Handwriting with AI: One human in charge of the plan is enough to avoid similar stories

Of 427 stories written by 333 participants, 100% AI channels are more creative but more uniform. Conferring planning to a human keeps creativity and restores diversity.

When AI agents participate in writing, texts often gain in individual creativity, but at the risk of all looking the same. To find out where human intervention is most useful, researchers have divided writing into four stages inspired by the cognitive models of the writer — planning, writing, proofreading, revising — with each step receiving the work of the previous one as in a chain of transmission.

The plan, the best job for the human being

Using 427 stories produced by 333 participants, the study compares all-human, all-artificial, and hybrid chains. As in previous work, all-AI chains result in more creative but less varied narratives than human chains. Inserting a single person into an AI chain increases diversity, with an effect that depends on the role they are given.

It is to planning that humans bring the best balance: creativity remains at the level of AI, diversity increases and is maintained in the following stages entrusted to the machine, and the pleasure of writing is preserved. An argument for designing creative chains where humans set the direction rather than correcting at the end.
