Twitter Community Notes: how they work, how to join, and what a note means for your posts

Updated 22 October 2026. Re-targeted at Twitter Community Notes: new sections on how notes work, how to sign up and add a note, why a note is not showing, rating impact, AI note writers, and what a note means for your post, all checked against the official Community Notes guide. Replaced an unsourced reach figure with a peer-reviewed study and removed claims we could not support.

Twitter Community Notes, short answer: they are short, sourced notes that volunteer contributors add under posts that might mislead. A note only appears when contributors who have disagreed in the past both rate it helpful, and Twitter says it does not choose which notes show. Anyone who meets the eligibility rules can sign up, starts by rating notes, and unlocks writing after earning a Rating Impact of 5.

The first half of this guide covers how the system works and how to take part. The second half is for creators: what attracts a note, and the writing habits that avoid one as a side effect of good writing.

How Community Notes work

• Contributors write and rate. Notes can be proposed by people or by AI note writers, including Twitter’s own Community Writer, but only human contributors’ ratings decide which notes show (Community Notes guide).

• It is not majority rule. A note needs agreement between contributors who have sometimes disagreed in their past ratings. This “bridging” design is meant to stop one-sided pile-ons.

• Statuses. Every note starts as Needs More Ratings. If enough contributors from different points of view rate it helpful, it earns Helpful and shows on the post; if they rate it not helpful, it never shows.

• The threshold is public. In the open-source scoring code, a note marking a post as potentially misleading needs a helpfulness score of 0.40 or more to earn Helpful, and only those notes are shown on posts.

• Statuses can change. A note can show and then disappear as ratings come in. Statuses lock after two weeks.

• Everything is open. All contributions are published daily and the ranking code is on GitHub.

How to join Community Notes

Sign-ups are open to everyone, expanding country by country. According to the sign-up page, your account needs:

• No recent notice of violations of Twitter’s rules.

• To have joined Twitter at least 6 months ago.

• A verified phone number from a trusted carrier that is not tied to another Community Notes account.

Admission is periodic. If there are more applicants than slots, Twitter admits accounts at random from country-specific waitlists, so people in bigger markets may wait longer. Once in, you contribute under an auto-generated alias that is not publicly linked to your Twitter account.

How to add a Community Note

1. Rate first. New contributors can only rate. Writing unlocks once you reach a Rating Impact of 5, which you earn when your ratings match the status a note later reaches.

2. Open the post. Tap the menu (the three dots) on the post and choose Write a Community Note.

3. Answer the questions. Say whether the post is potentially misleading and why, then write the context with sources. Only notes that call a post potentially misleading can show on it.

4. Wait for ratings. Your note goes to other contributors. If it earns Helpful, it shows on the post and your Writing Impact rises.

There are limits. Daily writing allowances depend on your Writing Impact and hit rate, new writers can write up to 3 notes a day on any one author, and writing ability is locked for a while if 3 of your last 5 rated notes end up Not Helpful.

Requests, AI note writers and Collaborative Notes

• Request a note. Anyone with a verified phone number can tap Request Community Note in a post’s menu, up to 5 requests a day to start. Top Writers see a post’s requests once there are enough of them.

• AI note writers. Developers can enroll an AI note writer through the AI Note Writer API. AI writers propose notes on requested posts and must earn admission like anyone else; they cannot rate notes.

• Collaborative Notes. An experimental feature in which a note request from an experienced contributor starts an AI-drafted note that improves through contributors’ suggestions and ratings. It is scored like any other note.

Rating impact, writing impact and Top Writers

Contributor scores are public on each alias profile. Writing Impact rises when your notes earn Helpful and falls when they reach Not Helpful. Rating Impact rises when you rate a note before it reaches a status and your rating matches that status. Both can go negative, and deleting a note does not erase its effect on your scores.

There is no official leaderboard in the guide. The nearest thing is the Top Writer badge, which needs a Writing Impact of 10 or more and a net helpful-note rate of at least 4 percent. Top Writers can write notes on images and videos and can see note requests.

Why a Community Note is not showing

• It is still Needs More Ratings, which is where most proposed notes sit.

• It reached Helpful, then lost it as more ratings came in. Notes can appear and disappear until the status locks after two weeks.

• It said the post was not misleading. Those notes are shown to raters but never on the post.

• It reached Not Helpful, or the ratings came from too narrow a group of contributors to count as agreement.

What a note means for your post

Twitter’s Community Notes FAQ says notes do not affect how a post is displayed or how its rules are enforced. Two things still change once a note appears:

• People share it less. A peer-reviewed study in PNAS (Slaughter and colleagues, September 2025) found that in the 48 hours after a note was attached, growth in reposts fell 46.1 percent and likes 44.1 percent. Early notes mattered most: notes attached after 47 hours had almost no effect (PNAS study).

• It stops earning. Twitter’s Original Content Rewards rules make content with a helpful Community Note ineligible for payouts.

If you think a note on your post is wrong, you can request additional review. Other contributors, not Twitter, re-rate it, usually within 24 hours, and the note stops showing if it loses Helpful status. A note is not a penalty or an enforcement label; those are separate and covered in Twitter’s negative signals and labels.

What makes a helpful note: Twitter’s own style guide

If you searched for Community Notes guidelines on style and tone, the official note-writing tips are short. Helpful notes:

• Cite high-quality sources.

• Are easy to understand.

• Directly address the post’s claim.

• Provide important context.

• Use neutral, unbiased language.

Unhelpful notes have missing or unreliable sources, sources that do not support the note, incorrect information, opinion or speculation, typos or unclear language, argumentative or biased wording, or harassment. The same list is a decent checklist for your own posts.

Five writing patterns that attract notes

1. Sweeping claims without provenance. “Studies show…”, “It’s been proven…”. Anyone with the actual research can flag them.

2. Viral hooks that strip context. A real finding stated so cleanly that the qualifying clause disappears.

3. Dated statistics presented as current. Old surveys and charts labeled “recent” are usually one search away from correction.

4. Satire that reads literally. On a quick scroll, a joke without a clear signal can be read, and noted, as a claim.

5. Plausible but wrong inferences from real data. Real chart, wrong conclusion; the writing introduces the error.

All five are forms of imprecise writing that put reach ahead of accuracy. The fix is not more disclaimers; it is writing precisely in the first place.

Why voice-first writing tends to avoid notes

A voice-first writer is one whose audience comes for their specific voice rather than for engagement-optimized content. That posture tends to protect against notes for three reasons:

• Sourced authority. “In the 200 deals we closed” is harder to note than “studies show”. The provenance is built into the voice.

• Fewer bait hooks. Engagement-bait openers are a category default, not a personal voice, so voice-first writers rarely use them. See why AI tweets sound the same.

• Calibrated certainty. Distinguishing “this is true”, “I think” and “I’ve seen this in three cases” is how thoughtful people talk, and it is exactly what makes a claim hard to note.

Five writing habits that pass the notes test

1. Source claims at the level you would for a peer who asks “where did you get that?”, and put the source in the post.

2. Calibrate certainty in the wording: “this is true” versus “I think” versus “I’ve seen this in”.

3. Put the year on statistics. “A 2024 survey of…” filters out most dated-stat notes.

4. Re-read for the claim that is vague enough to pass a quick read but specific enough to fail a careful one, and fix it.

5. Run the satire test: read the post as a stranger on a quick scroll. If the joke could be missed, make it unmissable.

What to do if you get noted

• Read the note carefully. Most are accurate enough to learn from. If it is right, correct the post in a follow-up or quote and move on.

• If it is wrong, request additional review rather than arguing in the replies. Reviews come from contributors, so a public fight looks defensive.

• Think twice before deleting. Screenshots outlive the post, and “corrected after a note” reads better than “deleted after a note”.

• Treat it as data. If the note caught a pattern you fall into often, fix the habit.

AI drafts and Community Notes

General assistants will happily produce sweeping claims, dated statistics and viral hooks if you ask for engaging posts, and they can state outdated facts with confidence. Whatever drafts your posts, the facts are still yours to check.

audenAI, the brain inside VoiceMoat, takes a different starting point: it learns from your own posts, so if your past posts source claims and calibrate certainty, its drafts start from those habits, and its Style and Stance checks flag drafts that drift from how you write. What it does not do is fact-check. The judgment about whether a claim is true stays with you.

Closing

Community Notes look like a moderation system; read closely, they are also a writing-quality test. The posts that get noted are rarely the ones with strong opinions (those get replies). They are the ones that strip precision for reach. The habits above are also the habits in finding your writing voice.

For niche-specific habits, Crypto Twitter for builders covers an audience that checks on-chain claims closely, and quote-tweets as voice moves covers the precision standard for quotes, where your words and the original sit in one screenshot.
