# Swizero > The finite inbox for Gmail. Swizero turns your inbox into a ranked stack of AI-scored cards, so every email session has a finish line. Most email apps give you better tools to manage an endless inbox. Swizero gives you a finish line instead. ## How It Works Swizero's AI ranking algorithm scores every email in your inbox by importance and surfaces only the ones that actually need your attention as a ranked stack of cards. Each card is distilled to its essence by an AI summary. Four-direction swipes handle every outcome without menus: Down to archive, Left to clear, Right to flag, Up to reply — one-handed, in seconds. When the stack is empty, email is finished for the session. AI drafts replies for you. Smart follow-up reminders surface when a thread needs action. Nothing sends without explicit user approval. Every action is undoable. ## Who It's For Successful professionals and founders who need email done, not just managed. If you use email every day but have work that matters more, Swizero clears what needs attention and gets out of your way. Anyone with a daily email habit and real priorities will find value. ## Why Swizero No other email app brings you what matters in as direct and clean a flow. Superhuman, Hey, Spark, and Shortwave all make different versions of the same bet: give users more control over their inbox stream. Swizero makes a different bet — shrink the problem to only what needs you. The result is a cleaner interface, faster decisions, and nothing unnecessary in the way. ## Key Pages - [Home](https://www.swizero.com): Product landing page with features, demo, and waitlist signup - [Get Started](https://www.swizero.com/get-started): Full conversion landing page — problem, mechanism, trust, use cases, proof, and CTA - [Pricing](https://www.swizero.com/pricing): Swizero Premium — $9.99/month or $79.99/year (~$6.67/mo billed annually) - [Security](https://www.swizero.com/security): Trust page with architecture diagram, privacy Q&A, zero-retention cloud processing explained - [For Founders](https://www.swizero.com/founders): ICP landing page for startup founders with pain grid and Swizero Run walkthrough - [Calculator](https://www.swizero.com/calculator): Interactive email-time calculator showing weekly interruptions and Swizero Run recommendation - [Download](https://www.swizero.com/download): Private beta status page with visual timeline - [FAQ](https://www.swizero.com/faq): Frequently asked questions about Swizero, billing, privacy, and features - [Blog](https://www.swizero.com/blog): Articles on email productivity, AI in email, and digital wellness - [Contact](https://www.swizero.com/contact): Get in touch with the Swizero team - [Privacy Policy](https://www.swizero.com/privacy): Privacy policy and data handling practices - [Terms of Service](https://www.swizero.com/terms): Terms of service ## Comparison Pages - [Swizero vs Superhuman](https://www.swizero.com/swizero-vs-superhuman): Finite inbox vs speed tools — when to choose each - [Swizero vs Shortwave](https://www.swizero.com/swizero-vs-shortwave): Finite session model vs AI-powered inbox bundling - [Swizero vs Spark](https://www.swizero.com/swizero-vs-spark): Completion-focused vs organization-focused email - [Swizero vs HEY](https://www.swizero.com/swizero-vs-hey): Gmail companion layer vs full email reinvention - [Swizero vs Apple Mail](https://www.swizero.com/swizero-vs-apple-mail): AI annotations on a list vs a ranked stack you finish - [Swizero vs Gmail](https://www.swizero.com/swizero-vs-gmail): Keep Gmail, add a daily session with a finish line - [Swizero vs Edison Mail](https://www.swizero.com/swizero-vs-edison-mail): Prettier inbox vs finite inbox — two mobile-first approaches - [Swizero vs Canary Mail](https://www.swizero.com/swizero-vs-canary-mail): Encryption-first vs completion-first email privacy - [Gmail Inbox Triage](https://www.swizero.com/gmail-inbox-triage): How Swizero automates Gmail triage with a ranked stack finish line - [Privacy-First AI Email](https://www.swizero.com/privacy-first-ai-email): Zero-retention AI email processing — how Swizero handles data ## Blog Posts - [Welcome to Swizero](https://www.swizero.com/blog/welcome-to-swizero): Introducing Swizero — the email app that reduces your inbox to a fixed card limit.
