Take control of your inbox: AI triage, attachment analysis and smart email tools for Gmail. All Powered by GPT 5.6 !

Most email tools help you write faster. Kerna handles the part before that: working out what needs answering, and finding the facts you need to answer it.

Kerna groups your inbox by what actually needs you, pulls structured data out of attachments and prepares the response — all inside Gmail™.

KNOW WHAT NEEDS ACTION FIRST

Every email can look urgent until you know what it needs.

Run Kerna’s Gmail inbox triage to organise messages around the work they create — customer requests, supplier follow-ups, quotes, documents to review and more. Start with categories relevant to your industry, then rename, remove or create your own in plain language.

Instead of reading from the top of the inbox down, see the work waiting for you and handle the right queue first.

ATTACHMENTS BECOME DATA, NOT JUST A SUMMARY

Invoices, purchase orders, delivery notes, contracts, reports and other documents often arrive as attachments — then someone has to read and retype their contents.

Name the fields once and Kerna reads every PDF, Word, Excel and CSV file in the thread against exactly those fields, so the columns line up every time. Export the result as an Excel or CSV file, with one row per document, ready to sort, filter and pass into the next system.

SET YOUR INDUSTRY ONCE

Your industry gives you a practical starting point in the three places Kerna does the heavy lifting. You are always editing a useful starting point rather than writing one from nothing.

* Triage starts with five categories that reflect how that industry works, rather than generic high, medium and low labels. Rename or replace them at any point.
* Attachment extraction includes five document types for each industry — 100 in total — with the fields those documents normally hold. Manufacturing includes purchase orders, supplier invoices, bills of materials, quality reports and packing lists. The purchase-order preset extracts order number, buyer, supplier, order date, required date, currency, net total, gross total, delivery address and Incoterms.
* Compose includes 200 email topics across the same industries, each asking for the details that topic needs. For example, the Legal settlement-proposal brief asks for the matter reference, opposing party, settlement amount, response deadline and key terms, so the draft comes back complete rather than generic.

Industries covered: Automotive, Construction, Consulting / Freelance, E-commerce, Education, Event Planning, Finance / Banking, General Business, Healthcare, Hospitality (Hotel/Restaurant), IT Services, Legal, Manufacturing, Marketing Agency, Media / Publishing, Non-Profit, Real Estate, Recruitment / HR, SaaS (Software) and Travel Agency. Every preset is editable, and you can use any industry set that fits your work.

THEN HANDLE THE REST

* Summarise long emails and threads into what changed, what was decided and what still needs action.
* Reply with a draft grounded in the thread, adjustable for tone, length and intent.
* Improve a draft you have already written, from a quick refinement to a fuller rewrite.
* Compose recurring types of email from guided topic prompts instead of a blank page.
* Translate emails and drafts across 45 languages.
* Extract dates, tasks and contacts from a message, then review them before saving to Google Calendar™, Google Tasks™ or Google Contacts™.

Kerna prepares the work; you check the output, decide what to do and send the reply yourself.

WHO GETS THE MOST OUT OF IT

Kerna suits people whose inbox behaves like a queue rather than a conversation: messages arrive from outside the company, carry documents or require a decision, and someone has to work out what each one needs before the real work starts.

* You are the address the company publishes. More arrives each day than you can read in order. Useful for office and practice managers, customer-service leads, and owners of small firms where everything lands in one place.
* Documents arrive attached and get typed out again. Useful for accounts payable, bookkeeping, procurement, logistics, site management and claims handling.
* You write the same handful of emails repeatedly. Useful for consultants, account managers, estate agents, and anyone sending proposals, quotes, updates and chasers.
* Your correspondence crosses languages. Useful for export sales, freight forwarding, and teams working with customers or suppliers in another country.

PRIVACY BUILT INTO THE MECHANISM

Personal data is redacted before message text reaches the AI model. Email content and attachments are covered by a zero-data-retention agreement with our model provider, so they are not stored by it or used to train models. Processing runs on Kerna’s infrastructure in the European Union, and only when you trigger an action. AI-generated text is clearly marked in the product.
