The words, explained plainly.

Short, straight definitions of the AI, app and automation terms that come up when you build software or add AI to a business.

A2P 10DLC

A2P 10DLC is the US registration system that businesses must complete to send application-to-person text messages from standard 10-digit phone numbers.

Without registration, carriers can filter or block your business texts.

AI agent

An AI agent is software that uses a language model to decide what to do next and then takes actions with tools, like booking a meeting, updating a CRM or sending a text, instead of only replying with words.

A chatbot answers. An agent answers and then does something about it, within the limits you set.

What is an AI agent?

AI answering service

An AI answering service is a voice agent that covers a business phone after hours, on weekends or when every line is busy, and can book, answer and escalate instead of only taking messages.

Most businesses forward calls to it only when the office does not pick up.

AI appointment setter

An AI appointment setter is a voice or text agent that contacts leads or answers inquiries and books them straight into a calendar.

It works best when it reaches new leads within minutes and sends reminders before the appointment.

AI appointment setter guide

AI call center

An AI call center uses voice agents to handle inbound and outbound calls at scale, with people stepping in for calls that need judgment.

For small and mid-size businesses it usually means answering every call, following up on leads and confirming appointments without adding seats.

AI call center guide

AI chatbot

An AI chatbot is a text assistant, usually on a website, in an app or over SMS, that answers questions and completes tasks using a language model trained or grounded on your business information.

Good ones are limited to approved information and hand off to a person when they are unsure.

AI chatbots for websites

AI consulting

AI consulting is advice on where AI can save time or bring in revenue for a business, which tools fit and how to roll them out.

The useful kind ends with working software and measured results, not just a strategy deck.

AI receptionist

An AI receptionist is a voice agent that answers a business phone line, handles common questions, books or reschedules appointments and passes complex calls to a person.

Unlike voicemail or a basic phone menu, it actually resolves the call, and it can answer many calls at once, around the clock.

AI video ad

An AI video ad is a marketing video produced partly or mostly with generative AI tools for visuals, voice or editing, directed and finished by people.

It makes it practical to test many variations quickly.

AI video production

AI voice agent

An AI voice agent is software that holds a natural phone conversation, understands what the caller wants and takes an action such as booking, qualifying or updating a CRM.

Used for inbound calls it works as an AI receptionist. Used for outbound calls it can follow up with leads who asked to be contacted.

API

An API (application programming interface) is a defined way for one piece of software to request data or actions from another.

If a tool has an API, it can almost always be connected to your other systems.

Integrations

App Store Connect

App Store Connect is Apple's web portal for submitting iOS apps, managing listings, screenshots, privacy details, TestFlight testing and releases.

Using it requires a paid Apple Developer Program membership.

How to publish an app

App Store Guideline 4.2

Guideline 4.2 is Apple's minimum functionality rule, which rejects apps that are little more than a repackaged website.

Wrapped web apps pass when they add real app value, like push notifications, offline features or native navigation.

App Store rejection reasons

App Store Optimization (ASO)

App Store Optimization is the work of improving an app listing, including title, keywords, screenshots and ratings, so it shows up in store search and converts more visitors into downloads.

It is SEO for the App Store and Google Play.

App Store Optimization guide

Base44

Base44 is an AI app builder that turns plain-English descriptions into working web apps with a database, logins and hosting built in, and it can also produce files for the App Store and Google Play.

Base44 was acquired by Wix in 2025.

What is Base44?

Business Associate Agreement (BAA)

A Business Associate Agreement is a HIPAA contract that a healthcare provider signs with vendors that handle protected health information on its behalf.

Any voice, phone or AI vendor that touches patient information for a covered practice should sign one.

AI receptionist for medical offices

Business automation

Business automation is using software to handle repetitive work, like follow-ups, data entry, reminders and routing, so it happens reliably without someone doing it by hand.

AI extends automation to tasks that need understanding, like answering a question or qualifying a lead.

AI automation agency

Client portal

A client portal is a secure website or app where a business's clients log in to see their projects, documents, invoices, messages or bookings.

Portals replace scattered email threads with one place clients actually use.

Web app development

Closed testing (Google Play)

Closed testing is a Google Play release track where an invited group of testers uses your app before it goes public.

Newer personal developer accounts must run a closed test with a minimum number of testers for a set period before they can publish to production.

Google Play Console guide

Conversational AI

Conversational AI is technology that understands and responds to people in natural language, in text or voice, rather than through fixed menus or keyword rules.

For businesses it usually shows up as website chatbots, SMS assistants and voice agents.

Conversational AI and chatbots

CRM

A CRM (customer relationship management system) is software that keeps track of your contacts, leads, deals, conversations and follow-ups in one place.

Connecting your phone, forms and calendar to the CRM is what makes automation possible.

Google Play Console

Google Play Console is Google's portal for publishing Android apps, managing store listings, testing tracks, policy forms and releases.

New personal developer accounts must run a closed test before publishing to production.

How to publish an app

Hallucination

A hallucination is when an AI states something that sounds confident but is wrong or made up.

Grounding answers in your own data, limiting scope and adding human handoff are the standard ways to reduce it.

IVR (interactive voice response)

IVR is the traditional "press 1 for sales" phone menu that routes callers using keypad choices or simple voice commands.

AI voice agents replace rigid menus with a normal conversation.

Voice AI

Large language model (LLM)

A large language model is an AI model trained on huge amounts of text that can understand and generate language, and it powers most modern chatbots and voice agents.

Examples include the models behind ChatGPT, Claude and Gemini.

Latency (voice AI)

Latency is the delay between when a caller stops talking and when the voice agent starts responding.

Lower latency makes a conversation feel natural, and long pauses are the main thing that makes a voice agent feel robotic.

Comparing voice AI platforms

Make

Make, formerly Integromat, is a visual automation platform that builds multi-step scenarios between apps and is usually priced by operations or credits.

It sits between Zapier and n8n in flexibility and learning curve.

n8n vs Zapier vs Make

Missed call text back

Missed call text back is an automation that sends an SMS to anyone whose call goes unanswered, so the conversation continues by text instead of being lost.

It works best paired with an AI receptionist that answers the call in the first place.

Missed call text back guide

MVP (minimum viable product)

An MVP is the smallest version of a product that real users can use and that tests whether the idea is worth building further.

A good MVP is small in scope but works properly for what it does.

MVP development guide

n8n

n8n is a workflow automation tool that connects apps and APIs with visual workflows, and it can be self-hosted or used in the cloud.

It is popular for AI agent workflows because it lets you mix plain logic, code and language model steps.

What is n8n?

Native app

A native app is an application built for a specific platform, like iOS or Android, and installed from that platform's app store.

Native apps get full access to device features such as push notifications, the camera and offline storage.

Mobile app development

No-code

No-code tools let people build apps, websites or automations through visual editors or plain language instead of writing code.

Low-code tools are similar but expect some code for advanced features.

Best AI app builders

Progressive web app (PWA)

A progressive web app is a website that can be installed to a phone's home screen and behave somewhat like an app, without going through an app store.

PWAs are cheaper to ship but have more limits on iPhone than native apps.

PWA vs native app

Retrieval-augmented generation (RAG)

Retrieval-augmented generation is a technique where an AI looks up relevant documents, like your FAQs or policies, before answering, so its replies are grounded in your actual information.

It is one of the main ways to keep a business chatbot accurate.

Row-level security (RLS)

Row-level security is a database rule that controls which records each user is allowed to see or change, so customers only ever see their own data.

Getting these rules right is one of the most important steps in taking an AI-built app to production.

Base44 security guide

Speed to lead

Speed to lead is how quickly a business responds to a new inquiry, measured from the moment the lead comes in to the first real contact.

Research consistently shows that responding in minutes rather than hours makes a big difference in whether a lead converts.

Speed to lead guide

TCPA

The Telephone Consumer Protection Act is a US law that restricts automated calls and texts, and it requires consent before many kinds of marketing calls and messages.

In 2024 the FCC confirmed that AI-generated voices count as artificial voices under the TCPA. This is not legal advice.

AI calling and the law

TestFlight

TestFlight is Apple's beta testing service that lets you send pre-release builds of an iOS app to testers before it goes live in the App Store.

It is the standard way to test an iPhone app with real users before review.

Vibe coding

Vibe coding is building software by describing what you want to an AI and iterating on the result, rather than writing the code line by line yourself.

The term was coined by Andrej Karpathy in early 2025. It is fast for prototypes, and production apps still need security, data and testing work.

Vibe coding guide

Webhook

A webhook is an automatic message one app sends to another the moment something happens, like a form submission or a booked appointment.

Webhooks are the simplest way to trigger automations in real time.

Workflow automation

Workflow automation means letting software carry out the repeatable steps of a process, like moving a lead into a CRM, sending a follow-up and creating a task, without someone doing it by hand.

Adding AI steps lets a workflow read messages, sort requests and write replies, not just move data.

AI workflow automation

Zapier

Zapier is a hosted automation service that connects thousands of apps with triggers and actions, usually priced by the number of tasks you run.

It is the easiest place to start, and it can get expensive at high volume.
