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.
