Email, quietly organised.
Sotto uses AI to sort your inbox so you never miss what matters and never click what doesn't.
Sotto uses AI to sort your inbox so you never miss what matters and never click what doesn't.
All your inboxes. Intelligently sorted.
01 — Zero-click email
Your order has shipped. Sarah accepted your invite. Your subscription renewed. These don't need a reply — they just need to exist somewhere quiet. Sotto recognises them and moves them out of your way automatically. No rules to write. No clicks required.
02 — Classification
AI classifies every email into categories that make sense. Bills arrive in one place. Security alerts in another. Newsletters, receipts, action items — each in their own lane. You set the rules, add your own categories, and Sotto learns.
03 — AI search
Forget digging through threads. Ask Sotto a question in plain language and get a real answer. "What did we agree on pricing?" "When does my subscription renew?" Sotto searches your email, reads the context, and tells you — with links to the original messages.
04 — Smart replies
Sotto drafts replies for you. Review the suggestion, fill in the blanks where your input is needed, and send. No more staring at a blank compose window. BeforeSend rules catch mistakes on the way out — wrong recipient, missing attachment, sensitive content.
05 — All accounts
Connect all your accounts — work, personal, side project — and see everything in a single sorted stream. Colour-coded dots tell you which account at a glance. No more switching between tabs. Gmail today, Microsoft 365 and Outlook coming soon.
06 — Keyboard-first
Navigate, archive, reply, switch between inbox and notifications — all without touching the mouse. Every action has a shortcut. Sotto is designed for people who live in their inbox and want to move fast.
Coming soon
Sotto is growing into your complete productivity layer — not just email, but everything around it.
Calendar
Smart scheduling with suggestions based on your email context. See what's coming without leaving your inbox.
Tasks
Turn emails into tasks with a single keystroke. Track what needs doing — not how many unread messages you have.
Automation
Receipts to Xero. Updates to Asana. Invoices filed automatically. Let Sotto handle the busywork so you don't have to.
Your email is yours. Sotto stores everything locally on your machine. We never have access to the content of your messages.
Private
All email data lives in a local database on your computer. Sotto has no server that stores your messages. Ever.
Secure
OAuth tokens and API keys are encrypted by your operating system's keychain. All external communication over HTTPS.
Transparent
AI classification uses Anthropic's API. Sender logos use logo.dev. Our privacy policy explains exactly what goes where.
