The AI-assisted solo technical writer

Devin, the sole technical writer at Fern, utilizes AI tools to efficiently manage and produce a vast amount of documentation for Fern's open-source tool, which generates API documentation and SDKs in nine languages. With frequent releases and daily feature shipments, Devin leverages AI tools such as Fern Writer and Claude Code to streamline documentation processes, handle routine updates, and experiment with content structures. Fern Writer, integrated with Slack, assists in drafting documentation by analyzing context from Slack threads, while Claude Code allows for local iteration and refinement of content. Despite AI's assistance, Devin remains actively involved in reviewing and editing each page, ensuring that the documentation maintains coherence and accuracy as the product evolves. The AI toolkit continues to expand, enabling Devin to focus on higher-level editorial judgment and information architecture, although AI is not yet capable of autonomously managing complex documentation needs.
