In 2023, Change.org integrated an AI-assisted writing tool into their platform. We found that access to the tool changed platform trends in petition text, but that outcomes (signatures and comments) did not improve... Excited that this paper is out, check it out! 🔗: www.nature…

AI Weekly's analysis →
  • A Cornell-led analysis of 1.5 million Change.org petitions found that an in-platform 'write with AI' tool reshaped petition text but did not improve outcomes.
  • After the tool rolled out, the share of petitions reaching one comment within 30 days of posting dropped 5%, with repeat writers seeing worse outcomes.
  • Titles clustered around a narrower vocabulary, with more petitions calling on readers to 'implement,' 'mandate' or 'urge' an action.

  • Cornell and Michigan researchers analyzed 1.5 million Change.org petitions to study the platform's in-product 'write with AI' tool.
  • Difference-in-differences analysis found AI access substantially altered petition language and increased homogeneity across the corpus.
  • Despite the stylistic shift, in-platform AI access did not improve petition outcomes, including among repeat writers before and after rollout.

  • Cornell researchers analyzed 1.5 million Change.org petitions and found that an in-platform AI writing tool made them longer and more homogeneous without improving outcomes.
  • After the tool's late-2023 rollout across the US, UK, Canada and Australia, the share reaching one comment within 30 days fell about 5%.
  • Among 4,611 repeat writers, the same authors produced longer petitions with worse outcomes once they gained AI access.

  • A Cornell and Michigan team analyzed 1.5 million Change.org petitions and found that in-platform AI access increased homogeneity but did not improve petition outcomes.
  • Among 4,611 repeat writers, those whose second petition was written with AI tended to produce longer appeals with worse outcomes than before.
  • The 'write with AI' tool substantially altered the lexical features of petitions at a platform level, according to the Nature Human Behaviour paper published 30 September 2026.
