Fern Writer | Fern Documentation

Fern Writer is available in beta. For access, reach out via Slack or support@buildwithfern.com.

Coming soon: GitHub integration for automatic updates when your repo changes.

Fern Writer is a technical writing agent powered by Devin AI that keeps your docs aligned as your product evolves. You can request documentation updates by tagging @Fern Writer, and it drafts targeted edits to your documentation via GitHub pull requests.

Fern Writer understands Fern components and your custom styling, learns your writing style, and makes edits that fit your existing content organization. You can customize its behavior to match your team’s style guide and workflow.

Setup

To start using Fern Writer, add it to your Slack workspace (you must be a Slack admin) and invite it to channels where your team discusses documentation.

Usage

In channels where Fern Writer has been added, tag @Fern Writer and describe the change you need. Fern Writer only responds when directly tagged, and will create a pull request and reply with a link.
