Real reasoning
The model decides what to look up, which tool to call, and when to admit it does not know. No fallback to "I'm sorry, I didn't catch that."
WordPress AI chatbot BYOK
PressBot is the WordPress AI chatbot plugin built around a real model, not a regex tree. Bring your own API key from Anthropic, OpenAI, Google, or DeepSeek and PressBot routes every conversation to the model you picked. The agent reasons, calls typed tools, retrieves passages, and admits when it does not know. DeepSeek is the budget public-chat option; the admin agent runs on Anthropic, OpenAI, or Google.
Why an AI chatbot beats a FAQ matcher
The dominant "AI chatbot" plugins in 2026 are still regex trees with a model called for the final paraphrase. PressBot is a real agent driven by the model end-to-end — the conversation, the routing, the tool calls, the citations, all of it.
The model decides what to look up, which tool to call, and when to admit it does not know. No fallback to "I'm sorry, I didn't catch that."
The bot reaches for real tools — product lookup, shipping zones, knowledge base, refund policy, ACF fields — instead of paraphrasing the model's stale memory.
Answers reach for your real content first — posts, products, FAQs, ACF fields, or an external retriever you connect — and the visitor sees clickable citations next to the reply. Not a paraphrase.
Tokens arrive on the page as the model produces them. Accents, CJK, emoji all survive the chunked encoding intact — the visitor sees a typing answer, not a 3-second blank.
Which AI model is right for your WordPress site
PressBot supports the major labs side by side. The right choice depends on what your visitors actually ask, how much you want to spend, and how fast the chat needs to feel. Switch any time without reinstalling.

Inside the chat
When a visitor types a question, PressBot does not match keywords against a flowchart. It hands the message to the model, which parses intent, picks tools, calls them, weighs the results, and writes an answer it can defend. The trace shows the steps in real time.
Native integrations with the plugins you already run
PressBot ships dedicated tool sets for the plugins that touch the most content surfaces. The agent reads and writes through their proper APIs — not screen-scrapes — so updates land cleanly inside the same Yoast / ACF / Woo data your site already uses.
The Pro admin agent ships four Yoast-specific tools (yoast_get_post_meta, yoast_audit_posts, yoast_suggest_post_meta, yoast_update_post_meta) for site-level metadata workflows. Works with Yoast Free and Premium.
Read field groups, schemas, and values; audit empty answer-ready fields like FAQ blocks, spec tables, and schema fields; and update through a schema-validated flow. Works with ACF Free and Pro.

Quick answers to what most site owners ask before they wire an AI chatbot into their WordPress install.
For most sites the answer is the cheap-tier model from whichever provider you already use — Claude Haiku 4.5, Gemini 2.5 Flash (or Flash Lite), GPT-5.4 mini, or DeepSeek V4 Flash. They cost a tiny fraction of a cent per reply, handle tool calls cleanly, and feel fast in the widget.
For sites where the bot does heavier reasoning — product comparisons, multi-step support, content generation — step up to a mid-tier model (Claude Sonnet 4.6, GPT-5.4, or Gemini 2.5 Pro). Reserve the flagship Opus 4.6 / GPT-5.4 Pro for the admin agent in Pro, not the visitor chat.
Yes — that is the BYOK design. You create an account directly with Anthropic, OpenAI, Google, or DeepSeek, paste the key into PressBot, and the WordPress AI chatbot talks to that account. We do not resell tokens, we do not charge per message, and we never see your conversations.
Yes, anytime, in two clicks. PressBot stores a separate key slot for each provider. You can run a cheap Flash/Haiku class model for the public chat and a flagship Opus 4.6 or GPT-5.4 Pro model for the admin agent, and swap either one the day a better model ships. No re-install, no re-train. DeepSeek is the exception: it is wired up for the public chatbot only, so the admin agent always runs on one of Anthropic, OpenAI, or Google.
PressBot grounds answers in your real content (posts, products, FAQs, ACF fields, optional external corpus) through typed tool calls. When the retriever returns nothing or scores below threshold, the bot tells the visitor so — it does not invent a passage to fill the gap. That is the single biggest hallucination defense.
You can also see the full reasoning trace per conversation in WP admin and adjust per-tool guardrails (cap result count, require citation, etc.).
Yes, all three are first-class integrations. The PressBot Pro admin agent calls them through their proper PHP / REST APIs (not screen-scraping the admin UI): four Yoast tools for site-level metadata, seven ACF tools for field reads / audits / validated writes, and ten WooCommerce tools across orders, products, coupons, customers, and sales analytics. See the Yoast page, ACF page, and WooCommerce page for the per-plugin breakdowns. Separately, PressBot's own AI Visibility Opportunity Engine runs GEO / AEO audits independent of any third-party SEO plugin.
Not today. The visitor chatbot is text in, text out. The Pro admin agent uses model vision to describe images already on the site (through GPT or Gemini vision endpoints), but visitor-facing image uploads in the public chat are not wired up yet. If that lands, it will be a feature note on the changelog.
Three architectural choices that hold across our positioning. BYOK: PressBot routes through your own Anthropic, OpenAI, Google, or DeepSeek key — we do not resell tokens. Real tool-calling agent: the model decides which tools to call (search, retrieval, WP/Woo functions), it is not a flowchart that calls the model only for paraphrasing. Self-hosted: transcripts live in your WordPress database, not on an external dashboard. Specific competitor pricing and feature matrices live on the per-vendor comparison pages.

Yes for the visitor surface — the free tier covers the entire public AI chatbot with no per-message fees and no trial wall. You only pay your AI provider, at their listed API rate, with no markup. See the free WordPress chatbot page for the BYOK math.
