About this extension
RedReplier reads a subreddit's own rules before you post there, then checks your draft against those exact rules. Both happen on the page you are already on.
Reddit marketing fails in a specific way. You write something useful, post it, and a moderator removes it an hour later for a rule you never opened. Or the post survives and quietly earns nothing because the subreddit wanted a disclosure you did not give. RedReplier moves that discovery to before you hit submit.
WHAT THE PANEL SHOWS
Open any subreddit and a small pill appears in the corner. Click it and you get that community's self-promotion stance, read live from Reddit's own rules, plus the member count and every published rule in full.
The stance is not a guess at a category. It quotes the sentence the moderators wrote. If a subreddit allows one mention per 60 days and requires you to disclose affiliation, that is what you see, in their words.
Karma minimums and account-age gates get pulled out separately, because those are the two reasons a post disappears before anyone reads it.
CHECKING A DRAFT
Paste a reply or a post into the extension and it scores the draft against the rules of the subreddit you are currently viewing.
You get a risk level, a score out of 100, the exact phrases that read as promotional, an explanation for each one, and a rewrite you can copy. Where a rule is broken, it says which rule.
A generic spam checker cannot do this. Two links is fine in a community that allows links and a removal in one that does not. The check knows which one you are in.
WATCHING FOR THREADS WORTH ANSWERING
Add the terms your product actually solves. Post titles containing them get underlined as you scroll, with the matched term shown next to the title.
No feed to monitor and no alerts to configure. The threads you would have scrolled past mark themselves while you browse normally.
WHO USES IT
Founders posting about what they built. Marketers running community accounts. Anyone who has had a post removed and only then read the rule that killed it.
The full workflow, saved subreddit research and reply drafting lives at redreplier.com. This extension is the part that runs where the posting happens.
WHAT IT SENDS
Subreddit rules are read from Reddit's public API using your own session, exactly as the page does. Drafts you choose to check are sent to the RedReplier API and nowhere else. Your keywords stay in local browser storage on your device.
No page is read unless you are on Reddit, and nothing is sent anywhere until you press Check draft.
