I get asked this question a lot:
If you’re serious about email productivity, should you go all in on Superhuman’s platform, or use Fyxer, which plugs into the inbox you already have?
And I get it. If you’ve ever watched a Superhuman demo, it looks slick, and it can make Gmail or Outlook feel like you’re driving a bus without power steering. But at the same time, Fyxer is changing the game in a completely different direction: helping you to spend less time in your inbox altogether.
I’m going to break down how I think about these two email tools: what they’re great for, where they fall short and which one I personally use every day.
And after testing both, I’ve found a winner. But you’ll need to read to the end for that reveal.
Brand new cockpit, or a smart assistant in the cockpit you’ve already mastered?
Let’s start with the biggest difference between the two tools: where they live.
Superhuman: a new email client
Superhuman is a dedicated email platform. You don’t “add it” to your workflow. Instead, you move your whole email experience into their interface.
Its goal is to make you faster at doing email. The whole product is built around speed and control, designed for people who want to become power users. You’ll find:
- Keyboard shortcuts
- A clean, minimal layout
- A workflow that rewards people who live in their inbox
- AI features to help draft replies and stay on top of follow-ups
Fyxer: an AI email assistant that plugs into Gmail or Outlook
Fyxer doesn’t replace your inbox. Instead, it connects directly to Gmail or Outlook and sits on top of the tools you already use. It’s an email assistant, yes, but it also goes beyond your inbox. It can:
- Write draft replies in your voice
- Organize and categorize your inbox
- Create draft follow-ups
- Help with personal and team scheduling
- Join meetings to take notes and pull out actions
So, Superhuman is like switching to a brand new cockpit. Fyxer is like hiring a capable assistant in the cockpit you already know. That distinction matters, especially if you’re running a team. More on that later.
Speed vs cognitive load
Most Superhuman reviews focus on speed. And Superhuman is fast. If you care about shaving time off every email interaction, it’s genuinely impressive.
But for me, the real question is:
Do I want to get more done inside my inbox? Or
Do I want to get more done outside my inbox?
Superhuman helps you move faster through email
Superhuman is built for people who are happy to learn a new system to go faster. If you love mastering tools, enjoy shortcuts, and want to be extremely hands-on with email, Superhuman can be a great experience.
Fyxer reduces the amount of email work you have to do at all
Fyxer is built to reduce friction, and that starts from Day 1. It lives inside your existing inbox, which means there’s almost no learning curve. You keep your workflow and everything looks the same (albeit organized).
Instead of focusing on how quickly you can process emails, it focuses on removing the need for you to handle so much of the process personally.
So to summarize: Superhuman speeds up the work while Fyxer takes on the work.
Context and tone
People have asked, “Can both tools write like me?”. Yes, to a point. Both Superhuman and Fyxer are designed to learn your tone and style from previous emails. Both can help you reply faster by generating drafts.
But the difference lies in the role you want AI to play in your workflow.
Superhuman gives you a head start, but keeps you close to the keyboard
With Superhuman, you still feel like the pilot. The AI is there to speed you up, but the product is built around you being in control of every message. You’re still writing everything yourself. If you enjoy email as a craft — and some people genuinely do — that’s a good thing.
Fyxer aims to get you closer to “Send”
With Fyxer, you can treat it more like a real assistant. It can handle the first pass on replies, learning from your inbox and calls to write in your tone. It can also take meeting notes and find a slot for the group call that you're already late scheduling.
The other advantage here is context. Fyxer works across email and meetings. When you use it for both, the information Fyxer retains directly improves your drafts, follow-ups, and actions. And in the long term, once that context exists at a team level, insights and learnings emerge without anyone having to share them explicitly.
Workflow and team rollout
This is where the comparison gets practical. When choosing an email productivity tool, you need to consider your wider work environment.
Why Superhuman works for solo operators or small teams
If you’re a solo operator or running a small team where everyone is eager to adopt new tools, Superhuman can be a solid choice.
It works when:
- Your whole team buys into the Superhuman interface
- Everyone wants to become faster and more structured in email
- You want a culture of optimisation and control
The big trade-off is that you’re asking the team to switch platforms. People have to want to learn it. And if they don’t, it becomes another tool that only half the team uses.
Why Fyxer is the better fit for teams
Fyxer is easy to roll out because it integrates directly with Gmail and Outlook. You're not forcing a workflow shift. You’re improving output inside the tools they already use.
That matters a lot if you’re working with:
- Mixed skill levels
- Executives who want less admin, immediately
- Teams that are already locked into Google Workspace or Microsoft 365 subscriptions
- Larger enterprise orgs where adoption is make or break for a new tool
Let’s be honest, Gmail and Outlook are hard to replace. Most teams have spent years integrating platforms like Salesforce, HubSpot, and other internal systems to work with these email providers. Superhuman users often accept workarounds because speed matters more to them. But for established teams, staying inside that existing ecosystem removes friction.
Superhuman vs Fyxer: quick feature comparison
Here’s the cleanest way I’d summarise the differences:
So which platform wins? It depends on who you are.
Here’s the honest answer.
Choose Superhuman if:
- You love email
- You enjoy mastering tools
- You want to optimise your workflow
- You’re happy to switch to a new email platform
- You want speed and control
Choose Fyxer if:
- You want to spend less overall time in your inbox
- You don’t want to, or have time to, learn a new platform
- You’re leading a team and need adoption to be easy
- You want something that behaves like an assistant, not a new app
- You want help with follow-ups, scheduling, and meeting notes as well as email
My personal verdict: why I chose Fyxer
Superhuman helped process emails faster. But Fyxer helps you process fewer emails by letting you delegate the first draft, follow-ups, scheduling, and meeting admin. And because it connects email and meetings in one place, it gets smarter the more you use it.
I’m running a business, and I don’t need a faster inbox; I want fewer hours in my inbox. That’s why I chose Fyxer.
Frequently asked questions
Is Fyxer a Superhuman alternative?

Does Fyxer work with Gmail and Outlook?
Yes. Fyxer connects directly to Gmail and Outlook and works inside the email and calendar tools you already use.
Is Fyxer or Superhuman better for teams?
If you have a team of power users who want to adopt a new interface, Superhuman can be a good fit. But for larger teams or mixed skill levels, Fyxer will be easier to roll out because it doesn’t require switching email platforms.
Is Fyxer or Superhuman better for executives and founders?
If you’re a founder, exec, or operator who wants to get out of the inbox as quickly as possible, Fyxer is the better fit because it’s designed around delegation, not speed.
