Community notes
Reader-written context that attaches to a post when it might mislead. Notes only show up after a diverse group of contributors agrees the note helps.
What it is
Community notes are reader-written context that attach to a post when that post might mislead. A note only goes live after a diverse group of contributors agrees the note is helpful — "diverse" meaning people who normally rate things differently. So a note is something both sides find useful, not just one camp's edit.
How to use it
Tap · → Suggest a note on any post. Write what's missing or inaccurate, with a source link. Notes have to be sourced; "this is wrong" without evidence won't pass review.
Other contributors rate suggested notes as Helpful, Not helpful, or Needs work. We weight ratings by the diversity of raters, not just the count.
If a note crosses the threshold, it appears under the post for everyone — alongside a small "Why this note" link explaining the rating math.
Why it matters
Centralized fact-checking is slow and gets accused of bias — sometimes fairly. Community notes shift that work to a transparent, source-cited process where the bar is "people who disagree on most things both think this helps." Honestly, it's the closest thing we have to trustworthy correction at internet speed.
