I just spent a few hours making these Gemini Notebooks:
Complete Tipitaka including all commentaries, sub commentaries, and others from Open Tipitaka
Complete Tipitaka+commentaries+sub commentaries from Open Tipitaka
Complete Tipitaka + commentaries from Open Tipitaka
Complete Tipitaka from Open Tipitaka
All in Pali English, source from Open Tipitaka. https://dhamma.paauksociety.org/index.php?dir=Root%2FTipitaka%2FTipitaka%20English%20translation%20V5.0%20pdf-epub-txt
The md files was converted from epub using: Google Colab . It’s very good for bulk conversion of a lot of things to md files of the right length for Gemini Notebook, and one can also choose to combine multiple files, it will still limit the length so that Gemini Notebook can read them.
