Akiflow vs Superhuman

Akiflow is a desktop and mobile planner built around one idea: pull every task into a single inbox, then time-block it on your calendar. It imports tasks from Gmail, Slack, Notion, Asana, Jira, Todoist, ClickUp, Trello and other tools, so requests that arrive in a Slack thread or a starred email do not get lost across separate apps.

The core workflow runs through a keyboard-driven command bar: capture a task from anywhere, triage the inbox, drag items onto Google or Outlook calendars and reschedule with shortcuts. Daily and weekly planning rituals guide you through reviewing what got done and what moves to tomorrow, booking links let others schedule time with you, and an AI assistant can create tasks and plan from natural language. There is no free plan; Akiflow sells a single Pro subscription after a trial, with a lower price for annual billing.

Akiflow fits knowledge workers, managers and founders whose work arrives through many channels and who already plan by time-blocking. It is less suited to casual to-do users or to teams looking for shared project management, since it is primarily a personal tool. Sunsama offers a calmer, more guided daily planning ritual at a similar price, Motion leans harder on automatic AI scheduling, and Todoist with a calendar view is far cheaper if you mainly need a task list. Akiflow's advantage is the breadth of its integrations combined with keyboard speed.

Superhuman is a premium email client for Gmail and Outlook accounts, founded in 2014 by Rahul Vohra in San Francisco. It is built around speed: nearly every action has a keyboard shortcut, the interface is designed to respond instantly, and a guided onboarding teaches users to process email toward inbox zero.

Key features include split inboxes that separate important senders from newsletters and notifications, snippets for reusable text, reminders that bring back threads when nobody replies, scheduled sending, undo send, read statuses and calendar integration. Its AI features write and edit replies in your tone, summarize long threads, auto-label and triage incoming email, and let you ask questions across your mailbox. Pricing is per user per month with Starter, Business and Enterprise tiers; Business adds team features and CRM integrations, and Enterprise adds SSO and security controls. Grammarly acquired Superhuman in 2025 and has since used the Superhuman name for its wider productivity suite.

Superhuman is worth the cost for founders, investors, executives and salespeople who handle hundreds of emails a day, where saving even a few minutes per hour adds up. Light email users will not notice enough difference to justify the price, and it only supports Gmail and Microsoft accounts. Gmail with Gemini or Outlook with Copilot covers basic AI help, Spark offers a cheaper smart inbox, and Shortwave is the closest AI-first alternative for Gmail users.
