What Are Tools

When you give Dex a task, it breaks it down into tool calls. Each app exposes a set of tools (read, write, search, etc.), and Dex chains them together to complete multi-step workflows. The AI decides which tools to use based on your prompt and available context.

Integration Tools

Every connected app provides tools specific to its capabilities:

• Gmail, send email, search inbox, read threads, manage labels.
• Google Calendar, create/update events, check availability, list upcoming meetings.
• Slack, send messages (as bot or as you), browse channels, search conversations.
• Notion, create pages, search databases, update entries.
• Google Sheets, read cells, update ranges, append rows.
• Linear, create issues, update status, search projects.
• Salesforce / HubSpot / Attio, manage contacts, deals, accounts.

Tools from all connected apps are available in every conversation. Dex selects the right ones automatically. You can manage tool permissions per app from the dashboard.

Browser Tools

Always available, regardless of connected apps:

• Read page content: extract text or screenshot from any tab.
• Navigate: open URLs, batch-open links, create tab groups.
• Search history: query browsing history with time filters.
• Tab management: focus, close, group, ungroup tabs.
• Browser use mode: full point-and-click automation via CDP (see details).

System Tools

Internal tools Dex uses behind the scenes:

• Memory search: retrieve relevant memories mid-conversation.
• Memory upsert: save new information to your memory.
• Automation management: create, list, update, delete automations.
• File system: read and write skills, snippets, and other persistent files.
