Mocca is a desktop email client that connects to your existing inbox and runs an LLM on your machine to classify mail, curate the inbox, and apply rules you write in plain English. No email or content leaves your computer.
Not filters, not keyword search — the model reads each email's content. All on your machine.
The AI reads each email and decides what's actually for you — personal mail, orders, bank alerts — and keeps promotions, newsletters and notifications out. It judges the content, not a list of sender rules you have to maintain.
Write a rule in your own words — the AI reads every email and does it: label, sort, trash, unsubscribe. No filters, no regex, no conditions to wire up.
“What did I buy from Amazon last month?” It reads the actual emails and answers — by what they say, not just subject lines or keyword matches.
Connect your email, and Mocca sorts the rest — locally.
Sign in with an app password over IMAP. Guided setup for Gmail, iCloud, Yahoo and Fastmail.
The on-device AI reads your latest mail, separates the important from the noise, and applies your labels and rules.
Write rules in plain words, let Mocca auto-handle the junk, and ask questions across your whole inbox.
The AI features other clients offer run server-side — your mail is processed on their machines. Mocca's run on yours.
A private inbox with a built-in AI. Connect your email and you're set — no cloud, no account.
