Anyone can sign up to become contributors. Accounts must meet a few criteria to be eligible. Learn more here.

We want everyone to feel comfortable contributing to Community Notes. Because of that, all contributors get a new, auto-generated display name (or alias) when they join Community Notes. These aliases are not publicly associated with contributors’ Twitter accounts, so everyone can write and rate notes privately.

You can learn more about aliases here.

Any Tweet can receive a Community Note.
Notes that have been rated helpful by enough contributors from different points of view will appear directly on Tweets. Beyond that, notes do not affect display of Tweets or enforcement of Twitter Rules. Our current focus is gaining confidence that Community Notes produces context people from different points of view find helpful and informative.
No. We believe there’s no single blanket tool or intervention that can solve the problem of misleading information on the internet. Our aim is to learn how Community Notes may complement our existing efforts.

We believe regular people can valuably contribute to identifying and adding helpful context to potentially misleading information. Many of the internet’s existing collaborative sites thrive with the help of non-expert contributions — Wikipedia, for example — and, while it’s not a cure-all, research has shown the potential of incorporating crowdsourced based approaches as part of a broader toolkit to address misleading information on the internet, for example:

In our pilot test of Community Notes, we evaluated notes that would be shown on Tweets, and have found:

  • The majority of people surveyed on Twitter found notes helpful
  • People in surveys were 20-40% less likely to agree with the substance of a potentially misleading Tweet after reading the note about it, compared to those who saw a Tweet without a note
  • Most notes have been rated highly on accuracy by professional reviewers; it has been rare to find a note that reviewers agree is inaccurate

The people on Twitter span a wide gamut of backgrounds and experiences, and we believe that, working together, they can help create a better-informed world.

The people on Twitter span a wide gamut of backgrounds and experiences, and we look forward to everyone being able to contribute to this challenge.

All Community Notes' data are made publicly available on the Download Data page of the Community Notes site so that anyone has free access to analyze the data, identify problems, and spot opportunities to make Community Notes better. You can learn more about our data here.
A wealth of relevant knowledge exists beyond Twitter’s virtual walls, so we are drawing on external research and collaborating with a variety of groups and organizations for their expertise and input. In building Community Notes, we’ve drawn on input from academic advisors whose expertise includes crowdsourcing, online juries, political science, polarization and more. Their input has helped us shape what Community Notes is today, and will going forward. We’re also collaborating with AP and Reuters as part of our analysis of the helpfulness & quality of information elevated by Community Notes.
Tweet authors with Community Notes on their Tweets can request additional review or report notes. Learn more.

All contributors and all Community Notes contributions are subject to the Twitter Rules. Failure to abide by the rules can result in removal from the Community Notes program, and/or other remediations.

If you believe a note may have violated the Twitter Rules, you can report it by clicking or tapping the ••• menu on a note, and then selecting “Report”, or by using this form.

Contributors who consistently write unhelpful notes may also have their ability to write new notes temporarily locked.

Community Notes will only be successful if the context it produces is found to be helpful and appropriate by a wide range of people with diverse views. This obviously won’t be true if it can be taken over by a single group or ideology, or used in an abusive manner. We believe this is possible, and will be experimenting with different mechanics and incentives than Twitter to help make it happen. Learn more about how we are approaching these issues here.
