🎓 Train Your Chatbot on Your Own Content

What makes this chatbot powerful is its ability to learn from your website.

You can train your chatbot using:

📘 Pages and posts
🛒 WooCommerce products (prices, stock, SKU — always up to date)
❓ FAQs

And your visitors can send files directly in the chat:

📸 Photos & screenshots — the AI literally sees the image using vision AI
📄 PDF documents — text is extracted automatically and analyzed in context

Imagine a customer sending a photo of their broken appliance, or uploading a contract for the AI to summarize. That’s not future tech — it works today.

This means your chatbot gives accurate answers based on YOUR business — not generic internet responses.

Your visitors talk to a specialized chatbot, not a random AI. Genuine AI chat powered by your own knowledge base.

External Services / Data Disclosure

This plugin can connect to the following third‑party APIs depending on which features you enable. You (the site owner) must supply the API keys. No keys are bundled and no traffic is proxied through a vendor server controlled by this plugin author.

1. OpenAI

Used for: chat completions / responses, embeddings (context indexing), moderation (safety checks).

Endpoints used (HTTPS):
* https://api.openai.com/v1/chat/completions (legacy Chat Completions)
* https://api.openai.com/v1/responses (Responses API – new unified endpoint if configured)
* https://api.openai.com/v1/embeddings (document/post/PDF embedding + wizard indexing)
* https://api.openai.com/v1/moderations (content moderation)

Data Sent:
* User prompt text (per message) and limited conversation history (trimmed for token control)
* System / policy instructions (security + privacy policy + bot instructions)
* Optional retrieved context snippets (only the selected top‑N chunks or page excerpt – never the full original document)
* Embedding requests: raw chunk text produced from your site’s content or uploaded PDFs
* Moderation: only the user prompt text (not the entire history)

Data Retention (Your Server):
* Conversation log rows (if logging enabled) including user prompt, model reply, timestamps, bot slug, session id, optional user id. IP (binary) only stored when per‑IP limits are turned on. Disable logging to stop storing new rows.
* Embeddings table stores numeric vectors generated from your content (not reversible plaintext) plus the original chunk text for retrieval.

Recommendations:
* Update your privacy policy to disclose sending user prompts and limited site content to OpenAI for processing.
* Disable logging or periodically purge if you process personal data.

Legal / Docs:
* Terms: https://openai.com/policies/terms-of-use
* Privacy: https://openai.com/policies/privacy-policy
* Usage Policies: https://openai.com/policies/usage-policies

Opt‑Out / Control:
* Remove the OpenAI API key in Settings to stop all OpenAI calls (bots will refuse to answer).
* Disable conversation logging.
* Limit context ingestion to non‑sensitive pages.

2. Anthropic (Claude)

Used for: alternative chat completions via Claude models (messages API) when a bot provider is set to Anthropic/Claude.

Endpoint used (HTTPS):
* https://api.anthropic.com/v1/messages

Data Sent:
* A rewritten message array: system instructions + user prompt + condensed prior turns (trimmed) + optional retrieved context snippets.
* Model identifier, max tokens / temperature style parameters.

Headers:
* x-api-key (your key) and anthropic-version (currently 2023-06-01 set in code).

Retention (Your Server):
* Same as OpenAI notes for conversation logging (the provider choice does not change local storage schema).

Legal / Docs:
* Terms: https://www.anthropic.com/legal/terms-of-service
* Privacy: https://www.anthropic.com/legal/privacy
* Usage Policy: https://www.anthropic.com/legal/aup

Opt‑Out / Control:
* Leave the Claude API key blank; those bots will fallback/refuse if provider requires it.
* Switch provider per bot back to OpenAI.

3. Pinecone (Optional Remote Vector Store)

Only used if you explicitly create a Context with remote type “Pinecone”. Local context mode (default) never contacts Pinecone.

Endpoint Pattern:
* Region/index specific HTTPS endpoints you enter (example placeholder: https://controller.pinecone.io and index query/upsert endpoints under *.pinecone.io). The plugin validates host against an allowlist containing pinecone.io (filter extendable).

Used For:
* Upserting embeddings (during context indexing / syncing)
* Querying similar vectors when answering a question in that context.

Data Sent:
* Vectors (embedding arrays) and associated metadata (post/page IDs, titles, short chunk text) for upsert.
* Query: the embedding vector of the user question + top‑K request.

Retention:
* Stored inside your Pinecone project (not on this plugin server). Local DB still keeps minimal reference metadata if you mix modes.

Legal / Docs:
* Terms: https://www.pinecone.io/terms/
* Privacy: https://www.pinecone.io/privacy/
* Security: https://www.pinecone.io/security/

Opt‑Out / Control:
* Do not configure a remote Pinecone context; use local mode or page mode instead.
* Delete the remote context to stop future upserts/queries.

4. Google Gemini (Optional AI Provider)

Used for: alternative chat completions via Google Gemini models when a bot provider is set to Google/Gemini.

Endpoint used (HTTPS):
* https://generativelanguage.googleapis.com/v1beta/models/{model}:generateContent

Data Sent:
* System instructions + user prompt + condensed prior turns (trimmed) + optional retrieved context snippets.
* Model identifier and generation configuration parameters.

Headers:
* API key passed as URL parameter (key=).

Retention (Your Server):
* Same as OpenAI notes for conversation logging.

Legal / Docs:
* Terms: https://ai.google.dev/gemini-api/terms
* Privacy: https://policies.google.com/privacy
* Usage Policy: https://ai.google.dev/gemini-api/terms

Opt‑Out / Control:
* Leave the Gemini API key blank; those bots will fallback/refuse if provider requires it.
* Switch provider per bot to OpenAI or Claude.

5. Freemius SDK (Licensing & Analytics)

This plugin uses the Freemius SDK for license activation, update delivery, and anonymous usage analytics (opt-in).

Endpoints used (HTTPS):
* https://api.freemius.com (license checks, updates, analytics)
