Description
Planet ⑨ is an AI assistant plugin for WordPress that enhances your content creation and translation workflow with a smart, lightweight toolbar.
When you focus on a compatible text field, the floating toolbar activates in the bottom-right of your screen, giving you instant access to advanced AI features powered by OpenAI. The plugin integrates seamlessly with most themes and plugins.
Available AI assistants:
- Teller – AI-powered copywriting assistant
- Linus – AI translation assistant
More assistants are in development (e.g. image generation, code writing).
To use the plugin, you need an OpenAI API key. No data is stored or tracked — the plugin only sends content securely to OpenAI’s API for processing.
Current features (v2.15):
- Smart floating toolbar (active only in editable text fields)
- AI content generation based on your input or surrounding content
- Spelling and grammar improvement
- Automatic content structuring (headings, spacing, bullet points)
- Translation into multiple languages via dropdown selector
- Supports the GPT-4o model (fast, affordable, and highly capable)
- Toolbar is now draggable
- Fully privacy-friendly: no tracking, no local storage
Roadmap highlights:
- Additional AI assistants (image generation, SEO, code, etc.)
- Integration with Gutenberg, Elementor, and other page builders
- Toolbar customization options
- Improved compatibility with third-party fields

Frequently Asked Questions
Planet ⑨ adds a floating toolbar to your WordPress admin area that activates in supported text fields. From this toolbar, you can generate, improve, structure, or translate content using AI.
Once the plugin is installed, a floating toolbar will appear in the bottom-right corner of your screen. It activates only when you click inside a compatible text field.
The toolbar gives you direct access to AI tools. Each icon represents a different action:
- Pencil icon – Write your own prompt in the field (e.g., “Write a paragraph about…”). The AI will generate content based on your input.
- Star icon – Automatically generates content based on other filled-in fields on the page (ideal for titles, excerpts, etc.).
- ABC icon – Improves spelling and grammar without altering the original meaning.
- Structure icon – Enhances formatting and structure (e.g., headings, lists, spacing) without changing your message.
- Language selector – Instantly translates selected content into your chosen language.
You can click to apply the action to your current field.
Planet ⑨ uses OpenAI’s GPT models. By default, it uses GPT-4o.
Yes. The plugin does not track, store, or share your content. It only sends data temporarily to OpenAI for processing, and only when you trigger an action.
Planet ⑨ introduces AI agents (or “assistants”) that each focus on a specific task:
- Teller – Copywriting and content creation
- Linus – Translation
Future versions will include additional assistants for SEO, media, code, and more.
The toolbar is only active in compatible editable fields. If you’re using a custom page builder, it may not yet be fully supported. We are working on broader compatibility.
