Changelog

There is now a free PDF Summarizer and a free YouTube Video Summarizer tool as part of our Free AI Tool Collection.

You can now filter Concept Maps in your library based on labels to organize your saved maps better.

Using Extract to extract keywords from nodes now returns the keywords with their short definitions.

Previously, Heuristica nodes were designed as being immutable. AI would generate their content, but the generated content could not be edited. The idea behind this design was to ensure the concept maps made sense to anyone looking at them. If you are to update the content of a node without updating the downstream nodes, then it can create misleading or confusing maps. However, the edit functionality has been requested a lot for a long time so it is now enabled for most nodes. You can launch the edit menu by double-clicking a node or from their context menu.

You can now create study notes from concept maps or selected nodes. These study notes can be saved to the library for further editing or published to be shared with others who don’t have a Heuristica account.

You can now create lesson plans from your concept maps. You can also configure the length of the lesson as well as the grade level and the target outcomes.

One of the latest models from Google, Gemini 2.0 Flash, is now available on Heuristica!

Added support for the latest OpenAI model, o3-mini. o3-mini is a model that is optimized for STEM reasoning. You can read more about it here: https://openai.com/index/openai-o3-mini/

Added support for DeepSeek-V3 and DeepSeek-R1. I especially like the R1 model since it shows the chain of thought reasoning of the model, which is sometimes even more informative than the answer it provides. Currently, R1 is in Beta, and I am evaluating the long-term viability of providing this model.

Added support for the Google Gemini Pro and Google Gemini Flash models. Google Gemini Flash is very fast and useful when generating long content like Flashcards or Quizzes.
