I'm Katie Parrott. I make stuff with words.

Essays, apps, and agents — because words are magic.

Writer. Builder. Chronic overthinker.

I obsess over AI and work at Every, make things like Tastemaker, and spend too much time teaching machines to sound like me. Mostly I'm trying to figure out how technology changes how work feels — by sharing how it's changing how it feels to me.

What I'm Working On

Every

Staff Writer + AI Editorial Lead

I write, test, and build at the edge of AI, then turn what I learn into agency readers can use.

The Curiosity Gap

Author

My personal Substack. Longer, weirder, more confessional. The stuff that doesn't fit anywhere else.

Tastemaker

Creator

An AI writing tool that learns what good writing is to you, then teaches it back to you.

Bible Study

Side Project

A secular Bible study — reading scripture as literature, history, and weird ancient storytelling.

What I'm Thinking About

A running list of the questions that keep leaking out of what I'm publishing, testing, and building.

Current questions: Can I judge the frontier clearly while I'm busy wanting it to be miraculous? If a model can reproduce my voice, did I protect it or make it easier to flatten? Can AI make me feel more alive without taking over the rest of my life?
01

Models + susceptibility

Reviewing the tools I am rooting for

I test frontier models and write the practical guides, which means I have to separate what a tool can reliably do from the part of me already planning an entirely new life around the demo.

02

Writing + Tastemaker

Teaching AI my voice without sanding myself down

Tastemaker began as a way to teach AI my preferences. The live wire is whether specifying my voice protects its weirdness or gives the machine better instructions for smoothing it out.

03

AI + embodiment

Protecting the person the machine helped bring back

AI returned me to a kind of intellectual aliveness I thought I'd lost, then made it possible to neglect the sleep, meals, friendships, dog walks, and scripture that keep that aliveness attached to a human body.

Don't add an MCP to your website before a technical review

I gave AI agents a door into Tastemaker, then learned the door had more access than it should have. The connection is offline until its data-access design gets a thorough technical review. Turns out you check the locks before you invite the agent in.

Vibe Check: Opus 4.8—Anthropic Should’ve Rounded Up to 5

Opus 4.8 is the most complete model Every has tested yet: a jump back to the top on senior-engineering and writing benchmarks, stronger for everyday knowledge work, and good enough to make Claude tempting again—even if the app still lags the model.

Codex for Knowledge Work

A power-user's guide to turning OpenAI's coding agent into an operating system for knowledge work, with setup, workflows, and a seven-day starter plan.

The AI Pope, My Boss, and Me

I build the kind of AI Pope Leo XIV is warning about. I also work for the man making the optimistic case. So I put AI versions of all three of us in conversation, grounded in Magnifica Humanitas, After Automation, and my Working Overtime essays.

Connect your agent to Tastemaker

Tastemaker turns the passages you collect into a style guide that names your taste. Now you can connect that taste profile straight to your agent — Claude, ChatGPT, or Codex — with one-click OAuth, so it pulls your style guide and clips and writes in your voice.
