1.9New: an agent builds your workflows
Your data in. Finished documents out.
KBStudio is where you design invoices, statements, policies, payslips, labels and catalogues, and where they get produced. Point it at your data and it writes the PDFs, e-mails and print files, thousands at a time. It can run on a schedule, wait for someone's approval and deliver the results on its own. PDFs from other systems go through it too: read, split, edited, redacted and archived.
Every licence includes the starter bundle: 22 finished projects with 90 workflows you can open and run on day one.

- Every draft test-run and proved before you see it
- 200,000 pages in a single run
- Version history, promote to test and production
- Lineage from every page back to its record
- Approval in the app or from an e-mail link
- PAdES signatures and a password per recipient

02 / The product
Four parts that work as one program
You build a job in Designer. The other three parts take it from there.
The whole path in one picture
Data comes in at the top, finished documents leave at the bottom. Every box is a part of KBStudio and every line is a handover you can watch.

KBStudio
Designer
Where jobs get built. You connect data, prepare it, lay out the pages, check them in Page Proof and choose the outputs.
KBStudio
Automation
Runs a finished job without you. It can start on a schedule, when a file lands in a folder or on a REST call, and it runs as a Windows service.
KBStudio
Approval
Holds the job until the right people say yes. They can approve in the app or straight from the link in an e-mail, or send it back for changes.
KBStudio
Publisher
Delivers the files to a folder, an e-mail address, an HTTP endpoint or an SFTP server, retries when something fails and keeps a record of every delivery.
03 / How it works
The path every job takes
Each step below is a node on the workflow canvas. You can open any of them, test it on your sample data and see the result before you move on. Pick a step to see what it covers.
Data
Bring in whatever you have
- CSV, JSON, XML and Excel, one file or a whole folder
- SQL databases, Google Sheets and web APIs
- Existing PDF files and print spools, read page by page
- Run parameters and generated test data
Prepare
Get the records into shape
- Calculated fields, date and money formats, amounts in words
- Filter, sort, group with totals and join two sources
- Validation for required fields, VAT IDs, IBANs and totals, with bad records set aside
- Scripts for the rest: payroll, calendars, check digits
Design
Pages that follow the data
- Master pages, letterheads and envelope windows
- Tables that continue on the next page and repeat their header
- 28 chart types, 29 barcode types and pictures picked by the data
- Content that shows only when a condition is met, plus forms and a table of contents
Page logic
Put the pages in order
- Group pages into documents per customer, branch or region
- Drop blank pages, pad for duplex, add cover sheets
- Lay a layout over existing PDF pages, read and stamp values
- Counters for documents, pages and sheets
Ready for the press
- N-up, step and repeat, booklets and 16-page signatures
- Crop and registration marks, colour bars, slug lines
- Spot colours, CMYK conversion and PDF/X-4
- DataMatrix and OMR marks for the inserter
Output
All formats from one job
- PDF, PDF/A, PDF/UA, PDF/X and PostScript, per record, per group or as one print file
- E-mails with a personal text and the document attached
- JSON, XML, CSV and Excel, including UBL 2.1 e-invoices
- PAdES signatures and passwords per recipient
Check
See it before it goes out
- Page Proof shows the finished pages for each record
- Data Proof shows the records at any step
- Validation catches missing fields and broken bindings
- Messages tell you which node and which record
Automate
Let it run
- Start on a schedule, a new file in a folder or a REST call
- Conditions, HTTP requests and notifications between steps
- Runs as a Windows service with a job queue and retries
- Draft, promote and deploy, so production always runs a known version

04 / What it can do
The things people ask us about most
MCP
An agent builds it for you
Describe the job in a prompt and an AI agent builds the workflow over MCP, test-runs it on your records and proves it before you even look.
Job Builder
Give it a data file and answer ten short questions. You get a complete workflow with address block, table, channels and output, and you can change all of it afterwards.
Print production
Imposition, booklets, gang-up on SRA3, crop and registration marks, colour bars, spot colours and PDF/X-4.
PS
PostScript output
Print straight to a press or an older RIP. Import the PPD and the trays, media and device commands come into the job, with imposition, spot colours and transparency.
Runs by itself
Schedules, watched folders and REST calls start the job. A Windows service runs it, approvals hold it and Publisher delivers it.
Checked before it ships
Page Proof, Data Proof, validation and a full run log, so you know what went out and why.
Existing PDFs
Read values off the page, split spools per customer, OCR, redact, stamp Bates numbers. It handles 20,000-page files without loading them whole.
E-invoices
UBL 2.1 with the Croatian extension, Fiskalizacija 2.0 and FINA B2G, plus a readable PDF copy.
29
29 barcode types
QR, HUB3, DataMatrix, Aztec, MaxiCode, GS1-128, EAN, UPC, ITF-14, Code 128 and more.
Inserting
DataMatrix and OMR on every page or only on front sides, with sheet and set counters for the machine.
Signing and passwords
PAdES signatures with a visible signature box and a password per recipient, for example the employee's personal ID number.
Channels
Each recipient gets e-mail, paper or an archive copy, depending on consent and whether the address is valid.
WCAG
Accessible documents
Tagged PDF/UA with alt text, reading order and table headers. Checks for WCAG colour contrast, headings and language before export, and a conformance report after it.
Also in the box: tables across pages, table of contents and running heads, PDF forms, tagged PDF for accessibility, number and date formats, reusable components and styles, and project archives you can move to another computer.
05 / New
Tell an agent what you need, it builds the workflow
KBStudio speaks the Model Context Protocol, so an AI agent in any MCP client can build workflows for you. It drafts them, runs them on your own sample records, looks at the pages that came out, decodes the barcodes and writes a checks file anyone can run again.
What you write
Build a monthly statement for 40,000 customers from statements.json. Letterhead as the page background, the address in a DL window, a transaction table that continues across pages with its header repeated, Page X of Y, and a DataMatrix on every page for the inserter.
What comes back
- A finished workflow in your workspace, validated clean
- A test run on your own records, with the pages rendered and read back
- Barcodes decoded and checked against the values they should carry
- A checks file and a short README: what was built, what still needs a decision
Built for numbers. Dozens to hundreds of jobs in the time one used to take. We made 23 client projects with 96 workflows this way.
The agent drafts, you decide. It works only inside the workspace you name and only at the development stage. It cannot promote a workflow, deploy an automation, send e-mail or reach the production queue.
06 / Existing PDFs
Already have PDFs? KBStudio works on them too
Print spools from another system, scans, incoming invoices, a folder of statements. KBStudio reads them, splits them, redacts and stamps them, and writes them out again. Imported pages stay native PDF objects; nothing is turned into an image.
Read what is on the page
- Text from any area, with OCR for scanned pages
- Barcodes such as QR, Code 128 and DataMatrix
- Each page joined to your customer data by the value found on it
- Blank pages detected, ink coverage (TAC) measured
Rules with conditions
- Rules for selected pages only: first, last, odd, even or a range
- Any condition on the page, for example only landscape pages
- Child rules that run only when a value matches, such as INVOICE
- Every rule tested on the page in front of you before the run
Split and sort
- A new document whenever the customer number changes
- Split by bookmark, without reading any text
- A whole folder of PDFs, one record per file
- Covers, inserts, terms and return envelopes added per document
Edit the content
- Text, images or vector graphics removed from an area
- Objects moved by an exact distance
- An area covered with a box or clipped out of the print
- Each rule placed by corner or edge, so it fits A4, Letter and landscape pages
Redact and clean up
- Secure redaction: the content is removed, then checked at export
- Everything matching a pattern redacted, such as account numbers
- Forms and annotations flattened into the page
- Links, comments and stamps removed
Change the pages
- Scans made searchable with an invisible OCR text layer
- Pages rotated, scaled and cropped
- A page replaced with one from another PDF
- Very large files processed page by page, 20,000 pages and more
Stamp and number
- Barcodes and OMR marks for inserting machines
- Bates numbers, page counters, dates and watermarks
- Logos and signature images
- A whole layout laid over the existing pages
Look inside a PDF
- Properties, bookmarks, attachments, form fields and signatures as data
- Fonts that are not embedded and images below print resolution
- Damaged, locked or invalid files reported with error codes
- Invoice lines read from Factur-X, ZUGFeRD and XRechnung attachments
Before and after
Each pair is the page that went in and the page KBStudio wrote. The company and the data are invented.
BeforeAfter
A statement after anonymisation: the account holder block, IBANs, card numbers and OIBs are removed from the file, not just covered.
Then sign them (PAdES), protect them with a password per recipient and deliver them like any other output.
07 / For production
Projects, versions, tenants and the systems around you
A document job in production needs more than a nice layout. It needs a place to live, a history, separation between customers and a way to talk to your other systems.
Workspaces and projects
Work is organised into workspaces and projects. A project holds its workflows, layouts, data samples, fonts and pictures, and you can pack it into an archive and open it on another computer.
- One workspace per team or customer, many projects inside
- Workflow catalogue with status, version and owner
- Shared components and styles reused across projects
- Project archives that carry every resource with them
Versions and promotion
Every workflow and automation has a history. You commit a version with a note, compare and restore older ones, and promote a tested version to production when it is ready.
- Commit with a message, see who changed what and when
- Draft, test and production stages
- Production always runs a known, promoted version
- Roll back to an earlier version in one step
Multi-tenant
One installation can serve several customers or departments. Each tenant has its own users, queues, approvals and deliveries, and nobody sees another tenant's jobs.
- Tenants with their own users and roles
- Separate job queues and delivery logs
- Approvals routed to the right people per tenant
- Administration from the Operations console
Integrations
KBStudio reads from and writes to the systems you already run, so documents start from live data and end up where they are needed.
- REST API to start jobs and pass parameters
- HTTP requests, OAuth2 and mTLS for your ERP and web services
- SFTP in and out, SMTP for e-mail, SOAP for FINA
- SQL databases, Google Sheets, watched folders and DMS feeds
