## Superhuman

Superhuman began as a famously fast email client and has expanded into a broader AI productivity suite. Today it spans Superhuman Go, an assistant that lives inside the apps and tabs you already use with inline suggestions and context-aware chat; Superhuman Mail, its email app with auto drafts, split inbox, auto labels, and auto archive; and Superhuman Docs, a collaborative workspace for documents, tables, data, and workflows.

A large part of the platform is built around agents. You can describe a task in chat or use a visual builder to create an agent, then share it with teammates or publish it to a company directory. Pre-built agents cover common knowledge-work jobs such as preparing for meetings by pulling relevant emails, notes, and docs, turning meeting notes into recaps for each owner, checking claims against company data, and humanising AI-generated text. Superhuman also sits inside the wider Superhuman Platform alongside Grammarly and GPTZero.

Superhuman is a paid product aimed at individuals, teams, and enterprises. The suite integrates with Gmail, Google Calendar, and many workplace tools, and the enterprise tier adds administration and security controls. For exact plan tiers, seat pricing, and included features, check the official pricing page, since packaging has changed significantly as the product has grown beyond email.

## Zero Inbox

Zero Inbox's founding principle is that an email cleaner should not be a black box. Instead of granting a tool permission to delete at will, you connect a mailbox and Zero AI prepares suggested groups — spam, promotions, newsletters, important — for you to review. Nothing is deleted, moved or unsubscribed until you approve it, and you can leave any suggested group untouched. The company pairs that with provider-based sign-in via Google or Microsoft, so you never hand over a mailbox password and can revoke access from your provider's own settings.

Beyond one-off cleanup, the product is built around recurring clutter. One-click unsubscribe handles the senders that keep coming back, with permanent blocking and a tracked history of every unsubscribe action. Inbox insights show how many messages were handled, which categories they fell into, and how inbox health moves over time — useful for spotting the newsletters and promotions that reliably refill an inbox after each sweep. Reviews quoted on the site emphasise speed and the approval step: users describe clearing tens of thousands of emails, and specifically appreciate being asked first.

Zero Inbox works across Gmail, Google Workspace, Outlook and Hotmail, and is aimed well beyond power users — business professionals, freelancers, students, remote workers juggling multiple accounts, and anyone sitting on five or six figures of unread mail. For teams and companies, the company runs a deliberately cautious engagement: start with one authorized source, one measurable email problem and one named operator, build a review queue, record exceptions, and only expand after a written closeout. The site claims more than 30,000 people have used the product, and its privacy documentation is written in plain language deliberately, so the data-handling scope is clear before you connect an account.

**Pricing & Plans:** Freemium. There is a free tier to get started, with paid plans available as usage and controls grow. For businesses, engagement begins with a bounded paid proof — one authorized source, one measurable email problem, one named operator — before any wider rollout, arranged by contacting the team.

- **Approval before every action:** Every cleanup action is proposed first. Review suggested groups, keep any group unchanged, and only then approve the delete, move or unsubscribe — the tool never touches your mailbox unasked.
- **Provider sign-in, no stored password:** Sign in with Google or Microsoft instead of handing over a mailbox password. Access can be revoked from your provider at any time.
- **AI inbox categorization:** Zero AI sorts your inbox into spam, promotions, newsletters and important, so bulk delete and keep decisions can be made in groups rather than message by message.
- **One-click unsubscribe with tracking:** Unsubscribe from any sender with one click, permanently block unwanted newsletters, and keep a record of every unsubscribe action taken.
- **Inbox insights and cleanup history:** See how many emails were cleaned, which categories they fell into, and how your inbox health changes over time.

**Strengths:** Approval step before any message-changing action, so cleanup is reviewable; One-click unsubscribe with permanent blocking and action tracking; Signs in via Google or Microsoft, so no mailbox password is shared; Access can be revoked through your email provider at any time
