Arguto
The WordPress chat that gets things done
Most AI chat plugins answer questions. Arguto actually does things — it adds products to cart, books events, submits forms, and connects to any REST API in minutes.
Adds to cart
A visitor asks for an espresso blend. Arguto recommends one in stock and drops it straight into their WooCommerce cart — no extra clicks.
Books events
"What's the next workshop?" — Arguto reads The Events Calendar, returns the upcoming session, and offers a one-click .ics download for the visitor's calendar.
Cites your content
Drop in a PDF or pick a set of pages. Arguto answers from your content and shows the source — citations, not invented facts.
From zero to a working chat in about ten minutes
1. Install
Upload the .zip from Plugins → Add New and activate. Accept the End-User Licence Agreement and you're already running on the Free plan — no licence, no card, no clicking around required. Paste a subscription ID later when you're ready to upgrade. WordPress 6.0+ and PHP 8.0+.
2. Pick a purpose
Eight pre-built purposes — site navigator, shop assistant, event concierge, support agent, knowledge explorer and more. Each ships with the right tools, system prompt and briefing pre-configured. No prompt engineering required.
3. Embed
A Gutenberg block on any page, the [arguto] shortcode in a template, or sitewide auto-inject for the floating chat widget. All three coexist — per-page embeds override the sitewide widget on those pages.
4. Safe
Every custom-tool callback is HMAC-signed — your endpoints reject anything that isn't a real Arguto request. Install tokens lock the chat to your verified domain so the Free plan can't be re-rolled by a clean reinstall. Visitor messages and tool payloads never touch your WordPress database.
What Arguto can do
Action, not just answers
Most AI chat plugins generate text. Arguto runs tools — small, audited operations on your WordPress site. It searches your shop, lists upcoming events, submits a Contact Form 7 entry, copies a coupon code to the visitor's clipboard, drops them on the right page. The visitor stays in the conversation; the work happens behind the scenes.
Purpose-driven setup
Pick what your chat is for — site navigator, shop assistant, event concierge, support agent, product expert, knowledge explorer, or a general sitewide helper — and the right tools, system prompt and knowledge mode come pre-configured. You can still tweak everything, but the defaults work out of the box.
Knowledge from your content
Arguto indexes pages, posts, products, events, or uploaded files (PDFs supported) and answers from them with citations — not invented facts. Choose the whole site, the visitor's current page, a curated set, or a folder of files. Updates flow through automatically when you edit content.
Built-in integrations
Lights up automatically when these free WordPress plugins are active.
And every visitor gets greeted in their own language — automatic translation, no admin work.
Custom REST tools in minutes
Connect any REST endpoint to your chat with a few clicks. Pick a template — OpenWeather, HubSpot, Slack, Mailchimp, Zapier, or a basic webhook — paste your API key, save. The agent now knows when to call it. Or write your own from scratch with a JSON schema and an endpoint URL.
Power users: write a webhook on any server — your WP site, a sidecar service, an internal API — and Arguto signs every request with HMAC-SHA256 so your endpoint can verify it. Two worked examples with PHP code →
Three ways to embed
Sitewide auto-inject for a chat that follows the visitor everywhere, the Arguto Gutenberg block for one specific page, or the [arguto] shortcode for posts and page builders. All three coexist; pick whichever fits your theme. The widget loads asynchronously and respects asset optimisers like Autoptimize and WP Rocket.
Built for your site, not the LLM industry's data lake
Arguto's WordPress plugin is GPL v2 and auditable. Tool callbacks between the hosted backend and your site are HMAC-signed, custom REST tool URLs go through an SSRF guard, and visitor messages flow only to the LLM that answers them — no third-party trackers, no resale, no shadow profiling.
A valid Arguto account is required for chat to function. The plugin is a thin client; the LLM orchestration runs on a hosted service operated by Fluid Interactive.

Frequently asked questions
Can I try Arguto without paying?
Yes — every new install runs on the Free plan from the moment you accept the EULA. Click Try now at the top of the page to download; no card required, no expiry. The Free plan covers about 500 visitor chats per month and resets each billing period — enough to test agent behaviour, customise overlay styles, and try every integration before you upgrade.
How many chats does each plan cover?
Standard ($19.99/month) covers about 8,000 visitor chats per month; Pro ($49.99/month) covers about 30,000. A "chat" is one back-and-forth conversation, averaging five messages each way — shorter chats stretch further; conversations that pull from large PDFs or do many back-end actions use a little more.
If a busy month uses up your allowance on either plan, the chat pauses until the next billing cycle, or you can top up — $20 adds roughly 6,000 extra chats and never expires until used.
The Free plan covers about 500 chats per month — plenty to test agent behaviour, customise overlay styles, and try every integration before you upgrade.
Standard or Pro — which one's right for me?
Most sites should start with Standard. 8,000 chats covers a typical small-to-medium business: roughly 250 conversations per day, every day of the month. You can always upgrade to Pro mid-cycle without re-installing.
Pro is for high-traffic sites, busy WooCommerce stores, or anywhere the chat is a primary support channel. You get roughly 4× the chat allowance and priority email support — answered within 24 hours rather than the usual 72.
Which LLM does Arguto use?
Arguto runs on a hosted orchestration service operated by Fluid Interactive. The current model is OpenAI's GPT family. The plugin doesn't lock you to a specific provider — we manage that on the backend, and chat behaviour stays the same as we evolve.
Where does my visitors' chat content go?
Visitor messages are sent to Arguto's backend so the LLM can answer them — that's where inference runs. The plugin does not log chat content locally by default. See our privacy policy for the full data-handling description.
Does it work on multilingual sites?
Yes. The first greeting is auto-translated to the visitor's language, and the conversation that follows continues in whatever language they type in — every language the underlying LLM supports. Per agent, you choose whether to follow the page's <html lang>, the visitor's browser, or both. Arguto's admin UI is in English and Italian today, with more coming based on demand.
Will it slow my site down?
No measurable impact in our tests. The widget is a small ES module that loads asynchronously and doesn't block your page render. Asset optimisers like Autoptimize, WP Rocket, LiteSpeed, and W3 Total Cache are detected and respected.
Can I customise the chat appearance?
Yes. Pick from built-in overlay styles — different positions, colours, and shapes — or write your own with the custom-CSS field in the admin. No theme code required. The widget plays cleanly inside both classic themes and block themes.
What happens if I cancel?
Cancel any time from your Paddle account, or send us a note. The chat keeps working until the end of your current billing period; after that the widget shows a "chat unavailable" notice on visitor-facing pages until you subscribe again.
Is the source code available?
The WordPress plugin is GPL v2 — the source is shipped with every install and you're welcome to audit, modify, or fork it. The hosted orchestration backend that runs the LLM and tool calls is proprietary; that's where the recurring infrastructure cost lives.
