Superhuman Mail describes itself as "the most productive email app ever made", and the claim is not marketing noise — it is built for people whose day is genuinely email: keyboard shortcuts instead of mouse trips, a Split Inbox that separates your team and your VIPs from the noise, and AI that labels, archives, summarises and drafts as mail arrives.
Yuki is not that, and cannot pretend to be. Yuki has no inbox to fly through. It connects to Gmail and reads what is inside your mail — the flight confirmation, the hotel booking, the renewal notice, the parcel tracking number, the invoice, the invitation — and turns it into a calendar, a trip itinerary, tracked spending and a list of what you actually owe someone.
The one-line test
Most people who try both discover they are not choosing. Superhuman makes the inbox fast. Yuki makes sure the inbox stops being the only place your life is written down.

Where Superhuman is ahead
It is an email client and Yuki is not, and that single fact covers most of the list. Superhuman gives you a Split Inbox that separates your team, your VIPs and your tools from everything else; keyboard shortcuts that remove the mouse from triage; snippets, send later, snooze, undo send and read statuses; and a follow-up reminder when you send something important and hear nothing back. Yuki has none of these, because Yuki is not where you read your mail.
Superhuman also works where Yuki does not. It supports Outlook as well as Gmail, and runs on Mac, Windows, the web, iOS and Android. Yuki is Gmail only, and mobile only — there is no desktop app and yukihq.com is marketing and account management, not the product.
It is built for teams, which Yuki is not. Shared conversations let a colleague comment on an email without being forwarded it; there are shared drafts, team snippets and team scheduling; HubSpot, Salesforce and Pipedrive sit inside the inbox on the Business plan; and Enterprise brings SSO, SCIM provisioning, audit logs, bring-your-own-key encryption and advanced admin controls. Yuki has no answer to any of that.
And its AI is shipped. Auto Labels, Auto Archive, Auto Summarize, Instant Reply, Instant Event, Auto Drafts and Ask AI are features paying customers use today. Several of Yuki's closest equivalents are not — see the next section, because we would rather you read it here than find out after installing.
What is not shipped on our side
What is shipped, today, for anyone: Gmail connected and read; bookings, bills, renewals, invites, receipts and parcel tracking pulled out of it and turned into calendar events, trips, expenses, subscriptions and tasks; Focus emails, the short list of mail that actually needs you, on Pro; on-demand AI reply suggestions on Pro, which you can send with one tap; groups with expense splitting and settle-up; people and occasions; and trip itineraries built from your own confirmations.
Where Yuki is ahead
- It does the thing after the inbox. A confirmation becomes a calendar event and a trip; a receipt becomes tracked spending; a renewal notice becomes a subscription you can see before it charges you.
- It is €3.99 a month for a person, not $25 a month for a seat — and free to download, with a 30-day trial and no card.
- It works for more than one person: couples, families, flatmates and co-parents share tasks, lists, plans and costs, with expense splitting and settle-up.
- It keeps the people in your life rather than a contact list — birthdays, occasions, what you owe each other, what you have planned together.
- EU data residency end to end, no training on your data, and an independent CASA Tier 2 assessment in March 2026.
- It speaks 23 languages.
A word on data, since both of us read your mail
Superhuman is explicit that its AI subprocessors are barred from training on your content: "We do not, and will not, allow any AI subprocessor to use your data for model training." Its own privacy policy is separate on that point — it says Superhuman uses information it collects to train its AI models, and that you decide via a training control in your account settings. Both statements are theirs and both are worth reading before you connect a mailbox. Superhuman is a US company and relies on the EU–U.S. Data Privacy Framework and standard contractual clauses for transfers out of the EEA and UK.
Yuki does not train any model on your data, and there is no setting to find, because it is not a setting. Data stays in the EU end to end, and Yuki passed an independent CASA Tier 2 assessment in March 2026.
The structural difference
Superhuman makes the inbox faster. Yuki makes the inbox matter less — because the things buried in it are already in your calendar, your trip, your budget and your shared list before you get round to reading them. One is a better place to do email. The other is an attempt to stop email being the place your life is stored.
If email is your job, buy Superhuman. If email is just where your life arrives, try Yuki — and if both are true, they do not get in each other's way.
Yuki is free on iOS and Android, with a 30-day Pro trial and no card required.
