It is currently uncertain what the precise function of Notability is or what category of AI tool it belongs to. However, the available information suggests that it may pertain to note-taking and organization, as it offers the feature to sort notes received through Telegram. Additionally, the page title references an IDE for AWS, which could imply that Notability is tailored for developers working with the AWS platform. Nonetheless, this assertion remains unverified in the text. No specific AI capabilities or technologies used by Notability are mentioned, making it challenging to offer a complete and precise description of Notability as an AI tool.
