Patient Intake

Design Lady LLC, independent, 2026, language technology. Physical dictionaries for Dominican Creole exist. No digital tool did — full stop, not "a bad one existed," none.

Diagnosis

A gap, not a redesign. The actual diagnosis was less "what's wrong with the current tool" and more "why has no one built this," which is its own kind of design problem: proving something is buildable fast enough that the absence stops being a reasonable excuse.

Prescribing Physician

Sole designer, sole builder, sole everything. Concept, data pipeline, interface, and store listing, sitting from empty folder to live install in a single sitting.

Treatment Protocol

Dosage Limits

Self-imposed timeline: under 3 hours, concept to live listing, as a deliberate constraint to prove the build pattern (solo, AI-assisted, same-day) rather than an externally imposed deadline. Deprioritized: audio pronunciation for every entry, scoped out of v1 to hit that window, flagged as the clear v2 priority.

Clinical Trial Artifacts

The data pipeline that turned scanned dictionary pages into verified, structured entries.

Three-step data pipeline diagram: scanning a physical dictionary page, OCR-extracting raw entry text, then cross-verifying it with Claude and Gemini to produce structured, verified entries, with flagged entries queued for manual review.

The shipped extension itself: the onboarding/about screen plus all five main screens.

Six screens from the Kwéyòl Donmnik extension side by side: an onboarding/about screen with the extension's branding and a Rate this extension prompt; Today, showing a word-of-the-day card, a Did You Know fact, and a streak counter; Dictionary, showing a search field over 8,550 entries with English-to-Kwéyòl and Kwéyòl-to-English toggle; Phrases, a scrollable list of 147 common phrases with tap-to-copy; Alphabet, a gold card grid of the 32 letters filterable by type, with flip-to-example cards; and Grammar, a guide covering word order and verb tense markers with example sentences.

Efficacy Results

Adverse Reactions Disclosed

The under-3-hours constraint, while a strong proof point, meant zero user testing before launch. Real usage since has surfaced a handful of entry-formatting inconsistencies from the OCR pass that a testing round would have caught, now queued for a cleanup pass.

Side Effects

Obsessive kerning, extreme satisfaction with line-height, sudden desire for custom illustration, heightened expectations for every subsequent project.

Common Adverse Reactions

Rapid promotion within the organization. Extreme stakeholder satisfaction. Accidental virality on social platforms.

Rare Reactions

Uncontrollable urge to fix every font on the internet. Spontaneous applause during presentations. Development of a "refined palette."
