In 2026, OpenAI’s free API and http://Discord.js made this 10x easier. Server members will chat with AI 24/7 while you sleep peacefully.

Before Building Discord ChatGPT Bot Free – Requirements

For discord chatgpt bot free setup you need these 3 things:

Item | Why You Need It | Cost
Discord Account | To create the bot | Free
OpenAI API Key | ChatGPT’s brain | $5 free credit
Replit Account | Keep bot online 24/7 | Free

OpenAI gives every new account $5 free credit in 2026. That’s enough to run a discord chatgpt bot free for 3-4 months. If credits run out, make a new account with new Gmail.

Step 1: Create Discord Application – 2 Minutes

1. Open Discord Developer Portal: https://discord.com/developers/applications
2. Click New Application → Name it ChatGPT-Free-Bot
3. Go to Bot tab → Add Bot → Yes, do it!
4. Click Reset Token and copy the token. Don’t share this with anyone.
5. Under Privileged Gateway Intents turn ON 3 options: Presence, Server Members, Message Content

Important: In Bot Permissions tick Send Messages, Read Message History, Use Slash Commands.

Now go to OAuth2 → URL Generator. Select scopes bot and applications.commands. Copy the link below and invite the bot to your server.

Step 2: Get OpenAI Free API Key – 1 Minute

1. Open OpenAI Platform: https://platform.openai.com/api-keys
2. Click Create new secret key → Name it DiscordBot
3. Copy the key – it starts with sk-proj-xxxx

This API key makes your discord chatgpt bot free smart. $5 credit can process 2.5 million words. For a normal server, it lasts 6 months.

Step 3: Paste Code on Replit – 5 Minutes

1. Go to http://Replit.com → Create Repl → Select Python
2. Paste this code in main.py file:

import discord
import openai
import os
from discord.ext import commands

API Keys – Add in Replit Secrets

openai.api_key = os.environ[‘OPENAI_KEY’]
TOKEN = os.environ[‘DISCORD_TOKEN’]

intents = discord.Intents.default()
intents.message_content = True
bot = commands.Bot(command_prefix=’!’, intents=intents)

@bot.event
async def on_ready():
print(f'{bot.user} is now running!’)
await bot.tree.sync()

@bot.tree.command(name=”ask”, description=”Ask ChatGPT anything”)
async def ask(interaction: discord.Interaction, prompt: str):
await interaction.response.defer()

try:
    response = openai.chat.completions.create(
        model="gpt-4o-mini", # Cheapest model 2026
        messages=[{"role": "user", "content": prompt}],
        max_tokens=500
    )
    answer = response.choices[0].message.content
    await interaction.followup.send(f"**Question:** {prompt}\n\n**ChatGPT:** {answer}")
except Exception as e:
    await interaction.followup.send("Error: API limit reached or invalid key")

@bot.event
async def on_message(message):
if message.author == bot.user:
return

if bot.user.mentioned_in(message):
    prompt = message.content.replace(f'<@{bot.user.id}>', '').strip()
    response = openai.chat.completions.create(
        model="gpt-4o-mini",
        messages=[{"role": "user", "content": prompt}]
    )
    await message.channel.send(response.choices[0].message.content)

await bot.process_commands(message)

bot.run(TOKEN)

3. Open Secrets tab 🔒 → Create 2 keys:

• DISCORD_TOKEN = Paste Discord token
• OPENAI_KEY = Paste OpenAI key

Step 4: 24/7 Free Hosting for Bot – 2 Minutes

Replit stops bots on free plan. To keep your discord chatgpt bot free online 24/7:

1. Open Shell in Replit and type: pip install flask
2. Create new file keep_alive.py:

from flask import Flask
from threading import Thread

app = Flask(”)

@app.route(‘/’)
def home():
return “Bot is alive!”

def run():
app.run(host=’0.0.0.0′,port=8080)

def keep_alive():
t = Thread(target=run)
t.start()

3. In main.py add at top: from keep_alive import keep_alive and before bot.run(TOKEN) add keep_alive()
4. Make free account on http://UptimeRobot.com → Add New Monitor → Add your Replit web link. It will ping bot every 5 min.

Now your discord chatgpt bot free will never go offline.

Step 5: Test Bot on Discord

Go to Discord server and type: /ask prompt: Write a python code for hello world

Or mention the bot: @ChatGPT-Free-Bot What is the capital of Pakistan?

ChatGPT will reply in 2 seconds. Cool right?

3 Benefits of Discord ChatGPT Bot Free

1. Zero Cost: Replit + OpenAI $5 credit = 6 months free. You won’t find a cheaper discord chatgpt bot free than this.
2. Custom Commands: Add commands like !help, !image, !translate in code yourself.
3. Server Growth: People join servers because of AI bots. Engagement increases 300%.

Pro Tips: Make Bot Smarter in 2026

1. Change Model: gpt-4o-mini is cheapest. gpt-4o is smarter but expensive.
2. Add Memory: Store history in messages list so bot remembers previous messages.
3. Rate Limit: Add 1 user 5 msg/minute limit to prevent abuse.

Code:
from collections import defaultdict
import time
user_cooldowns = defaultdict(float)

Add this in on_message

if time.time() – user_cooldowns[message.author.id] < 12:
return
user_cooldowns[message.author.id] = time.time()

Common Errors And Fixes

Error | Fix
