New Font Lets People Read, AI Can't

Summary

- Scientists have designed a font that looks ordinary to people but tricks AI into misreading it.
- The design uses tiny variations in letter shapes that stay readable to the eye but fool machine learning models.
- Tests show popular AI text recognizers and large language models fail to interpret the text accurately.
- The technique could block AI from harvesting or training on private documents and copyrighted material.
- It represents a new form of digital privacy tool that balances human readability with AI resistance.

- As AI systems read more online content, they can also scrape private files if they can read them.
- A font that hides text from AI gives users a way to keep personal notes and sensitive documents out of machine reach.
- It also limits how easily AI can learn from copyrighted works, which could help authors and creators control their content.
- If adopted, this could change how we share documents online, making it harder for AI to copy or summarize them without permission.
