Reddit does not run a sitewide AI classifier, but the community and the moderators run one in their heads. r/AskReddit, r/relationship_advice, r/IAmA and any academic sub are especially strict. TextSight rewrites the Reddit tells (Here is the thing, Hot take, bullet lists on a discussion thread, the hope this helps closer) so your post reads like someone who actually uses the sub. It will not write community knowledge for you and it will not turn rule-breaking content into safe content.
Reddit does not ship a sitewide AI classifier, and the platform has been deliberately quiet about whether one is in development. The penalty is community-driven, which makes it faster and more public than algorithmic suppression on most other platforms.
Reddit skews technical and pattern-aware, and sitewide volume of ChatGPT content drove the learning curve hard through 2024 and 2025. By 2026 the median active Redditor can flag a ChatGPT post inside two sentences. The signal is usually the opener (Here is the thing, Hot take), a bulleted reply on a discussion-thread question that called for a paragraph, or the absence of any first-person specifics.
r/AskHistorians, r/changemyview, r/AcademicPsychology and r/legaladvice ban AI content outright and remove flagged posts on sight. Most academic and writing subs follow the same rule. r/AskReddit, r/relationship_advice and r/IAmA are particularly strict on inauthentic top-level posts. Many casual subs do not ban AI in the rules but the community downvotes it anyway. Always read the sidebar before posting; modlogs are public on reveddit so deleting a removed post does not hide the removal.
A flagged post collects negative karma on the post itself and negative karma on any replies you make defending it. Accounts that drop below certain karma thresholds get rate-limited sitewide and auto-filtered by some subs. The damage is not limited to one bad post; it compounds across the account and follows you into unrelated communities. A LinkedIn post that reads AI quietly underperforms; a Reddit post that reads AI gets called out loud and the rest of the thread reads through that lens.
The AI rewriter changes how your prose reads. It does not change whether your post belongs in the sub, whether it follows the rules, or whether it adds value. Get those right first.
Every active sub publishes its rules and most call out AI content explicitly. If the sidebar bans AI-assisted posts, no amount of rewriting makes a draft safe; write it from scratch instead or pick a different sub. If the rules require a flair, a tag, a specific format, or a body length minimum, those still apply.
One thoughtful contribution you have a real stake in is fine to rewrite. Industrialised posting of AI-assisted content across multiple subs to push a product, a link, or a narrative is astroturfing regardless of how human the prose reads. Reddit and most subs have rules against this and accounts that get flagged for it lose karma and access fast.
Every active sub has a distinct cadence. r/programming tolerates technical precision and bullet-light structure. r/relationships demands conversational paragraphs with anecdote. r/explainlikeimfive wants short sentences and one analogy. r/AskReddit punishes any structure at all. Read the top three replies on a similar question in the same sub before drafting so your version matches their register; then run TextSight to strip the model default the community would otherwise spot.
These five tells account for the bulk of is-this-ChatGPT replies. They cut across subreddits but the dosage varies: r/programming users tolerate slightly more structure, r/relationships users punish any structure at all, and r/explainlikeimfive sits somewhere between.
Plus its variants: So basically, The truth is, I will be honest with you, Let me explain. ChatGPT cycles through roughly six Reddit-flavored opener templates and the community has memed them all to death. Here is the thing is the single most-flagged opener on Reddit by a wide margin. Fix: open mid-thought, the way a real Redditor types when they are already invested. Skip preamble entirely. Start on the verb or the detail, not the framing.
Plus Unpopular opinion, Real talk, and Friendly reminder headers. Real Redditors almost never label their own takes as hot. The label itself is a tell, partly because ChatGPT defaults to it on any opinion prompt and partly because actual hot takes do not need flagging; the downvotes do that. Fix: just state the opinion. No framing label. If it is genuinely contrarian the comments will tell you.
A discussion-thread reply on Reddit is supposed to be a paragraph or two of conversational prose. ChatGPT defaults to a bulleted response with parallel structure even when the question is what is your experience with X. Bullets on a personal-experience question read as off-tone instantly, even if the content is fine. Fix: collapse all bullets back to prose unless the post is genuinely a how-to or a comparison. On r/AskReddit, r/relationships and most advice subs the rule is zero bullets.
This. So much this. Take my upvote. Underrated comment. The fake Edit: thanks for the gold, kind stranger. These phrases were once organic and are now performative shorthand the model has absorbed. Using them deliberately as garnish on an otherwise model-shaped post is a stronger tell than the original tells because it reads as a model trying to pass. Fix: cut all of them. If you want warmth in the post, add a specific personal aside instead of a community catchphrase.
The strongest Reddit tell is the absence of one specific anchor: a year, a number, a place, a tool, a coworker, a specific subreddit you actually frequent. Real Reddit answers ground a claim in personal detail; ChatGPT drafts float above the topic at generic altitude. Pattern-aware Redditors stop scanning for the other tells the moment they hit a concrete anchor, and vice versa. Fix: add one true anchor per 250 words. If you cannot, the post probably does not have the substance the sub rewards and the AI rewriter will not save it.
Reddit detects aggressive paraphrasing. Pick the lightest mode that clears the tells.
Balanced preserves the conversational register Reddit rewards while removing the structural tells. It rewrites openers, collapses bullet structure, and trims hedged closers without paraphrasing claims into something different. Use Balanced for any post 200 to 1,500 words on a typical advice or discussion sub.
A 50-word comment usually only contains one or two tells, most often the Here is the thing opener or the hope this helps closer. Light does a targeted phrase rewrite and leaves the rest alone. Faster and safer for short content where Balanced would over-edit.
Maximum aggressively restructures sentences and paraphrases claims. On factual or technical subs (r/programming, r/AskScience, r/explainlikeimfive top answers, r/legaladvice, r/personalfinance for anything numeric) Maximum can change a percentage, a year, or a code claim into something wrong. On any sub, the pattern of heavy structural rewrites is itself something pattern-aware readers learn to spot in 2026. Use Maximum only on low-stakes casual subs and verify after.
Reddit posts range from 50-word comments to 2,000-word essays. The five-step workflow takes about 60 seconds on a typical 200 to 500 word reply once the pattern is muscle memory.
Before rewriting anything, confirm the sub allows AI-assisted content. r/AskHistorians, r/changemyview, r/AcademicPsychology and r/legaladvice ban it outright and removal is automatic on report. Most academic and writing subs follow the same rule. If the sub bans AI content, no amount of rewriting makes the post safe; write it from scratch instead or pick a different sub.
Delete Here is the thing, Hot take, So basically, and any hope this helps sign-off. Open on the verb or the detail. Close on the last concrete point. This single edit usually moves Authenticity Score by 20 to 30 points on a typical Reddit reply and takes less time than running the AI rewriter itself.
Spend 10 seconds reading the top three replies on a similar post in the same sub before you rewrite. r/programming tolerates technical precision. r/relationships demands conversational anecdote. r/explainlikeimfive wants short sentences. Your version should match their cadence and register, not the model default.
Convert any bullet block back to prose unless the post is a true how-to. Add one specific personal anchor: a year, a number, a place, a tool, a coworker. The anchor does more credibility work than any phrase rewrite. If you cannot add one, the draft probably is not ready to post.
Paste into the AI rewriter on Balanced for a typical post, Light for a short comment. Target Authenticity Score above 75. Sentence-level flags show exactly which lines still read AI. Verify any numbers or named subreddits survived the rewrite intact; Balanced is much safer than Maximum here but occasionally still nudges a value. Drop the post in a low-stakes sub first if you are unsure.
A ChatGPT-generated reply to an r/personalfinance question about whether to pay off a 6 percent car loan or invest the cash. The original has every Reddit tell. The rewrite uses the five-step workflow.
"Here is the thing about a 6 percent car loan versus investing. Hot take: most people get this wrong. A few points to consider:
• 6 percent is a guaranteed return when you pay it off
• The market historically returns 7 to 10 percent, but it is not guaranteed
• Emotional peace of mind has real value too
So basically, the math leans slightly toward investing, but the psychology leans toward paying off the debt. The truth is there is no universal answer. Hope this helps, and best of luck with your decision!"
"6 percent is a guaranteed return. The S&P 500 long-run average is around 10 percent but that is an average over decades, not a promise for the next 5 years. I had a 5.9 percent car loan in 2023 and paid it off early. Was the math marginally better to invest? Probably. But I also stopped checking my account balance every Friday wondering if a market dip was costing me the difference, which turned out to be worth more to me than the 1 to 4 percent spread. The honest answer for you: if the loan stresses you out, pay it. If it does not, the math says invest. Both are defensible."
What changed: killed the Here is the thing opener, the Hot take framing, and the hope this helps closer. Collapsed the three-bullet middle to prose. Added a personal anchor (the 5.9 percent loan in 2023) which is the kind of detail r/personalfinance actually rewards. Replaced em-dashes with periods and commas. Score moved 77 points. The new version reads like someone who has been in the situation, not a model summarising it.
