TL;DR: Sumr gives you the gist of any web page, PDF, or video in seconds.
Summarize articles, PDFs, YouTube videos, social media videos, and more. Right from Safari, Files, or the Share sheet.
- Share any content to Sumr
- Get a clean summary instantly

Use Cases:
- Long articles you don't have time to read

The Problem:
We have way more content online than we ever will be able to consume. Articles are cluttered, PDFs are dense, videos are long. You need to choose what's worth your time.
The Solution:
Sumr gives you the substance without the filler. One tap from any app, and you know whether an article, PDF, or video is worth your attention - without committing to the whole thing right away. After reading the Sumr, you decide if you want to read/watch the content in full.
Key Features:

The extension gives summaries in an easily digestible way and provides key metrics instead of a blob of text. Good for getting the gist and deciding if I want to read the full thing. Also like that it uses my GPT key for better security and privacy and does not require a subscription. Simple and useful.

I appreciate these quick summaries on both desktop and mobile. A minimal, clean UI that’s highly functional. Cheers!

thank you for your kind words! it truly means a lot.
Why no option for LLM
Blackbery-12
The app doesn’t allow you to use the LLM of your choice. You must use ChatGPT’s API, which is nothing I want.
Developer Response
i am considering adding support for more LLM providersEDIT 1: since v2.20 Sumr supports Anthropic and custom (openAI compatible) providersEDIT 2: since v2.30 Sumr supports Google Gemini
Deep Sumr beta, Exports and backups are here, first-class support for xAI for the BYOK users!
- Deep Sumr beta for videos (subscribers): after a video summary finishes, tap "Deep Sumr" to add visual analysis of what's on screen - demonstrations, text overlays, ingredients, steps - then re-summarize with the full picture. Great for cooking, tutorials, product demos, and any video where the transcript isn't available or enough.
- Summaries now render markdown in the output: bold, italics, headers, and clickable links.
- Markdown export: save summaries as .md files with title, date, type, and URL in the frontmatter. Export a single entry, multiple entries, or everything at once.
- Backup your full summary history (original input, summary, follow-up Q&A) as a .sumrbackup file, and restore it incrementally on any device with duplicate detection. Great for moving between phones even if they are not on the same iCloud account or keeping a local archive.
- New provider: bring your own xAI API key and pick from Grok models alongside OpenAI, Anthropic, Google, and Custom.
- Also new for providers: tap "Check API Key" in xAI settings to verify your key in one go.
- Bulk actions: swipe left on any summary to enter selection mode - delete or export multiple summaries at once. Search and filters stay active while selecting.
- Force Sync across devices when iCloud gets stuck, plus visible iCloud account status to help troubleshoot cross-device sync.
