More channels, or deeper execution.
InboxAgents connects more communication channels than any competitor — Gmail, Outlook, WhatsApp, Slack, Discord, Telegram, iMessage, Signal, LinkedIn, Instagram, Twitter DMs, and Facebook Messenger. That breadth is genuinely impressive. this+that covers fewer channels today, but goes further with each one: it extracts structured tasks from conversations, tracks commitments across your team, and runs automated workflows — not just routing messages and surfacing reminders.
Aggregation and routing vs. extraction and execution
InboxAgents' thesis is that communication overload is a channel problem — you have too many inboxes, and you need one place that brings them all together with AI agents that learn your patterns. That is a real problem and InboxAgents solves it well. this+that's thesis is different: the harder problem is not finding messages, it is making sure the work those messages create actually gets done. Every conversation creates tasks, commitments, and follow-ups that get lost. this+that extracts that work into DoBox — a persistent, structured task manager — and then runs automated workflows to handle the execution. If your pain is too many channels to monitor, InboxAgents is worth a look. If your pain is that work gets buried or forgotten, this+that is built for that.
Feature by feature
How the two products compare across the things that matter most.
| Topic | InboxAgents | this+that |
|---|---|---|
| Core philosophy | One unified inbox across every channel you use. AI agents learn your patterns and route, categorize, and surface what matters most. | Extract the work that lives inside messages. Turn conversations into trackable tasks and automated workflows so nothing gets missed. |
| Channel coverage | The broadest coverage available: Gmail, Outlook, WhatsApp, Slack, Discord, Telegram, iMessage, Signal, LinkedIn, Instagram, Twitter DMs, Facebook Messenger. | Gmail, Outlook, Slack, Teams, Google Calendar, and Outlook Calendar. Fewer channels, deeper integration with each. |
| AI agents | Custom AI agents that learn your business rules over 3-5 days and personalize over 2-3 weeks. Focused on categorization, routing, and identifying revenue opportunities. | AI reasoning as a workflow step — used for decision-making, task classification, drafting replies, and branching logic in automations. |
| Task extraction | Not available as a persistent layer. Follow-up reminders and meeting scheduling are surfaced, but there is no structured task manager. | Automatic. DoBox reads every conversation and extracts requests, decisions, follow-ups, commitments, and deadlines as trackable, assignable tasks. |
| Workflow automation | Auto-routing, follow-up reminders, meeting scheduling, invoice tracking, and lead management. Rule-based with exclusion settings. No visual workflow builder. | Full workflow builder. 32 action types. Plain-language creation. IF/ELSE branching, loops, sub-agents. Workflows are not limited to inbox triggers or a fixed rule set. |
| Daily briefings | AI-generated daily briefings that surface critical updates and revenue opportunities across all connected channels. | Not a briefing-first product. Incoming work is surfaced continuously in DoBox as tasks rather than consolidated into a once-a-day digest. |
| Team features | Primarily designed for individual small business owners. Limited team features. | Shared task view, task assignment, workflow delegation to teammates. Work-level coordination across channels and people. |
| External integrations | Connects to a set of business apps for lead, invoice, and meeting workflows. No open integration standard. | Open MCP standard. GitHub, Notion, Jira, Dropbox, HubSpot, and any tool with an API. |
| Calendar integration | Meeting scheduling from within the unified inbox. | Calendar automation as workflow steps: RSVP, create events, reschedule, manage attendees across Google and Outlook Calendar. |
| Pricing | 30-day free trial. Pro plan unlocks additional platform connections. | Free tier available. No credit card required to start. |
