Write less. Do more.

Kerna is the AI productivity assistant for Gmail™ that turns hours of inbox work into a few clicks — triage, summarizing, drafting, and replying, right where you already work. No new tabs, no copy-pasting, no switching apps.

Professionals spend over a quarter of the workday on email. Kerna gives that time back — and handles any of 45 languages while it does.

📥 START WITH WHAT MATTERS
- Inbox triage: Kerna scans incoming mail and surfaces what's urgent, what needs a reply, and what can wait — so you work the messages that matter first [NEW]
- Stop scrolling a full inbox trying to decide where to begin

⚡ CATCH UP IN SECONDS
- Summarize any email — brief, standard, or detailed
- Summarize an entire thread with one click — what was said, what was decided, what's still open
- Summarize attachments — pull the key points from PDFs and documents without opening a single file [NEW]
- Full translation in 45 languages (not just summaries), with automatic language detection — read any email as if it arrived in your own language

↩️ REPLY IN ONE CLICK
- Generate a reply with 7 tones: Formal, Casual, Friendly, Direct, Enthusiastic, Diplomatic, Empathetic
- Pick from 8 intents: Agree, Decline, Ask for Clarification, Provide Info, Follow Up, Thank, Apologize, Negotiate
- Replies come back in the email's original language, automatically
- Creates a threaded Gmail™ draft you review before sending — you always control the final send
- Save custom reply prompts for the situations you handle again and again

✍️ COMPOSE WITHOUT THE BLANK PAGE
- Draft a professional email from a template or a one-line instruction — pick department, topic, and details
- Quick Improve for a fast grammar fix, Advanced Improve for a full rewrite
- Translate any draft into any language before you send
- Import recipients from Google Contacts™

🗂️ CAPTURE DETAILS — WITHOUT RETYPING
- Extract contacts automatically (name, email, phone, role)
- Extract calendar events with conflict detection — Kerna warns you before you accept a meeting that clashes with your schedule
- Extract action items as clear, ready-to-do tasks
- Smart Focus: define your own extraction fields (e.g. "ticket number", "contract value", "deadline")
- Save anything Kerna finds straight to Google Tasks™ or Google Calendar™ — no copy-pasting between apps
