AMA stands for Ask me anything. AMA stands for Ask Me Anything. It's a question-and-answer post, made famous by Reddit, where a person introduces themselves, often with proof of who they are, and then answers whatever questions people leave in the comments.

## What AMA means

AMA is short for Ask Me Anything. On [Reddit](/platform/reddit), it names a kind of post: someone shares a little about who they are, sometimes with a photo to prove it, and invites everyone to ask them questions in the comments. They then spend a set stretch of time answering. Reddit's help center calls AMAs a long-held Reddit tradition and lists the abbreviation among the site's top expressions for newcomers.

The host can be anyone. Reddit's own examples run from actors, athletes and scientists to a lobster diver who survived being inside a whale and a 100-year-old World War II veteran. The help pages say AMAs can be serious, silly or both, and that they're for anyone with a story to tell. What makes it an AMA isn't fame. It's the promise to answer, in your own words, whatever the crowd wants to know.

Outside Reddit, AMA has loosened into a general invitation. A creator posting "AMA" on a story or in a caption is saying the floor is open for questions. In a group chat it can be half a joke: you just got back from a strange trip, so you announce an AMA. The core meaning stays the same everywhere. You're offering to answer, and the other people get to pick the questions.

One caution before you assume. On a hospital form or in a news story about doctors, AMA is a different abbreviation. Merriam-Webster lists it as short for American Medical Association and for against medical advice, as in a patient who leaves the hospital AMA. If the context is medical, it almost certainly isn't an invitation to ask questions.

## Where AMA comes from

The format is older than Reddit. [Know Your Meme](https://knowyourmeme.com/memes/ask-me-anything) traces it to an America Online chatroom called Ask Me Anything in the 1990s, and says that by December 2000 message boards had their own AMA threads where specialists took questions about their field. A LiveJournal community built around the format followed in February 2002.

Reddit is where the abbreviation became famous. Know Your Meme dates the r/IAmA subreddit to May 27, 2009, says it had nearly 800 subscribers within three days, and counts more than 2.5 million by January 2013. The name reads as "I am a", which is how many posts there open: I am a nurse, I am a pilot, I am a person who did something unusual. The same page notes that YouTube vloggers and Tumblr users adopted the idea too, collecting questions in comments or through Tumblr's ask feature, with Know Your Meme's Tumblr examples starting in January 2010.

Reddit's help center points to a few AMAs that people still talk about. It says Keanu Reeves' AMA holds the record for most upvotes, that Stephen Hawking answered questions in r/science, and that the Wall Street Journal's wine columnist hosted one in r/wine. Those examples show the range: one AMA is a celebrity event, the next is a niche expert talking to the small crowd that cares most about their subject.

## How an AMA works on Reddit today

Reddit now treats AMAs as a post type with its own tools, not just a title format. According to its help center, the person who makes the post, called [OP](/glossary/op), can schedule an AMA up to 21 days ahead and bring up to five co-hosts, whose answers are highlighted next to OP's own.

Readers get tools too. On an upcoming AMA, a Remind Me button sends you a push notification 24 hours before the start and another at the exact start time, and the reminders also land in your Inbox. Once the AMA is live, an Answered tab filters the thread to questions OP or a co-host has replied to, and an Unanswered tab shows what's still waiting, which is a good place to check before you ask something that's already been asked.

AMAs aren't limited to one place. Reddit says not every [subreddit](/glossary/subreddit) hosts them, but some, such as r/IAmA and r/AskScience, host a lot. Each community sets its own rules for who can host and what proof they need, so the same AMA might be welcome in one community and removed in another.

## How to host an AMA

Reddit's help center gives hosts a short list of expectations, and its moderator guide adds what the community's mods will usually do on their side. Put together, a well-run AMA looks like this.

1. **Contact the mods first**: Message the mod team of the community you want to post in. If they allow AMAs, they'll explain their rules, and many communities require mod approval and verification before you post.
2. **Verify who you are**: A photo of yourself is optional on Reddit, but communities often ask for proof. Reddit tells mods to keep a guest's verification documents private to the mod team.
3. **Pick and announce a time**: Mods often pin an announcement with the date and time, including the time zone. Some post the AMA an hour early so questions can collect before the host arrives.
4. **Post it yourself**: AMAs are usually posted by the person answering, so the questions go straight to them. You can schedule the post up to 21 days ahead and add up to five co-hosts.
5. **Block out at least an hour**: Reddit suggests a minimum of one hour. Answer a wide range of questions, not only the easy ones, and give long, detailed answers.
6. **Answer as yourself**: Reddit says an AMA can't be done by someone else on your behalf or use answers copied from other interviews. Readers notice canned replies quickly.

Mods can do a little more to help. Reddit's moderator guide suggests pinning a comment on the AMA that confirms the guest has been verified, and making the post itself stickied and distinguished so it stays at the top of the community. It also suggests mods drop in a few questions of their own so the host isn't staring at an empty thread.

Write the title with care, because it's the first thing people see in their feed. Say who you are and what you're offering in plain words. If you want to check the length before you post, the [Reddit title counter](/tools/reddit-title-counter) shows how much room you have left.

## How people use AMA on social media

On Reddit, AMA is formal: it's a post type, a title convention and a scheduled event. Elsewhere it's casual. On TikTok, Instagram and YouTube, creators use it for a round of questions they'll answer in comments or in a follow-up video, which Know Your Meme notes vloggers were doing years ago. On X and Threads it often means a short reply thread. In DMs and group chats it's usually playful.

- Reddit title: "I'm a hospital night-shift pharmacist. AMA about what happens after 2 a.m."
- Reddit announcement: "AMA with our guest illustrator this Thursday at 7 p.m. ET. Drop questions below."
- Instagram story text: "Six months into living in a van. AMA, I'll answer tonight"
- TikTok caption: "Quit my office job to bake full time, AMA in the comments"
- Group chat: "Survived my first marathon, AMA (I can't feel my legs)"
- Reply under a creator's post: "Would you ever do an AMA about editing?"

> If someone asks you to "do an AMA", they mean they'd like you to answer open questions about your job, your hobby or something that happened to you. It's usually a compliment: they think your experience is worth asking about.

## AMA, AMAA, AUA and IAmA

A few close relatives show up on Reddit. Reddit's list of common expressions defines AMAA as ask me almost anything and AUA as ask us anything. The first warns that some topics are off limits. The second is for a group, such as a research team or a company's staff, answering together.

| Term | What it means | When you see it |
| --- | --- | --- |
| AMA | Ask me anything | One host taking open questions |
| AMAA | Ask me almost anything | The host wants to keep some topics off the table |
| AUA | Ask us anything | A team or group answering together |
| IAmA | I am a | The name of r/IAmA and the way many AMA titles begin |

Other Reddit shorthand often appears inside AMA threads. Hosts sometimes add a [TL;DR](/glossary/tldr) at the top of a long answer, and commenters hedge with [AFAIK](/glossary/afaik) or [IIRC](/glossary/iirc) when they add context. When readers sort the comments by Top, questions with the most [upvotes](/glossary/upvote) appear first, which makes them hard for a host to miss.

## When not to call something an AMA

An AMA sets an expectation: real answers, from the real person, to questions you didn't choose. If you can't meet that, call it something else. A brand that only answers friendly questions, or posts answers written in advance by a communications team, will usually get called out in the comments. Reddit's help center says an AMA has to be authentic, which rules out someone answering on another person's behalf.

It's also a poor fit when you can't stay. A post that collects hundreds of questions and gets a handful of one-line answers feels like a promotion wearing a costume. If you only have fifteen minutes, a plain Q&A post or a reply thread is more honest. And if the community you want to post in doesn't allow AMAs, respect that. The rules are in its sidebar, and the mods will tell you if you ask.

**Ready to host an AMA when**
- [ ] The community allows AMAs and the mods know you're coming
- [ ] You can prove who you are if the community asks
- [ ] You have at least an hour to answer
- [ ] You'll answer hard questions, not only easy ones
- [ ] You're answering yourself, not through a ghostwriter
- [ ] You have something people actually want to ask about

Some communities expect a history of genuine participation before they'll trust a newcomer with a big post, and many filter new accounts. Our guide to [Reddit karma requirements](/blog/reddit-karma-requirements) explains how those thresholds work and how to meet them without gaming anything.
