Best AI Plugins for WordPress (2026): Free and Paid, Priced

Last updated: October 20, 2026. By Veer. Prices, version numbers, install counts and ratings checked October 20, 2026 on WordPress.org and each vendor’s pricing page. This is a researched buying guide built from official listings, documentation and security advisories; we haven’t run every plugin on a live site ourselves.

What is the best AI plugin for WordPress in 2026?

AI Engine is the best all-round AI plugin for WordPress, the official AI plugin is the best free starting point on WordPress 7.0+, and Jetpack AI is the easiest paid option if you don’t want to manage API keys. The right pick depends on the job, so here’s the short list with the numbers that matter.

WordPress.org shows ratings out of 100; we’ve converted them to five-star scores. Install counts are WordPress.org’s rounded figures.

Does WordPress have an official AI plugin?

Yes. It’s simply called AI, it’s published by WordPress.org, and it needs WordPress 7.0.3 or later. It’s free, but you supply your own AI provider key, and it only works in the block editor.

The plugin sits on top of the AI plumbing that shipped in WordPress 7.0 “Armstrong” in May 2026. Core now includes an AI Client that lets any plugin send prompts to a model, and a Settings > Connectors screen where you store provider keys once. WordPress doesn’t bundle a provider: you install a connector plugin for Anthropic, Google or OpenAI (local models through Ollama work too).

Version 1.4.0, released October 5, 2026, includes title, excerpt, slug and meta description suggestions, alt text generation, content summaries, translation of paragraph and heading blocks, image generation and editing, comment moderation with a new 0 to 1 “value score,” and editorial notes covering accessibility, readability, grammar and SEO. It also encrypts provider keys at rest with libsodium if you turn that feature on.

The catch: WordPress.org labels it experimental and recommends trying it on a staging site first. Features can change between releases, and there’s no Classic Editor support planned.

The best AI plugins for WordPress, one by one

AI Engine: best overall

AI Engine (version 3.8.6, updated October 17, 2026) does the most for free. The free plugin includes chatbots, a content and image generator, an editor copilot that rewrites, shortens and translates, a playground, REST and internal APIs, and an MCP server that lets ChatGPT, Claude or Claude Code read and edit your site. Its developer says the plugin adds no markup on AI usage: you pay OpenAI, Anthropic or Google directly.

AI Engine Pro adds AI forms, embeddings (a knowledge base built from your content and PDFs), function calling, realtime voice chatbots, advanced MCP tools for WooCommerce, database, theme and plugin management, and usage limits per user. It costs $69 a year for one site, $99 for five, or $179 for 20, with lifetime licenses from $499.

Who should skip it: anyone who doesn’t want to create an API key with an AI provider.

AI (official plugin): best free starter

If your site runs WordPress 7.0.3 or newer and you mostly want help inside the editor, start here. It’s free, it’s maintained in the open on GitHub, and features are opt-in, so nothing runs until you switch it on. Pair it with one connector plugin and you’ll have title ideas, excerpts and alt text in minutes.

Jetpack AI: best if you don’t want API keys

Jetpack AI from Automattic needs no provider account. The free tier gives you 20 requests for text, images, tables, titles and summaries. The paid plan lists at $119.40 a year (£95.40 in the UK), with the first year at $59.40 (£47.40), or $14.95 (£11.95) month to month, according to WordPress.com’s public price list. The paid plan also lets you connect Claude, ChatGPT or Claude Code to your site over MCP, with read and write permissions toggled separately and writes waiting for your confirmation.

“High request capacity” is subject to a fair-usage policy, so heavy bulk generation could hit limits.

AI Puffer: best low-cost hosted credits

AI Puffer (formerly AI Power) offers a chatbot, writer, AI forms, image generation and an MCP connection for ChatGPT and Claude. You can use your own keys or its hosted credits. The free plan includes 2,000 website actions and 25 AI credits a month; Pro is $9.99 a month for 10,000 actions and 1,000 credits, Plus is $14.99 and Pro Max is $29.99.

One setting to change on day one: AI Puffer says its “Trusted” connection level is the default for new MCP connections, which lets an assistant publish, change plugins and delete without asking. Switch to “Standard” so publishing and plugin changes need your approval.

GetGenie: best for SEO content

GetGenie combines keyword research, SERP competitor analysis, 40+ writing templates and rank tracking inside the editor. The free plan includes 2,500 AI words, 5 competitor analyses and 15 keyword analyses a month. The Starter plan lists at $10 a month for 20,000 words, with Writer at $19, Pro at $49 and Agency at $99; annual billing was discounted when we checked.

Uncanny Automator: best for AI automations

Uncanny Automator is a no-code automation builder (think Zapier inside WordPress) with an AI agent and page builder added. The free version includes some AI agent usage with no API key. Pro Basic costs $240 a year for one site (shown as $20 a month billed annually), Pro Plus $360 for 10 sites, and Pro Elite $480 for 50. If you’re weighing it against outside tools, see our n8n vs Zapier vs Make cost breakdown.

What is the best free AI plugin for WordPress?

The official AI plugin and AI Engine are the best free AI plugins for WordPress, because neither charges anything and both let you pay your AI provider directly. Choose the official plugin for editor helpers on WordPress 7.0+, and AI Engine if you also want a chatbot or an MCP connection.

“Free” still means paying for API usage unless you run a local model. If you’d rather not touch keys, Jetpack AI (20 requests), AI Puffer (25 credits a month) and GetGenie (2,500 words a month) have free allowances, but they’re small enough that you’ll know within a week whether you need to pay.

What is the best AI chatbot plugin for WordPress?

AI Engine is the best AI chatbot plugin for most WordPress sites, MxChat is the strongest free alternative for training a bot on your content, and WPBot suits sites that want a lifetime license. All three work with your own API keys.

If your bot needs to answer from your own pages, look for retrieval (often called embeddings or RAG). That’s a Pro feature in AI Engine but included in MxChat’s free plugin.

Which is the best AI SEO plugin for WordPress?

For AI-written SEO content, GetGenie does the most; if you already use an SEO plugin, its own AI add-on is usually the cheaper route. Here’s what each charges for AI features.

AIOSEO’s AI Writing Assistant is separate again: it needs a paid SEOBoost subscription. Rank Math’s site showed us prices in euros, so check its pricing page from your own region.

Are AI plugins for WordPress safe?

They’re as safe as you configure them: the main risks are leaked API keys and AI agents with more permissions than they need. Keep plugins updated, restrict who can use them, and require approval for anything an agent publishes or deletes.

The risk isn’t theoretical. AI Engine has patched two notable flaws this year: CVE-2026-8719 (CVSS 8.8), which let a logged-in Subscriber escalate to Administrator through the MCP OAuth path in version 3.4.9 and was fixed in 3.5.0, and CVE-2026-89141 (CVSS 6.5), which exposed private audio transcriptions when the Public API module was on, fixed in 3.7.8. Both are fixed in the current 3.8.6, but they show why open sign-ups plus AI plugins deserve care.

A short checklist:

• Update promptly. Enable auto-updates for AI plugins or check weekly.
• Turn off what you don’t use, such as public APIs, MCP servers or chatbot file uploads.
• Keep keys in one place. WordPress 7.0’s Connectors screen centralizes them, and the official AI plugin can encrypt them at rest.
• Set spending limits in your OpenAI, Anthropic or Google account so a runaway bot can’t run up a bill.
• Require approval for agent writes. Jetpack AI asks by default; AI Puffer doesn’t unless you switch to Standard.

Our AI agent security checklist covers this in more depth.

Do you need your own OpenAI or Anthropic API key?

For AI Engine, MxChat, WPBot and the official AI plugin, yes; for Jetpack AI, GetGenie and Uncanny Automator, no; AI Puffer lets you choose. API billing is pay-as-you-go and separate from a ChatGPT Plus or Claude Pro subscription.

If you’d rather drive WordPress from a Claude subscription you already pay for, you can connect it over MCP instead of buying a plugin plan. Our guide to connecting Claude to WordPress walks through it, and building a WordPress site with Claude shows what that looks like in practice.

Verdict: which AI plugin should you install?

Install AI Engine if you want one plugin that does chatbots, writing and MCP, and you’re fine creating an API key. Install the official AI plugin if you’re on WordPress 7.0+ and want light editor help at no cost beyond API usage. Pay for Jetpack AI if keys feel like a chore and you want Claude or ChatGPT access with confirmation built in. Add GetGenie only if SEO content is the job, and Uncanny Automator if automations are.

Whatever you pick, start with one plugin. Several AI plugins on one site means duplicate buttons in the editor, more keys to protect and more code to keep patched.

FAQ

What is the best AI plugin for WordPress?

AI Engine is the best all-round choice: it’s free, has 90,000+ active installs and a 4.9 rating, and covers chatbots, content generation and MCP. On WordPress 7.0+, the free official AI plugin is the simplest way to add editor helpers.

Is there a free AI plugin for WordPress?

Yes. The official AI plugin and AI Engine are free, though you pay your AI provider for usage. Jetpack AI (20 requests), AI Puffer (25 credits a month) and GetGenie (2,500 words a month) also have free tiers.

Does WordPress 7.0 have AI built in?

WordPress 7.0 added an AI Client and a Settings > Connectors screen to core, but no AI provider is bundled. You install a connector plugin for Anthropic, Google or OpenAI, plus the AI plugin for ready-made features.

What is the best AI chatbot plugin for WordPress?

AI Engine suits most sites. MxChat is a strong free alternative that can train on your sitemap, PDFs and videos, and WPBot offers lifetime licenses from $149.

Are WordPress AI plugins safe to use?

Generally yes, if you keep them updated, disable features you don’t use and require approval for agent changes. AI Engine fixed a high-severity privilege escalation flaw (CVE-2026-8719) in version 3.5.0 earlier this year.

Do AI plugins slow down WordPress?

Most AI work happens on the provider’s servers when you click a button, so editor tools add little load. Front-end chatbots add a script to every page, so check your speed scores after enabling one.
