Hi @Mathieu Pelletier,

Make sure this filter is the last on the list of filters.
If that is already the case, please dm me so we can sort this out.
A few more information if it may help: what this filter does is add some random letters within elements that define font size as 0. If those spans are not in your HTML page, or if you have somehow css that force every element to have a font size, this may be a first hint at what the issue may be.

Best regards,
Astor

Hi thanks for the effort on this plugin. Solid idea!

It is said to work 5.0, but for some reason, this filter scrambles the text everywhere, even in standard view. This makes it so the user cannot make sense of the question at all, since nothing is intelligible. What am I missing?

All the best

Hi

Can not create an issue on "BugTracker" (https://gricad-gitlab.univ-grenoble-alpes.fr/moodle-plugins/moodle-filter_aijammer/-/issues)

Inclusion of filters from 'filter/aijammer/filter.php' using the 'filter_aijammer' class naming has been deprecated. Please rename your class to \filter_aijammer\text_filter and move it to 'filter/aijammer/classes/text_filter.php'. See MDL-82427 for more information.

@Astor Bizard
Thank you very much for the quick response and the quick fix.
It works great.
Did not want to create extra an account on the website of University of Grenoble in order to submit a bug.

PS:
I think the name "AI Jammer" is totally fine. The plugin does exactly what is expected: "jamming" AI tools by putting some random characters in the text so that AI tools can not read it.

I understand how filters work. ;)

The issue here is that the name of the plugin suggests that it blocks texts generated by AI ("AI Jammer").

But as it detects any text, I think the plugin name could be something more generic and not as specific as "AI..."

Astor,

The name of the plugin "AI ..." gives the idea that it is aimed at AI-generated text.

Hi @Ricardo Caiado,

I am sorry, but I do not understand your question.
This plugin does not interpret anything to be AI-generated or not.
All it does is alter text by adding invisible letters where it is applied.

Best regards,
Astor

Hi,

I see where the issue is coming from and am working on a fix.
I appreciate the details you brought! The bug tracker would be a more suitable place to log issues in the future, though

Best regards,
Astor

Astor,

If I copy and paste text from a Word file, for example, will the plugin interpret it as AI-generated text?

Hello,

Firstly, I want to express my appreciation for the excellent work on the AI Jammer plugin for Moodle. Overall, it has been functioning well and has been a valuable addition to our platform.
However, I have encountered an issue with the plugin specifically regarding its interaction with the "Select missing word" question type. Allow me to outline the problem:

Description:
When attempting to answer a quiz question that utilizes the "Select missing word" question type, the AI Jammer plugin interferes with the functionality.
Upon selecting either correct or false options in the dropdown menu within the question paragraph and proceeding to the next question, Moodle fails to recognize the question as answered.
Consequently, the question remains unmarked as either correct or incorrect.

Steps to Reproduce:

Navigate to a quiz containing "Select missing word" question type.
Answer a question by selecting an option from the dropdown menu.
Proceed to the next question.
Expected Behavior:
The answered question should be recognised as answered by Moodle.

Actual Behavior:
The question remains unrecognized as answered by Moodle.

Additional Information:

This issue started occurring after the installation of the AI Jammer plugin.
Deactivating the AI Jammer plugin for the quiz restores the functionality of the "Select missing word" question type.

The format required for the "Select missing word" question type is: "There is a missing 1 in this 2."
1 = word
2 = text
(Note: there should be double brackets[] around '1' and '2', but they seem to be filtered out here.

Interestingly, the plugin does not interfere with the functionality of the "Drag and drop into text" question type, which shares the same formatting requirements as the "Select missing word" question type.

Hypothesis:
It appears that the interference stems from the AI Jammer plugin, possibly due to its handling of the formatting required by the "Select missing word" question type.

Hi @Ricardo Caiado,

This plugin is a filter, which can be enabled in each activity from the Filters menu section.
It will alter the page to make copy and pasting more difficult. It should not impair normal reading of the page to users.
You can send a link to the plugin's page to teachers so they can see what it does. If you think the description provided is unclear, please feel free to DM me suggestions to a more complete description.

Best regards,
Astor

Hi,

If a teacher asked me how AI Jammer works, what should I tell him?

This is a great plugins.
It works as stated.
Very easy to install and use.
I think it would be a very good candidate for MUA to propose to add to Moodle core.
