Creator Assistant Hub is the core infrastructure plugin of the Creator Assistant ecosystem. It connects your WordPress site to OpenAI and Qdrant to automatically generate and store vector embeddings for your content, enabling semantic search and AI-powered features.
How it works
The Hub is the shared infrastructure layer for the Creator Assistant ecosystem. When a compatible add-on is active and activates a vectorizer, the plugin generates vector embeddings via the OpenAI API and stores them in your Qdrant vector database cluster whenever a post is published or updated. This makes your content available for semantic search and retrieval by Creator Assistant add-ons. Without an active add-on, the Hub runs in standby mode — no content is sent to external services.
Key features
<ul>
<li>Automatic post vectorization — when an add-on activates a vectorizer, embeddings are generated and stored whenever a post is published or updated. Without an active add-on, no vectorization takes place.</li>
<li>Chunk-based vectorization — splits post content into word-level segments and stores each chunk as a separate Qdrant point, enabling fine-grained retrieval (activated by add-ons via filter).</li>
<li>Summary-based vectorization — generates a short AI summary of each post via OpenAI Chat Completions, then embeds and stores a single point per post for high-level semantic search (activated by add-ons via filter).</li>
<li>Background batch vectorization — an hourly cron job automatically picks up any existing posts that have not yet been vectorized, so your entire content library is indexed without manual intervention.</li>
<li>OpenAI integration — uses the <code>text-embedding-3-small</code> model (1536 dimensions) via the OpenAI Embeddings API for all vectorizers; the Summary vectorizer additionally calls the OpenAI Chat Completions API (<code>gpt-4.1-nano</code>) to generate post summaries.</li>
<li>Qdrant integration — stores and retrieves vector embeddings from your Qdrant Cloud cluster. Two collections are used: <code>post_chunk</code> for chunk-level points and <code>post_summary</code> for post-level summary points.</li>
<li>Block editor panel — shows the vectorization status of each post directly in the block editor sidebar (document settings panel).</li>
<li>Post list column — adds a “Vector Status” column to the posts and pages admin list, showing the vectorization status of each entry at a glance.</li>
<li>Settings page — configure OpenAI API key, Qdrant endpoint and API key, and cache expiration from a dedicated admin page.</li>
<li>API response caching — configurable cache duration to reduce API usage and latency.</li>
<li>Site Health check — reports the Hub service status in the WordPress Site Health screen.</li>
<li>Qdrant keep-alive — sends a daily lightweight ping to prevent free-tier Qdrant Cloud clusters from being suspended.</li>
<li>WPML compatible — detects the post language via WPML hooks (when WPML is active) and includes it in the Qdrant payload for multilingual filtering.</li>
<li>Extensible — exposes actions and filters so add-ons can register additional post types, override vectorizer behaviour, customise Qdrant payloads, and add settings tabs.</li>
</ul>
Requirements
<ul>
<li>An <a href="https://platform.openai.com/" rel="nofollow ugc">OpenAI</a> account with a valid API key.</li>
<li>A <a href="https://cloud.qdrant.io/" rel="nofollow ugc">Qdrant Cloud</a> account with an active cluster (free tier is supported).</li>
<li>WordPress 6.6 or higher.</li>
<li>PHP 7.4 or higher.</li>
</ul>
External services
This plugin connects to two third-party services. By using this plugin you agree to their respective terms and privacy policies.
<ul>
<li>
OpenAI — used to generate vector embeddings from your post content via the Embeddings API. When the Summary vectorizer is active (enabled by an add-on), post content is also sent to the Chat Completions API to generate a short AI summary before embedding.

Data is only transmitted to these services after you explicitly accept the Creator Assistant Terms of Service in the plugin settings and provide your own API credentials. No data is transmitted automatically upon activation.

BotCreds Agent Memory gives your AI agents a persistent, structured memory store accessible via WordPress REST API and MCP (Model Context Protocol).
Two modes of operation:
<ul>
<li>KV Mode (default) — Simple key-value store with tags, expiry, and text search. No external dependencies. Works out of the box.</li>
<li>Vector Mode — Add an OpenAI API key to unlock semantic search powered by embeddings. Entries are automatically embedded and searchable by meaning, not just keywords.</li>
</ul>
Key features:
<ul>
<li>REST API with full CRUD (create, read, update, delete)</li>
<li>MCP endpoint for AI agent tool integration</li>
<li>Namespace-based access control per WordPress user</li>
<li>Automatic embedding generation via WP-Cron</li>
<li>Bulk backfill for existing entries</li>
<li>Expiry support for temporary memories</li>
<li>Tag-based filtering and organization</li>
<li>WordPress Application Password authentication</li>
</ul>
Built for AI agents, by AI agents.
Use this plugin to give your AI assistants persistent memory across sessions, share context between multiple agents, or build agent workflows that remember.
<h3>External services</h3>
This plugin optionally connects to the OpenAI API to generate vector embeddings for semantic search.
<ul>
<li>Service: OpenAI Embeddings API (<code>https://api.openai.com/v1/embeddings</code>)</li>
<li>When it is used: Only when an OpenAI API key is configured in the plugin settings. Without a key, the plugin operates in KV-only mode and makes no external requests.</li>
<li>What is sent: The text content of memory entries you explicitly write or update.</li>
<li>OpenAI Terms of Use: https://openai.com/policies/terms-of-use</li>
