Download Sumr – AI Text Summarizer for Safari

Download Sumr – AI Text Summarizer for Safari Users

Sumr is an AI‑driven text summarizer built specifically for the Safari browser. By harnessing the power of the OpenAI API, Sumr instantly condenses long‑form articles, product pages, job postings, and virtually any web content into concise, easy‑to‑read summaries. The tool works with a single click, eliminating the need to copy‑paste text into separate applications or open additional windows. In addition to summarization, Sumr stores every summary locally, offers multilingual translation, and lets you share results together with the original URL. Because it runs on your own OpenAI key, there are no hidden subscription fees—just the cost of the API usage you choose. For anyone who spends a lot of time reading online—students, researchers, marketers, or casual browsers—Sumr provides a faster, more efficient way to capture the essence of the web without sacrificing depth or accuracy.

Installation & Usage Instructions

Step‑by‑Step Installation

1. Open the Sumr page on the Mac App Store.
2. Click Get and then Install. The extension will be added to Safari automatically.
3. After installation, launch Safari and go to Preferences > Extensions. Ensure the toggle for “Sumr – AI Summarizer” is turned on.
4. When prompted, paste your OpenAI API key. If you don’t have one, you can generate it from the OpenAI dashboard.

How to Use Sumr Effectively

Once Sumr is active, using it is as simple as it gets:

• Navigate to any article, product description, or job posting you want to condense.
• Click the Sumr icon located in Safari’s toolbar (it looks like a folded paper with a lightning bolt).
• A sidebar slides in, showing a brief summary. You can adjust the length of the summary by dragging a slider from “Brief” to “Detailed”.
• If you need the summary in another language, select the language from the dropdown menu at the bottom of the sidebar. The translation happens instantly.
• To save the summary, hit the Save button. All saved items appear under the “My Summaries” tab, where you can search, rename, or delete entries.
• Sharing is equally straightforward—click the Share icon, choose your preferred platform, and the summary will be sent together with the original URL.

Because Sumr runs locally, you never need to copy text into external services, and your data stays on your device unless you choose to share it. The combination of speed, simplicity, and privacy makes Sumr a must‑have tool for anyone looking to get more done while browsing.

Frequently Asked Questions (FAQ)

Do I need an internet connection for Sumr to work?

Yes. Sumr relies on the OpenAI API, which requires an active internet connection to send the text and receive the summarized output.

Is my data stored on OpenAI’s servers?

Only the text you send for summarization is temporarily processed by OpenAI’s servers. Sumr does not retain any of that data after the summary is returned, and all summaries are stored locally on your device.

Can I use Sumr on a Windows PC?

At present, Sumr is an extension for Safari on macOS. Windows users can still access the core summarization engine via the web portal, but the seamless one‑click experience is Safari‑only.

How much does the OpenAI API cost me?

OpenAI charges per token processed. The exact cost depends on the model you select (e.g., GPT‑3.5 vs. GPT‑4) and the length of the source text. You can monitor usage in your OpenAI dashboard to keep expenses under control.

Is Sumr compatible with Safari’s Reader mode?

Yes. When Reader mode is active, Sumr can still access the underlying HTML content and generate a summary, providing an extra layer of convenience for distraction‑free reading.
