Interesting modern AI-ish feature was introduced in the latest 5.2:

Starting from JEB 5.2, you may use the experimental “JEB Assistant” to infer names for decompiled methods and method parameters.

https://www.pnfsoftware.com/blog/jeb-assistant/

Nice feature, currently several limitations apply:

• The assistant is limited to decompiled native routines. It will not work for dex/dalvik decompilations.
• The assistant will refuse to work on overly long routines (whose decompilation exceeds several thousand characters).
• The assistant is not available via the JEB API and requests are rate-limited (at most one every 5 seconds).

does it mean that feature is online only...
like JEB talks to backend servers and got the AI-ish result over API?

Yes this feature needs to be online. It asks you to accept to send the decompiled result to JEB servers.

It means that (most probably, just an educated guess) it also conveys the request for this feature with the corresponding license?
....

OK; I did not sniff the outgoing packages or reverse engineer JEB to understand what it conveys when using assistant. I have only checked if it is working or not!

Since it only "guesses" a better function name, it is useless for me right at the moment. Bu I believe, they will improve this feature!

After trying, JEB's decompilation effect is really good: it can automatically obfuscate the original decrypted string after confusing the garbled string

Interestingly; JEB can decrypt APKEncryptor by default. I was impressed!

Check the github time stamps: it is from March 2021. With source code available. It is not too difficult to decrypt it manually either. A lot easier than with ConfuserEx for Windows based .Net at any rate.

I did.

I know; I have shared the repo above.

It might not be difficult but time consuming!

I don't get this one. Can you protect an APK with ConfuserEX?
