Rizemail is an AI-powered email summarization tool that helps users get to the core of their unread newsletters, long email threads, and cluttered commercial communications. Users can simply forward their emails to Rizemail, and the tool will provide a brief summary of the email content. It aims to save users time by summarizing emails directly within their inbox. Rizemail is free to use, with an ad-supported model, and offers a secure and fast way to receive email summaries. A premium, ad-free version with additional features is also planned for the future.
