A chat-native AI COO, or an AI that lives in your inbox
Mira meets you in Slack, Teams, and WhatsApp and runs the business through conversation. this+that meets you in every channel where work shows up (Gmail, Outlook, Slack, Teams, Google Chat, Telegram) and gives you a dedicated task surface, a visual workflow builder, and an open MCP layer. Two real choices for two different shapes of team.
Chat as the operating layer, or messages as the input
Mira's bet is that the right interface for an AI COO is the chat your team already lives in. Slack, Teams, and WhatsApp become the place you talk to the business: ask for a status, ask Mira to chase an invoice, get answers grounded in the SaaS tools she connects to. There is no visual workflow builder by design (their words); progressive autonomy is the mode. this+that's bet is different: the work that needs running shows up as messages across every channel (email matters, not just chat), and the right interface is a universal inbox plus a dedicated task surface (DoBox) plus a visual workflow builder plus an open MCP layer. If your team really lives in Slack and WhatsApp and you want chat-native autonomy with Forward Deployed Engineer support, Mira is a strong fit. If email is still where half the work arrives, or you want to see the workflows you are running, or you want any tool with an API to plug in via open MCP, this+that is built for that shape.
Feature by feature
How the two products compare across the things that matter most.
| Topic | Mira | this+that |
|---|---|---|
| Primary surface | Chat in Slack, Teams, and WhatsApp. You talk to Mira like a colleague; no new app to open. | A universal AI inbox across Gmail, Outlook, Slack, Teams, Google Chat, and Telegram. The inbox is the surface, with DoBox, Calendar, and the assistant alongside. |
| Email coverage | Email is one of the connected SaaS tools Mira reads from. The primary place you interact is chat, not email. | Gmail and Outlook are first-class channels alongside the chat surfaces. Messages from any connected channel produce tasks, drafts, and workflow triggers the same way. |
| First-class. WhatsApp is one of the primary surfaces. | Not supported today. Gmail, Outlook, Slack, Teams, Google Chat, and Telegram are live; Instagram, Facebook Messenger, and others are coming. | |
| Workflow builder | "No workflow builder, by design." Mira runs flows for you based on what she has learned; you do not author them visually. | A visual workflow builder with 32 action types, conditional logic, loops, and sub-agents. Describe a workflow in plain language and the builder generates it; you can edit any step. |
| Task surface | Tasks live in chat; the assistant remembers what is open and chases it. No dedicated task UI surfaced publicly. | DoBox is a dedicated task surface: priority, assignees, due dates, source link back to the message, shared lists, team visibility. |
| Knowledge layer | Long-term memory across WhatsApp, Slack, and the product. Builds an ontology of the organization through SSO and existing permissions. | The Brain: a structured knowledge layer that drafts, the assistant, and workflows all read from and write to. Pages, versions, public and team scopes. |
| Tool integrations | CRM, invoicing, docs, calendars, email, other business tools. Connections handled by Mira without API keys or config; no public open-MCP layer. | Open MCP. HubSpot, GitHub, Jira, Notion, Dropbox, Box are built in; any tool with an API can be connected as a workflow step. |
| Autonomy model | Progressive autonomy: start with suggestions, graduate to full autonomy once trust is earned. Dial back at any time. | Configurable per workflow. Drafts for review, fully automated actions, or approval gates on individual steps. The visual builder shows you which steps need a human. |
| Enterprise controls | SSO, audit logs, BYO models, Forward Deployed Engineers for setup. Inherits existing org permissions. | AWS Bedrock for inference (data stays in AWS, not used to train), message content under dedicated KMS keys (no this+that employee has decrypt access), SOC 2 Type II underway, GDPR/CCPA. No BYO models today. |
| Audience and stage | Founders and SMEs. London-based, seed-stage Binome, EWOR-backed. Free for founders during beta; engineer-supported setup. | Founders, operators, and small teams across tech and agency-style businesses. Free during beta. |
- Chat as the operating layer. If your team genuinely lives in Slack, Teams, and WhatsApp, Mira meets them where they are without asking them to open another app.
- WhatsApp as a first-class channel. Useful for businesses where customers and partners live on WhatsApp.
- Forward Deployed Engineers for setup. White-glove onboarding from a team with Palantir, JP Morgan, and Goldman Sachs roots.
- BYO models. Bring your own foundation model where compliance or cost demands it.
- Progressive-autonomy framing. The dial from suggestion to full autonomy is the explicit product model.
- Strong enterprise posture: SSO inheritance, audit logs, ontology of the organization built on existing permissions.
- Email is a first-class surface, not a side connection. Gmail and Outlook get the same treatment as Slack and Teams: every message produces tasks, drafts, and workflow triggers.
- A dedicated task surface. DoBox shows priority, assignees, due dates, and the link back to the source message, instead of asking you to track work inside a chat thread.
- A visual workflow builder. 32 action types, conditional logic, loops, sub-agents, and plain-language generation. You can see and edit the workflows you are running.
- Open MCP. Any tool with an API can be a workflow step; you are not waiting for an official integration.
- The Brain as a structured knowledge layer. Pages, versions, scopes, and the same content grounds drafts, the assistant, and workflows.
- A unified calendar surface. Full month/week/day/agenda views across every connected Google and Outlook account, with team availability and public booking pages built in.
