See What Others are Saying

LSBot has been extremely helpful in getting me unstuck multiple times. In this environment of remote studying, I wouldn't have been able to get this far without it. Kudos to Launch School for creating such a valuable study tool.

When I ask conceptual questions, I like that LSBot provides the course and assignment where I can read more about the concept. This way I understand better the scope of the content, and avoid rabbit holes.

Whenever I was confused on subject, stopping and getting clarifying answers helped me retain more information about what I was reading. Changing code slightly and asking LSBot why the output changed/stayed the same was very helpful, even if it was just to confirm my thoughts on it.

I used LSBot to further explain some terminology that wasn't entirely clear from the course text alone. LSBot's responses set me on the right track immediately. LSBot's code reviews were also incredibly thorough and pushed me to make even the smallest improvements to my programs to achieve a professional polish.

I really enjoyed the questions LSBot asked throughout the course as they kept me engaged with the material on a deeper level and made sure I wasn’t just skimming along on a surface understanding. I liked how LSBot tied concepts together and pushed me to think critically through its more challenging questions.

LSBot is so helpful compared to other LLM services. Other paid services do allow for robust inference but the way LSBot and I are able to reference the same body of knowledge in the curriculum just feels so natural that I can't find a compelling reason to NOT use it.

I used LSBot quite a bit during this course. I found the ability to ask clarifying questions directly on the pages of lessons and exercises was very helpful.

LSBot asking questions about the course material as you work through it has been absolutely instrumental in the learning process. It encourages critical thinking in real time and ensures that you stay fully focused on the material instead of passively reading through it.

LSBot has been amazing in helping me get unstuck…Brilliant. During code reviews it pointed out quite clearly the areas I needed to work on which is exactly what I needed. Really liked the LSBot review questions peppered in text books and long text blocks.

I use LSBot to check my logic at each step. I first share my algorithm, and once that’s clear, I share my code. I also check with LSBot for every sub-process, not just at the end of writing the entire program.

I was able to work through problems I was stuck on thanks to LSBot's support. I especially appreciated that it could guide me even when my approach differed from the suggested solution, giving me access to at least two ways to solve each problem.

I made great use of the in-lesson questions. I found the questions themselves really good because they're thought-provoking, and really help you figure out if you're getting the material as you're going through it.
