Supported Upload File Types

Last updated July 4, 2026

Kryptonote supports a variety of common file types and web pages as sources for the AI. Your current plan controls the maximum file size, storage allowance, and number of sources you can add to a notebook.

Pure Text

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

Web Content

Kryptonote supports adding web pages directly by URL. Paste a URL when creating a notebook or from the Sources screen, and Kryptonote will fetch the page, convert the readable content into a source, and keep the original page URL attached for reference.

You can also upload saved web pages, such as .html files, when you already have a local copy.

Microsoft Office

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