How it Works ?

This component can be used in different modes:

with the CLI ( interactive mode, automatic mode or with the help of a template).
In your application with the API.

1. Interactive / Automatic Mode

In interactive mode, the CLI will ask you for some parameters (topic/title, language, intent, audience, etc.).

In automatic mode, you need to supply all the necessary parameters to the command line. This mode of operation allows you to create a multitude of contents in series (for example, in a shell script).

Both modes will use different predefined prompts to generate the content:

Generate the outline of the post (with the SEO description, SEO title, the slug).
Generate the introduction.
Generate the content of the different heading of the outline.
Generate the conclusion.

The final result is in Markdown and HTML.

2. Template Mode

A template contains a document structure within a series of prompts. Each prompt will be executed in a specific order and will be replaced by the answer provided by the AI. It is possible to use different formats: Markdown, HTML, JSON, etc.

The main advantage of the template usage is the customisation of the output. You can use your own prompts. Templates are also interesting if you want to produce different contents based on the same structure (product pages, landing pages, etc.).

3. Completion Parameters

One of the problems of AI content generation is the repetition of the main keywords. This script also uses temperature, frequency_penalty, and presence_penalty parameters to try to minimize this. See the OpenAI API documentation for more details.

4. Publish on Wordpress

When generating, the CLI gives you the ability to publish the content to your WordPress blog. Other CMS will be supported in the future. We need to support some headless CMS.

Warning

This is an experimental project. You are welcome to suggest improvements, like other prompts and other values for the parameters. The cost of the API calls is not included in the price of the CLI. You need to have an OpenAI API key to use this CLI. In all cases, you have to review the final output. AI can provide incorrect information.

Installation

The CLI and API are available as a NPM package.

# for the API
npm install julius-gpt -S
# for the CLI
npm install -g julius-gpt

CLI

The CLI has 4 groups of commands:

prompt : custom prompt management.
post: generate a post in interactive or auto mode.
template-post : generate a content based on a template.
wp: wordpress related commands : list, add, remove, update WP sites & publish posts.

~ julius -h

  template-post [options]  Generate a post based on a content template
  wp                       Wordpress related commands. The

Generate a Post

You need to have an OpenAI API key to use this CLI. You can specify your OpenAI API key with the -k option or with the environment variable OPENAI_API_KEY.

See the CLI help to get the list of the different options.

 ~ julius post -h

Automatic Mode

 ~ julius post -tp "5 reasons to use AI for generating content"

Use the other parameters to personalize content even further.

A more advanced command

 ~ julius post -fp 1.5 -g -l french -tp "Emprunter\ avec\ un\ revenu\ de\ retraite\ :\ quelles\ sont\ les\ options\ \?" -f ./emprunter-argent-revenu-retraite -c Belgique -d

This command will generate a post in French with a frequency penalty of 1.5 for the audience of the country : Belgium. The topic (tp arg) is written in French.

Interactive Mode

 ~ julius post -i

It is not necessary to use the other parameters. The CLI will ask you some questions about the topic, language, ...

Generate Content Based on a Template

The template file can be in the markdown or HTML format. The template extension will be used to determine the final output.

 ~ julius template-post -t <file>.[md|html]

The CLI will execute all prompts mentioned in the template file. Each prompt short-code will be replaced by the output provided by the AI.

Template structure

Here is a simple example for the template file:

{{s:Your are an prompt tester. You have to write your answers in a makrdown block code.}}
{{c:your answer has to be "Content of prompt 1."}}

# Heading 1
{{c:your answer has to be "Content of prompt 2."}}

Prompt "s" is the system prompt Prompt with "c" are content prompt. they will be replaced by the output provided by the AI.

Like in Langchain, you can provide some input variables in the template like this one :

{{s:Your are an prompt tester. You have to write your answers in a makrdown block code in language : {language}.}}
{{c:Quelle est la capitale de la France ?"}}

# Heading 1
{{c: Quelle est la capitale de la Belgique ? "}}

Now, you can execute this template with the following command :

 ~ julius template-post -t <template-file>.md -i language=french

This is an experimental feature and the template syntax will be modified in an upcoming release.

Supported Models

By default, the CLI is using the latest Open AI model. We are working on the support of the following ones :

Provider	Models	Status	.env variable API KEY
OpenAI	gpt-4, gpt-4-turbo-preview	Stable	OPENAI_API_KEY
Mistral	mistral-small-latest, mistral-medium-latest, mistral-large-latest	Experimental	MISTRAL_API_KEY
Anthropic	Claude	Next Release	NA
Groq	Mistral, Llama	Next Release	NA

All models require an API Key. You can provide it either in the .env file or with the CLI parameter '-k'

You can choose your model with the -m parameter :

 ~ julius post -m mistral-large-latest ....

Use the help to have the list of the models

 ~ julius post -h

or

 ~ julius template-post -h

Custom prompts

Why custom prompts?

Default one are too generic.
Julius's default prompts are written in English. Customs prompts can be created for a specific language.
Give the possibility to add persona, writing style, remove IA footprint, add custom editorial brief, ....

Default prompts

Julius uses a set of prompts for content generation that can be customized by creating a new version in a separate directory. Each prompt is stored in a different file.

File name	Description	Inputs
system.txt	Can be used as an editorial brief or to add important information such as personas, editorial style, objectives, ...	None
audience-intent.txt	Use to generate the audience and intent based on the article's subject.	{language} {topic}
outline.txt	Use to generate article structure.	{language} {topic} {country} {audience} {intent}
introduction.txt	Use to generate the article's introduction.	{language} {topic}
conclusion.txt	Use to generate the article's conclusion.	{language} {topic}
heading.txt	Use to generate the content of each heading.	{language} {headingTitle} {keywords}

Create a custom prompt

1. Make a copy of the default prompts

 ~ julius prompt create [name] [folder]

eg. :

 ~ julius prompt create discover ./my-prompts

This command will copy the default prompts into the folder : ./my-prompts/discover

2. Modify the prompts

Now, you can modify and/or translate the prompts in this folder

3. Use your prompts in the CLI

In the automatic mode, the cli will ask you the custom prompt path

 ~ julius -i

You can also use a CLI parameter "pf" to specify the folder path

 ~ julius -pf ./my-prompts/discover ...

}

This JSON file can be generated with the command julius post or with the API.

By default, the Wordpress REST API doesn't allow you to update the SEO title and description. This information is managed by different plugins, such as Yoast SEO. You can code a plugin for this.

A plugin example for Yoast can be found in this directory: julius-wp-plugin You can create a zip and install it from the Wordpress dashboard.

You can code something similar for other SEO plugins.

~ julius wp post www.domain.com|id categoryId post.json

The first argument is the domain name or the ID of the site.
The second argument is the ID of the category on this WordPress. You can get the list of categories with the command julius wp categories www.domain.com|id
The third argument is a boolean to indicate if the WP used Yoast SEO plugin. If true, the SEO title and description will be published.
The fourth argument is the path to the JSON file containing the post.
