From quick installation to full deployment, Helper makes it easy to add an intelligent AI chatbot to your site — one of the best solutions for smart, scalable interaction.

Key Features & Capabilities

Below is a more detailed breakdown of what the plugin offers. 

1. AI-Powered Conversations (GPT-3 / GPT-4 / Assistant API)

• Use OpenAI’s GPT-3, GPT-4, or “Assistant API” modes to generate responses.
  
• Control model parameters (temperature, max tokens, etc.) for balancing creativity vs. precision.
  
• Support for longer memory and instruction-based control via the Assistant API (making conversations more coherent over multiple exchanges).
  

2. Content & Context Awareness

• Bot can reference your site’s content (posts, pages, documentation) to generate replies grounded in your topical material.
  
• It can also access your WooCommerce product catalog, including attributes, variants, stock status — enabling it to answer questions about your products or even assist in product selection.
  
• Optionally include external content like PDF files (e.g. manuals, guides) in prompts so the bot can reference them.
  

3. Multi-Mode & Flexible Use Cases

• Comes in different “modes” — pure AI chat, FAQ / Q&A mode (where you predefine question/answer pairs), data-collection forms, surveys, or hybrid setups combining multiple modes.
  
• You can switch off the AI mode and rely solely on FAQ or form-based interaction if desired.
  
• Bot logs to track past user queries and responses, useful for analyzing interaction trends or improving prompts.
  
• Ability to collect user data (e.g. email, name, custom fields) for lead capture, analytics, or follow-up.
  
• Google Analytics integration: certain events (like form submissions) can be sent to your analytics system.
  

4. Voice & Speech Interaction (WebSpeech API)

• Text-to-Speech (TTS): Bot can “speak” its replies using WebSpeech API. Supports over 40 languages and 160+ voices.
  
• Speech Recognition / Voice Input: Users can speak their messages instead of typing, enhancing accessibility and user experience.
  

5. Styling, Position & Display Control

• You can style every chat window element — colors, fonts, borders, backgrounds, sounds, sizes, etc. Live preview helps you fine-tune the look. 
• Supports 8 predefined bot button positions (corners, fixed positions, etc.).
  
• Chat can be placed via shortcodes, so you can embed it anywhere (posts, pages, templates).
  
• Customizable greeting phrases, opening animations, and sound effects.
  
• Option to preserve (save and restore) the bot’s last response, so when someone returns or navigates pages, the context isn’t lost.
  

6. Behavior & Human Simulation

• The bot can simulate “typing,” pauses, and response delays to feel more natural / humanoid.
  
• Adaptive behavior: over time the bot can “learn” from interactions (via logs or prompt tuning) to improve answer relevance.
  

7. WooCommerce & eCommerce Integration

• Deep compatibility with WooCommerce: the bot can answer product questions (attributes, comparisons, availability), cross-sell or recommend items.
  
• In high-volume stores, the bot can manage numerous simultaneous conversations about products without downtime or scaling issues.
  

8. Performance, SEO & Compatibility

• Lightweight and optimized for performance so it doesn’t bloat your site or slow it down.
  
• SEO-friendly (the plugin claims it is built with SEO in mind) and cross-browser compatible: supports major browsers (Chrome, Firefox, Safari, Edge, Internet Explorer)
  
• Designed to play nicely with most themes, page builders, and performance optimizers — you may need to exclude chat script loading from aggressive defer/minification.
  

9. Support, Documentation & Updates

• Comes with an installation guide, a detailed user manual, and presumably updates from the author.
  
• Bot logs and analytics help you monitor how the bot is performing, identify weak spots, and refine prompts or content.
  

Potential Use Cases & Value Propositions

• Automate first-level customer support, reducing repetitive ticket load and freeing up human agents.
  
• Turn your product catalog into an interactive shop assistant, helping visitors choose, compare, or find items.
  
• Capture leads by collecting user info conversationally, qualifying them, and passing to CRM or email marketing.
  
• Use the bot for surveys or feedback (ask questions, collect responses).
  
• Use the FAQ / predefined Q&A mode for low-maintenance help centers (less API usage).
  
• Deliver localized, multilingual support out of the box, ideal for international audiences.
  
• Maintain a consistent brand voice 24/7 without extra staffing.

4. ACF to REST API

When building headless WordPress sites or integrating with modern JavaScript frameworks like React, Vue, or Next.js, developers often rely on Advanced Custom Fields (ACF) to structure their content. The ACF to REST API plugin is the missing link that exposes your ACF data through WordPress’s native REST API.

This means you can query, manipulate, and display custom field data just like any other WordPress resource — making ACF-powered sites more flexible and API-friendly than ever.

Key Features

• Expose ACF fields in the REST API: Makes custom data accessible to external apps or frontend frameworks.
  
• Support for all ACF field types: From text and image fields to repeaters and flexible content.
  
• Compatibility with WordPress’s native API routes: No need for custom endpoints.
  
• JSON response format: Clean, developer-ready data output.
  
• Customizable visibility: Choose which fields are exposed for security or performance.
  

Whether you’re building a custom dashboard, mobile app, or headless frontend, ACF to REST API provides a reliable bridge between your structured content and modern web technologies. It’s one of the most powerful tools for developers who want to extend WordPress beyond traditional themes.

5. REST API OAuth 1.0a

Security is at the core of every successful API integration. The REST API OAuth 1.0a plugin ensures your WordPress REST API remains secure by providing a robust authentication system for external connections.

OAuth 1.0a has long been a standard for verifying access between clients and servers, and this plugin brings that same level of protection to your WordPress setup. Whether you’re connecting mobile apps, headless frontends, or third-party platforms, it ensures that only authorized requests can access your data.

Key Features

• Implements OAuth 1.0a authentication for REST API requests.
  
• Secure token-based access: Prevents unauthorized data exposure.
  
• User-specific keys and permissions: Control who can read or write data.
  
• Developer-friendly setup: Add tokens via the admin dashboard or programmatically.
  
• Compatible with custom and default REST routes.
  

If you’re using the WordPress REST API for external integrations, this plugin is a must-have layer of security. In 2025, with cyber threats more advanced than ever, a well-protected API is not optional — it’s essential.
