## Why Actionbook?

### <Icon icon="xmark" color="#ef4444" /> Without Actionbook

Building reliable browser agents is difficult and expensive:

* **Slow Execution:** Agents waste time parsing full HTML pages to find elements
* **High Token Costs:** Sending entire DOM trees to LLMs consumes massive context windows
* **Brittle Selectors:** Updates to website UIs break hardcoded selectors and agent logic immediately
* **Hallucinations:** LLMs often guess incorrect actions when faced with complex, unstructured DOMs

### <Icon icon="check" color="#22c55e" /> With Actionbook

Actionbook places up-to-date action manuals with the relevant DOM selectors directly into your LLM's context:

* **10x Faster:** Agents access pre-computed "Action manuals" to know exactly what to do without exploring
* **100x Token Savings:** Instead of whole HTML page, agents receive only related DOM elements in concise, semantic JSON definitions
* **Resilient Automation:** Action manuals are maintained and versioned. If a site changes, the manual is updated, not your agent
* **Universal Compatibility:** Works with any LLM (OpenAI, Anthropic, Gemini) and any AI operator framework

## How It Works

<Steps>
  <Step title="Search for Actions" icon="magnifying-glass">
    Find available actions for any website using the CLI (`actionbook search
            "airbnb login"`).
  </Step>

  <Step title="Get Action Details" icon="book">
    Retrieve the full action manual with precise selectors and step-by-step
    instructions (`actionbook get "google.com:/:default"`).
  </Step>

  <Step title="Launch & Execute" icon="bullseye">
    Start a browser session and let your agent execute actions with confidence —
    no guessing, no hallucinations (`actionbook browser start --set-session-id s1`,
    then `actionbook browser goto "https://www.google.com" --session s1 --tab t1`).
  </Step>
