Exonis: One platform, multiple AI tools.
Exonis brings AI into your vjoon K4 workflow. Exonis Proof corrects every article and flags anything that needs editorial review; Exonis Parse turns every PDF ever published into a searchable archive, and Exonis Translate creates new language versions even as the original continues to be processed for print. All without ever leaving K4.
In a magazine newsroom, the final hours before the deadline are spent on proofreading – a process that readers don’t notice if it’s done correctly. Typos and punctuation, dates written exactly as the magazine specifies. A person with blue eyes in the introduction and brown eyes in the body text. A caption that no longer matches the article after the final revision. Meanwhile, articles remain stored somewhere as PDFs for years, and every new language version means that texts have to be tedious copied back and forth and translated by someone.
Exonis handles the repetitive aspects of this work without disrupting the workflow that editors are already familiar with. It is an AI platform designed for content management across all industries and connects directly to vjoon K4 via three independent modules:
- Exonis Proof: AI-powered proofreading within the K4 workflow, featuring automatic corrections and annotations for the editor.
- Exonis Translate: Automatic translation of articles in K4 for new language editions that are published simultaneously with the original print edition.
- Exonis Parse (for magazines and newspapers): Automatic extraction of every article from editorial PDFs into a searchable, classified archive.
Each module solves a specific problem and offers value on its own, so publishers can start with one and add the others as needed.
Why generic AI is not enough
General-purpose text processing tools treat text as a single long string of characters. They do not recognize that a headline, an introductory sentence, a caption, and the body text are distinct elements governed by different rules. They often edit sections of text where an editor merely wants to add a marker, and they are unaware of a magazine's particular style guidelines.
Exonis was designed the other way round: it starts from the structure of the editorial page and the rules of each magazine.
Exonis Proof: AI proofreading within the K4 workflow
At a defined step in the K4 workflow, K4 XTD (External Task Dispatcher) automatically transfers the article to Exonis Proof. Exonis Proof reviews it and returns it to K4 in its original structure, with the workflow metadata intact. Nobody copies text out of the system and nobody pastes it back in again.
The review process consists of five steps. In the first step, obvious corrections are made directly to the text: typos, spelling, punctuation, spacing, grammatical consistency, units of measurement, and abbreviations. In the other four steps, the text is not altered. Here, notes are added for the editor: deviations from the magazine’s style, unclear or ambiguous passages, contradictions within the article, and facts that do not match public sources.
Playing time: 1:00 min.
How Exonis Proof works within the K4 workflow
What the editor sees
The result opens right where the editor is already working: in Adobe InCopy, Adobe InDesign, and the K4 Article Editor. Corrections are already included in the text. Anything that requires review is displayed as a note, each with a specific severity level: Note, Warning, Critical. Each note includes a quote from the relevant passage and a suggested course of action; the final decision always rests with the editorial team.
Brand style, magazine by magazine
Every magazine has its own conventions: quotation marks, date and number formats, the way ages are written, and which terms are acceptable and which are not. Exonis applies these rules individually to each magazine brand. Even for recurring sections with labeled blocks – such as a horoscope or a recipe page – the order of the labels is checked.
What’s changing: Proofreading is becoming an automated task within the K4 workflow, and editors will now only review the comments that require their attention.
Exonis Proof is already being used in production at a major Italian publisher, where it has cut proofreading costs by 70%.
Exonis Translate: same Layout, new language
Exonis Translate creates translated digital editions within a dedicated K4 workflow, which are completed at the same time as the original print edition. As soon as an article is approved, it is forwarded to Exonis via K4 XTD through a status change. Exonis translates it using a shared glossary for each publication, and the translated text is fed back into the original layout, where InDesign Server generates the PDF.
The entire process takes place within K4 from start to finish. The editorial team is only involved for a brief final review or approval, if necessary. Layout adjustments required for longer translated texts can be made before the PDF file is created.
Here, the translation goes beyond simply copying text into an external tool: styles and layout are preserved, terminology remains consistent from issue to issue, and the data structure is prepared for additional languages and issues.
How Exonis Translate works within the K4 workflow and vjoon seven DAM
What’s changing: Content creation in a new language is fully automated, which significantly reduces the time required to produce a new issue. At the same time, Exonis provides vjoon seven with all content in a neutral format, both in the original language and in the new language.
Exonis Parse: Every article ever published, ready for repurposing
Exonis Parse extracts neutral, structured text from editorial PDF files – both from the latest issues and from archived articles published in previous years. The system recognizes where each article starts and ends – even across facing pages – and separates the headline, lead, caption, and body text from one another.
The result is a content database containing every article a publisher has ever published. On the web, it feeds areas with paywall content. As an archive, every article is categorized and searchable, allowing editors to see which topics have already been covered and decide which new articles to produce. Combined with generative AI, the archive helps editors write new articles in the same style.
How Exonis Parse turns PDF files into a content database
What’s changing: Extracting and structuring articles from PDF files is now fully automated, requiring no human intervention and taking significantly less time per issue. Each new issue is automatically added to a searchable, classified archive, along with articles from previous years.
Exonis AI: One platform, built to grow.
As the heart of the platform, Exonis Flow manages how content flows into and out of Exonis. It connects Exonis to the publisher’s systems via APIs, a web interface, or file-based workflows—such as cloud storage buckets—without altering the existing infrastructure. Each workflow is tailored to the publisher’s specific processes—from capture and processing to delivery. Flow automatically routes each document to the correct module and handles any errors that arise, ensuring that the entire process runs unattended.
Exonis does not require editors to switch tools. For vjoon K4, the integration is handled via K4 XTD: Articles are automatically transferred when they reach a specific workflow status and return to K4 in their original structure with intact workflow metadata. For other systems, Exonis provides REST APIs with asynchronous processing and webhook notifications, enabling server-to-server integration with any editorial platform.
Exonis is a modular platform, not a closed-off product. New features can be added as a publisher’s needs evolve, and integrations can be implemented for any workflow and channel. All modules use the same infrastructure and the same APIs; once Exonis is integrated, every new feature is available without having to start from scratch. Publishers can start with a single module and expand Exonis step by step – from proofreading and archiving to translation and beyond.
Your content remains yours
The content is processed on an infrastructure where data is stored separately by customer. It is never shared with third parties, never used to train AI models, and is deleted after delivery. Through a web portal, customers can manage access keys, activate modules for individual teams or titles, set spending limits, and monitor usage. Pricing is usage-based: Publishers pay only for what they actually process, with no fixed user licenses. For the European market, Exonis complies with the requirements of the AI Act.
Exonis is an AI platform for content management across all industries that connects directly to K4 through its modules “Exonis Proof”, “Exonis Parse”, and “Exonis Translate”. The platform is divided into modules that publishers can implement individually. It analyzes the individual components of an article, applies each magazine’s specific style guidelines, and leaves the final decision to the editorial team.
Exonis is already being used in production at a major Italian publisher. Exonis Proof has already cuts proofreading costs there by 70%.
