imagine being able create a custom WordPress block simply by describing your idea… without writing a single line of code.
This is precisely the promise of Telex on WordPress, the artificial intelligence tool developed by Automattic for generate Gutenberg blocks from a simple prompt.
But does this solution truly deliver on its promises? Can it accelerate your workflow or create custom features for your site?
In this post, Discover how Telex works, its advantages and limitations, and concrete examples of its use. as well as best practices for effectively integrating it into your WordPress projects.
What is Telex on WordPress and how does this tool work?
Telex is a WordPress block creation tool powered by AI, based on a natural language text prompt that you provide.
Created by Automattic, the company behind WordPress.com, Telex was launched at WordCamp US in late August 2025.
Described as a "V0 or Lovable, but specifically for WordPress" According to Matt Mullenweg, CEO of Automattic, Telex's operating method can be broken down into 4 stages:
- Describe in French the result you wish to achieve.. For example : "I want a block to integrate a reading progress bar in minutes on my WordPress articles.".
- Telex WordPress converts your natural instructions into working code (React/PHP code).
- You preview the result obtained, which you can amend by providing further modification instructions to the AI.
- You are downloading an extension in .zip format (which contains the block.json, CSS and JS files necessary for its execution). It is ready to be installed on your WordPress site or on the Playground testing environment (a tool to deploy WordPress in your browser).
Telex acts as an assistant or intelligent "sidekick" for your projects. It generates a clean first draft that adheres to WordPress coding standards.
At the time of publication, the tool is still described as"experimental"In this regard, Automattic indicates that its "Features may evolve and results may vary as we refine the AI technology.".
What are the advantages and limitations of using Telex for WordPress users?
While the enthusiasm is genuine, it is important to weigh the pros and cons if you wish to use this tool wisely.
Advantages of Telex on WordPress
Available for several months, Telex is evolving and maturing week by week. This AI tool boasts several advantages that could be of interest to you if you wish to use it:
- It is free and unlimitedIn this regard, Automattic does specify that it may suspend or limit long sessions during periods of high traffic.
- The creation process is very fastYour prompt will transform into a functional block in one to two minutes.
- No prior knowledge or experience in coding is required.. "Telex is designed for everyone, from complete beginners to experienced developers."Automattic explains. Non-technical users gain complete autonomy. There's no longer any need to call in a developer for every small, specific adjustment to your site.
- You can share your creations with the people of your choice to facilitate collaboration.
- Learning happens through concrete examples.By analyzing the generated code, novices grasp the logic of modern Gutenberg blocks. It's a pedagogical gateway to development.
- The tool complies with official WordPress standardsThe code is based on WordPress Components. This ensures seamless visual integration into your administration interface.
- All blocks generated by Automattic's Telex are private by default.They only become public when you click the "Share" button.
Limitations of the tool
As you can see, the advantages are numerous. But to be completely thorough, there are also several limitations to keep in mind before using this tool.
First, Telex on WordPress is still experimental, as mentioned above. This means you may encounter a few minor bugs or technical issues during useand that the results may vary, as specified by Automattic.
Next, you are directly depending on the accuracy of your prompt with Telex from Automattic. A vague instruction will inevitably produce a unit struggling to meet your expectations.
Furthermore, in terms of design, Managing nested structures remains a weak pointArtificial intelligence still struggles with very complex layouts. Sophisticated interactions often require manual intervention.
Furthermore, fine aesthetic customization requires manual CSS tweaksThe AI delivers a standard style that you will need to adjust according to your graphic charter.
If you want to delve deeper into this topic, I recommend watching this informative YouTube video:
A systematic human review remains essential before any deployment. The code, which you can view and edit, may contain errors. Never deploy to production without rigorous verification. As Automattic explains, "AI is powerful but not perfect. Always remember to back up your important work and test your blocks before using them in production."
Automattic's Telex, for whom?
Telex's versatility raises a question: who really benefits from integrating the tool into their daily workflow?
If we trust what Automattic claims, Telex is for everyone because it requires no programming experience.
On its official website, WordPress.com specifically distinguishes four user groups :
- Site owners (bloggers, designers, entrepreneurs, etc.). If you have, for example, a shop WooCommerceYou can create a small shipping cost calculator or a comparison table in seconds.
- WordPress agencies and freelancersThis can save time and increase efficiency. For example, you can prototype functional models directly in front of your client. This accelerates concept validation before final development, avoiding unnecessary back-and-forth.
- Experienced developers They can use it to eliminate repetitive tasks and speed up their workflow.
- Beginner developerswhich can add interactive elements without touching a line of code.
Finally, let's not forget also WordPress trainersfor whom Telex is an excellent teaching tool to show how a block is constructed.
But also anyone curious about the evolution of AIIt's a gateway to the future of simplified web creation.
How to integrate and use Telex on your WordPress site?
Moving from theory to practice is surprisingly simple, provided you follow a few key steps.
Prerequisites and configuration
Before you start creating your next block, there are several prerequisites:
- A WordPress.com account is required to use Automattic's Telex.
- Your WordPress installation must be running at least WordPress 5.0 to be able to support blocks created with the WP editor (Gutenberg).
- Have a web browser (Chrome, Firefox, Opera, etc.) since the tool works on your browser.
Creating WordPress blocks with Automattic's Telex tool
Is everything good for you? To start the creative process, go to... the official Telex WordPress website.
Click on the "Login" button in the top right corner of the page., to log in to WordPress.com or create an account.
Follow the on-screen instructions to achieve this. Once you have done so, you will be taken to the creation interface.
The rest is very simple. Describe your final idea using the text prompt of your choice.
Automattic offers the following advice for obtaining an accurate and efficient prompt:
- Be specific about both the features and the appearanceThe more details you provide about the layout, colors, and features, the better the results will be.
- Include details about what users will see on the public side and on how content creators will use the block in the editor.
- Send screenshots or mock-ups to help Telex understand exactly what you are looking for.
- Start with a basic version of your block, then refine it with additional instructions.
To help you, you can also rely on your favorite LLM (Claude, ChatGPT, Gemini, etc.). Ask it to create a custom prompt for you by describing the final block you want to achieve. And incorporate the tips above from Automattic for even more precise results.
Enter your prompt in the designated box (Telex understands French). For our example, we're asking Telex WordPress to generate a Gutenberg block that displays the estimated reading time of an article along with a reading progress bar.
After one to two minutes, you get an initial rendering:
This is a first draft that you can (and should) improve through iteration.Use follow-up prompts to refine features, design, etc. To do this, add new instructions in the bottom right corner of the screen:
If you have a good foundation in coding, you can also directly modify the code of the block generated by Telex by entering the "Code" menu:
Using your WordPress blocks
When your block meets your initial expectations, all you have to do is install it on your showcase site or WordPress store.
You will receive a zip file of your extension. If needed, you can also share your project with others via a unique link.
Always test your Telex plugin on a test site (local, staging) before deploying it to production. And always back up your online site (files + database) before adding anything. For this, you can, for example, use the extension WP Umbrella.

Troubleshooting and solutions to problems encountered with the Automattic Telex tool
Despite its fluidity, the experiment can sometimes encounter some frustrating technical obstacles.
Telex's AI sometimes stops during code generationTry to simplify your initial request. An overly complex prompt will eventually confuse the algorithm.
Display issues may occur in Playground. Check your internet connection or clear your cache. The tool runs via WebAssembly, so it is resource-intensive.
Is your WordPress Telex block not displaying? Check that WordPress is up to date, as the tool uses recent features.
Regarding the style of your block, Automattic recommends that, in case of problems, you...add a follow-up prompt specifying the desired colours, fonts or layout preferences.
Conflicts with other extensions can also paralyze the system. Temporarily disable your caching modules. These tools sometimes disrupt the final rendering of the generated block.
Finally if your block is not working properly, that's what you can try to do, according to Automattic. "Try a follow-up prompt describing the specific problem. You can also ask Telex to 'fix the error' and explain what isn't working as expected."
Future prospects and impact of AI on the WordPress ecosystem
Telex is just the tip of the iceberg, which sees Automattic investing more and more in AI (both in terms of time and financial investment).
The North American firm has stepped up its efforts in artificial intelligence for several months now, with, for example the establishment of a dedicated team to work on the integration of AI in the core of WordPress.
Many advances have already taken place, such as the upcoming introduction of "Connectors" with the release of WordPress 7.0 (early April 2026), which is an option to connect your favorite LLM (Claude, OpenAI, Anthropic, Gemini) to your WordPress dashboard.
Regarding Telex specifically, very little information has been released about its future. Automattic simply states that The product remains experimental. This suggests that an "official" version should be released within a few weeks. Could it even be integrated directly into the WordPress core? Only time will tell.
Meanwhile, the project team "Experience every day", is it specified.
Our final verdict on Telex
In our opinion, Telex, the AI tool developed by Automattic to create WordPress blocks, is a promising initiative to simplify development in the Gutenberg ecosystem.
It allows you to quickly generate functional blocks from a simple prompt, which can save you valuable time prototyping features or testing ideas.
In practice, Telex proves effective in producing a structured codebase that conforms to modern WordPress standards.
However, like many AI tools, It still needs improvement in the details. : code optimization, UX adjustments, fine-tuning of performance or integration into an existing project.
In other words, it's an excellent starting point, but does not yet replace the expertise of a WordPress developer to finalize a clean, robust and perfectly integrated block.
