AI Writing App — Design System

Mobile-first product design for an AI writing assistant: keyboard interactions, flow design and a visual system explored end to end before a line of production code.

The problem

AI writing tools live or die on interaction detail — how suggestions appear, how the keyboard behaves, how much the interface interrupts the act of writing.

What we built

  • Mobile-first flows for assisted writing, revision and suggestion review.
  • Keyboard-aware interaction patterns prototyped in Figma.
  • A visual system with reusable components and type/colour scales.
  • Interaction states for empty, loading, error and long-content cases.
  • Handoff-ready specs so engineering and design share the same language.

Outcome

A design archive that shows how we approach AI product design: prototype the interaction first, then build the smallest system that supports it.
