Sumr is a Safari extension (also works on iPad, Mac, and Vision Pro) that lets you summarize any webpage, YouTube video, product page, job posting, or legal document with a single tap. Instead of reading through long articles or watching entire videos, you get a concise summary in seconds. You can choose from over 40 languages for the output, and even ask follow-up questions to dig deeper into the content without leaving the app.

Using Sumr is straightforward: open any page in Safari, tap the Share button, and select Sumr from the menu. The AI instantly generates a summary, which you can then save locally, share with the source link, or revisit later. What makes Sumr stand out is its flexibility with AI providers. You can use Sumr's built-in service for a subscription fee, or bring your own API key from OpenAI, Anthropic, Google Gemini, or any OpenAI-compatible endpoint like OpenRouter or Groq. This gives you control over cost and model choice. Other handy features include custom prompts for tailored summaries, cross-device sync via iCloud, and a strong focus on privacy — no tracking, and all summaries stay on your device unless you share them.

Sumr is ideal for anyone who regularly consumes online content and wants to save time. Students can quickly digest research articles, professionals can review product pages and job postings, and travelers can understand foreign-language web pages. The free trial lets you test it without commitment, and the BYO API key option keeps costs low for heavy users. It's a simple, practical tool that does exactly what it promises — no fluff.
