Making Prompt Engineering Invisible

Prompt crafting is a skill most people lack but everyone needs. The interface should close that gap — automatically.

Note · 01

Most people using AI tools get mediocre results — not because they lack intelligence, but because they lack vocabulary. Prompts are the interface between human intent and machine output, but nobody teaches you how to write them.

Note · 02

The market has thousands of "prompt libraries" — static collections of copy-paste text. Prompty was designed around a different insight: the best prompt isn't stored somewhere, it's generated from context. The design challenge was making that generation feel instant and effortless.

03// What was designed
01

Prompt Builder

Designed the structured prompt composition interface — variables, role templates, and chain-of-thought scaffolds for power users and beginners alike.

02

Cross-Platform Sync

Built the multi-platform connector UX. 55+ integrations with a single source of truth for your prompt library.

03

AI Enhancement Layer

Designed the AI-assisted improvement flow — automatic rewrites, clarity scoring, and output prediction before you run a prompt.

04

Sharing & Discovery

Created the community prompt marketplace — forking, remixing, and rating flows for a growing library of 100k+ expert prompts.

05

Version Control

Designed prompt version history — diff views, rollback UI, and A/B testing patterns for iterative prompt engineering at scale.

06

Analytics Dashboard

Built the usage analytics dashboard — token cost tracking, output quality metrics, and performance comparisons across AI models.

Prompty — cross-platform prompt optimization in context.

Designed for the browser, the web, and mobile — one creation experience everywhere.

From Intent to Optimised Prompt

The core interaction is deceptively simple: the user types what they want to achieve, and Prompty produces the optimal prompt for the platform they're using. But the design behind that interaction involved mapping 55+ platform vocabularies, designing a progressive disclosure flow that hides complexity until it's needed, and creating a feedback loop so users could see their prompt improve in real time. I ran 12 prototype tests before the creation flow felt inevitable.

Cross-Platform Context Detection UI

When the browser extension activates, the user needs to know immediately which AI platform has been detected and how their prompt will be optimised differently. I designed a compact detection panel that communicates platform context, active template category, and enhancement mode in under two seconds — without interrupting the user's existing workflow. The visual language pulls from the host platform's own aesthetic so the extension feels native, not foreign.

Template Library Information Architecture

A library of 100k+ prompts is useless without structure. I designed the information architecture around use-case clusters (not platform categories) because users think in terms of "I want to write a cold email" not "I need a GPT-4 prompt." The library uses progressive refinement — broad category first, then platform, then tone — with a "quick-fill" shortcut that skips the hierarchy for returning users.

"Incredibly swift at turning ideas into real product — building the prompt engine from the ground up."
