> ## Agent Instructions
> H Platform has four products: the Agents API (managed computer-use agents, base URL https://agp.eu.hcompany.ai/api/v2 or https://agp.hcompany.ai/api/v2 for the US), the Models API (OpenAI-compatible Holo vision-language models at https://api.hcompany.ai/v1), HoloDesktop CLI (Holo on the user's own desktop), and HoloTab (a free no-code Chrome extension that runs Holo in the user's browser, with recordable routines and schedules).
> Authenticate with a bearer API key from the HAI_API_KEY environment variable. SDKs: `pip install hai-agents` (Python, `from hai_agents import Client`) and `npm install hai-agents` (TypeScript, `import { HaiAgentsClient } from "hai-agents"`). CLI: `hai`.
> Agents do work in a browser or on a desktop; describe the task as an imperative instruction. To run a task quickly, prefer the pre-built agent `h/web-surfer-flash`. Read results from the session's `latest_answer` after it reaches a terminal status.
> Sessions are the unit of work; wait for a terminal status (completed, failed, timed_out, interrupted) before reading the answer. Use webhooks or the `changes` long-poll endpoint to follow progress.

# HoloTab

> HoloTab is a free Chrome extension that runs Holo in your browser. Describe a task in the side panel, watch it navigate and act, then record routines and put them on a schedule.

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](https://chromewebstore.google.com/detail/holotab/hlaoiikljjgcjdhkakedfngifaopbcop), then follow the [quickstart](/holotab/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](/holotab/routines-and-schedules) and [schedule](/holotab/routines-and-schedules#schedules) it. Before you start, read [Autonomy and safety](/holotab/autonomy-and-safety).

## FAQ

<AccordionGroup>
  <Accordion title="Is HoloTab free?">
    Yes. Install it from the [Chrome Web Store](https://chromewebstore.google.com/detail/holotab/hlaoiikljjgcjdhkakedfngifaopbcop) and sign in. HoloTab is a public research preview.
  </Accordion>

  <Accordion title="How is HoloTab different from AI browsers like Comet, or from OpenClaw?">
    HoloTab is an extension inside the Chrome you already use. Comet is a separate Chromium browser, and OpenClaw is a self-hosted assistant stack. HoloTab focuses on getting tasks done and repeating them: it clicks, types, and navigates, then records routines and schedules them. It needs no site APIs and nothing to host.
  </Accordion>

  <Accordion title="Can I use the model behind HoloTab in my own product?">
    Yes. HoloTab runs on Holo4. The same model is available through the [Models API](/models-api/introduction), and the open-weight sizes run locally with [HoloDesktop CLI](/holo-desktop-cli/introduction).
