Superhuman vs Fyxer in 2026: Pricing, Features, and Which to Choose
Comparing Superhuman and Fyxer with Inbox Zero
Superhuman is a fast, keyboard-first email client you move into. Fyxer is an AI assistant that works inside your existing Gmail or Outlook, drafting replies, sorting email, and taking meeting notes. Inbox Zero sits closer to Fyxer, as an open source layer on top of the inbox you already use.
Superhuman and Fyxer both promise to give you hours back from email, and both use AI to draft replies in your voice. But they are different kinds of product, and that difference matters more than any single feature.
Superhuman is an email client. You stop using the Gmail or Outlook interface and read your mail in Superhuman's app instead, which is built for speed and keyboard shortcuts.
Fyxer is an assistant. It connects to the Gmail or Outlook account you already use, sorts incoming email into categories, drafts replies into your drafts folder, and joins your meetings to take notes. You keep your current inbox.
Below is how they compare on price and features, who each one is best for, and where Inbox Zero, an open source AI email assistant for Gmail and Outlook, fits in.
Prices were checked on Superhuman's and Fyxer's official pricing pages on September 28, 2026. Both change their plans regularly, so confirm before you buy.
Superhuman vs Fyxer pricing
| Plan | Monthly billing | Annual billing | Notes |
|---|---|---|---|
| Superhuman Mail Starter | $30/mo | $25/mo | The client plus core AI |
| Superhuman Mail Business | $40/mo | $33/mo | Adds Auto Drafts, Ask AI, CRM integrations |
| Fyxer Free | $0 | $0 | 400 credits a month; no automatic drafts or inbox sorting |
| Fyxer Pro | $49/mo | $32/mo | Drafts, sorting, meeting notes; credit based |
| Fyxer Team | $99/mo | $64/mo | Shared follow-ups, team reporting |
| Inbox Zero Starter | $20/mo | $18/mo | Drafts, rules, bulk unsubscribe, analytics |
A few things stand out:
- Superhuman's AI drafting is on Business. Auto Drafts, the feature that writes replies before you open an email, requires the $40 per month Business plan. Starter is cheaper but gets you mostly the client.
- Fyxer's paid plans are usage based. Pro includes 3,000 credits per member per month (unlimited for the first three months as a launch offer). Sorting costs a credit per five emails, meeting recording a credit per minute, and chat messages 20 credits each. Heavy users should check how far the credits go.
- Annual billing changes the ranking. On monthly billing Fyxer Pro ($49) costs more than Superhuman Business ($40). On annual billing it's cheaper ($32 vs $33).
If price matters, Inbox Zero starts at $20 per month and includes AI reply drafts on its entry plan. For more detail on Superhuman's tiers, see our Superhuman pricing breakdown.
The real difference: new client vs assistant in your inbox
This is the decision that matters most.
With Superhuman, you commit to a new app. The payoff is speed: a polished interface, keyboard shortcuts for everything, Split Inbox, and fast search. If the way you read and reply to email is the bottleneck, that is exactly what you are paying for.
With Fyxer, nothing about where you read email changes. It works in the background, labels email into categories such as To Respond and FYI, and leaves drafted replies waiting in your drafts folder. The payoff is less work per email rather than faster work per email.
Inbox Zero takes the same approach as Fyxer: it works on top of your existing Gmail or Outlook. The difference is how much control you get over what happens to each email, and that the code is open source.

Who should pick Superhuman
Pick Superhuman if you want a faster email client and you are happy to leave the Gmail or Outlook interface behind. Power users who process hundreds of emails a day with their hands on the keyboard get the most out of it. Budget for Business if AI drafting is the main reason you are buying.
Who should pick Fyxer
Pick Fyxer if you want an assistant that works in the background of your existing inbox, and you want meeting notes and follow-ups from the same product. Its fixed categories are simple to set up and work for many people without any configuration. Check the credit limits against how much email and how many meetings you have.
Why some people pick neither
If you like Fyxer's approach of keeping your current inbox but want more control, or you want software you can inspect, Inbox Zero is worth a look:
- Custom rules in plain English. Tell it what to do with receipts, newsletters, cold outreach, or a specific client, and it labels, archives, forwards, or drafts accordingly.
- Bulk unsubscribe and archive across every sender, with a report of how often you actually read them.
- Reply tracking so you can see what needs a reply and what you are waiting on.
- Open source. The code is on GitHub, and you can self-host it.
- Gmail and Outlook, from $20 per month.
