summarizer | Summarize a link or text using LLM

summarizer is a command-line tool that uses large language models (LLMs) to summarize text or any content from a URL. It currently supports Anthropic (Claude), OpenAI (GPT), Google (Gemini), and local Ollama models.

Source code is available on GitHub.

Setup​

To install realpacific/summarizer,

uv tool install git+https://github.com/realpacific/summarizer

After installation, you need to run a one-time setup to configure with your preferred LLM provider.

summarizer init
#? Choose a provider: Anthropic (Claude)
#? Choose a model: claude-haiku-4-5
#? Enter your Anthropic (Claude) API key: ***********************************

You can also configure it to use your locally running models. Make sure you have Ollama running and serving your desired model, then point the summarizer to it during initialization.

ollama serve
ollama list
# NAME               SIZE      MODIFIED     
# gemma3:latest      3.3 GB    35 hours ago  
summarizer init
#? Choose a provider: Ollama (local)
#? Choose a model: gemma3           <-------- choose your model
#? Base URL: http://localhost:11434 <------- point to your local Ollama server

Usage Instructions​

Summarize an article from a URL

summarizer https://prashantbarahi.com.np/blog/your-readme-md-is-obsolete

Summarize a text

summarizer "some text to summarize"

Pipe your file or your clipboard to it. This is best for dynamic pages or contents behind paywalls.

cat file.txt | summarizer
pbpaste | summarizer

Is the article you're trying to summarize too complex? You can override the model for current run using:

summarizer --model claude-opus-4-8 https://prashantbarahi.com.np/blog/your-readme-md-is-obsolete

Is the content behind a paywall or is it loaded dynamically and the summarizer is not able to extract it? Copy the content to your clipboard and pipe it to the summarizer:

pbpaste | summarizer

Still confused? You can ask follow-up questions too. Just add the --ask flag:

summarizer https://prashantbarahi.com.np/blog/your-readme-md-is-obsolete --ask

My personal favorite use case: Pipe the summary to realpacific/readthis. It is a CLI-based Text-to-Speech tool, and you can turn any summary into audio with:
