If you are using VScode, get familiar with cline. Aider is also excellent if you don’t want to modify your IDE.
Additionally, Jetbrains IDEs now also have built-in local LLMs and their auto-complete is actually fast and decent. They also have added a new chat sidepanel in recent update.
The goal is NOT to change your workflow or dev env, but to integrate these tools into your existing flow, despite what the narrative says.
