The web app at 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.
  • 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.
  • 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.

​
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.
