# Web app

> Chat with Henry in a browser, attach images, and find every setting.

The web app at [app.usehenry.ai](https://app.usehenry.ai) is where Henry's settings and controls live. It also has a full chat.

## Chat

Open **Chat** to start a conversation. Threads are saved and searchable in the sidebar. What you tell Henry here is known when you talk to it in Slack, Teams, or by text.

* **Mode.** The pill in the composer switches between **Quick** (fast answers for lookups and simple tasks) and **Standard** (balanced thinking and tool use, recommended for most work).
* **Images.** Attach up to 10 images per message, 4 MB each, 20 MB total. PNG, JPEG, WebP, and GIF are accepted. Other file types belong in a [Project](/user-guide/projects/overview).
* **Dictation.** Click the microphone to dictate into the composer.
* **Approvals.** Confirmation cards appear under Henry's reply with **Confirm**, **Always allow**, and **Approve all** when there are several. See [Approvals](/user-guide/working-with-henry/approvals).
* **Thinking.** Henry shows a live working line while it runs tools, with a collapsible thinking block. Choose collapsed or expanded in **Settings → Preferences → Thinking in chat**.

## Workspaces

If you belong to more than one workspace, switch between them from the workspace menu. Each workspace has its own members, integrations, memory, and billing. See [Workspaces](/user-guide/account/workspaces).

## iPhone and Mac apps

Native apps for iPhone and Mac are in beta testing. They are chat-first: the same conversations, approvals, and memory, with push notifications for task reports that finish while you are away. The **Channels** page shows their status for your account.
