An AI chatbot powered by Anthropic Claude, running on your WordPress site
SleekAI adds an AI chatbot for Chatbot Powered by Anthropic to your WordPress site. It answers from the content you choose, such as posts, pages, custom post types, post meta, taxonomies and user data, with your own OpenAI, Anthropic, Google, or OpenRouter key.
Claude is a particularly good fit for WordPress chat
By 2026 the lineup is Opus for the hardest tasks, Sonnet for everyday production work, and Haiku for cheap high-volume traffic.
SleekAI ships native Anthropic support.
Going through Anthropic directly also keeps the data path clean. Your WordPress site sends prompts to api.anthropic.com using your key, the response comes back, the conversation logs locally. There is no third-party SaaS in between rebroadcasting your prompts. That matters for sites in regulated industries where the data path documentation is part of the compliance review.
Features
Full Claude lineup
The model choice is per chatbot record so each persona uses what fits its budget.
Direct API path
Prompts go straight to api.anthropic.com from your server. No SaaS proxy, no third party sitting in the data path, clean for compliance reviews.
Answers from your data
Map post titles, content, post meta, taxonomies or a WP_Query into the instruction, and the bot answers from what your site actually publishes.
Where Claude earns its keep on WordPress
Developer documentation
Haiku reads code-heavy docs and answers technical questions cheaply at scale.
Sales and consultative chat
Sonnet handles plan comparisons, prorated upgrade math, and competitor questions with the kind of nuance that closes deals. Per-conversation cost is still low compared to the value of a converted visitor.
Repeat questions
Answer the questions visitors ask every day from the pages and posts where you already answer them.
How the Claude integration fits together
Map your data
Choose the posts, fields, taxonomies or users the bot should know and reference them in the instruction.
Pick a model per chatbot
Each chatbot record has a model dropdown. Pick Opus, Sonnet, or Haiku based on the persona’s role.
Set display conditions
Decide which pages, post types, roles or logged-in states show the chatbot.
Pick a model
Store your OpenAI, Anthropic, Google or OpenRouter key once in the shared AI settings, or add a compatible endpoint, and choose the chatbot’s model.
Why running on Anthropic matters
Picking a model provider is now a meaningful product decision rather than a commodity choice. The lineup is wide enough to cover both cheap high-volume traffic on Haiku and demanding agent work on Opus, with one API key and one billing relationship.
For a WordPress site that runs multiple chatbot personas this lineup maps almost one-to-one to the personas. The docs persona wants fast and cheap, that is Haiku. The sales persona wants nuance and clean comparisons, that is Sonnet.
The direct API path also matters for organizations that take their data path documentation seriously. Going through Anthropic’s API directly with your own key keeps the surface area small. There is no third-party SaaS proxy rebroadcasting prompts, no extra contract, no extra retention question.
The compliance review for an Anthropic-only setup is the simplest possible version of that review. All of that lines up cleanly with the SleekAI design goal of keeping infrastructure inside WordPress and only reaching out to the model provider itself.
Frequently asked questions
Which Claude models does SleekAI support?
All Anthropic models currently exposed by the public API: Claude Opus, Sonnet, and Haiku across recent generations.
Is my Anthropic API key stored securely?
The plaintext key is only loaded into memory at request time when calling the API and is never logged.
Does the chatbot need internet egress to api.anthropic.com?
Yes. The WordPress server must be able to reach api.anthropic.com over HTTPS. Most managed WordPress hosts allow outbound HTTPS by default. For locked-down hosts with egress allowlists, add api.anthropic.com to the allowed destinations.
Does Anthropic train on my data?
Per Anthropic’s commercial API terms, customer prompts and completions are not used to train models by default. SleekAI does not change that contract since it just calls the standard API with your key.
Can I mix Claude with other providers in the same site?
Yes. The model choice is per chatbot record, so you can run a sales persona on Claude Sonnet and a free-tier persona on a cheaper provider. SleekAI normalizes the request and response shapes internally, so the rest of the integration is identical.
Which AI providers does it support?
OpenAI, Anthropic, Google and OpenRouter, plus custom OpenAI-compatible endpoints. You bring your own API key and the provider bills you directly.
Where does the chatbot get its answers?
From the WordPress data you map into its instruction: post titles and content, post meta, ACF and Meta Box fields, taxonomies, terms, users and user meta, or a WP_Query. Values resolve on every request.
Can it act on a visitor’s behalf?
No. A chatbot answers questions.
