HoloTab is a free Chrome extension that runs Holo4 in a side panel. It looks at the active tab, picks the next click or keystroke, and does it. It needs no API integrations, setup, or code. Add HoloTab to Chrome, then follow the quickstart to run a first task.
Typical uses: triage an inbox and draft replies, book a restaurant and add it to your calendar, compare flights and hotels, draft resale listings on eBay or Vinted. Record a task once as a routine and schedule it. Before you start, read Autonomy and safety.
