Find the right spot in your 4D Write Pro document with AI
In 4D applications, large documents are commonplace: financial reports, internal guidelines, technical manuals… Searching for an exact keyword often isn’t enough. Scrolling through 30-page reports to find one paragraph is not only time-consuming but also error-prone. This is where AI can help.
The semantic approach based on vectors, introduced in 4D 20 R10, already makes it possible to find a relevant 4D Write Pro document even when different wordings are used (for example, “insert image” vs. “add picture”).
But what happens when a document spans multiple pages and covers various subtopics? Even if the entire text can be converted into a single vector, results are often better when we work at a finer scale. This is the idea behind chunking: splitting a document into coherent segments, each represented by its own vector.
This is precisely what allows us to go further: retrieving not only the right document, but also the exact passage that matches the search.
Intelligent 4D Write Pro document analysis with AI
In many business applications, users enter or receive unstructured text: customer feedback, internal notes, support tickets, reports, and more. This content represents valuable information, but it’s difficult to leverage without specific processing.
This is where artificial intelligence becomes a powerful tool: by automatically analyzing the written content of a 4D Write Pro document, it can extract useful metadata for understanding, sorting, or prioritizing.
In this demonstration, we’ve implemented a complete scenario of automatic analysis of 4D Write Pro documents using AI. From a simple text, the AI is capable of:
- Generating a concise title reflecting the content
- Identifying the tone (positive, negative, informative, urgent…)
- Suggesting classification tags
- Evaluating the document’s writing quality
The goal is clear: automatically enrich documents with usable metadata, without changing the user experience.
ORDA – Constructor and touched event – Detailed behaviour through a network
In this previous blog post, you discovered that ORDA entities can now have a constructor, allowing entity instantiation to follow a complete object-oriented approach.
And that’s not all — another blog post introduced the first ORDA data event in a full series: the touched event.
Want to know exactly WHEN and WHERE the constructor and the touched event are triggered while actions move back and forth between a client application and the server? This blogpost is for you.

AI Brings Magical Search to 4D Write Pro Documents
In many 4D business applications, documents are everything — technical notes, reports, manuals, internal guides. But when users can’t remember the exact wording, finding the right one becomes slow, frustrating, or worse — impossible.
With 4D 20 R10, semantic search powered by AI vectors changes that. Instead of matching keywords, you match meaning. Users get the right document, even if they search in different words or a different language. It’s a smarter way to surface the knowledge hidden in your documents — fast, accurate, and built for how people actually search.
Let’s consider a concrete example: a user wants to locate a technical note that explains how to insert an image into a 4D Write Pro document. However, they may not recall the precise phrase used in the document.
SHOWCASE: SMART EXPENSE REPORTING WITH AI
You know the pain of expense reporting — not for you, for your users. The receipts piling up, the manual entry, the typos that slip through. With 4D AIKit, that grind is gone. A simple upload turns a paper receipt or invoice into clean, structured JSON, ready for your database.
No more wasted time on totals, dates, or vendor names. Vision AI reads it, language models structure it, and 4D ties it straight into your app. From paper to database in seconds — and your users never feel the friction.
SHOWCASE: SMART COMMENT MODERATION WITH AI
Continuing our journey into intelligent features with 4D AIKit, let’s explore a highly relevant use case for any modern application: automated comment moderation. In a world where online conversations can happen in real-time, keeping your platform safe, respectful, and compliant is no longer optional, it’s essential. With AIKit, you can build powerful moderation tools directly into your application logic, without relying on external moderation services or human reviewers.
Tips & Tricks for your 4D Apps – April 2025 Edition
by Add Komoncharoensiri, Director of Technical Services at 4D Inc
Here we go with another set of tips and tricks.
The 4D Knowledge Base is a library of information about 4D technology where weekly tech tips and monthly tech notes are actively published. If you missed the last tips on the KB, that’s fine; here is a compilation from the past few weeks.
This blog post covers 15 tips:
Restrict data according to privileges or information saved in session storage
In modern application development, securing and finely managing data access are essential. Thanks to the restrict event in 4D, it is possible to dynamically filter the data accessible to a user based on their profile, privileges, and session-stored information.
This blog explains how to leverage this event, particularly in the context of an integration with 4D Qodly Pro, to ensure that only relevant data is exposed.
Designing an Interactive and Dynamic Menu Bar in Qodly application
In this week’s blog, we take a look at navigation. Navigation is a key element of any web application. A well-structured navigation system enables users to quickly find what they need and enhances their overall experience.
With 4D Qodly Pro, managing navigation is both simple and flexible. Using the Page Loader component, you can dynamically load pages based on user actions.
In this article, we will explore how to set up an efficient navigation bar using 4D Qodly Pro. We will use our Performance Review application as an example, which you can download from GitHub (link to be added). We will cover its design, interactions, and permission management to create a seamless experience tailored to each user role.
Customize your Qodly interfaces with CSS
In Qodly Studio, each widget can be styled directly using its properties. However, to maintain a consistent look throughout your application, and to easily apply global styles (such as font color, text size, or the appearance of selections), CSS is your best ally.
In this article, we’ll explore the basics of using CSS in Qodly Studio, with examples from the Performance Review application.
