No login, no account connection. Just a public Reddit username. Tools like MediaFast use the same real Reddit data to help you find subreddits and post at the right time, so the roast can double as a quick gut check before you start posting seriously.
Type any public Reddit username, no u/ prefix needed. It works for your own account or anyone else's public profile.
The tool reads account age, karma, subreddit activity, and a sample of recent posts and comments straight from Reddit's own API.
A fixed formula computes an A+ to F grade from the real stats, and an AI writes a roast grounded in that same data, plus one genuine compliment and a few concrete tips.
The grade is a fixed formula, not an AI guess. It weighs account age, total karma, subreddit diversity, and recent activity, in that order of impact.
| Grade | Label | Score Range | What It Usually Means |
|---|---|---|---|
| A+ | Reddit Power User | 90-100 | Years-old account, high karma, active across many communities. |
| A | Established Redditor | 80-89 | Solid age and karma with a decent spread of subreddits. |
| B | Solid Contributor | 65-79 | Reasonable account age and karma, moderate activity. |
| C | Average Lurker | 50-64 | A typical account. Some karma and history, nothing standout yet. |
| D | Barely There | 30-49 | Young account, low karma, or very narrow subreddit activity. |
| F | Ghost Account | 0-29 | Brand new, near-zero karma, or almost no visible activity. |
These are illustrative examples of the tone, not real generated roasts. Every real roast is written fresh from the actual account's data.
"Ten years on this site and your top post is a screenshot of a parking spot."
"You have more karma from one lucky meme than from a decade of comments."
"Posting in fourteen different subreddits but somehow an expert in none of them."
"Your account is old enough to vote but your karma still looks like a rounding error."
"You comment more than you post, which honestly explains a lot."
"That much karma from three subreddits is either dedication or a serious rut."
This tool is built for fun, not harassment. Only run it on public accounts, do not use the output to target or bully anyone, and remember the AI only knows what Reddit's public API exposes, not the full context behind any post or comment.
The grade reflects public, surface-level stats, not the quality or value of your contributions. A quiet, focused account in one niche subreddit can still be a genuinely valuable community member with a modest grade.
Account age can't be sped up, but karma, subreddit diversity, and recent activity all respond to genuine participation. Comment before you post, spread activity across a few relevant communities instead of just one, and keep showing up. If you also want help finding the right subreddits for a product or brand, MediaFast can suggest communities sized to where an account already stands.

Everything you need to know about how the roast and the grade work.
Enter any public Reddit username and the tool pulls that account's real karma, account age, subreddit activity, and a sample of recent posts and comments through Reddit's own API. An AI then writes a roast grounded in those real numbers, and a separate, code-computed grade (A+ to F) is calculated from the same stats, not by the AI.
No. The A+ to F grade is calculated by a fixed formula based on account age, total karma, subreddit diversity, and recent activity. Only the roast commentary itself is AI-generated. This keeps the grade honest and reproducible instead of depending on how creative the model feels that day.
Yes. Enter your own username just like anyone else's. Since the tool only reads public Reddit data, it works the same way whether you are checking your own account or someone else's.
The grade weighs four things: account age, total karma, how many distinct subreddits you post or comment in, and recent activity volume. A newer account, a narrow posting pattern in just one or two subreddits, or a quiet recent history can all pull the score down even if your karma total looks decent.
Yes. The AI is only given your actual karma numbers, account age, subreddit list, and a sample of your real recent posts and comments. It is instructed to roast based only on that real data, not to invent posts, numbers, or events that never happened.
Yes, the Reddit Account Roast is completely free with no login required. It is rate-limited to prevent abuse, so heavy repeated use in a short window may briefly ask you to wait a minute.
Enter any Reddit username and get roasted by AI based on real karma, account age, and posting history. Free, instant, brutally honest.
