A smarter inbox, or finished work.
Gmail AI (powered by Gemini) is a genuinely useful layer on top of one of the world's most-used email products. this+that is an AI agent that reads your messages and handles what comes next — tasks extracted, workflows run, your team in the loop. One makes Gmail smarter. The other makes the work that comes from email happen automatically.
A layer on email vs. an agent on top of it
Gmail AI's thesis is enhancement: summarize threads, surface priorities, help you write faster — all inside the Gmail experience you already know. It's remarkably low-friction because it's already there. this+that's thesis is delegation: don't just see what matters in your inbox — have the work that follows from it handled automatically, regardless of whether you're on Gmail, Outlook, Slack, or Teams. If you want your Gmail to feel smarter, Gmail AI delivers that for free. If you want your inbox to stop creating open loops in your day, this+that is built for that.
Feature by feature
How the two products compare across the things that matter most.
| Topic | Gmail AI | this+that |
|---|---|---|
| Core philosophy | Make Gmail smarter for 2B+ existing users. Summarization, prioritization, and composition assistance inside the Gmail interface. | Delegate the work that follows messages. Extract tasks, run workflows, keep teams in sync — without you managing it manually. |
| Task extraction | Gemini can extract tasks from email and surface them in Google Tasks. Individual tasks per email rather than a persistent cross-inbox layer with assignment, due dates, and priorities. | Automatic. DoBox reads every conversation and extracts requests, decisions, follow-ups, commitments, and deadlines as trackable, assignable tasks. |
| Workflow automation | Google Workspace Studio is now GA on all Business and Enterprise plans — a no-code workflow builder powered by Gemini. Workflows are scoped to Google Workspace apps (Docs, Sheets, Drive, Meet, Gmail). | Full workflow builder. 32 action types. Plain-language creation. IF/ELSE branching, loops, and sub-agents across any connected tool. |
| Email provider support | Gmail only. | Gmail and Outlook. Works with whatever your team uses. |
| Channels | Email only. Cannot read Slack or Teams messages. | Gmail, Outlook, Slack, Teams, Google Calendar, and Outlook Calendar treated as one stream of incoming work. |
| AI composition | Help Me Write is genuinely useful: full drafts, tone adjustments, length changes, inline suggestions while composing. | AI draft replies and emails as workflow actions. Useful in automation context; not optimized for manual composition UX. |
| Thread summarization | One-click AI Overviews on long threads. Works well for catching up on buried conversations. | Not a standalone summarization feature. Context is used within task extraction and workflow decisions. |
| Calendar integration | Tight Calendar integration — event creation and updates suggested from email context. | Calendar automation as workflow steps: RSVP, create events, reschedule, manage attendees. |
| External integrations | Google ecosystem only — Drive, Docs, Sheets, Meet. No open integration standard. | Open MCP standard. GitHub, Notion, Jira, Dropbox, HubSpot, and any tool with an API. |
| Team features | No shared task view or workflow coordination. Individual productivity enhancement. | Shared task view, task assignment, workflow delegation to teammates. Work-level coordination, not just message-level. |
| Cost | Included with Gmail / Google Workspace — zero additional cost. | Separate subscription. Free tier available. |
