Substack adds an AI detector to help spot blogs written by no one
What happened
Substack introduced an AI detection feature that scans posts, notes, replies, and comments to estimate how much content may be generated or assisted by AI. The feature is powered by Pangram, an AI detection company, and is now available on the Substack web platform and iOS app, with an Android version coming soon.
Why it matters
This move addresses growing concerns over AI-generated content muddying online discourse and reader trust. By flagging potentially AI-written text, Substack provides a tool to help users judge the authenticity and originality of what they read. For writers and readers on the platform, this changes the dynamic by introducing transparency around AI involvement in content creation, which can pressure authors to clarify or reconsider their use of AI tools.
For publishers and independent writers, it raises the cost of invisibly relying on AI, as detection could alter audience trust or perceived credibility. It also sets a precedent that other content platforms might follow by embedding AI detection to manage authenticity without outright banning AI-generated work.
What to watch next
The accuracy and sensitivity of the detection tool will be critical. Watch for how well Pangram’s system differentiates between fully AI-generated content and text lightly assisted by AI edits or suggestions. Also, monitor how Substack’s community reacts—whether this nudges more transparency or fuels disputes about content creation methods.
The Android rollout timing and potential expansion of detection to more content types or integrations with moderation systems will further clarify whether AI detection becomes a standard trust tool or simply another flag creators need to navigate.
