Inspections
Inspections check your LaTeX and BibTeX as you write, and highlight any possible issues. If you see a minor bug in an inspection, like some missing metadata about commands or environments, you are encouraged to check if you can fix it yourself.
Suppress inspections
Most inspections can be ignored for only a single line, environment or file. To do this, use the format %! Suppress = MyInspectionName. The easiest way is usually to use the available context menu on the inspection warning itself.
Custom inspections
If you have project-specific issues which need to be highlighted, but are of no use for the general public, you can create your own search and replace inspections. See Create custom inspections | IntelliJ IDEA Documentation.
Spellchecking
IntelliJ has a default spellchecking inspection, see Spellchecking | IntelliJ IDEA Documentation.
Grammar checking

For more information about Grazie, see https://plugins.jetbrains.com/plugin/12175-grazie/ and Grammar | IntelliJ IDEA Documentation.
If you want more advanced features than Grazie provides (e.g. provide your own rules in addition to the included ones), have a look at the machine-learning based https://plugins.jetbrains.com/plugin/16136-grazie-professional. While Grazie comes bundled with IntelliJ, Grazie Professional must be installed explicitely.
