Best WordPress AI Plugins
AI plugins bring content generation, chatbots, and image generation into the WordPress admin — most bring your own API key, then work directly in the editor. The category ranges from a deep, multi-provider toolkit to focused, budget-friendly writing assistants. Here's which fits which use case.

- 1Full reviewBest overall — deepest feature set
AI Engine
Free, Pro from $79 · LH 94 · 100,000+ installsThe most-featured AI plugin in the WordPress repository: content generation, chatbots, image generation, and admin-side tools, across OpenAI, Anthropic, Google Gemini, and local models — with MCP server endpoints for the emerging agent-to-WordPress path. Bring your own keys. The default choice if you want one AI plugin to cover everything.
- 2Full reviewBest all-in-one toolkit
AI Puffer
Free, Pro from $96 · LH 92 · 10,000+ installsAn independent plugin (rebranded from 'AI Power') that packs an unusually wide feature set into one install — content, chat, image generation, AI forms, and embeddings — across OpenAI, Anthropic, Google, and local models. The pick when you want the most capabilities in a single plugin and don't mind a dense, feature-heavy admin.
- 3Full reviewBest value for writers
AIKit
From $39 · LH 95 · 40,000+ installsA chat-style content generation experience that feels like using ChatGPT inside the WordPress editor, rather than the form-based UX of older plugins. It's sold as a one-time CodeCanyon license rather than a subscription — the cheapest option here — which, with its friendly interface, makes it a strong fit for individual writers and bloggers who don't need a deep feature surface.
- 4Full reviewListed for reference only Deprecated
Bertha AI
Free, Pro from $240 · LH 94 · 30,000+ installsIncluded because Bertha still shows up in older WordPress AI roundups, and you should know before you install it: the WordPress plugin is deprecated. The vendor's own site says it "no longer works with the latest version of WordPress" and points users to its Chrome extension instead. Its one distinctive idea — bundled inference, so there's no API key to wire up — now lives there rather than in the editor. If that's what you wanted, take the extension; if you want AI inside WordPress itself, take AI Engine or AI Puffer.

Frequently asked questions
- Do WordPress AI plugins need an OpenAI or Anthropic API key?
- Yes — all of the live options here do. AI Engine, AI Puffer, and AIKit each expect you to supply your own provider key (OpenAI, Anthropic, Google, and others depending on the plugin), so you pay the model provider directly for usage. Bertha AI used to be the exception because it bundled inference, but its WordPress plugin is deprecated, so bring-your-own-key is now the only realistic path inside WordPress itself.
- Which AI plugin is best for building a chatbot?
- AI Engine has the most mature chatbot feature set of these, including an advanced chatbot UI in Pro and multi-provider support. AI Puffer also offers chatbots if you want them bundled alongside its wider content, image, and forms toolkit.
- Are AI content plugins safe for SEO?
- The plugin itself is neutral — what matters is how you use it. AI-assisted drafts that you edit, fact-check, and add genuine value to are fine; bulk-published, unedited AI text is the risk. Treat these plugins as writing assistants, not autopilot.
Rankings are our editorial call, informed by the same reproducible data behind every detail page: Lighthouse scores are the median of five mobile runs on identical hosting, and open-CVE counts come from Patchstack and Wordfence Intelligence on every build. We take no payment for placement — the order reflects fit and merit, not sponsorship. Prices and install counts are vendor- and WordPress.org-reported and refresh on each build.
