Superhuman Go Review: An AI Assistant That Works Where You Do
ProductivityFreemiumSuperhuman Go puts an AI assistant inside the apps you already use. It suggests edits as you type, reads what is on your screen, drafts email replies, and briefs you in Slack without sending you to a separate chat window.
What Is Superhuman Go and How Does It Work?
Superhuman Go inverts the usual assistant relationship. Rather than a page you go to, it is a layer that sits inside the desktop app, the browser tab, and the phone. You install it once, and it follows you: draft a reply in Mail, highlight a paragraph in a doc, summarise a thread in Slack, and the same assistant is present in each case with the context of that moment already attached.
The screen-awareness piece is what makes this more than a notification system. Because Go can read what is displayed, a question can refer to the thing you are looking at. The connector layer is the other half, because context that lives in a connected application, a calendar, a CRM record, a ticket, is what turns a generic sentence into a specific answer. Neither half works well alone, which is why the free plan feels thinner than its feature list suggests.
Superhuman Go Connectors: What Each Plan Can Reach
The connector list widens as you climb, and this is the single biggest difference between the plans. Pro opens the personal and everyday set. Business adds the project and support tools a team already runs on. Enterprise adds the systems that hold customer and employee records.
Because the ladder is fixed rather than open-ended, it is worth checking the list against your stack before signing up. A curated set that already contains everything you need is an advantage. A curated set that is missing one system you depend on is a hard ceiling, and there is no self-serve way around it.
- Free: no third-party connectors, only your open tabs and apps
- Pro: Superhuman Mail, Gmail, Calendar, Outlook and Slack
- Business: adds Jira, Linear, Asana, Confluence and Zendesk
- Enterprise: adds Salesforce, HubSpot, Workday and ServiceNow
- The product page describes the wider catalogue as 100+ apps, with the per-plan list above being the guaranteed set
Inside Superhuman Go's Agent Layer: Grammarly, Email Assistant and Custom Agents
Go describes itself as managing a team of agents rather than running one model, and that framing is doing real work in the product. Grammarly's writing intelligence is embedded as one of those agents, which is the clearest single reason to pick this over a generic assistant if your work is text-heavy.
Email Assistant is the agent with the most obvious job description: it drafts replies, works through inbox clutter, and follows up on your behalf. It is a Pro feature, so it sits behind the paywall rather than in the free preview.
Building your own agents is the part with the most ambiguity. The product page says Pro, Business and Enterprise users can all build custom agents, while the feature table marks Pro as limited access, Business as expanded, and Enterprise as full. Either way the practical reading is the same: experimenting is a Pro activity, and running a fleet of your own agents is a Business and Enterprise one.

Pros and Cons
Superhuman Go is a well-built assistant for people whose work is reading and writing, priced per seat, with the integrations that matter gated behind the paid tiers. The free plan is enough to judge the interaction model and not enough to run on day to day. The gains are real for anyone who lives in their inbox and their documents, and thin for anyone whose work is visual, technical, or automatable.
Pros
- Help from Superhuman Go arrives in the window you are already in, so there is no separate chat tab to manage
- Screen awareness means you can ask about the page in front of you without pasting or describing it
- Grammarly's writing intelligence is built in, which makes drafting and editing stronger than a generic assistant
- The free plan is usable on its own: inline suggestions, chat with open tabs, shareable docs, and synced conversations
- Email Assistant on Pro drafts replies and works through inbox clutter, which is more than most assistants attempt
- Enterprise connectors reach into Salesforce, HubSpot, Workday and ServiceNow rather than stopping at Slack
Cons
- The useful integrations start at $12 per member per month, so the free plan is a genuine preview rather than a working substitute
- Custom agent building is limited on Pro and only expands at Business and Enterprise, making the agent story mostly a paid-team feature
- The documented scope of Superhuman Go is text, with no image generation, code execution, or workflow builder listed in the product materials
- Official pages disagree on one platform, with the pricing page FAQ still calling the Windows desktop app upcoming while the help centre publishes a full Windows install guide
- You are buying into the Grammarly ecosystem, and the connector list is a curated set rather than an open app store
- Per-seat pricing climbs with headcount and there is no published enterprise rate to forecast against
Frequently Asked Questions
Common questions about Superhuman Go, answered.
What is Superhuman Go?
An AI assistant that runs inside your apps instead of in a separate chat window. It offers inline suggestions as you type, can read what is on your screen, connects to your email, calendar and work tools for grounding, and manages a set of agents that includes Grammarly's writing intelligence. It ships as a desktop app for Mac and Windows, Chrome and Edge extensions, a web app, and iOS and Android mobile apps.
Is Superhuman Go free?
Yes, and the free plan does not expire. It includes basic inline suggestions, chat with your open tabs and apps, editable shareable docs, and conversations synced across desktop, mobile and browser. What it does not include is the paid connector set, Email Assistant, customisable suggestions, or custom agent building.
How much does Superhuman Go cost?
Pro is $12 per member per month when billed annually, or $15 monthly. Business is $33 per member per month annually, or $40 monthly. Enterprise is quoted directly. Because billing is per seat, the total follows your headcount rather than your usage.
Which apps does Superhuman Go connect to?
Pro connects Superhuman Mail, Gmail, Calendar, Outlook and Slack. Business adds Jira, Linear, Asana, Confluence and Zendesk. Enterprise adds Salesforce, HubSpot, Workday and ServiceNow. The product page refers to a wider catalogue of 100+ apps, so the per-plan list is best read as the guaranteed set rather than the whole list.
Can you build your own agents in Superhuman Go?
Yes, on paid plans, with the depth depending on the tier. The feature table marks custom agents as limited on Pro, expanded on Business and full on Enterprise, while the product page says Pro, Business and Enterprise users can all build them. The practical difference is that experimenting is a Pro activity and operating a fleet of your own agents is a Business and Enterprise one.
Does Superhuman Go train AI models on your data?
The published plan comparison lists model training as opt-out on Free, Pro and Business, and off by default on Enterprise. The same table lists SAML SSO, SCIM, SOC 2 Type 2 and audit logs, and notes that HIPAA coverage extends to Go. Bring-your-own-key is listed as applying to Grammarly and Mail only, not to Go.
Which platforms does Superhuman Go run on?
The help centre lists desktop apps for Windows and Mac, extensions for Chrome and Edge, a web app at go.superhuman.com, and iOS and Android mobile apps. It also notes that connectors, which pull in context from Gmail, Slack and Google Calendar, are available only on Pro-level subscriptions and above. One inconsistency is worth knowing: the FAQ on the pricing page still says the Windows desktop app is coming soon, while the help centre publishes a complete Windows install guide. The help-centre version looks more current, but confirm availability for your own operating system before you commit.
