code completion in Rider is too aggressive/irrelevant/not helpful
(someone please move this post to the correct Topic/category - I don't see Rider in the list)
When I'm typing code, the code suggestions that appear in grey text have a few problems that I have listed below. I have tried to disable them, but without success. How to disable them?
- they appear too quickly
- they are not helpful 99% of the time,
- they are very distracting and slow down my work

I tried messing with the Settings under Editor → General → Code Completion, but it just made things worse. I do like the small suggestions that existed in prior versions of Rider, but now this AI thing has been taken too far, too fast! I just want my IDE to behave like it did before. Is there a setting for that? This is really slowing my productivity.
In the Settings | Editor | General | Inline Completion, you can adjust both Full Line Code Completion (local model) and Cloud Code Completion settings.
If you still cannot identify where the irrelevant inline suggestion is from, try to disable them all and check whether you have any AI plugins installed.
Hi Tao Sun,
I know that dsable or uninstall any AI plugins that could be causing the problem. Which specific IDE or editor are these settings usually found in?

I posted the configuration entry of JetBrains AI Assistant as mentioned above. If you are using other AI plugins on IntelliJ platform, you could refer to their documentation for more details.
If you cannot confirm which AI plugin is causing the problem, disable all downloaded plugins in Settings | Plugins then add back one by one, until you repro the issue of the dedicated plugin.
Tao Sun Could you please provide instructions on how to disable the AI plugins? I wasn't able to find them.
Phil Hadley See my instructions above. If you need to configure the plugin availabilty on different levels, please refer to these support articles.
SUPPORT-A-36 How to disable AI Assistant
Tao Sun - thanks, this was helpful! I didn't have the “AI assistant” installed, but I was able to use those instructions to disable the Copilot plugin, and now the IDE is working beautifully again. It's too bad your Copilot integration is so terrible, I may have to return to using Visual Studio 2026 for Windows. I use Copilot in a browser and it's very helpful, but in Rider it's always trying to suggest code when I don't want it to. Anyway, thanks for your help.
Phil Hadley For the GitHub Copilot related problems, since the plugin is maintained by Microsoft, you could try to contact the dev team on the Marketplace homepage: https://plugins.jetbrains.com/plugin/17718-github-copilot--your-ai-pair-programmer

Do you use any security software with somewhat stringent guidelines? The Defender was the cause of the comparable problem discovered in the Windows platform. https://intellij-support.jetbrains.com/hc/en-us/articles/360005028939-Slow-startup-on-Windows-splash-screen-appears-in-more-than-20-seconds https://soundbuttonspro.com/
I’ve run into the same issue in Rider, and it usually comes from “inline completion” / AI-assisted suggestions rather than the normal code completion popup. You can disable it in Settings → Editor → General → Inline Completion (or sometimes under AI Assistant depending on version). Turning that off should stop the grey ghost text from appearing while you type. Also check if “full line code completion” is enabled and disable that as well.
