Content Model Designer, AI at Thumbtack


I’m a content designer and UX writer. AI can write a thousand words a second. I decide which ones people should actually read, and which ones they shouldn’t. I’m a former school principal, English professor, and curriculum designer (and still a teacher at heart).

How I think

When we design content with AI tools, we don’t have to lose our voice or our brand. We use these tools to push our thinking and build the structure behind every word. Then we hold AI to the same bar as any good writer: to be honest, to be clear, and to know when to be quiet.

And when we want to write with pencils and paper, we do.

How I work

Good content still starts
with knowing your audience

As an educator, I’ve learned that being understood matters more than sounding smart. We don’t need fluffy language or corporate jargon. People crave simplicity. When we know what our audience needs, we can give them exactly that.

Listen

User interviews and research to find the real pain points before writing a word.

Structure

Content models, taxonomies, and voice and tone guides that keep every screen consistent.

Write

UX copy, style guides, and AI prompts. Keep what’s necessary, toss what’s not.

Evaluate

Usability tests, metrics, and evals that show whether the words are actually doing their job.

What people say

[Sarah] had an excellent quarter. Call Summaries v2 stands out, both for the prompt work and for everything [she] put in place to support it: the eval workflow, the changelog, the prompt crits, and a handoff doc that makes it easier for others to carry the work forward.

When I’m not creating better content systems…

I’m a part-time homeschooler, full-time mom, and California native. Today, I live in Texas where I enjoy creating vegan southern desserts for my family.
