"Sumr is an advanced AI tool that delivers concise summaries of web content directly within the Safari browser. Designed to streamline information consumption, it leverages an OpenAI API key to condense lengthy articles, product pages, job listings, and company profiles, helping users quickly grasp key insights without reading through entire pages. This tool proves especially valuable for skimming poorly structured or excessively long articles. Sumr operates with a one-tap summarization feature, ensuring minimal user effort while also enabling easy summary sharing. The generated summaries are stored locally on the device, eliminating the need for repeated summarization and reducing API usage costs. Users can customize language preferences, choosing to translate summaries or retain them in their original language. Additionally, Sumr offers fine-grained control over its access, summarizing web pages only when prompted by the user. Summaries can also be deleted from the device to maintain privacy. The tool includes options for switching between different GPT models to enhance the summarization process. While Sumr is optimized for iOS, iPadOS, and macOS, efforts are underway to extend its compatibility to VisionOS. One of Sumr's standout features is its cost-effective model, as users utilize their own OpenAI keys, eliminating subscription fees. Upcoming developments will introduce advanced features like follow-up queries, customizable prompts, model selection, and on-device summarization for even more control and personalization. "
