Most Reddit removals are silent: your post looks fine to you, but nobody else sees it. WillItStay is a pre-publish checker. Paste your draft, pick a subreddit, and it predicts whether it survives or gets removed by AutoMod, the spam filter, karma and age gates, or a shadowban. It names the exact rule you would trip, then rewrites the post to pass. What's different: it predicts survival per subreddit before you post, not after. Free shadowban checker, no login.
