I have two questions about spelling and grammar checking in InDesign (and InCopy, where applicable).
1) ID has a native spell checker, but no native grammar checker. (Why!?) Are there any good, robust (and affordable) grammar checking plugins out there? I’ve already encountered MindSteam (MindSpell, MindGrammar), but it’s ridiculously expensive ($20/month for the grammar checker and $15/month for the spell checker, but $25/month for the whole suite; that’s $300/year!!). While there ought to be a native grammar checker (a big reason why I don’t want to switch from Word to InCopy), I might consider paying $20/YEAR for a plugin.
2) How well does the native spell checker work? What would be the motivation for getting a third-party spell checker? Picking on MindSteam as an example, why should I pay $5/month more for something which is already included in the program? When I tried to find a comparison online, I only found a long-outdated comparison between MindSpell and Proximity/HunSpell for a few (relatively obscure) non-English languages.
Thanks for any help, support, and guidance you can offer!
