AI Reply Agent

What you get

Taken from this product's own README (included in the download). A PHPGuru-developed product.

Included

• Start wizard (install.php): server check with a plain fix for every red line, database tables created for you, owner login (no default password), business details with a fictional example for hotels, clinics, coaching classes, salons, shops and restaurants, AI key test, "Try it" before going live, WhatsApp connection with token check (a temporary token is refused at go-live), number choice, automatic webhook connection with manual steps as a fallback, number registration, and a go-live check list
• Replies in the customer's language and script: English, Hindi (Devanagari) or Hinglish
• Answers only from your business details; anything not there goes to your team instead of being guessed
• Price check: a reply quoting a rupee amount that is not in your details is never sent
• Never confirms a booking, order, payment or refund itself: it collects the details and passes the chat on
• Declines unrelated requests politely (Meta allows business assistants, not general-purpose chatbots)
• Clinics: no medical advice; emergencies are told to call 112 and passed on at once
• Tells customers they are talking to an AI in the first reply of each day; HUMAN reaches a person; STOP and START switch automatic replies off and on
• Inbox for the owner and staff: "Needs you" list, conversation view with delivery ticks, replies within WhatsApp's 24-hour window (re-checked on the server), take over and hand back, automatic hand-back after 12 hours, photos, PDFs and voice notes opened from Meta on demand, auto-refresh
• Leads: name, what they want and when, noted from the conversation; CSV download for the owner
• Knowledge page with "Try a question"; weekly opening hours with a second time range for breaks
• Reply modes: always, only outside opening hours, or off
• Monthly AI spend cap, per-customer and overall reply limits, protection against reply loops with other bots
• Email alerts: customer needs a person (at most one per chat every 30 minutes), budget, connection problems
• Health page: connection status, typical reply time, AI cost per reply and by month, event log, and a support report to copy that never contains keys, tokens, messages or full customer numbers
• Team: staff logins for the inbox and leads; only the owner changes the setup
• Privacy: public privacy notice page (Meta asks for one), automatic deletion after 180 days (adjustable), delete a customer's data on request, opted-out numbers kept so STOP stays honoured
• Reliability: each WhatsApp message stored once, messages that arrive together answered once, at most one reply per batch even when Meta delivers twice, retries when the AI is busy, fallback message and hand-over when it fails, old redelivered messages sent to you instead of the AI
• Security: Meta's signature checked on every delivery, keys and tokens stored encrypted (AES-256-GCM), CSRF protection on every form, prepared statements, login lockout, data/ and code folders closed to the web

What it is not

It does not send broadcasts, bulk messages, marketing templates or messages to people who did not write to you first. It does not keep the number on the WhatsApp Business app at the same time (that needs a Meta Tech Provider). It does not take payments, confirm bookings, manage your calendar or connect to booking sites. It does not listen to voice notes (customers are asked to type), does not answer Instagram or Facebook Messenger, and runs one WhatsApp number per installation. It is not a general chatbot: it talks only about your business, as Meta's rules require.

Requirements & testing

PHP 8.1+ with mysqli, curl, openssl, json and mbstring (tested on PHP 8.5 with MySQL 8.0; the server check also passes on Hostinger with PHP 8.2 and MariaDB); MySQL 5.7+ or MariaDB 10.3+; https; outgoing HTTPS to graph.facebook.com and api.anthropic.com. Replies are fastest on LiteSpeed (Hostinger) or PHP-FPM hosting, which answer Meta first and prepare the reply right after. A cron job is optional (Settings -> WhatsApp shows the line to add). Bootstrap 5 CSS loads from the jsDelivr CDN; the app has no other dependency and needs no Composer.
