="https:&#x2F;&#x2F;hades.mech.northwestern.edu&#x2F;index.php&#x2F;Modern_Robotics" rel="nofollow">https:&#x2F;&#x2F;hades.mech.northwestern.edu&#x2F;index.php&#x2F;Modern_Robotic...</a> - <a href="https:&#x2F;&#x2F;web.stanford.edu&#x2F;~boyd&#x2F;vmls&#x2F;" rel="nofollow">https:&#x2F;&#x2F;web.stanford.edu&#x2F;~boyd&#x2F;vmls&#x2F;</a><p>I&#x27;ve always preferred reading textbooks physically and writing inside them, but now with LLMs, it&#x27;s nice to be able to just paste in passages to ChatGPT and ask for clarification.<p>I&#x27;ve tried so many different types of digital note taking like Notability, Goodnotes, Margin Note, etc but none of them really made it easy for me to dive into dense material. I find myself getting distracted trying to take notes and forgetting what I just read.<p>Out of my frustration, I decided to create my own tool and have been using it to get through my own personal studies. I built it around these core principles.<p>- Technical textbooks are dense. I need to be able to quickly jot down a thought without distracting myself - I need to be able to pick up from where I left off quickly when I have quick bursts of inspiration to study - I need to be able to take scattered notes, and synthesize them into a cohesive subtopics so I can build on top of this knowledge as I progress in the textbook - Using the textbook needs to be fluid. It must be a good PDF reader first and foremost.<p>I can safely say that what I&#x27;ve built is by far my favorite way to study any deep material. I&#x27;m able to take things line by line to truly understand how the author has built up their reasoning.<p>This might be a biased view but firmly believe this tool could help anyone who have always tried learning new material.<p>There are so many good free resources out there now, especially in AI, Math, Robotics. It&#x27;s never been a better time to learn and I hope Margin helps anyone who&#x27;s attempted to get through dense material as much as it has helped me.
