Actionbook | Make your agents act 10x faster with 100x token savings.

Developers whose browser agents keep fumbling modern websites are the people Actionbook is built for.

Actionbook is an AI developer tool that gives agents verified selectors for precise DOM targeting, so they stop guessing which element to click or fill.

The appeal is speed and cost: agents act up to 10x faster and use up to 100x fewer tokens, because they no longer spend model calls working out page structure on every step.

The tricky part of browser automation is usually the page itself.

Single-page apps and virtual DOM setups tend to break traditional methods, and Actionbook is aimed squarely at those cases.

It works with any LLM, framework or browser automation tool, so you can add it to the agent stack you already run instead of rebuilding around it.

That also means some integration work on your side.

Actionbook sits inside an existing agent setup and does not replace it.

If your agents mostly hit static pages, the gains will likely matter less.

For heavy web actions on dynamic sites, it addresses a real pain point.
