Harnessing the Power of AI Assistant in IntelliJ IDEA

AI Assistant provides AI-powered features for software development based on the JetBrains AI service. The service transparently connects you, the IDE user, to different large language models.
In this session, Anton will demonstrate the capabilities of AI Assistant in IntelliJ IDEA. You will learn how the tool helps you explore and improve existing code as well as write new code in different scenarios.

This sold me on the Ai Assistant. One of the last questions about the JDK migration from Java 8 to 17 is exactly what I need this for. Thank you.

[@araghuraman1]

It was exhausting. It seemed like Anton was really wary of the code generation. I may need to experiment more, and in this sense Anton succeeded in provoking my curiosity.

[@marmont8005]

After 3 days of use my monthly limit is reached. What am I paying for?

[@sna241]

Code reviews be like:
Senior engineer: "Try doing it this way"
Junior engineer: "But Chat GPT said this is better!"

[@VladislavDerbenev]

Sounds like "seniors" gotta have to come up with actual reasons this time

[@sna241]

@@VladislavDerbenev No one should trust both blindly.

[@wernerjacobs3282]

Nice presentation, looking forward to use it

[@drakenra]

Do you store our code that we send to the server?

[@krellin]

you should assume everyone does, although everyone will tell you otherwise...
same way as microsoft will say you private repos in github are private. In reality all that data you stream is too valuable to further train the models. Especially cos you alter and correct the response of the ai so thats literally a labeled data for free.

[@princessazula8897]

They store the code but don't share them lol

[@miloserus]

I don’t like that it ignores the existing doucumentation when writing documentation for a function. Sometimes it just adds parameters and removes the description of the function

[@limonanaful]

Can the assitant perform on many files? For example remove all try catch in files in specific directory

[@AntonArhipov]

I think the structural search and replace feature (SSR) works fine for this task. But maybe in the future the AI assistant could provide guidance for tasks like this

[@kyleMcBurnett]

It only works on one file at a time. Or one chat at a time. You can't ask it to do a refactor across the whole project

[@slimyelow]

There is way too much junk that comes with this. It just isn't ready for the level it proposes to be. It is still more productive to use GPT even if it means copying and pasting code and asking many questions etc. But I found that when interacting with GPT you form a productive conversation with a coding partner. You are still required to think. You must ask the right questions and help yourself. GPT is like a work colleague that never gets annoyed when you ask all the time, which is so great. Getting some magic coding AI that will do all the work for you from one prompt alone is a far cry from reality just now.

[@aj-jc4cv]

Does the AI Assistant use chatgpt 3.5 or 4 behind the scenes?

[@AntonArhipov]

Both, depending on a feature.

[@aj-jc4cv]

@@AntonArhipovthanks, great presentation. AI additions are a game changer.

[@krellin]

@@AntonArhipov so all of this is literally delegated to gpt? i thought you built your own models
also if it goes to chatgpt how can you gurantee its not being stored? just because openai says so...

[@AntonArhipov]

@@krellin correct, that's what OpenAI guarantees. The benefit of using GPT model now is that we can offer something now, quickly, and switch to a different LLM later, either to a different provider or self-hosted tuned model.

[@limonanaful]

You state the assitant already know the code structure. In our codebase we have conventions of controler calling manager calling mongoRepository
Can it "copy" implementation of an existing endpoint? Aka all the classes and tests related.

[@AntonArhipov]

AI assistant doesn't know the code by itself. The IDE knows. Whenever we invoke an action on some code element, the plugin triggers the analysis to figure out the dependencies.

[@javaRelated]

will we stop using Github co-pilot?

[@sayantanpodder2478]

@AntonArhipov is this ai assistant plugin available for IntelliJ Idea Community Edition (i mean is this free)?

[@AntonArhipov]

No, it is not free.

[@AjayKumar-fd9mv]

Great

[@slimyelow]

And I can't begin to praise GPT for fixing bugs, that in the past have wasted days of my life and caused me to pull my hair out. I mean it is magic, to just paste broken code and the friendly dude tells you: change it and make like this. - bam! It works ... moving on.... And that for 5 a modest bucks per month!

[@guai9632]

the popup menu this plugin shows is really annoying

[@snapman218]

Her eyes are terrifying.
