Resolver – AI Chatbot

Description

Resolver is an AI chatbot plugin built natively for WordPress. Train it on your site’s pages and watch it answer customer questions intelligently for you.

Get a break from customer support

With Resolver, you can save hours of emailing every week. Resolver works 24/7 to answer visitor questions on your website, replying in seconds
and using the full knowledge of your website’s content.

The auto-training chatbot

Choose which pages you want to train your chatbot with, and Resolver will index them in seconds. Then, if you make an edit to a page, Resolver will automatically retrain on the new content.

Even better, you can tell Resolver which page types to track, and it will automatically train on new pages as they’re published. This lets you
focus on building your business, instead of managing your chatbot.

No monthly subscription

Unlike expensive SaaS apps, Resolver doesn’t upcharge you for “AI credits.” Instead, you’ll enter your own API key for Anthropic, Google, or OpenAI.

This way, you pay the AI platform directly for your actual API usage, leading to huge savings in comparison to a SaaS app.

After installing the Resolver plugin, you can launch a highly intelligent chatbot in minutes.

  1. Connect to an AI platform
  2. Choose the pages to train your chatbot with
  3. Launch the chat widget across your site

All features

Who should use Resolver?

Use it as a customer support chatbot, a WooCommerce chatbot, an FAQ chatbot, or a general website chatbot.

Resolver is a self-hosted WordPress chatbot with no monthly subscription and no AI credits, powered by ChatGPT, Claude, or Gemini using your own API key.

Who is behind this?

The Resolver AI chatbot plugin is built and maintained by Ben Sibley and Andrew Mead. They are the same team behind the popular Independent Analytics plugin.

External services

Resolver answers visitors using an AI provider you choose: OpenAI, Anthropic, or Google. It connects to that provider’s API with your own API key. Nothing is sent to a provider until you connect it. Chats and training data are stored in your site’s database.

OpenAI API

Used for chat replies, and for embeddings, if you choose OpenAI for either.

  • When training: the text of each post, page or product you train on is sent to create its embeddings. This includes its title, its content and, if you turn them on, its excerpt and author name.
  • When a visitor sends a message: the message is sent to create an embedding, to search your trained content. For a reply, it’s sent along with the chat’s earlier messages, your chatbot’s instructions, and the passages of your site’s content that best match the question, with their page addresses. Visitors’ IP addresses and the pages they’re on are not sent.

Anthropic API

Used for chat replies, if you choose Anthropic (Claude). When a visitor sends a message, it’s sent along with the chat’s earlier messages, your chatbot’s instructions, and the passages of your site’s content that best match the question, with their page addresses. Anthropic doesn’t provide embeddings, so training uses OpenAI or Google.

Google Gemini API

Used for chat replies and embeddings, if you choose Google for either. The same data is sent, at the same times, as described for OpenAI above.

Freemius

Resolver uses Freemius for opt-in usage data, licensing and upgrades to Resolver Pro. Nothing is sent unless you opt in when Resolver asks, or activate a Pro license. Then Freemius receives your site’s address and title, your WordPress and PHP versions and site language, the plugin’s version and whether it’s active, and your name and email address. Your list of plugins and themes is sent only if you allow it.

This is the best WordPress plugin I have seen for years. It's been incredibly well thought out, and that makes it easy to use. The a setup process walks you through everything you need step by step, so don't worry if you don't have much knowledge of AI. You just make sure your API keys are entered into the WordPress connector plugin and and Resolver takes you through the setup. I've used subscription services in the past that have cost a small fortune per month to do the same things that this plugin does for free. You are of course paying for the API usage, but the plugin gives you full control of how many tokens it uses per month and on the right model API usage is very cheap.

This is an easy to use, fully documented, and useful tools for ansewring your user question from the website own content, esp. I think for multilingual websites. Nice Job.

This 5 star app is awesome and so easy to use, even for a newbie like me. The install was straight forward and seamless. Ben's step by step knowledge base is so helpful and easy to understand. And now I have a cool AI chatbot helping out on my site!
