i think you can just copy another text in the back of it with lower z-index and change the text of it

string.find(PlayerName:sub(1, Input:len()):lower(), Input:lower())

This will try to check if your user’s input matches the beginning of a player’s name.

Let’s say your PlayerName is “Foufou” and you type “fou”:

Input:len() --> 3 (length of input, "fou")

-- get the part of the string between indexes 1 and 3
PlayerName:sub(1, Input:len()) --> "Fou" since that's the first 3 letters of the player's name

-- then use :lower() to convert string to lowercase because "Fou" will not match "fou"

-- and finally use string.find() or :find() to check if input matches player name

Your code can look something like this:

local Players = game:GetService'Players'

TextBox:GetPropertyChangedSignal'Text':Connect(function()
	local Input = TextBox.Text:lower()
	
	for i, Player in pairs(Players:GetPlayers()) do
		if string.find(Player.Name:sub(1, Input:len()):lower(), Input) then
			AutoComplete.Text = Player.Name
		end
	end
end)

To actually display the autocompleted text on your text box like in the gif you can probably use the method from the reply above

you could also use string.match, that way we could allow stuff like " fou "
also it is GetPropertyChangedSignal not GetPropertyChanged

local Players = game:GetService("Players")

TextBox:GetPropertyChangedSignal("Text"):Connect(function()
    local Input = textbox.text:lower():match("^%s*(.-)%s*$")

    for _, Player in ipairs(Players:GetPlayers()) do
        if Player.Name:lower():match("^"..Input) then
            AutoComplete.Text = Player.Name
        end
    end
end)

Ty, and

print(("foufou"):match("^%s* fou %s*")) doesn’t seem to work

Also I don’t see a difference between find or match for this use case, you can use string patterns in string.find too

my bad I fixed it

CODE EDIT:
I realized it didn’t work again so I changed "%s*(.*)%s*" to "^%s*(.-)%s*$"
and that fixed it

I wasn’t talking about the use of string.find, I was talking about string.sub being used
