Reddit post tester
Will your Reddit post work?
Paste the draft and pick the subreddit. You get a score against what that community normally upvotes, what is helping, what is hurting, and the rules it might break. Three free tests, no signup.
How it looks in the feed
How the score works
- 01
A model reads your draft and answers 42 yes or no questions about it. Is the title a question? Does the post promote something? Does it read like AI wrote it?
- 02
Each answer is weighed against 8,297 real posts from 108 subreddits. A post counted as a win when it scored in the top quarter of its own subreddit, so a small community and a huge one are judged on the same terms.
- 03
The score is where your draft lands among real posts the model never saw. Given two of those from the same subreddit, it picked the better one 71% of the time. A coin gets 50%.
It runs on Cloudflare's Clef model and our own subreddit data.
Common questions
How accurate is the Reddit post tester?
Given two real posts from the same subreddit, one that did well and one that did not, it picks the right one about 7 times in 10. A coin gets 5. It reads the words and nothing else, so it cannot see your account, the hour you post, or what else is on the front page that day.
Can it tell me if my post will be removed?
Not reliably, and we tested it. Removed posts lose their text, so there is very little to learn from. What the tool does instead is check your draft against the subreddit's written rules and show how often new posts there get removed. Karma and account age limits are listed too, but only you know your account.
What does the score mean?
It is a rank, not a promise. 70 means your draft scores higher than 70% of the real posts we tested the model on. High-scoring posts landed near the top of their subreddit far more often, but plenty of average-looking posts take off and plenty of good ones die.
Why does asking for help score low?
Because that is what the data says. Posts asking for help with a personal problem get answers, which is the point of them, but they rarely get upvotes. If answers are what you want, ignore that part of the score.
Do you keep my draft?
No. It is sent to the model, scored and dropped. We do not store or log it. The only thing we keep is a count of how many tests you have run.
Which subreddits does it cover?
The ones we have guides for. Each guide holds the rules, karma requirements and removal rates the tester draws on, and you can read it before you post.
Why only three tests?
Each test costs us money to run. Three is enough to draft, fix and check. If you want more than a score, that is what the application is for.
