Myth vs fact

Common beliefs about AI tools, and what the lessons and the glossary actually show.

Myth: A 200 Status Means the Workflow Is Done

Myth vs fact: a 200 only means the server accepted the request. A webhook can answer before the workflow has done anything at all.

Myth vs fact One graphic

Myth: A Business ChatGPT Plan Makes PII Safe to Paste

Myth vs fact: a business plan can reduce risk, but it doesn't override industry rules or client agreements. Leave out what the task doesn't need.

Myth vs fact One graphic

Myth: An AI Model Looks Things Up Before It Answers

Myth vs fact: by default a large language model answers from its training plus your prompt. Web search or file lookup is a separate step.

Myth vs fact One graphic

Myth: ChatGPT Already Knows My Business

Myth vs fact: ChatGPT knows the current chat, its general training and what you set up. Your current prices and policies still have to come from you.

Myth vs fact One graphic

Myth: Removing Names Is Enough to Stop AI Bias

Myth vs fact: hiding names helps, but bias comes through other details. Job-related criteria and evidence for each score do more.

Myth vs fact One graphic

Myth: Telling an AI Agent Not to Send Email Is Enough

Myth vs fact: a "drafts only" rule in the system prompt helps, but choosing the Draft resource in the Gmail tool is what makes sending impossible.

Myth vs fact One graphic

Myth: There Is a Magic Wording for ChatGPT Prompts

Myth vs fact: "act as an expert" helps far less than plain facts. Say what you need, give the details only you know and say how it should look.

Myth vs fact One graphic

Myth: Turning Off Training Makes ChatGPT Private

Myth vs fact: turning off training stops chats being used to improve models, but they are still processed and stored. Remove details you don't need.

Mistakes to avoid

One mistake the lessons are built to prevent, and what to do instead.

Mistake to Avoid: A Soft Yes When You Mean No

A visual tip for customer emails: AI drafts blur a no into "we'll do our best." Say no early, give one reason and a real alternative.

Mistake to avoid One graphic

Mistake to Avoid: Letting AI Invent Expense Categories

A visual tip for bookkeepers: give an AI agent a fixed list of categories plus Needs Review, so it never makes up a category name.

Mistake to avoid One graphic

Mistake to Avoid: Not Setting a Length in Your Prompt

A visual tip: say the length in the Format part of your prompt, like under 120 words, instead of trimming a 300-word reply by hand.

Mistake to avoid One graphic

Mistake to Avoid: Pasting a Webhook URL into Your Page

A visual tip: don't paste your n8n webhook URL into the page. Store it as a Lovable secret so it stays out of the source and is easy to change.

Mistake to avoid One graphic

Mistake to Avoid: Promising a Date Nobody Confirmed

A visual tip for late orders: give the AI only timing you have confirmed. If there is no date yet, say when you will update the customer.

Mistake to avoid One graphic

Mistake to Avoid: Scheduling Before Setting the Timezone

A visual tip for n8n schedules: set the workflow timezone before the schedule, so 7am means 7am where your business is.

Mistake to avoid One graphic

Mistake to Avoid: Sending Every Job Email to One Address

A visual tip for n8n and Gmail: make the To field an expression for the Tech Email column, written in square brackets because of the space.

Mistake to avoid One graphic

Mistake to Avoid: Testing an Unpublished n8n Workflow

A visual tip: an n8n production webhook URL only works once the workflow is published. Publish first, then copy the URL into your app.
