Can anyone recommend a spellchecking LSP that also checks grammar and basic syntax, like most office tools? I'd primarily like to use it with Markdown and Typst.
I currently use codebook as spellcheck LSP, but I'm not happy because I still need to use external tools quite often to find basic spelling mistakes like missing commas.

@leona The natural language processing in Jetbrains IDE (which is now built-in, but used to rely on Language tool via Grazie) seems pretty good.

So perhaps look up if there's any LSP using Language Tools for your editor.

(Any JetBrains IDE + Texify gets you a very good LaTeX experience, but I don't know if we have a Typst plugin here)

@Sobex I used JetBrains IDEs for many years nearly exclusively, but currently for the work I'm doing (Nix, Python and Typst) primarily), a basic Terminal Editor with LSPs mostly works equivalent or better. I only use IntelliJ (Ultimate) for large-scale refactors currently. It got to annoying for me tbh for basic tasks.

I currently use Helix as my go-to-editor. Tho thank you for your answer.

@leona Searching for "Language tool LSP" brought up some blog post about NeoVIM + Language Tools, so there's probably a way of getting something to work, in various editors.

(Also annoyingly it seems Typst on JetBrains is a third party paid plugin).
