About this plugin
Cubix AI Article Generator turns your WordPress dashboard into a complete AI writing studio — without a monthly subscription.
Connect a free API key (Groq, Google Gemini, OpenRouter, and Mistral all offer genuinely free tiers with a two-minute signup and no credit card) and start generating titles, full articles, excerpts, outlines, FAQs, SEO keywords, and more — directly where you write.
✍️ Twelve writing tasks in your editor
A beautifully designed panel appears right in the post editor:
- Write — full articles, post titles, excerpts & meta descriptions, structured outlines, FAQ sections.
- Refine — rewrite & improve, expand & enrich, summarise, or translate your existing draft. One click sends your current post as context.
- Optimise — SEO keyword suggestions, tag ideas, and conversion-focused call-to-action paragraphs.
Every result shows a live word count with Regenerate, Expand, Copy, and one-click Use it — which inserts content into the Block Editor or Classic Editor, sets titles, or fills the excerpt field automatically.
💬 AI Studio — a real chat workspace
A full multi-conversation chat experience inside wp-admin:
- Start unlimited new chats; each is titled automatically from your first message.
- Conversation history sidebar with one-click switching.
- Delete any single chat, or everything with one button.
- Conversations are private per user and auto-delete after 10 days.
- Switch AI engines mid-conversation.
🔌 Seven AI engines — including truly free tiers
- Groq — very fast Llama, Qwen, and GPT-OSS models. Generous free tier, no credit card.
- Google Gemini — AI Studio keys include free usage.
- OpenRouter — hundreds of models with one key; the smart “Auto — free models” option finds whatever is free right now, automatically.
- Mistral AI — free experiment tier.
- OpenAI, Anthropic Claude, DeepSeek — premium pay-as-you-go quality when you want it.
Every engine card has a direct “Get a key” link and a one-click connection test. Keys are encrypted at rest using your site’s own authentication salts and are never included in settings exports.
🎛️ Built for real teams
- Choose which post types show the AI panel.
- Set the minimum role allowed to use AI — from Contributors to Administrators only.
- Usage dashboard: total generations, words written, monthly activity, per-engine breakdown.
- Recent-generations history in the editor to re-run earlier prompts.
- Fully editable prompt library — ship your own starter prompts to your writers.
- Default tone (9 options), length presets, output language, and creativity control.
- Move a finished configuration between sites with JSON export and import — API keys are never included, so each site keeps its own.
🔒 Privacy first
No accounts. No middleman servers. No tracking.
Your prompts go directly from your server to the AI provider you chose — nothing passes through us, and site visitors never trigger any request. See the External Services section for exactly what is sent where.
🧑💻 Developer friendly
Clean, object-oriented, fully prefixed code with filters for everything: cxai_providers, cxai_modes, cxai_prompt_templates, cxai_system_prompt, cxai_user_prompt, cxai_generated_content, and cxai_create_provider to register custom engines.
External Services
This plugin connects to third-party AI APIs to generate content, power the AI Studio chat, and test API keys. No data is transmitted anywhere until a logged-in user presses Generate, Test connection, or sends a chat message. When they do, the prompt text — and the current post content, only when the context option is used — is sent to the single engine selected for that request:
