this+that vs Slashy
A beautiful Gmail inbox vs your whole team’s stack.
Slashy is a good AI-native email client. But it works with Gmail only, lives in iMessage and Slack, and is built around one person’s inbox. this+that works across Gmail and Outlook, Teams, Slack, and Google Chat, turns every message into tracked, assignable team work, and runs the follow-through, for less per seat.
A polished single-inbox client vs a team-wide assistant
Slashy does real things well: AI drafts in your voice, an inline writing assistant, a self-improving memory that learns your tone and contacts, read tracking, and a fast keyboard-first client. It’s already SOC 2 Type II certified. If you live entirely in Gmail and want a sharper personal inbox, it delivers. this+that’s built for a different problem. It treats Gmail, Outlook, Teams, Slack, and Google Chat as one stream of incoming work, extracts the tasks and commitments buried in those messages, assigns them to the right teammate, and runs workflows that handle what comes next. Slashy supports Gmail only today (Outlook is “coming soon”) and is priced per seat for individuals. If your team isn’t all on Gmail, or you need work to leave one person’s head, that is the distinction that matters.
Feature by feature
How the two products compare across the things that matter most.
| Topic | Slashy | this+that |
|---|---|---|
| Core use case | Personal productivity. A faster, smarter Gmail inbox that drafts replies and handles routine email. | Team work management. Extract tasks from every channel, assign them, and automate the follow-through. |
| Email providers | Gmail and Google Workspace only. Outlook support is “coming soon” per their own FAQ. | Gmail and Outlook / Microsoft 365, both fully supported today. |
| Channels beyond email | Slack, plus an iMessage/SMS line for texting the assistant. No Microsoft Teams, no Google Chat. | Slack, Teams, and Google Chat as managed channels: the assistant reads them and turns messages into tasks and workflows, plus Google and Outlook calendars. |
| AI drafting | Strong. Voice-trained drafts and an inline assistant to rewrite, shorten, or retone. A real strength. | AI draft replies and emails, both interactively and as a workflow action. |
| AI memory / personalization | Self-improving memory built from the email you send and receive, with a dedicated agent that organizes it. A real strength. | Learns your tone and VIP context from your messages to personalize drafts. |
| Task extraction | Turns important emails into tracked to-dos and chases replies, inside one person’s inbox. | DoBox reads every message across channels and extracts requests, decisions, commitments, and deadlines. |
| Task assignment & team view | Individual-oriented. Team comments and team scheduling, but no shared task assignment. | Assign extracted work to any teammate with due dates, priorities, and a shared task view. |
| Workflow automation | AI automations triggered on incoming email, calendar events, opens, or a schedule. Genuinely capable. | A plain-language builder, conditional logic, loops, and AI decisions inside workflows. |
| Calendar | Manage your calendar with AI, calendar sidebar, and turn emails into events. | Calendar actions as workflow steps: create, RSVP, reschedule, manage attendees. |
| Integrations | Attio (HubSpot and Granola via Attio). Exposes your inbox to other agents over MCP. | HubSpot via MCP, plus GitHub, Jira, Notion, and any tool with an API through the open MCP standard. |
| Read / open tracking | Yes. See when, where, and how many times a recipient opened your email. | Not available. |
| Security | SOC 2 Type II certified today. | SOC 2 Type I as of July 31, 2026. Type II is underway, so Slashy is still ahead of us here. |
| Pricing | $30 per seat per month, or $25 billed annually. 7-day trial. | Free for 30 days. Then $35 per user per month, or $29 billed annually. |

What’s Slashy?
Slashy is an AI email client for Gmail and Google Workspace. It drafts replies in your voice, offers an inline writing assistant, and builds a self-improving memory of your tone and contacts. It also does read and open tracking, so you can see who opened a message and when, and the client itself is fast and keyboard-first. It’s SOC 2 Type II certified, which is the harder of the two reports to earn and something we have not completed.
How much does Slashy cost?
Slashy is $30 per seat per month, or $25 per seat billed annually, on its Professional plan, with a 7-day trial. Enterprise controls and support are available separately. For comparison, this+that is free for 30 days and $35 per user per month afterwards, or $29 on annual billing, so we are the more expensive of the two once the trial ends.
Who should choose Slashy?
If you live entirely in Gmail and want a sharper personal inbox, Slashy delivers, and it is cheaper than we will be. The read tracking is a feature we do not have, the SOC 2 Type II certification matters for some buyers, and the client is a pleasure to use. Individuals and Gmail-only teams whose problem is email itself should look at Slashy first.
