this+that vs Superhuman
Speed through your inbox, or let it work for you.
Superhuman is the fastest email client ever made. this+that is an AI agent that reads your messages and handles what comes next — tasks extracted, workflows run, your team in the loop. Different tools. Different jobs.
The short version
Two genuinely different philosophies
Superhuman's thesis is speed: get you to inbox zero faster, help you reply better, make email feel effortless. It's exceptional at that. this+that's thesis is delegation: don't just move through the messages faster — have the work that comes out of them handled automatically. If you want to be the fastest human in your inbox, Superhuman is the better choice. If you want your inbox to create fewer 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 | Superhuman | this+that |
|---|---|---|
| Core philosophy | Make you faster. Sub-100ms keyboard interactions. You process every message; it just helps you move. | Delegate the work that follows messages. Extract tasks, run workflows, keep teams in sync — without you managing it manually. |
| Task extraction | Not available. You read the email and decide what needs to happen. | Automatic. DoBox reads every conversation and extracts requests, decisions, follow-ups, commitments, and deadlines. |
| Workflow automation | Not available. AI assists you; it does not run processes autonomously. | Full workflow builder. 32 action types. Plain-language creation. IF/ELSE branching, loops, and sub-agents. |
| Team features | Shared Conversations, Team Comments, Team Read Statuses, Team Snippets. Strong team email coordination — visibility into who has read and replied to what. | Shared task view, task assignment, workflow delegation to teammates. Work-level coordination, not just message-level. |
| AI drafts | Instant Reply drafts in your voice. Learned from your writing. Strong and polished. | AI draft replies and emails as workflow actions. Less personalized-to-voice, more useful in automation context. |
| CRM | Salesforce and HubSpot sidebar. Deal status, contact history, recent opens, automatic reminders. | HubSpot via MCP. Any CRM with an API can be connected as a workflow step. |
| Channels | Email only (Gmail and Outlook). No Slack, Teams, or calendar automation. | Gmail, Outlook, Slack, Teams, Google Calendar, Outlook Calendar. |
| External integrations | CRM sidebar (Salesforce, HubSpot) and a Slack integration. No open integration standard for arbitrary tool connections. | Open MCP standard. GitHub, Notion, Jira, Dropbox, Box built-in. Connect any tool with an API. |
| Speed / keyboard UX | Best in class. The product was designed ground-up for keyboard-first speed. | Not a focus. this+that is used through your existing email client, not as a replacement for it. |
| Send timing | Smart Send — optimizes delivery time for each recipient. | Not available. |
