hunspell VS vim-litecorrect

Are you familiar with Hunspell? Dictionaries are comprehensive enough to be part of different Office Suites, so I don't see them as constricted to autocorrect.

You mentioned kinda like a con the online requirement, if you're interested in an offline method, try Hunspell. Otherwise, I just come up with this, is based on Google Suggestions API (even tho is not public):

i prefer and use hunspell

One can implement Huntspell which is what all browsers use (for example when typing in text areas). Is very simple and is C++.

Hunspell-based spell check

Excellent questions. https://github.com/wooorm/dictionaries here are some. The original dataset is here https://github.com/hunspell/hunspell#dictionaries

Since you are using already GPLv3: Why not reusing hunspell dictionaries/wordbooks? https://github.com/hunspell/hunspell

Those questions are open ones—and even the way they can be answered is unclear. Intuitively, Hunspell's suggestions are quite decent—otherwise, it wouldn't be the most widespread spellchecker, after all. A fair amount of "unhappy customers" can be easily found, too, in hunspell's repo issues. At the same time, one should distinguish between different reasons for the sub-par suggestion quality. It might be due to the algorithm itself, or due to the source data quality: the literal absence of the desired suggestion in the dictionary, or lack of aff-file settings that could've guided Hunspell to finding it.

For sure! But I don't know if that's where I want the project to go. The main idea was to do a Lua rewritte of vim-litecorrect, but then I wanted it to be able to have a better dictionary administration/availability.
