Supported Upload File Types

Last updated May 17, 2026

Kryptonote supports a variety of common file types to be turned into sources for the AI. The maximum file size per document is 5mb, and you can upload 10 of them per notebook.

Pure Text

Kryptonote supports plaintext formats such as .txt text files, .md markdown files.

Web Content

Kryptonote also supports html content from .html files.
Currently we do not support uploading URLs to websites, though we are looking into it. As a current workaround, you may navigate to the website yourself, and press ctrl+s (command + s on mac), and then upload the generated html file as a source.

Microsoft Office

You can upload Microsoft Word (.docx), PowerPoint (.pptx), and Excel (.xlsx) documents. When Kryptonote parses them, images will be removed for now, though we are looking for ways to extract text/content from them
