SkimIt is an AI-powered tool that allows users to quickly get summaries of any article by emailing a link to go@skimit.ai. It also provides drafts of shareable tweets and a LinkedIn post to easily share the summary with friends. The summaries are generated by OpenAI's GPT technology and are not guaranteed to be accurate. The data stored by SkimIt is limited to the email address that sent the request, any CC'd email addresses, and the first URL sent within the email.
