설명
Sparxio is a free AI chatbot for WordPress that answers customer questions 24/7 — using your own website content, FAQs and documents. Add your AI key, teach it about your business, and it starts helping visitors in minutes: answering questions, capturing leads, and guiding people toward a purchase, a booking or an enquiry.
You use your own API key from OpenAI (ChatGPT), Anthropic (Claude), Google Gemini or 7 other providers, so you pay the provider directly — no Sparxio subscription, no per-message markup, no middleman.
How it works
- Connect your AI — paste an API key from OpenAI, Claude, Gemini, DeepSeek, OpenRouter (free models available) or another provider.
- Teach it your business — add FAQs, upload PDF/DOCX/TXT files, or import pages and your sitemap into the knowledge base.
- Go live — the chat widget appears on your site automatically. Visitors get instant answers; you get the leads and chat logs.
Perfect for
- Customer support — answer common questions instantly, day and night, and reduce support emails
- Lead generation — collect names, emails and phone numbers right inside the chat
- Small businesses and local shops — share opening hours, services, prices and contact details accurately
- Agencies and freelancers — set up a branded AI assistant for client sites in minutes
- Online stores — product questions and order help (WooCommerce features in Sparxio Pro)
- Multilingual sites — the AI replies in the visitor’s language, and the widget interface ships in 30 languages
Why Sparxio
- Free and fully working — no message limits, no time limits, no license key needed
- Bring your own AI key — full control of cost; most conversations cost a fraction of a cent
- Answers from your content — grounded in your knowledge base, not generic replies
- Doesn’t make things up — “Only answer from what you know” (on by default) stops the bot inventing phone numbers, prices or policies
- Fast and lightweight — loads after your page, isolated with Shadow DOM, no theme conflicts, mobile-friendly
Free features
- 10 AI providers — OpenAI (ChatGPT / GPT), Anthropic (Claude), Google Gemini, xAI (Grok), DeepSeek, Mistral, Groq, OpenRouter (hundreds of models, including free ones), a local Ollama model, or any OpenAI-compatible API (Together, Fireworks, Cerebras, Perplexity, LM Studio…). Use any model ID, including newer ones
- Backup AI provider — if the main provider fails, a backup answers automatically, so your chatbot never goes silent
- Unlimited knowledge base — FAQs, documents (PDF, DOCX, TXT, MD, CSV), web pages and whole sitemaps
- Lead capture & CSV export — collect contact details in the chat, manage them in Sparxio Leads, export to CSV
- Chat logs — read every conversation, with device and page (and country behind Cloudflare)
- Full branding control — colour presets or your own colours, header icon, brand name, greeting and CTA button. No “powered by” link unless you add one
- 30-language widget — English, Arabic, Chinese, Dutch, French, German, Hindi, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Turkish, Ukrainian and more, with browser language auto-detection
- OpenRouter model browser — search live models, free ones first, with prices
- Ready-made prompt templates — e-commerce, SaaS, travel, healthcare, education and real estate
- Cost controls — history limits, rolling summaries and session timeouts keep API usage low

Sparxio Pro (optional, separate plugin)
Everything above is free. For stores and teams that want more, Sparxio Pro adds:
- WooCommerce AI chatbot — product search with product cards, add to cart, and verified order-status lookups in the chat
- Live chat agent takeover — jump into any conversation in real time, then hand it back to the AI
- Advanced analytics — conversations, leads, top questions, and revenue from orders placed after a chat
- Proactive engagement & office hours — greet visitors by time on page, scroll or exit intent
External Services
This plugin contacts the third-party services below only when you configure or choose them. Nothing is sent to any third party unless you add an AI provider key, or opt in to Freemius when activating the plugin.
AI providers. When a visitor sends a chat message, the plugin sends that message, the recent conversation history, your system prompt, and any matching knowledge-base excerpts to the AI provider you selected in AI Settings, using your own API key. Nothing is sent until you add a key and select a provider. Only the selected provider is contacted — plus the backup provider you may choose in AI Settings, and only when the selected one fails.
- Anthropic API (api.anthropic.com) — used when Anthropic is the selected or backup provider. Terms / Privacy
- OpenAI API (api.openai.com) — used when OpenAI is the selected or backup provider. Terms / Privacy
- Google Gemini API (generativelanguage.googleapis.com) — used when Gemini is the selected or backup provider. Terms / Privacy
- DeepSeek API (api.deepseek.com) — used when DeepSeek is the selected or backup provider. Terms / Privacy
- OpenRouter API (openrouter.ai) — used when OpenRouter is the selected or backup provider. OpenRouter forwards the request to the model you choose (and to your backup models, if set). Your site URL and site name are also sent as attribution headers. When OpenRouter is selected or has a key and an administrator opens AI Settings, the public model list (openrouter.ai/api/v1/models) is fetched, without a key or any site data, and cached for six hours.

- xAI API (api.x.ai) — used when xAI (Grok) is the selected or backup provider. Terms / Privacy
- Mistral AI API (api.mistral.ai) — used when Mistral is the selected or backup provider. Terms / Privacy
- Groq API (api.groq.com) — used when Groq is the selected or backup provider. Terms / Privacy
- Custom OpenAI-compatible endpoint — used when “Custom” is the selected or backup provider. Requests go only to the address you enter (for example Together, Fireworks, Cerebras, Perplexity, or your own LM Studio / vLLM server); that service’s own terms and privacy policy apply.
- Ollama (your own server, default http://localhost:11434) — used when Ollama is the selected or backup provider. Requests go only to the Ollama server address you enter; no third party is contacted.
Other services.
- Freemius (api.freemius.com) — only if you choose to opt in when activating the plugin (you can skip it). Sends your site URL, WordPress and plugin versions, and your admin name and email, so you can receive optional security and feature notices and manage a Pro license. Terms / Privacy
Knowledge base imports. When you import a web page or sitemap, your site fetches that address (and the pages a sitemap lists) directly. Only the address you enter is requested; downloads are size-limited and private/internal addresses are refused.
Cookies and browser storage. The widget keeps the conversation in this browser according to your Chat Persistence setting (memory only, this tab, or this browser). A sparxio_seen cookie remembers returning visitors. On WooCommerce stores with Sparxio Pro, a sparxio_attr cookie (a signed conversation number, not the conversation itself), set once the visitor has sent a message, lets an order placed later be counted as chat-assisted.
No data is sent to any AI service until you enter an API key and a visitor starts a chat. The plugin does not look up visitor locations with any outside service. API keys are stored in your own WordPress database.
Payments, licensing, and Pro updates are handled by our partner Freemius (checkout, invoicing, and license management). See the Freemius Privacy Policy.
Source Code and Build
This plugin ships its complete, human-readable source. No build step, bundler, or minifier is used.
- assets/js/widget.js — the chat widget script. This is the original hand-written source (written by hand; it is not minified).
- All admin scripts in assets/js/ are likewise plain, hand-written source.
Bundled third-party code: the Freemius SDK (vendor/freemius, GPL), used for opt-in usage analytics and to offer the optional Pro version. Source: https://github.com/Freemius/wordpress-sdk. The free plugin bundles no other third-party JavaScript libraries; Sparxio Pro additionally bundles Chart.js (MIT, https://www.chartjs.org/) for its analytics charts. The widget uses your visitors’ system fonts, so no web fonts are downloaded.

FAQ
-
Is Sparxio really free?
-
Yes. The plugin is free and fully functional, with no message limits, time limits or license checks. You only pay your AI provider for usage. Sparxio Pro is an optional separate plugin for WooCommerce chat, live agent takeover, advanced analytics and proactive engagement.
-
Do I need an API key?
-
Yes. Sparxio uses your own key, so you stay in control of usage and cost. Supported: OpenAI, Anthropic (Claude), Google Gemini, xAI, DeepSeek, Mistral, Groq, OpenRouter, a local Ollama model, or any OpenAI-compatible API.
-
Can I use it as a ChatGPT chatbot for my website?
-
Yes. Choose OpenAI in AI Settings, paste your OpenAI API key, and pick a GPT model. You can switch to Claude, Gemini or another provider at any time without losing your knowledge base or settings.
-
Is there a free AI option?
-
Yes. OpenRouter offers free models, and Google Gemini and Groq have free tiers. Free tiers have rate limits set by the provider, so for busy sites a low-cost paid model is recommended.
-
How much does the AI cost to run?
-
You pay your provider directly. On affordable models this is usually a fraction of a cent per conversation. History limits, summaries and session timeouts keep usage low.
-
How do I train the chatbot on my business?
-
Open Sparxio Knowledge Base and add FAQs, upload PDF, DOCX, TXT, MD or CSV files, or import web pages or your whole sitemap. The bot uses this content to answer questions.
-
Will the chatbot make things up?
-
With “Only answer from what you know” (on by default), the bot only states facts like phone numbers, addresses, prices and policies that you have given it. If it doesn’t know, it says so and offers a next step instead of guessing.
-
Can it capture leads?
-
Yes. Turn on lead capture and the chat asks for name, email and phone after a number of messages you choose. Leads appear in Sparxio Leads and can be exported to CSV.
-
Will it slow down my site?
-
No. The widget loads after your page content and runs inside Shadow DOM, so it doesn’t conflict with your theme’s CSS or JavaScript.
-
What languages are supported?
-
The AI replies in whatever language the visitor writes in, and the widget interface ships in 30 languages. Set a default language and turn on browser auto-detection in Sparxio Behavior.
-
Does it work with WooCommerce?
-
The free plugin works on any WooCommerce site as a support chatbot. Product search, add-to-cart and order-status lookups inside the chat are part of Sparxio Pro.
-
Can I customise the AI’s personality?
-
Yes. Write a system prompt that sets the assistant’s name, tone, knowledge and rules, or start from one of the included templates.
-
Is my visitors’ data safe?
-
API keys are stored in your own database, and messages go only to the AI provider you choose. No visitor location lookup service is used. See External Services above for every connection.
-
How do I remove all data when uninstalling?
-
Data is kept by default. To delete everything, enable “Delete all data on uninstall” in Sparxio AI Settings Security before removing the plugin.

변경이력
3.7.5
- An empty or damaged server response is no longer treated as an answer: the widget fetches the real answer for the same message instead, so it is never sent twice
- A message the server received but could not answer is now labelled “Answer unavailable” instead of “Not sent”
3.7.4
- Faster replies: a message is sent the moment the visitor presses Send and the typing indicator appears at once; the artificial pauses before sending and after the answer are gone (the Pre-Typing Delay and Typing Speed settings were removed)
- Every chat and session request now has a time limit. If a reply is slow or the connection drops, the widget keeps asking for the same message’s answer for up to about 2½ minutes, without the message being stored or answered twice
- A message the server is still answering is picked up automatically when ready, instead of showing a “still being answered” error
- Sending a message again updates its existing bubble instead of adding a duplicate; each visitor message shows Sending… / Waiting for reply / Not sent until it is answered
- A message sent just before a page reload gets its answer after the reload (Tab and Browser persistence modes)
- AI providers updated for current models: Claude 5.5 family, GPT-6 / GPT-5.x, Gemini 3.x and 2.5, DeepSeek V4 (deepseek-flash, deepseek-v4-pro), current OpenRouter models. Reasoning models get the right options (low effort, room for thinking), so replies are fast and never empty; thinking text is never shown to visitors
- Retired models are switched to a current one on upgrade and, if a model disappears later, at runtime (with a notice in AI Settings)
- New providers: xAI (Grok), Mistral AI, Groq, and Custom (any OpenAI-compatible API)
- New: backup AI provider, custom model ID for every provider, OpenRouter live model list and backup models, “Only answer from what you know” accuracy setting (on by default)
- Gemini API key is sent in a header instead of the URL; OpenRouter errors returned inside a successful response and Ollama HTTP errors are now reported in AI Settings
- Test Connection shows the model used and how long it took
- Every widget request (live-agent updates, lead form, add to cart, summaries) now has a time limit, so a stalled connection can’t freeze the chat
3.7.3
- Retrying a message whose answer is still being written keeps the same identity (also across a page reload in Tab/Browser mode), so it is never saved or answered twice; a retry gets the original answer back, including product cards
- A saved conversation is tied to its key: if the key had to be replaced, earlier messages stay visible and a new conversation starts instead of a broken one
- Knowledge base: page addresses keep their exact path and query (for example /Guide and /guide are separate pages); only the scheme and host are case-insensitive
- Pro: opening an empty chat no longer replaces the order attribution of an earlier conversation — it is set only after a visitor message is accepted
- Pro: the conversion rate now compares the same conversations (started in the period) instead of mixing two groups
- Packaging: removed a stray runtime file
3.7.2
- Live agent: agent replies are now saved as one message in the conversation transcript, so the admin screen and the visitor see the same messages with the same IDs; your own reply is no longer shown twice when the screen refreshes at the same moment
- Saving problems are reported: if an AI answer could not be stored it is still shown, with a note; hand-off and “release to bot” report failures instead of claiming success
- Retrying after a lost connection no longer saves a lead or message twice, and does not pay for a second AI answer
- Product cards now also appear when a chat returns from a human agent to the AI; the visitor’s language is kept
- Trusted proxy list: malformed entries (such as a wrong /prefix) are rejected and reported
- Rate limiting is now exact under simultaneous requests, also on sites without an object cache
- Conversations end on the server after the Session Timeout; “None” and “Tab” persistence now behave as described; old session cookies are migrated or removed
- Knowledge base: each web page is identified by its address (two pages with the same title stay separate), a failed re-import keeps the previous version, imports are size-limited, and sitemap imports can continue where they stopped
- Pro: office hours support overnight ranges and fall back to the site timezone; analytics use the selected period, site timezone, paid orders minus refunds and each order’s currency
- Pro: order lookup understands short order numbers and an email sent in a following message (both are still required)
3.7.1
- Fixed: the “Start free trial” button opened a blank page
- Chats switched back from a human agent to the AI now show the AI’s reply instead of losing it
- Live agent screen: fewer duplicated or skipped messages
- Lead form: double-clicking while the chat is starting can no longer send the lead twice
- Visitor messages and agent replies report an error if they could not be saved
- Proxy setting: choose None, Cloudflare (verified against Cloudflare’s published IP ranges) or your own trusted proxy IPs
- Removed the optional ip-api.com geolocation. With Cloudflare, the visitor’s country comes from Cloudflare’s own header; no visitor data is sent to a third party
3.7.0
- Privacy: visitor geolocation is now off by default and must be switched on by the site owner; the widget no longer loads Google Fonts
- Language settings (multi-language, default language, auto-detect) are now available to everyone under Sparxio Behavior
- Lead form only confirms success after your details are actually saved, and keeps what you typed if saving fails
- Rate limiting now uses the real visitor IP by default, with an option for sites behind Cloudflare or a proxy
- Knowledge base search now understands Urdu, Arabic, Chinese and accented languages
- CSV exports are protected against spreadsheet formula injection
- Deleting a chat now also removes its related live-agent messages
- Safer session keys and clearer messages when the chat cannot connect
3.6.5
- First public release on WordPress.org.
