Chatty - A new front-end to ChatGPT

Chatty Server (chatty-server)

Note: You can find the most recent release notes here.

Chatty Server is a client interface for GPT-3.5 and GPT-4. It allows you to use GPT-4 for many tasks. For that, it allows you to store "prompts" (in folders), that allows you to quickly have GPT-4 analyze your text in a certain way and respond to you.

I've created a bunch of prompts to start with. These are automatically imported as factory prompts. On the prompt line, type / and search for a prompt and press enter.

For example, to summarize a mail thread efficiently, select the entire mail text in your mail client, click on the input box in Chatty, press /, type mail and select Summarize mail.

Paste the text in the dialog and press Enter. This produces the full prompt you for GPT-4. Just press Enter again to execute it.

Using a browser or Chatty

Chatty Server is a web-based which can be accessed by browser. It is deployed on a server with a basepath of / (for the actual value, check config.js). So, if you deploy it on https://myserver.com, you can access it at https://myserver.com/chatty.

There a thin client for Mac called Chatty that you may want to check out. It is a thin wrapper around a web view, that allows you to use Chatty Server as a stand-alone application on a Mac.

If you like it, or if you have comments, reach out to me.

Happy chatting!

Is it safe to use?

The chatty-server can run on any server, but it tries to be as secure as possible. It does not store or log any of the prompts, conversations, API keys or other secrets on the server.

All sensitive information is kept client side and stored in browser 'local storage'.

Conversations are sent (through SSL) to the server, of course, but not logged or persisted server-side. (Exception: The server logs may contain at most the first +/-20 characters of your prompts or returned answers for debugging purposes, but never more).

Technical documentation

When deploying chatty-server, make sure you set the following environment variables:

Environment Variable
OPENAI_API_TYPE
OPENAI_API_HOST
OPENAI_VERSION
OPENAI_MAX_TOKENS
OPENAI_AZURE_DEPLOYMENT_ID
OPENAI_DEFAULT_MODEL
------------------------------

Running Locally

1. Clone Repo

git clone https://github.com/rijnb/chatty-server.git

2. Install Dependencies

npm install

3. Provide environment variables

Create a .env.local file in the root of the repo with the environment variables mentioned above in "Deploy".

export OPENAI_API_TYPE=azure
...

If you do not provide the OPENAI_API_KEY, the user will be prompted to provide their own key in the UI. The same applies to the Google Search keys.

4. Run App

npm run dev

5. Use It

You should be able to start chatting at http://localhost:3000/.

Configuration

When deploying the application, the following environment variables can be set:

Environment Variable	Default value	Description
OPENAI_API_KEY		The default API key used for authentication with OpenAI
OPENAI_API_HOST	https://api.openai.com	The base url, for Azure use https://<endpoint>.openai.azure.com
OPENAI_API_TYPE	openai	The API type, options are openai or azure
OPENAI_API_VERSION	2023-03-15-preview	Only applicable for Azure OpenAI
OPENAI_AZURE_DEPLOYMENT_ID		Needed when Azure OpenAI, Ref Azure OpenAI API
OPENAI_ORGANIZATION		Your OpenAI organization ID
OPENAI_DEFAULT_MODEL	gpt-3.5-turbo	The default model to use on new conversations, for Azure use gpt-35-turbo
OPENAI_DEFAULT_SYSTEM_PROMPT	see here	The default system prompt to use on new conversations
OPENAI_DEFAULT_TEMPERATURE	1	The default temperature to use on new conversations
GOOGLE_API_KEY		See Custom Search JSON API documentation
GOOGLE_CSE_ID		See Custom Search JSON API documentation

If you do not provide an OpenAI API key with OPENAI_API_KEY, users will have to provide their own key. The same applies to the Google Search keys.

Note: The value of OPENAI_AZURE_DEPLOYMENT_ID is used as-is, if it doesn't contain a dash (-). If it contains a dash, the value of the selected model is appended after the first dash, replacing the rest of the string.

For example: if OPENAI_AZURE_DEPLOYMENT_ID is dep.gpt and the selected model is gpt-3.5-turbo, the actual deployment ID used will be dep.gpt. But if the value was dep-gpt-4-32k the actual deployment ID used will be dep-gpt-35-turbo.

If you don't have an OpenAI API key, you can get one here.

Using the Google Search plugin

The application allows you to send queries to OpenAI, or to Google Search first and have the Google results interpreted by OpenAI/GPT-4. This is done by using the Google Search plugin.

How to create the keys at Google

1. Create a new project at https://console.developers.google.com/apis/dashboard.

2. Create a new API key at https://console.developers.google.com/apis/credentials.

3. Enable the Custom Search API at https://console.developers.google.com/apis/library/customsearch.googleapis.com.

4. Create a new Custom Search Engine at https://cse.google.com/cse/all.

5. Add your API key and your Custom Search Engine ID to your .env.local file (or don't and have the user fill them in, in the UI).

6. You can now select the Google Search Tool in the search tools dropdown.

Usage limits

Google gives you 100 free searches per day. You can increase this limit by creating a billing account. Please make sure you are aware of the costs before doing so.
