dEssence is a personal AI assistant that helps users organize information they send to it and follow up on related tasks. Users can submit links, screenshots, emails, files, products, places, dates, and ideas. The assistant interprets each submission, identifies relevant details, and creates a summary that can be saved for later use. The service can monitor saved items for changes such as price drops, availability, deadlines, and other updates. It may notify users when something changes or requires attention, with examples including a product reaching a target price, an upcoming subscription renewal, or an available reservation. The workflow is to send an item, have the assistant interpret and organize it, and receive a follow-up when relevant. The website lists support for Spanish (Latin America) and Portuguese (Brazil). It does not specify device, operating system, or other technical requirements in the provided information.
