Plain-English definitions, no marketing speak.

The terms small-business operators keep running into when they evaluate AI receptionists, voice AI, dispatch software, and multi-tenant SaaS. Each definition is one paragraph, written the way we'd explain it to a friend.

AI receptionist

A software service that answers phone calls on behalf of a business using a conversational AI agent instead of a human. A modern AI receptionist can hold a real spoken conversation with a caller, capture details, book appointments to the operator's calendar, and route emergencies. TheChattyAI's Luna and Lucy are AI receptionists for English and Spanish callers respectively.

Voice AI

A class of AI systems that take spoken audio in and produce spoken audio out, in real time. Voice AI is distinct from chatbots (which read and write text) and IVR menus (which read recordings). TheChattyAI's production voice path is Twilio (telephony) plus Pipecat (orchestration) plus Google Gemini Live (the language model).

AI answering service

A subscription service that answers a business's phone calls using AI rather than a human virtual receptionist. Unlike traditional answering services, an AI answering service typically charges a flat monthly fee instead of per-call or per-minute, works 24/7 without after-hours surcharges, and can book appointments directly into the operator's calendar. See also: AI receptionist, voice AI.

AI dispatch(AI dispatch software)

Software that uses AI to assign incoming jobs to the right technician based on location, skill, schedule, and urgency. AI dispatch goes beyond a static rules engine: it can rebalance the day's schedule when a tech runs late, route emergencies, and surface conflicts before they cost revenue. TheChattyAI handles dispatch through its DispatchAgent, one of the fourteen specialist agents Aria coordinates.

Operations brain

A back-office orchestration layer that coordinates multiple specialized AI agents (dispatch, follow-up, recovery, scheduling, reviews, compliance) on behalf of a small business. Aria is TheChattyAI's operations brain. Owners interact with one app; Aria runs the fourteen specialist agents underneath.

Smart job card

A pre-filled brief that a technician sees before arriving at a job. A smart job card pulls together customer photos, the AI's diagnosis of the issue, property history, parts to bring, and likely duration. The goal is that the tech walks into the job already knowing what they're walking into. TheChattyAI generates smart job cards on the Professional plan.

Multi-tenant SaaS

A software architecture where one application instance serves many customers (tenants) with their data logically isolated from each other. The hard requirement is that no tenant can ever read another tenant's data. TheChattyAI enforces this at the database level using PostgreSQL row-level security with a per-request `app.tenant_id` context.

Row-level security(RLS)

A PostgreSQL feature that lets the database itself filter which rows a query can see, based on session context. With RLS enabled, even a query that forgets to filter by tenant cannot return another tenant's rows — the database refuses. RLS is the foundation of TheChattyAI's multi-tenant data isolation.

Append-only event ledger

A database table where rows can be inserted but cannot be updated or deleted, enforced by database triggers. Every customer-affecting action (call answered, booking made, SMS sent, agent decision) writes a row. The ledger is tamper-evident: the history can be reconstructed in detail and cannot be quietly rewritten.

HIPAA-capable

Infrastructure that meets the technical requirements to handle Protected Health Information (PHI) under HIPAA, including row-level isolation, audit logging, encryption in transit, and the ability to sign a Business Associate Agreement (BAA) with a covered entity. There is no such thing as "HIPAA-certified" software — there is only HIPAA-capable infrastructure plus a signed BAA. TheChattyAI's infrastructure is HIPAA-capable; we sign BAAs for medical workloads on request.

Business Associate Agreement(BAA)

A signed contract between a covered entity (a healthcare provider or insurer) and a vendor handling PHI on its behalf. A BAA is required by HIPAA before any PHI is shared with the vendor. TheChattyAI signs BAAs with covered-entity tenants before any PHI flows through the platform.

Bilingual AI receptionist

An AI receptionist that handles calls in two languages with native fluency, not via translation. TheChattyAI ships bilingual day one: Luna handles English callers, Lucy handles Spanish-speaking callers, and bilingual handoff covers callers who switch languages mid-call. Other languages are available on request.

Voice AI vs chatbot

A chatbot reads typed text and writes typed text. A voice AI hears spoken audio and speaks back in real time. Phone callers expect voice. A chatbot routed to a phone caller would feel jarring; a voice AI feels like a person picked up. TheChattyAI is voice AI on the phone path and chat-style on owner-facing surfaces.

Human in the loop

A design pattern where humans review or approve AI-generated actions before the action takes effect. TheChattyAI uses three oversight tiers: Tier 1 (auto, like appointment reminders), Tier 2 (supervised, like satisfaction follow-ups), and Tier 3 (human required, like batch outbound campaigns). The point is that the operator stays in control of the high-stakes choices.

Concurrent calls

The number of phone calls a system can handle simultaneously. A human receptionist handles one concurrent call. An AI receptionist handles unlimited (bounded only by cost). For home-service businesses with rush hours (Monday morning, post-storm Tuesday), concurrent capacity is the difference between answering everyone and missing the crowd.

Agentic SEO(AEO / GEO)

Search engine optimization for AI agents (ChatGPT, Claude, Perplexity, Gemini, Bing Chat, AI Overviews) instead of just for traditional Google rankings. Agentic SEO emphasizes structured data (Schema.org JSON-LD), an llms.txt handshake file, dense factual content with sources, and direct Q&A formatting that LLMs can lift into citations. Often called Answer Engine Optimization (AEO) or Generative Engine Optimization (GEO).

llms.txt

A plain-text file at the root of a website (`/llms.txt`) that tells AI agents what the site is about, how it should be cited, and where to find more detail. Conceptually similar to robots.txt or sitemap.xml, but for LLMs and AI agents. TheChattyAI's llms.txt is at https://thechattyai.com/llms.txt and a longer-form Markdown version at /llms-full.txt.

Append-only discipline

An engineering operating principle that says once a customer-affecting event is recorded, it cannot be edited or deleted — only added to. The principle prevents quiet history rewrites and gives operators (and auditors) a tamper-evident record of what the system did and why. TheChattyAI applies append-only discipline at the database level via UPDATE/DELETE triggers on the customer event ledger.
