Two paid AI email tools. Different shapes. One bolts onto your inbox, the other replaces your email client. Here is the honest comparison plus a third option Outlook users should know about.
Fyxer and Superhuman both promise faster email. They get there in opposite ways. Fyxer connects to your existing Outlook or Gmail account through the Microsoft Graph and Google APIs and adds a layer of AI categorisation, drafting and follow up on top. You keep your email client. Superhuman replaces your email client. You migrate from Outlook to a dedicated app that focuses on speed, keyboard shortcuts and a curated experience, with AI features added on top.
Fyxer Pro is around £40 per user per month. Superhuman is around £33 per user per month. Both require an existing email account. Both have learned to draft replies in your voice from your sent email patterns.
The right choice depends on whether you are willing to leave Outlook. If you are, Superhuman gives you the polished client experience. If you are not, Fyxer adds AI on top of the inbox you already have. There is also a third option, but more on that further down.
SMART Reply is a Microsoft certified Outlook add in. It lives inside Outlook the way Fyxer and Superhuman do not. It learns from your last 400 sent emails, your website, your documents and your customers' websites, then drafts emails, LinkedIn posts and meeting follow ups in your voice. It also covers travel planning, branded booking pages, meeting intelligence and one click filing to OneDrive and SharePoint. £35 per user per month with a 14 day free trial.
Try SMART Reply free for 14 daysSMART Reply is a Microsoft certified add in that runs inside the Outlook UI on desktop and web. No migration. No external server processing your email. Your data stays inside your Microsoft tenant.
Fyxer and Superhuman learn from your sent email patterns. SMART Reply also learns from your website, the documents you upload, and your customers' websites. The drafts sound like you and know your business.
LinkedIn posts and comments, travel planning with diary blocking, branded booking pages with multi person availability, meeting intelligence and one click filing to OneDrive and SharePoint, all in the same price.
Fyxer connects to your existing Outlook account through the Microsoft Graph API and adds AI auto categorisation and drafting on top. Superhuman replaces your email client entirely. If you want to keep working in Outlook, Fyxer is the closer fit. If you are willing to migrate to a different email client and pay for a polished keyboard driven experience, Superhuman is the better fit. Neither lives inside Outlook the way a Microsoft certified add in does.
Superhuman is around £33 per user per month. People who choose Superhuman do so for the keyboard shortcuts, the speed, and the curated experience rather than the AI alone. If your priority is faster email handling and you are comfortable migrating from Outlook, the price is justified. If your priority is AI drafting that sounds like you, there are cheaper and more focused options.
Fyxer connects to Outlook via the Microsoft Graph API, which means a copy of your email metadata is processed on Fyxer servers. It is not an in pane Outlook add in. Drafts and categorisations appear in Outlook, but the work happens outside the Outlook app.
Both tools learn from your sent email patterns. Fyxer's voice match is built into its drafting feature. Superhuman's AI features were added more recently and are less voice focused than Fyxer's. Neither tool incorporates your website, your documents, or your customers' websites into a private knowledge base.
Yes. SMART Reply is a Microsoft certified Outlook add in that lives inside Outlook itself, learns from your last 400 emails, your website, your documents and your customers' websites, and covers LinkedIn posts and comments, travel planning, branded booking pages, meeting intelligence and one click filing to OneDrive and SharePoint. £35 per user per month with a 14 day free trial.
