Helping writers write

A work in progress, the Writing Buddy app stays in its lane as a writing assistant, not a writer.

In this personal project, I’m interested in furthering the conversations around supporting humans’ natural cognitive strengths through application design and the intentional use of genAI. The project leverages my experience designing interfaces that integrate genAI while I build skills with some of the newer tools.

I’ve written more about my thinking on this subject here and here.

App welcome screen invites a writer to create their first project.
Overlay prompts writer to begin a new project by providing a title and selecting a writing style.

I started out with a design brief in Figma Make. After a few iterations, I finessed the screens in Figma Design and began prototyping. This helped slow the process down while I run the constrained version by different writers to stress-test my assumptions.

I avoided spending too much time on aesthetics, since the main focus was the interface and flow. Two items I spent a little extra time on were setting up dark and light modes in the prototype version and the logo, which I reshaped from simple open book to something just a little bit more wing-like.

Overlay shows a list of writing styles to choose from, including General, Academic/Professional, Journalist, Novelist, and Poet.

The writing style picker is one of the steps I’m continuing to think about. Testers have suggested additional or alternative writing styles, but I’m starting to think that a lot of these complex decision points can also benefit from a ‘user journey’ approach: a writer just starting with the app would get an updated but still simple list; as their usage began to signal comfort with the app, a new option would allow them to build a fully custom writing style.

In fact, there are a number of points in the app that can begin with fixed options and then progress to open preferences that take more advantage of an LLM’s true potential.

Generative AI feedback in an overlay on the phone screen

In this version, feedback begins with a synopsis, followed by a full breakdown*.

If the writer tries to excessively hand off thinking, the app politely pushes back.

*The next version explores an interface that allows the user to specify the type of feedback they’re looking for and invites further conversation.


Premature requests for feedback are an obvious place to intercept cognitive handoff. A subtler signal might be a shrinking discovery phase, based on a writer’s earlier patterns, of how quickly a project is concluded. The application could also encourage more variety in thinking by suggesting new workflows.

Home screen now shows two active projects with details like date and word count.
Mobile screen showing a history of feedback to the writer's project. There is space for the writer's notes and options to dismiss an item from the list.

Tackling this project has been a convergence of my interests in human cognition, curiosity about the new tools, and as a writer, my desire for technology to, well, get out of my way until I’m actually ready to ask for help.
