Changelog | Page 3

I have done a major update to the Library page. Now, the Library experience is much more unified, allowing you to use the same interface to manage different kinds of resources. Additionally, you can create flashcards, study notes, quizzes, and summaries from the library. You no longer need to generate a concept map first to create this content. Finally, the content section is so much more polished, and you can generate different kinds of study materials from your saved content.

One of the most popular models of late, Kimi K2, is now available on Heuristica!

This is another big update for Heuristica. Now, the chats are automatically saved in your library where you can continue the conversation. You can also initiate conversations from the library. This is a big update and there is going to be a lot of new features around this chat functionality.

Replaced Claude Sonnet 3.7 with Claude Sonnet 4 🎉

You can now use AI when creating custom prompts to give more precision and depth to your prompts.

You have now more control over the generated content when using the sidebar. You can determine the amount of study notes/flashcards, etc. or choose the kind of summary you would like alongside with custom instructions you have.

Previously, you couldn’t generate content like summaries or blog posts from the sidebar for linked content (such as PDF, wikipedia article, or YouTube videos) where the actual content is external to the canvas. However, this is now fixed. You should be able to generate content for these nodes when they are selected.

Updated some of the available models in Heuristica. o3-mini is now replaced by o4-mini, and Claude 3 Haiku has been replaced with Claude 3.5 Haiku. Additionally, replaced Claude Sonnet 3.5 with Sonnet 3.7. Finally, added the Gemini 2.5 Pro model! 🎉

AI feature is now enabled in the text editor for the Subscribing users! You can now run any AI prompt on the highlighted text.

Slowly switching to a new, Notion-like, text editor that is much nicer to use. Additionally, AI features will be added to this editor in the upcoming days to make it even more powerful. Currently, the new text editor is only available inside the Edit Node modal.
