Kerna AI Email Assistant

Kerna turns a crowded Outlook inbox into a managed, prioritized workflow. Instead of scrolling through everything, you see what needs action first, get the context you need without opening every message, and move on. Kerna is built for people whose real work stalls behind email.

Take control of your inbox

• Inbox triage - Kerna reviews your inbox and sorts it by what actually needs you: high, medium, and low priority, so nothing important slips and nothing trivial steals your attention.
• Attachment intelligence - read, extract, and compare the contents of PDFs, Word, Excel, and CSV files without opening each one. Pull the numbers, terms, or details you need straight from the documents in a thread.
• Extract what matters - surface dates, tasks, and contacts from a message and turn them into calendar events, tasks, or contacts when you confirm.

Handle the rest in seconds

• Summarize long messages and threads down to the key points.
• Reply with AI-drafted responses you can tune for tone and intent.
• Compose new emails from a short instruction or a few bullet points.
• Translate across 45 languages - read and respond to anyone, in their language or yours.

Built for privacy. Kerna is operated from the European Union. Message content is processed only when you trigger an action, handled transiently to generate your result, and is not stored or used to train AI models. See our Privacy Policy.

Works across Outlook on the web, new and classic Outlook on Windows, and Outlook on Mac. Sign in with your Microsoft work, school, or personal account.
