In addition to summarizing, Sumr offers features such as storage of summaries on the user's device for easy access and the ability to translate summaries into different languages. Users retain control over which websites are accessed, and summaries can be shared easily along with source URLs. With no subscription fees and cost-effective use of personal OpenAI keys, Sumr presents a practical solution for those looking to enhance their browsing efficiency.
