Matrix ChatGPT Bot
Note: This is unmaintained. You should use Baibot instead of this project.
Talk to ChatGPT via any Matrix client!
A Matrix bot that uses waylaidwanderer/node-chatgpt-api to access the official ChatGPT API.
Warning for users upgrading from version 2.x
OpenAI released the official API for ChatGPT. Thus, we no longer have to use any older models or any models which kept on being turned off by OpenAI. This means the bot is now way more stable and way faster. However, please note: The usage of the API is no longer free. If you use this bot, your OpenAI account will be charged! You might want to limit your budget in your account using the OpenAI website.
You need to remove the CHATGPT_MODEL
variable from your environment, if you changed the value.
Usage
- Create a room
- Add the bot
- Start chatting.
Features
- Shows typing indicator as ChatGPT is thinking!
- Supports encryption
- Stores context for ChatGPT conversations
Configure
Create a copy of the example .env
file
cp .env.example .env
Adjust all required settings in the .env
file before running. Optional settings can also be adjusted later.
Prerequsistes
Matrix
- You need a Matrix account on Matrix.org (or any other server) for the bot user.
- By default, anyone that knows the name of your bot can invite it to rooms or chat with it.
- Restrict access with
MATRIX_BLACKLIST
orMATRIX_WHITELIST
- Restrict access with
MATRIX_ROOM_BLACKLIST
orMATRIX_ROOM_WHITELIST
- When using a self-hosted setup, you could wildcard all your users with
MATRIX_WHITELIST=:yourhomeserver.example
.
OpenAI / ChatGPT
- You need to have an account at openai.com. Please note that the usage of the ChatGPT-API is not free.
- Create a API Key. Then, set
OPENAI_API_KEY
in your.env
file - You can change the chat-model by setting the
CHATGPT_API_MODEL
in your.env
file. ChatGPT is thegpt-3.5-turbo
-model which is the default. Please note that depending on the model your OpenAI account will be charged. - You can change the API-URL to use another base than the official OpenAI-endpoint. To do so, change the
CHATGPT_REVERSE_PROXY
in the.env
file.
Setup
- Set
MATRIX_BOT_USERNAME
- Set
MATRIX_BOT_PASSWORD
(you can remove this later if you want) - Run the app using one of the methods below.
- Copy
MATRIX_ACCESS_TOKEN
from the output. - Set
MATRIX_ACCESS_TOKEN
, you can now removeMATRIX_BOT_PASSWORD
.
Note: Doing any of the following can cause issues with encryption later on:
- Using this token with any other client.
- Using an access token extracted via Element.
- Deleting the storage folder.
- Switching between environments (e.g. Docker or no Docker)
Run
There are multiple ways to run this bot. The easiest way is to run it within docker.
with Docker
This is the recommended way to run this project. It will use the latest stable release.
docker run -it -v storage:/storage --env-file=./.env --name matrix-chatgpt-bot ghcr.io/matrixgpt/matrix-chatgpt-bot:latest
or to build locally from the latest unstable release (only do this if you have a good reason):
docker build . -t matrix-chatgpt-bot
docker run -it -v storage:/storage --env-file=./.env --name matrix-chatgpt-bot matrix-chatgpt-bot
Note: Without -it flags in the command above you won't be able to stop the container using Ctrl-C
Note: In order to see the output of your console you need to run docker logs matrix-chatgpt-bot
with Docker Compose
If you prefer you can use a docker-compose file. Copy the content below and save it in a file named docker-compose.yml
. Either with a self-build image (run docker build . -t matrix-chatgpt-bot
from your local git repo location) or with the latest stable pre-built release from this repo (the recommended way).
The script will look for the .env
file in the same folder as the docker-compose.yml
. The key storage folder storage
will be created in the same folder as well. Adjust the locations to your needs.
version: '3.7'
services:
matrix-chatgpt-bot:
container_name: matrix-chatgpt-bot
image: ghcr.io/matrixgpt/matrix-chatgpt-bot:latest ## change to "matrix-chatgpt-bot" if you want to use your self-build image
volumes:
- ./storage:/storage
env_file:
- ./.env
without Docker
Important: It is strongly recommended to run this package under Docker to not need to install various dependencies manually.
Nevertheless, you can also run it by using the package manager yarn (get it via apt install -y yarn
). You might also need to have a newer version of Node.js and other missing packages.
yarn
yarn build
yarn start
in Development
You only need to do this if you want to contribute code to this package.
- Run
yarn

Good to know
- By default "storage"-folder contains all your encryption keys. If you delete it, you will loose access to all your encrypted messages.
- You can use a Keyv storage backend for persistence if you prefer (advanced).
- The bot uses threads by default, to keep the context you should reply to this thread or the bot will think its a new conversation. "Threads" were previously experimental, you may need to activate them in your client's settings (e.g. in Element in the "lab"-section).
- There is support to set the context to work at either the:
- room level
- thread level
- both (threads fork the conversation from the main room)
FAQ
I get "[Error: decryption failed because the room key is missing]"
Encryption works great with this package but can sometimes be a bit sensitive. Following steps can help to solve the "encryption" error
- Don't use a
MATRIX_ACCESS_TOKEN
extracted via Element-App, use the generated token from the bot based on yourMATRIX_BOT_USERNAME
&MATRIX_BOT_PASSWORD
set in theenv
file. It will be visible in the console at start up if theMATRIX_ACCESS_TOKEN
is not already set:
- Remove the
MATRIX_ACCESS_TOKEN
from theenv
file and make sureMATRIX_BOT_USERNAME
&MATRIX_BOT_PASSWORD
are set - Re-run the bot
- Copy the token from console output to your
env
file - Restart the bot again.
- If all fails, you can always reset your key storage. It's important to exercise all of the following steps, because any remaining data could lead to the next encryption error. Once everything is working, make sure to not touch the "storage" folder anymore:
- Stop the bot
- Delete the "storage" folder
- Delete all user data for the matrix bot account (e.g. use Synapse-Admin) or create a fresh bot user account (you can then skip step 4)
- Log into your bot account (e.g. via Element) and log out of all sessions
- Verify the correctness of your
env
file and then run the bot setup again (e.g. viadocker-compose up
if you use docker-compose).
I want to chat with the bot without dealing with encryption problems
- Set
MATRIX_ENCRYPTION=false
in your env-file and restart the bot. If it previously was running with encryption switched on, you need to create a new room with the bot as encryption can't be switched off once it was activated.
I get "{ errcode: 'M_NOT_FOUND', error: 'Event not found.' }"
- So far, its not known to cause issues, you can safely ignore it.
How do I know that the bot is running succesfully?
Once the bot has started succesfully, it will output the following information to your console.
[INFO] [index] Starting bot...
[INFO] [MatrixClientLite] End-to-end encryption enabled
## this depends on your setup[INFO] [index] Bot started!
I use Docker but I don't see any console output
You most likely need to view the logs by running docker logs matrix-chatgpt-bot
How to set the temperature
Set the temperature by using CHATGPT_TEMPERATURE in your .env file. The default is 0.8.
Here are some guidelines for setting the temperature:
Temperature Values | Appropriate Tasks | Examples |
---|---|---|
Below 0.5 (low) | Tasks requiring a single correct answer or predictable output | Programming |
0.5-0.9 (medium) | Tasks needing somewhat varied and creative content grounded in reality | E-mail response |
Above 0.9 (high) | Tasks requiring more creative and unpredictable output | Story writing |
The response I receive is excessively long and gets truncated. Unlike in ChatGPT, my matrix does not have a "Continue generating" button.
You can simply write continue
to prompt the bot to continue from its previous answer.
