Frequently Asked Questions

Specific queries about how our AI handles your educational content.

How does the AI create the map from my chemistry notes?

The AI analyzes the semantic structure, topic hierarchies, and relationships between chemical terms in your uploaded text to algorithmically build the nodes and branches of the mind map.

What file types can I upload to generate the Substances and Changes map?

You can upload common educational files including PDFs, DOCX, PPTX, and plain TXT files. The AI reads the text content within these formats.

Is this better than using a standard mind map template for chemistry?

Yes. A template is static. Our AI generator creates a unique, personalized map based *exactly* on the content and depth of your specific notes, ensuring maximum relevance for revision.

Is the AI mind map generator available for a free trial?

Yes, CogniGuide offers a free tier that allows you to test the AI generation capabilities on smaller documents to experience the speed and accuracy firsthand.
