Free Reddit post checker: test before you post
A free AI moderator simulation that checks your draft against published subreddit rules and six Reddit-native removal risks before you post.
This is a conservative simulation, not a real moderator decision. It cannot inspect private AutoModerator configuration, hidden account thresholds, or moderator discretion.
How it works
Choose a subreddit, enter your draft, then run the check and use the feedback to edit before publishing.
Step 2
Draft in Reddit context
Write or paste the title and body inside a Reddit-native post preview. Your draft stays in the editor if the lookup or simulation fails.
Step 3
Review the simulated verdict
Run the check to compare your draft with published rules. Review the verdict, concrete edits, and any suggested rewrite. Expand the findings to see each rule and the sources used.
What is a Reddit post checker?
A Reddit post checker reviews a draft before publishing. This one simulates a conservative moderation pass: it compares the title and body with the target community's published rules, then checks visible Reddit-native risks that commonly lead to removal or poor fit.
What it can inspect
- Published subreddit rules and descriptions
- The title and body you enter in the editor
- Promotion, link, effort, disclosure, fit, and tone risks
What it cannot inspect
- Private AutoModerator configuration or hidden filters
- Account-age, karma, or participation gates not published
- A real moderator's final judgment or changing context
Common reasons Reddit posts get removed
Published community rules come first. The simulation also checks six recurring risks so a short rules page does not become false confidence.
- The post does not fit the subreddit's topic or expected format.
- A product, company, or personal project reads as promotion.
- An external link is unnecessary, gated, or too prominent.
- The post is too short, generic, repetitive, or context-free.
- Relevant affiliation or incentive is not disclosed.
- The writing sounds templated, manipulative, or unlike a human.
Methodology and sources
Rankhog compares your draft with the community's published rules. Successful reads may be cached for seven days. Your result includes the source links and capture date so you can check the rules yourself. If the rules cannot be read, the simulation does not run.
Reddit also describes its own Post Check as experimental and fallible. Read the Reddit Post Check guide.

Example input and output
The live tool runs with your own context. This example shows the kind of practical answer you can expect.
Sample input
- Post title
- What we learned after 31 SaaS demos from Reddit leads
- Subreddit
- r/SaaS
Needs edits
The post can work if it leads with the useful lesson instead of the product.
- Add more context before the link
- Make the lesson useful without your company name
- Disclose affiliation if the product is mentioned
Use it with subreddit-specific context
Pair the tool with Rankhog's subreddit guides when you are posting somewhere strict. The guides cover rules, stats, what works, and removal risks.
Questions about Reddit post checker
How does the Reddit post checker work?
Choose a subreddit and enter your title and body in the Reddit preview. Run the check to compare your draft with the published rules. Rankhog checks every published rule once, plus subreddit fit, self-promotion, external links, low effort, disclosure, and human tone.
Can it tell me whether my Reddit post will be removed?
No. It evaluates public rules and visible draft risks, but it cannot see private AutoModerator filters, hidden karma or account-age requirements, or a moderator's judgment. The verdict is guidance, not an acceptance guarantee.
Where do the subreddit rules come from?
Rankhog reads published community details and rules, caches successful reads for seven days, and links the Reddit sources with their capture date in your result. If rules cannot be read, the simulation does not run.
What if a subreddit has no published rules?
If a community publishes no rules, the result clearly says that it used general Reddit-native checks only. It never invents community rules.
What changes when I subscribe to Rankhog?
Rankhog subscribers get unlimited daily checks with burst protection, plus a workflow for finding relevant Reddit threads and drafting replies with community context.
