Smush – Image Optimization, Compression, Lazy Load, WebP & CDN vs AI Chatbot & Support Agent

You already know the old kind. A visitor asks a real question, the bot replies with a link to your FAQ page, and the visitor leaves. This is the other kind. Ultimo Bots puts a real AI support agent on your WordPress site. It answers from your own content, and then it does the actual work: books the meeting, looks up the order, saves the lead, and pulls you into the conversation when it matters. You describe it. It builds itself. There is no canvas to drag boxes around on. You open the builder and type what should happen, in your own words: “When someone asks about pricing, explain the plans and offer a demo call. If they want one, book it in my Cal.com and send the lead to HubSpot.” That is the entire build step. The agent is configured from that sentence. No code, no flowcharts, no developer, no agency. Changed your mind? Tell it. That is the edit step too. It doesn’t just answer. It acts. Connect the tools you already run, and the agent uses them mid-conversation: Books appointments in Cal.com, including reschedule and cancel, or hands over your Calendly link Takes payments and manages subscriptions through Stripe links. It can list, change, or cancel a subscription. Card details never enter the chat Saves and finds contacts in HubSpot, and subscribes visitors to Mailchimp with proper double opt-in Answers from your product catalog, with prices and stock, so “do you have this in blue” gets a real answer Calls your own API with your own credentials when you need something nobody else offers Captures leads inside the conversation and emails them to you the second they land Before the agent touches anything private, it emails the visitor a six-digit code and waits for it. Verified first, every time. One agent. Every channel. The same agent runs on your WordPress site, on a shareable chat link, in Facebook Messenger, Instagram DMs, Telegram, and Slack. You train it once and it shows up everywhere. Nothing to duplicate, nothing to keep in sync. It knows your business, and it will not invent Point it at your WordPress site and it reads it. Add PDFs, Word files, spreadsheets, Google Drive, OneDrive, Notion. Every answer is built from your material, and one click re-scans your site whenever it changes. When it does not know something, it says so and offers you instead. That one habit is why people trust it on a live site. It detects the language your visitor is writing in and answers in it. You configure nothing. You stay in control Write your rules in plain words and the agent holds them, even when a visitor pushes back. Watch conversations as they happen and jump in yourself with one click. The agent goes quiet the moment you start typing and picks up again when you leave. Get pinged in Slack, Telegram, Teams, or email whenever someone wants a human. Everything is included Every capability above is on every plan. Plans differ in volume, not in what your agent can do. No per-seat pricing, no per-resolution fees, no “contact sales”. Start with a free trial, then from $19 a month. Live in about two minutes Activate the plugin, answer a few questions, and your agent is on your site. That is the whole setup.
