Resolver - 2026 Pricing, Features, Reviews & Alternatives

Resolver is a WordPress chatbot plugin that automates customer support by training on a site's own content and routing visitor queries through user-supplied AI model APIs. Compatible with OpenAI (ChatGPT models), Google Gemini, and Anthropic Claude, Resolver generates responses from whichever model the administrator selects. The plugin is installed like any standard WordPress plugin; AI inference runs cloud-side through the user's own API keys, keeping the deployment self-hosted while offloading compute to third-party providers. A free tier is available with no limits on chats, training pages, or domains, alongside an optional Pro upgrade that unlocks advanced analytics, PDF training, WooCommerce product field training, custom post field training, user feedback tracking, and human-agent request monitoring.

Resolver trains automatically on selected site pages and retrains whenever tracked content is updated, with an option to auto-train on newly published pages. Training can span over 1,000 pages in seconds and extends to PDF files in the WordPress Media Library (Pro), custom post fields (Pro), and WooCommerce product fields (Pro), making it applicable to e-commerce operators, general web publishers, and any WordPress-based business requiring always-on support coverage. Visibility settings control which pages display the chatbot, and a preview mode allows administrators to test behavior before going live.

Cost control is a core design consideration in Resolver: users pay only for API token consumption rather than a fixed SaaS subscription fee. Token monitoring tracks daily and monthly usage, and configurable limits prevent unexpected overages. Chat history stores all conversations for review, while Pro-tier chat analytics and user feedback signals (likes, dislikes, human-agent requests) provide data for ongoing optimization. A Pro Agency plan covers unlimited sites, addressing the needs of freelancers and agencies managing multiple WordPress installations.
