[~amitp7007] thanks that worked for me as well.
Putting in additional bits for someone who might need a complete solution,
1. Create a file called custom-mimetypes.xml, with following content, notice the <mime-info> tags added to the xml provided by Amit.

2. Just put in your classpath, that's it, Tika will pick it up to add a new matcher.
*Couple of callouts*,
# This is still not an accurate signature of AI files, we are just enabling this to match files with the mentioned signature as AI as well.
# You still need to hint Tika, with a filename, {{{color:#9876aa}tika{color}.detect(inputStream, fileName) }}then only it will resolved as ai, otherwise it will be matched to both pdf and ai, though resolved as pdf.
# You might find [this|https://tika.apache.org/1.8/parser_guide.html#Add_your_MIME-Type] guide helpful as well.
Since, its been quite sometime since the last comment on this thread, has there been any progress to match AI files better?

> Project: Tika
> Issue Type: Bug
> Components: core
> Affects Versions: 1.16, 1.17, 1.18
> Reporter: Amit Pandey
> Priority: Major
> Attachments: example.ai

>
> There is in-consistency in detecting **ai* types files when using different overloaded detect method. When I am using _detect(String filename)_, it gives correct file type - "*application/illustrator*". If I use _detect(InputStream is, String filename)_ or _detect(File fileObj)_ - it gives file type "*application/pdf*".
> Here is sample code I used.
