PDF Performance Updates
Fixed several performance issues on the PDF pages. As a result, large PDFs should load much faster (10x increase) and the whole experience should be much smoother.

When using LLMs, context is everything. It is a known fact that a large context deteriorates the LLM performance, and that’s why you probably never want to upload a huge PDF and ask it to summarize it for you. You will likely not get an accurate or even a decent answer. You can now use the range controls in Heuristica to restrict the context to the parts that you care about, so you can get better answers for your questions.
You can now create study materials from the selected text instead of using the whole document.
Previously, you could only create content from the entirety of a resource. This is not a problem, but sometimes you might want to focus on certain parts of a video, a PDF, or a podcast. You can now do so by using the range controls to generate study materials from the parts that you care about the most.t
You can now chat with your Flashcards, Study Notes, and Quiz Questions to clarify questions and enhance your learning experience.
The chat sidebar is now updated for you to create study materials as well as load previously created ones. With the new chat sidebar, all the content you need for a better learning experience is in the same view. The new sidebar is currently available for videos, PDFs, podcasts, and content pages. It will be made available for other pages as well.
Flashcards are now updated to support markdown text, colors, changing review order, editing in review mode, additional publish options. You can also now save published flashcards to your own decks.
Another resource type is now available Heuristica. You can now search for podcast episodes, chat with transcripts, and generate study materials like flashcards, or quizzes from them.
You can now use labels to organize your content for all resource types (like Flashcards, Quizzes, Chats and more). The labels are inherited. So when you have a YouTube video with a label called “Technology”, the flashcards or quizzes generated from that video will also have that label as well.
You can now chat with saved YouTube videos via the YouTube video page.
