Summarize extracts clean text and produces summaries from web pages, files, YouTube videos, podcasts, and other audio or video. Use it from the Node.js CLI or from the Chrome Side Panel and Firefox Sidebar.
$ summarize "https://example.com" --extract --plain
This domain is for use in documentation examples without needing permission. Avoid use in operations.
[Learn more](https://iana.org/domains/example)Run it once without installing:
npx -y @steipete/summarize --versionOr install the CLI with npm or Homebrew:
npm install --global @steipete/summarizebrew install summarizeThe npm package requires Node.js 24 or newer. Homebrew/core and the macOS archives on GitHub Releases provide standalone builds. See the installation guide for optional media tools and platform notes.
Extract readable content without an API key:
summarize "https://example.com" --extract --plainFor a model-generated summary, configure a supported provider or use an authenticated coding CLI:
summarize "https://example.com" --cli codexThe default auto model chooses among configured providers. The five-minute quickstart covers API keys, local models, files, YouTube, podcasts, and JSON output.
| Input | Processing path |
|---|---|
| Web pages | Readability extraction, with optional Markdown and Firecrawl fallbacks |
| PDFs, images, and text files | File-aware extraction and model attachments where supported |
| YouTube and podcasts | Published transcripts first, then configured transcription fallbacks |
| Audio and video | Local or cloud transcription, with optional speaker labels |
| Video slides | Scene-based frames, optional OCR, and timestamped output |
Use --extract when you only need clean content, --json for a stable automation envelope, and --slides for video frames. The command reference documents every flag.
Install Summarize Side Panel from the Chrome Web Store to summarize the active tab, chat with its content, and work with video transcripts and slides.
Direct mode runs without a companion service. Browser media uses Chrome capabilities for local transcription and slide extraction; the optional daemon adds CLI model backends, native media tools, OCR, shared caches, and Firefox media support.
To pair the installed CLI, copy the token shown by the extension and run:
summarize daemon install --token <TOKEN>See the extension setup and architecture and troubleshooting guide.
Summarize prefers existing captions and podcast transcripts before it transcribes media. Native ffmpeg, yt-dlp, and tesseract extend codec, YouTube slide, and OCR support; a bundled WebAssembly FFmpeg path covers common media without a native install.
The focused guides describe YouTube extraction, media routing, slides, and local ONNX transcription.
Model IDs use provider/model names. Summarize works with configured API providers, OpenAI-compatible endpoints, Ollama, OpenRouter free models, and authenticated coding CLIs such as Codex, Claude, Gemini, OpenClaw, and GitHub Copilot.
Configuration lives at ~/.summarize/config.json; command-line flags take precedence. Inspect the effective setup without exposing keys:
summarize statusRead the model guide, automatic selection rules, CLI provider guide, and configuration reference for the full setup.
For programmatic extraction without the CLI dependency surface, install @steipete/summarize-core:
npm install @steipete/summarize-coreThe package exports focused content and prompt entry points. See the core package README for usage.
