Instantly Extract Key Points from Any URL or Local File

Ever find yourself staring at a long article, research paper, or documentation page, wishing you could just get the gist without the time sink? We've all been there. The context-switching cost of reading something lengthy can derail a coding session. What if you could get a clean, concise summary in seconds?

Enter summarize—a clever open-source tool that does exactly that. It's a local, privacy-focused utility that uses machine learning to extract the key points from any URL or local text file, right from your terminal.

What It Does

In a nutshell, summarize is a command-line tool built in Swift. You feed it a URL or a file path, and it fetches the content, strips away the noise (like navigation and ads), and runs the core text through a local on-device summarization model. It then prints a well-structured summary to your console. No API keys, no data sent to the cloud—just your text and your machine.

Why It's Cool

The magic here is in the implementation and the philosophy. First, it's entirely local. It uses Apple's Core ML framework, meaning your data never leaves your computer. This is huge for privacy and for working with sensitive or proprietary documents.

Second, it's surprisingly effective. It's not just doing simple extraction; it's using a Transformer-based model (specifically a distilled version of BART) trained for summarization. This allows it to generate abstractive summaries—paraphrasing and condensing ideas—not just picking out random sentences.

Finally, it's incredibly developer-friendly. It's a single binary. The workflow is seamless: you're reading a GitHub issue, a long blog post, or a local README.md, and a quick command later, you have the TL;DR. It fits perfectly into a developer's existing flow without needing a browser extension or a separate app.

How to Try It

Getting started is straightforward if you're on a Mac (it requires macOS and Swift to build).

1. Clone the repo:

   git clone https://github.com/steipete/summarize.git
   cd summarize
   

2. Build it:

   swift build -c release
   

3. Run it: The binary will be in .build/release/. You can move it to your /usr/local/bin for easy access, or run it directly.

   .build/release/summarize https://example.com/some-long-article
   

   For a local file:

   .build/release/summarize path/to/your/file.txt
   

There's no official hosted demo because the whole point is running it locally, but the GitHub repo has all the details you need.

Final Thoughts

As developers, we're constantly consuming information. summarize feels like a pragmatic tool that respects your time and your privacy. It's the kind of utility you might not think you need until you've used it a few times, and then it becomes a quiet part of your toolkit. It's especially useful for quickly parsing through lengthy error logs, meeting notes, or that one RFC you've been putting off reading. It's not perfect—no summarization tool is—but for a local, zero-config tool, it's impressively capable.
