Custom AI Chatbots
SMS and WhatsApp messaging that customers answer
SMS and WhatsApp assistants handle confirmations, reminders, and two way support in the channel customers read fastest. Lingows AI builds these assistants with consent capture, automatic opt out handling, and platform template compliance, because messaging rules are enforced by carriers and platforms rather than by preference.
01What this is
Messaging is a permission channel. Consent, opt out, and message classification are compliance requirements, and getting them wrong risks the sending number rather than just the campaign.
Message design differs from chat design. Replies are short, context persists across days, and a customer may respond to a reminder sent a week earlier. State has to be durable.
02Who this suits
Appointment based businesses
Operations where no shows are a measurable cost.
Delivery and service updates
Companies whose customers want status without calling.
WhatsApp first markets
Businesses serving regions where WhatsApp is the default channel.
03How it works
- Step 01
Capture consent explicitly
Record the opt in source and timestamp with the contact record.
- Step 02
Honor opt out automatically
Stop keywords are processed before any other logic, on every inbound message.
- Step 03
Keep durable conversation state
Replies arriving days later resume the correct thread with full context.
04Effort and timeline
| Item | Typical |
|---|---|
| Typical build | 3 to 6 weeks |
| Channels | SMS, MMS, WhatsApp Business |
| Consent | Captured with source and timestamp |
| Templates | Pre approved where the platform requires |
05Common failure modes
Messaging without consent
It risks carrier filtering, number suspension, and regulatory exposure.
Ignoring template rules
WhatsApp business initiated messages require approved templates and message windows.
Losing thread state
A reply that arrives after the session expires should not restart the conversation from zero.
FAQQuestions
Common questions
Do we need a dedicated phone number?
Yes for most production use. A dedicated number with proper registration protects deliverability and keeps automated traffic separate from staff messaging.
How is opt out handled?
Standard stop keywords are honored automatically on every inbound message, ahead of any other processing, and the suppression is recorded against the contact.

UPWhere this sits
SMS and WhatsApp is part of Custom AI Chatbots. The pillar page covers scope, delivery model, and the other capabilities in the set.
- Website Chat
Website AI chat answers visitor questions from a company's approved content, cites the source of each answer, and performs lookups in connected systems where that is permitted. Lingows AI builds web chat with an explicit scope, a visible path to a person, and transcript review as a standing practice.
- Voice AI
A voice AI agent answers an inbound phone call, understands the caller, handles the request where it can, and transfers to a person on request. Lingows AI builds voice agents for scheduling, status questions, and intake, with call recording, transcript logging, and an immediate path to a human.
- Internal Knowledge Assistants
An internal knowledge assistant answers staff questions from a company's own documentation, respecting the permissions each employee already holds. Lingows AI builds these assistants with permission aware retrieval, citations on every answer, and reporting on questions the documentation cannot answer.
