Your AI search & writing partner, built right into WordPress. Creating great content takes time. Paca AI puts powerful AI directly inside your post editor — no switching tabs, no copy-pasting, no leaving WordPress. In seconds, you can generate excerpts, write entire posts, proofread your content, and create stunning images. Everything happens right where you already work. Write More. Stress Less. Starting a new post is the hardest part. With Help Write, just describe what you want — “Write a blog post about the best hiking trails in Peru” — and Paca AI drafts it for you instantly. Structured headings, clean paragraphs, ready to edit. A blank page becomes a finished draft in seconds. Already have a post written? Hit Proof Read and Paca AI silently cleans up your spelling, grammar, and punctuation — without touching your formatting, links, or headings. What you wrote, just polished. Stop Writing Excerpts. Start Generating Them. Excerpts matter — for SEO, for social sharing, for your readers. But writing them is tedious. Create Excerpt reads your post and generates a sharp, on-brand summary in seconds. One click, done. You can even tell Paca AI exactly how you want your excerpts written, and it remembers every time. Beautiful Images Without a Designer Need a featured image? Create Image generates a professional, text-free illustration based on your post content — automatically uploaded to your media library and ready to publish. No Canva, no stock photos, no waiting. Just your content, turned into imagery that fits. AI That Learns Your Site The more Paca AI knows about your site, the better it performs. The AI Training feature quietly analyzes your recent posts in the background, building a picture of your topics, tone, and expertise. Every excerpt, image, and piece of generated content becomes more on-brand over time — without you doing a thing. A Search Experience Your Visitors Will Love Replace keyword search with something smarter. Paca AI Search understands the meaning behind your visitors’ questions, not just the words. Ask “What’s good for beginners?” and it finds relevant posts — even if none of them use that exact phrase. Drop the search block anywhere on your site and your content becomes genuinely discoverable. Visitors can also hit the Summarize button on any page and get an instant plain-English summary — great for long-form content, tutorials, or resource pages. Built to Be Customized Every site is different, and Paca AI is built with that in mind. The AI Search block drops into any page with a single click and works out of the box — but it doesn’t stop there. Customize the placeholder text, control how many results appear, adjust the search personality from a focused search tool to a conversational assistant, and write your own prompt to define exactly how answers are formatted. The Summary button is a simple shortcode you can place anywhere, with full control over the content selector, output location, summary length, and cooldown time. Prefer to build your own UI? Every feature is powered by standard WordPress AJAX endpoints, making it straightforward to create a fully custom experience while Paca AI handles all the AI logic behind the scenes. Designed to Stay Out of Your Way Paca AI lives in a clean metabox right inside the post editor — everything you need in one place. Generate excerpts, create images, proofread, get writing help, and control whether the post appears in AI Search, all without leaving the page. No cluttered toolbars, no modal takeovers, no learning curve. The settings are clean, the defaults work out of the box, and everything is one click away. Upgrade to Streaming — Answers That Feel Instant With a Paca AI license, your AI Search comes alive. Instead of waiting for a full answer to load, responses stream directly to your visitors word-by-word — just like ChatGPT. It feels dramatically faster, keeps visitors engaged, and makes your site feel genuinely modern. The license also unlocks priority response times and dedicated infrastructure, so your site never competes for resources. Paca AI works with OpenAI and Google Gemini.
