An experimental web tool developed by the Automattic AI team. Simply type what you want to create in natural language, and it automatically generates Gutenberg custom blocks and block themes, previews them on WordPress Playground, and lets you download them as ZIP plugins. It was announced by CEO Matt Mullenweg at WordCamp US 2025 in September 2025, and has since added theme generation and a project showcase (community creation sharing and remixing).
Key Features
- Block & theme generation from natural language: Just type “create a block that does X” and it auto-generates code in a create-block compliant plugin structure. Themes (Full Site Editing compatible) can be created the same way
- Live preview on WordPress Playground: No local environment needed. Test blocks directly in the block editor within your browser
- ZIP download & share links: Download generated blocks/themes as ZIP files and install them on any WordPress site. Share preview links with team members or clients
- Iterative improvement with follow-up prompts: After initial generation, add functionality or adjust designs with additional instructions. Direct code editing is also available via the code view
- Project showcase: Browse, remix, and incorporate community-created blocks (Minesweeper, confetti effects, personality quizzes, etc.) into your own projects

Pros & Cons
✅ Pros
- Create custom blocks and themes using only natural language, with no coding experience required
- No local development environment setup needed—everything runs in the browser
- Excellent for rapid prototyping, making it easy to present ideas to clients and validate concepts
- Generated code follows the standard create-block structure, making it useful as a learning resource
⚠️ Cons
- As an experimental tool, generation results can be inconsistent and bugs may occur
- Complex parent-child structures using inner blocks are not yet supported
- Code may not function correctly for advanced operations like external API integration
- No prompt rollback feature, making it difficult to undo unintended changes
- Cannot customize admin screens or build blocks within blocks

Who It’s For
- Site owners who need “that extra bit of customization” that existing plugins can’t provide
- Agencies and freelancers who want to quickly present prototypes to clients
- Learners who want to study Gutenberg block development without setting up an environment from scratch
- Experienced WordPress developers who want AI to handle the initial draft so they can focus on refinement
Summary
Telex significantly lowers the barrier to WordPress block development as an experimental AI tool that generates blocks and themes from natural language. While powerful for prototyping and learning, production deployment of blocks involving complex logic or external API integration still requires traditional code review and testing.
