The Augmentalist - a collection of essays where I think out loud about humans, machines, and how we live and work between them.

First post: how tools begin as mirrors of our intent and end as expectations we no longer notice. augmentalist.org/2025/human-a...

StepWrite is one step toward making high quality writing possible anywhere ideas strike. We are excited to see how it can inspire new ways of creating on the move.

How It works:

• Plans the writing flow before you speak
• Asks adaptive follow-ups based on your answers
• Keeps tone, facts, and earlier context
• Lets you skip, revise, or finish anytime
• Supports progressive discovery — you don’t need to know exactly what to say before starting

What we found:

With 25 participants, StepWrite:
• Cut editing effort by 7× vs dictation
• Lowered workload on all NASA TLX measures
• Matched ChatGPT in usability, fully hands free
• Produced longer, more coherent, richer drafts
• Improved idea organization and narrative flow

Why it matters 📝

Writing while walking, cooking, or commuting is mentally taxing.

Dictation makes you plan and say everything at once, which often leads to messy drafts.

StepWrite splits the process into small, answerable steps so you can stay in flow anywhere.
