Common AI questions, answered in plain English

What is a large language model?

A large language model, or LLM, is the kind of AI behind chat assistants like ChatGPT, Claude and Gemini. It was trained on a vast amount of written text and learned to predict the next word in a sentence. Do that well enough, billions of times over, and you get something that can draft an email, summarise a report or answer a question in plain language.

What is the difference between ChatGPT, Claude and Gemini?

They are competing models from different companies: ChatGPT from OpenAI, Claude from Anthropic and Gemini from Google. They do broadly the same job, but each has different strengths, and they often give noticeably different answers to the same question. The practical move is not to pick one forever. It is to ask more than one when the answer matters, which is what BizChat and AI Consensus on BizWax.Ai are built to do.

Why does AI make things up?

Because it is predicting a likely answer, not looking one up. When it does not know, it can still produce something that sounds confident and is simply wrong. This is called a hallucination. The fixes are to give it the source material yourself, ask it to cite where each claim came from, and check anything important against a second model or a real source. Insight Lab answers from your own documents with citations for exactly this reason.

Is AI free to use?

Most AI assistants have a free tier with limits on how much you can use and which models you get. Heavier use means a paid plan or paying per use through an API key. Prices change often, so check each provider's own pricing page rather than trusting an old article.

What is an API key, and do I need one?

An API key is a password that lets software use an AI model on your account, and you pay the provider for what you use. You do not need one to chat with an assistant on its own website. You do need one when a tool runs AI on your behalf. On BizWax.Ai every tool runs on your own keys, so your usage is billed to you directly by the provider at their rates, with no markup in between.

Is it safe to put business data into AI?

It depends on the provider and the plan. Read the data policy for the service you use, in particular whether your inputs can be used to train future models and how long they are kept. As a rule, do not paste passwords, customer card details or anything you are legally required to protect into any AI tool. If a document is sensitive, strip the names out first.

Can AI replace my employees?

Rarely in full. What it replaces well is the first draft: the blank page, the tenth headline, the summary of a long document, the reply that needs polishing. That frees people for the parts that need judgement, relationships and accountability. Most small businesses get more out of AI by giving one person the output of three than by cutting anyone.

How do I write a good AI prompt?

Say who it is for, what you want, what good looks like, and what to avoid. Give an example if you have one. Vague prompts get vague answers. If you would rather not write four paragraphs every time, PromptLine takes your rough version and rebuilds it into a complete prompt.

Can I use AI-generated content for my business?

Generally yes, within each provider's terms of use, which you should read. Two cautions. In the United States, the Copyright Office has said that material produced purely by AI, without meaningful human authorship, cannot be copyrighted, so edit and add your own work to anything you want to own. And AI images of real people need their consent. This is general information, not legal advice.

Does Google penalise AI-written content?

Google's published position is that it rewards helpful, original content however it was produced, and penalises content made mainly to manipulate rankings, whoever or whatever wrote it. In practice, AI drafts that a person edits, fact-checks and adds real experience to do fine. Hundreds of unedited pages churned out to game search do not.

What can a small business actually use AI for today?

• Writing: headlines, product descriptions, emails and social posts, then turning one piece into many with Repurposer.
• Deciding: testing a business idea with the MOAT Evaluator or getting several models' view on a hard call with AI Consensus.
• Selling: practising a sales call with Sales Trainer before you take the real one.
• Visuals: finished ads with Ad Assembly and short product clips with Animize, without booking a designer.
• Research: asking questions of your own PDFs and getting cited answers with Insight Lab.

How do I start using AI in my business?

Pick one task you do every week that you dislike, and try AI on that alone for a month. Keep what works and drop what does not. Starting with one real job teaches you more than reading about every tool at once. If you want a set of tools built for business jobs behind one sign-in, you can create a free BizWax.Ai account and look around before you pay for anything.
