System and method for directed analysis of content using artifical intelligence for storage and recall

Methods for directed analysis of content for storage and recall are performed by systems and apparatuses. The methods optimize search operations for content using a user-driven knowledge bank. A user selects content that is relevant or important to the user for addition to the knowledge bank, and content information about the content is determined based on user importance and context, and is also stored in the knowledge bank. Subsequent searches for the content by the user are optimized based on the content information improving accuracy of search results for the content based on more general queries and searches by the user, including natural language queries and searches. Searches and queries are performed via search engines, as well as digital assistants and search applications of user systems. The content can be added by a user from different applications, and recall of the content from different applications is performed using an API.
