Writer is an AI-powered tool for checking and guiding content creators in organizations where voice and branding are essential. Its new feature CoWrite does that writing itself — but don’t worry, this isn’t quite the content apocalypse we’ve been worried about.

CoWrite is the latest in a new wave of tools that use large language models like GPT-3, but modify them using “fine tuning,” a common phrase but with a special meaning in the machine learning world. Basically it means giving the big, general model a specific set of content to imitate more closely than the rest of the language it understands — a bit like telling an image creation model to make a picture in a certain style by feeding it examples.
