aGo AI Chatbot is a free AI chat widget for WordPress. Add a floating chatbot to any site in minutes. Upload your own knowledge files (PDF, TXT, CSV, Markdown, JSON) and the AI answers visitor questions using that content, in their language, around the clock.
This plugin is free and fully functional. No chat caps, no file limits, no signup, no upsell modals. You use your own Google Gemini API key (Google offers a generous free tier). The plugin never contacts any aGo server.
<h4>Why aGo AI Chatbot?</h4>
<ul>
<li>Your content, your answers. The bot grounds its responses on the documents you upload. No hallucinations from random training data.</li>
<li>Free, not freemium. The plugin is 100% functional out of the box. There is no usage cap to pressure you into a paid version.</li>
<li>Privacy-first. Visitor messages go to Google under your API key. The plugin does not store conversations, does not phone home, does not track anyone.</li>
<li>Lightweight. ~30 KB widget JS. No CDN dependencies. Works on any theme.</li>
<li>Multilingual. The AI replies in the language the visitor writes. Admin UI in English, Spanish, Portuguese (Brazilian).</li>
</ul>
<h4>Core features</h4>
<ul>
<li>AI chat widget in any page (configurable position: left/right, vertical offset to avoid clashing with floating buttons).</li>
<li>Knowledge base from your own files, PDF, TXT, CSV, Markdown, JSON. Unlimited uploads.</li>
<li>Configurable bot identity, name, welcome message, tone (friendly / professional / casual / formal), response style, avatar.</li>
<li>System prompt for fine-grained instructions (industry, audience, rules).</li>
<li>Google Gemini File Search Store under the hood, documents are indexed once, only the relevant fragments are sent to the model, keeping your API cost low.</li>
<li>Anti-abuse rate limit per IP (default 60 messages/minute, configurable) to protect your Gemini quota from automated flooding.</li>
<li>Works with every page builder: Elementor, Divi, Bricks, Gutenberg, classic, the widget is rendered via <code>wp_footer</code> regardless of the theme.</li>
</ul>

</ul>

</ul>
<h4>Powered by</h4>
This plugin uses the Google Gemini API (“Gemini” is a trademark of Google LLC). aGo Lab is not affiliated with Google.
<h4>Pro companion (optional, not on WordPress.org)</h4>
A separate paid companion plugin (distributed only from store.ago.cl) adds features that this free plugin does NOT include: conversation history, lead capture forms, multi-provider failover (OpenAI/Anthropic/Groq/Cohere), analytics dashboard, voice input/output, handoff to human (Email/Slack/Telegram), WooCommerce product knowledge, white-label. The free plugin works fully on its own; the Pro is purely additive.
<h3>External services</h3>
This plugin relies on Google Gemini, an external service operated by Google. It is used to:
<ul>
<li>Generate chat responses from your knowledge files and visitor messages.</li>
<li>Upload, store and index your knowledge files in a Gemini “File Search Store” so the model can answer with your content.</li>
<li>List the Gemini models available to your API key.</li>
</ul>
What is sent: every visitor message and conversation history (while the chat is open), your knowledge files, your Gemini API key in the request headers. No data is sent without an explicit administrator action (uploading a file, configuring the API key) or a visitor interacting with the chat widget you have enabled.
