Prompt variables
Ask your AI assistant to add, change or remove the company facts your AI agent quotes on calls, such as your company name and offer.
What prompt variables are, asking the assistant to list them, adding a new one, updating a value, removing one, and checking that the prompt uses it.
Prompt variables are named facts about your business, like company_name, agent_name or offer. You write them once, and your prompts, intros and opening sentences refer to them in curly braces, for example {company_name}. When a call starts, Bigly swaps each placeholder for its value.
They're the same list you see on AI › Teach Your Bot › Prompt Variables in the app. Keeping facts here means you change the offer in one place instead of editing every prompt.
List our prompt variables. Change our offer to 20% off the first month. Add a variable called agent_name with the value Sarah. Remove the variable old_promo.
Before you start
- Connect your AI assistant to Bigly.
- You need permission to read prompt variables to see them, and permission to update them to add, change or remove one. Account owners and admins have both by default.
What the assistant reads
The assistant reads every variable on your account, as a list of names and values in alphabetical order.
Add or change variables
- Tell the assistant which variables you want and their values. You can include several in one request.
- The assistant shows a preview: each variable that would change, with its current value and its new value. A new variable shows no current value. Variables you mention with an unchanged value are left out.
- Confirm in the chat. The assistant saves the change and shows the updated list.
Variables you don't mention are left as they are. Changing one variable never removes the others.

Remove a variable
Ask the assistant to remove a variable by name. It confirms with you before removing it. Removing a variable that doesn't exist does nothing.
If a prompt or intro still contains {old_promo} after you remove that variable, the placeholder is not replaced, and nothing warns you. Ask the assistant to search your voice prompt and intros for it first.
Settings explained
| Field | What it is | Rules |
|---|---|---|
| Variable name | The name you put in curly braces in a prompt, such as company_name. | Letters, numbers and underscores only. No spaces. Up to 100 characters. |
| Value | The text that replaces the placeholder on a call. | Up to 1,000 characters. Can be empty. |
Limits and rules
- Each request needs at least one variable.
- A name with spaces, hyphens or other symbols is rejected, so use
agent_name, notagent nameoragent-name. - Names must match exactly.
{Company_Name}and{company_name}are different placeholders. - Placeholders are replaced as plain text with no checking. A typo in a prompt, like
{compnay_name}, is spoken or sent as written.
Check the result
To see a variable in context, ask for a call preview. It shows the final prompt and opening sentences with every placeholder filled in, so you can spot one that didn't resolve.
What you can't change here
- Contact details such as
{name}are filled in from each contact, not from prompt variables. Edit contacts in the app: see Contacts. - Built-in placeholders such as
{intro}and{working_hours}come from your intros and working hours. They aren't variables you can set here.
