Code Humanizer Lua — Clean Up AI-Generated Lua Code (Guide)
AI is great at drafting Lua scripts, but the output is full of step comments, generic names and extra variables. Here is how to clean it up so it reads like the rest of your game code.
Heads up: the Code Humanizer tool currently supports Python, JavaScript, Java and C/C++. Lua support is on the roadmap — until then, this guide shows how to do the same clean-up by hand.
What gives AI-generated Lua away
Comments that restate the code — # Loop through each item above a for loop adds nothing a reader can't see
"Step 1:", "Step 2:" scaffolding — useful while the model was reasoning, noise once the code is in your repo
Naming that ignores your project — camelCase locals in a snake_case Python codebase, or the other way round in JavaScript
Needless temporaries — result = a + b followed immediately by return result
Docstrings that repeat the function name — """Calculate the total.""" on calculate_total()
Before and after
AI draft
-- Step 1: Define the function to give coins to the player
local function givePlayerCoins(player_obj, coin_amount)
-- Check if the player exists
if player_obj == nil then
return false
end
-- Step 2: Add the coins to the player's balance
local current_balance = player_obj.coins
local new_balance = current_balance + coin_amount
player_obj.coins = new_balance
return true
end
Cleaned up by hand
local function givePlayerCoins(player, amount)
if not player then
return false
end
player.coins = player.coins + amount
return true
end
A Lua clean-up checklist
Delete -- Step N comments and comments that restate the next line
Use one naming style per project — most Roblox code uses camelCase, many LÖVE projects use snake_case
Prefer if not x then over if x == nil then when false isn't a valid value
Inline variables that are used once right after they're assigned
Keep comments that explain game rules, tuning numbers or engine quirks
Working in Python, JavaScript, Java or C?

Code Humanizer is a readability and style tool. It isn't designed to hide who wrote code, and using it to break a course's academic integrity rules is against our Terms of Service. If your course allows AI assistance, comparing an AI draft with a cleaned-up version is a good way to learn idiomatic style.
