FAQ
This error comes from OpenAI’s API, not AI Engine. Set up billing limits in your OpenAI account. Caching plugins can sometimes store error responses, so clear your caches too.
AI Engine can be used by site owners, administrators, and visitors via chat widgets. To set query limits and prevent unlimited model runs, follow the Managing Limits guide.
AI models support many languages, but quality varies. There’s no definitive list since models are constantly updated. Test your language in the AI Playground.
MCP (Model Context Protocol) exposes WordPress tools to AI agents. Learn how to enable the SSE endpoint, choose which tools to expose, and secure them. You can manage posts, comments, users, media, and more.
You can’t completely block the model’s built-in knowledge, but you can use smart prompts and embeddings to steer conversations toward your content.

I was able to deliver smart value add chat bots to my first client’s site that it helped them reduce in office customer service calls by about 45 minutes a day using the AI Engine chat bot tool connect to GPT API. It was straightforward to use, even for a non technical person like myself. I started with a free AI Engine and as I created more sites it made sense to get the pro and I got the lifetime deal for the value.

|I never thought I’d get a response to my request, and certainly not so quickly! Even after several follow-up questions from me, the support team doesn’t seem to be tired of my inquiries and requests. That’s probably why AI Engine is one of the best—if not the best—AI plugin for WordPress. Thank you for your great work!

|This plugin is great for anyone with a bit of tech know-how. It prevents installing multiple plugins for various AI tasks. That’s always a win.

|AI Engine has been a genuinely pleasant surprise for me. I started using the plugin quite recently and quickly discovered that it offers far more depth and flexibility than I initially expected. Even the free version already provides a solid range of features that allow you to work with AI in a meaningful and practical way, without feeling limited right from the start. What I appreciate most is how clear and well-structured everything is. The plugin feels thoughtfully built. Things work smoothly, settings are easy to understand, and it invites you to explore without overwhelm. It makes it possible to create truly valuable AI assistants on your website, not just as a gimmick, but as something that can really support visitors and add depth to the user experience. Overall, AI Engine feels reliable, generous in what it offers, and created with care. It’s a powerful tool, both for experimenting and for building something that genuinely adds value, and it has definitely earned a lasting place in my toolkit.

|It’s amazing how much this plugin can do for your website. Even if you only use the ChatBot, it’s well worth upgrading to the Pro version. I had a slight hickup getting it going (my own fault) and yet got quick support over the weekend, even though I didn’t expect anything until the following Monday. I also use the Pro version of their Media Cleaner, another of their fantastic products.

I love the easy creation of excerpts, so much faster than me. And even though I almost always edit it, it still a huge time saver.The advisor is great as well, though I recommend to only enable it, when you need the advise. No reason to waste credits on a daily update, if you don’t use it on a daily basis.But I miss an easy alt text creator, with a button right below the alt text box to create or recreate. Could be linked to relevant SEO, but just a well written image description will get me most of the way.

A perfect Plugin and worth 5 Stars if – there would be a more in depth documentation of the functions it realy offers. Especially for developers the plugin offers nearly all functionality you need and many valuable hooks and filters. But not all of the available options are documented in a form where its easy to start from.For example there is an option to set own values for credits – the filter is mentioned in the docs, but not what values it expects as return. So one have to invest time to do a try and error testing or to review the source code to find out the options available. I realy love your plugin and your approach – its the perfect base for developing own solutions – like I do at the moment with a group billing and credit function – but a liitle bit more documentation would make live easier. EDIT: Forgot to say – if you make them aware of missing docs – they react quickly and add that. 🙂
