# Summarize

Fast CLI to summarize URLs, local files, and YouTube links.

## Quick start

```bash
summarize "https://example.com" --model google/gemini-3-flash-preview
summarize "/path/to/file.pdf" --model google/gemini-3-flash-preview
summarize "https://youtu.be/dQw4w9WgXcQ" --youtube auto
```

## Model + keys

Set the API key for your chosen provider:

* OpenAI: `OPENAI_API_KEY`
* Anthropic: `ANTHROPIC_API_KEY`
* xAI: `XAI_API_KEY`
* Google: `GEMINI_API_KEY` (aliases: `GOOGLE_GENERATIVE_AI_API_KEY`, `GOOGLE_API_KEY`)

Default model is `google/gemini-3-flash-preview` if none is set.

## Useful flags

* `--length short|medium|long|xl|xxl|<chars>`
* `--max-output-tokens <count>`
* `--extract-only` (URLs only)
* `--json` (machine readable)
* `--firecrawl auto|off|always` (fallback extraction)
* `--youtube auto` (Apify fallback if `APIFY\_API\_TOKEN` set)

## Config

Optional config file: `~/.summarize/config.json`

```json
{ "model": "openai/gpt-5.2" }
```

Optional services:

* `FIRECRAWL_API_KEY` for blocked sites
* `APIFY_API_TOKEN` for YouTube fallback
