# Ondit > A directory of software products, recorded in the same fields across every product in a category so they can be compared directly. Where a fact has a source, it carries the URL it came from and the day it was captured. On top of that, a weekly measurement of which sources AI answer engines actually cite when asked about these categories. What is original here: the comparison across products, the dated weekly series, and the citation measurements. Individual facts such as a star count or a licence are sourced and linked, not exclusive. Licence: dataset pages are CC-BY-4.0. Attribute as "Ondit" with the page URL. ## Optional - [All products](https://ondit.ai/directory) - [Chinese edition](https://ondit.ai/zh) - [Full text of every dataset page](https://ondit.ai/llms-full.txt)
