Shaded rows are where the two answers disagree and both listings have answered. A row where one side has not stated a fact is left plain, because silence is not a difference.
Obsidian
Notes that stay as plain files on your own disk
Obsidian keeps a vault of Markdown files on the local disk and builds links, backlinks and a graph over them. For a creator that means the idea list, the script drafts and the research notes outlive the app: no export, no account, nothing to be locked out of. The app itself is free without a sign-up. Sync and Publish are paid add-ons rather than the product, and a commercial licence is asked for only when notes are used for work at a company.
Our note
Try it before paying for anything, since the free app is the product and the add-ons only matter once you are working across two devices. The commercial licence is the one people miss: it applies to using notes for company work, not to writing for your own channel.

ProWritingAid
Style and grammar checks for long drafts
ProWritingAid reports on a whole manuscript rather than a sentence, with checks for pacing, repeated phrasing, sticky sentences and dialogue tags that Grammarly does not attempt. The reports take a while to read and are worth it once. Free accounts are limited to 500 words at a time, which rules out the long-document work the tool is best at.
