How it works
From a full inbox to a sent reply, without leaving Gmail or Outlook
10 stops. The first is installing an add-in that takes a minute, the last is you pressing send. Everything between happens in the inbox you already have.
- 1
Triage
Install
Kerna appears in the sidebar of the Gmail or Outlook you already use. Your mailbox does not move and nothing is imported.
- 2
Run triage
One action. Kerna reads what is in the inbox and sorts it against the taxonomy you chose, either one of twenty industry sets or categories you wrote yourself.
- 3
See what matters
The inbox comes back grouped, so the five messages that need you today are separated from the two hundred that do not.
- 4
Translate, Summarize and Extract
Translate
A supplier writes in a language you do not read. Kerna works across 45 languages, in both directions, tuned per language rather than passed through a generic translator. This comes first for a reason: you cannot summarise what you cannot read.
- 5
Summarise the thread
Forty replies deep and just added to it. Kerna gives you the decision, the open question and who is waiting on whom.
- 6
Pull data from the email
The order number, the date, the amount, the address, all sitting in the body of the message. Kerna reads them out as fields rather than leaving you to scroll and copy.
- 7
Tone and Reply
Set tone and intent
Before anything is written, not after. Seven tones and eight intents: decline firmly, agree with a condition, ask for more time, chase an invoice. Choosing first is what stops you rewriting a generic draft into the register you actually needed.
- 8
Generate the reply
Kerna writes it from the thread and from what you just chose, so the reply already knows what was asked, what has been agreed, and how you want to sound. It lands in the normal reply window, so you can change anything in it before it goes.
- 9
Translate it back
You read the original in your language at stop four. Now the reply goes the other way, into the language your correspondent actually uses, so they get it in theirs and you never left yours.
- 10
You press send
Kerna never sends anything. The draft sits in your window until you read it and send it yourself, which is the whole point for work that gets audited.
Attachment extraction
The invoice is attached. The numbers should not have to be typed twice.
This one is not on the map, because it does not need anything that came before it. Open any message with a PDF, DOC or XLS on it, point Kerna at the attachment, and the fields you asked for go straight into a spreadsheet. A hundred presets across twenty industries name those fields before you start, and you can add your own on top.

- 1
Open the message
The one with the PDF, DOC or XLS on it. Kerna is already in the sidebar, so the file does not get uploaded anywhere to be read.
- 2
Pick the preset
A hundred of them, twenty industries by five document types. The fields are named before you start, which is the difference between a tool you use today and one you meant to configure.
- 3
Add your own fields
Presets cover the common case, not your case. Add the internal reference your finance team keys on and Kerna looks for that too.
- 4
Export it
A Google Sheet from Gmail, an Excel file from Outlook. A new one every time, so nothing you already have is appended to or overwritten.
In Gmail
One attachment at a time, exported to a Google Sheet. A new sheet every time, so nothing you already have is appended to or overwritten.
In Outlook
Every attachment on the message in one pass, or just one if that is all you need, exported to an Excel file. A new file every time.
Compose Assistant
Nothing to reply to, because you are the one starting it.
The other half of the writing problem is the email nobody sent you. Three ways in, one finished draft, and a translation pass at the end if the person reading it does not share your language.

Choose who it goes to
Type the addresses, pull them from your contacts in Gmail or Outlook, or import them from Excel if you are in Outlook.
- 2
Choose where the message comes from
Three routes, and they do different jobs. A prompt you saved earlier and use again. One of 200 topics, ten for each of twenty industries. Or a prompt you write for this message alone and do not keep.
- 3
Give it the specifics
The names, the dates, the amounts. A short form asks for what the message cannot be written without, rather than leaving you to remember what you forgot to mention.
- 4
Set the tone
The same control you get on a reply. How the message should land is a decision, not something to be discovered by rewriting it four times.
- 5
Generate it in the language you think in
A complete draft with the subject line already written. Write it in the language you can actually judge, because you cannot check a draft you cannot read.
- 6
Then translate it into theirs
A second pass, into any of the 45 languages. You checked the message when it was still in your own language, and the recipient gets it in the one they use.
- 7
It lands in your compose window
And stops there, exactly as a reply does. Nothing is stored, and nothing goes anywhere until you press send.
The things people tell us before they install it
Every one of these is a sentence someone actually said. The answer underneath is what Kerna does about it, not the name of a feature.
“I open the same email three times before I actually deal with it.”
Because it arrives mixed in with everything else and you keep deferring it. Triage puts it in a group with the other things like it, so you deal with a category once instead of the same message three times.
Stop 2 on the map
“Half my morning goes on deciding what to read first, before I have replied to anything.”
One action sorts the inbox against categories you chose. The deciding is done in a few seconds and you start the day on the five that matter.
Stop 2 on the map
“Somebody forwards me a forty-message thread and writes "thoughts?"”
A summary that tells you what was decided, what is still open and who is waiting on whom, so you can answer without scrolling to the bottom and guessing.
Stop 5 on the map
“I need to reply to a client in German and my German is school-level.”
Read it in your language, write the reply in your language, send it in theirs. 45 languages, tuned individually rather than run through a generic translator, so it does not read like a machine wrote it.
Stop 4 on the map
“I am retyping numbers off a PDF invoice into a spreadsheet. Again.”
Kerna pulls the named fields straight out of the attachment and exports them to Sheets and Docs from Gmail, or Excel and CSV from Outlook. Twenty industries, five document types, no copying and pasting. It is a feature in its own right rather than a step in the daily loop, so it is set out separately further down this page. If the numbers are in the message rather than attached to it, stop six does the same job on the body text.
“I have rewritten this one sentence five times so it does not come across as rude.”
Pick the tone and the intent instead of wrestling the wording. Declining firmly, agreeing with a condition and asking for more time are different jobs, and Kerna treats them as different jobs.
Stop 7 on the map
“The awkward email sits there all day and I still have not sent it by six.”
Most of the delay is the blank window. A generated reply on the screen turns a task you are avoiding into an edit you can finish in a minute, and it does not send until you do.
Stop 8 on the map
“Someone asked where our email actually goes when we use an AI tool, and I did not have an answer.”
Here is the answer: Cloud Run in europe-west1, Firestore in europe-central2, model processing contracted with OpenAI Ireland Limited under a signed zero data retention agreement, and personal data removed before content reaches the model.
