Product Case Studies

Each project is a small product case: a problem, a workflow decision and a shipped solution.

Chrome Web Store

Every browser extension I have shipped: the friction I noticed, what I designed, and what made it to the store.

Product case / 01

PinMate

An AI Pinterest title, description, tags and alt text assistant.

Chrome ExtensionJavaScriptAI APICreator workflow

Problem

Writing clear, searchable pin titles, descriptions, tags and alt text is repetitive and easy to get wrong.

Solution

AI-generated titles, descriptions, tags and alt text, plus product or affiliate link and product tag filling.

Product case / 02

Daily Habit Tracker

A lightweight tracker for diet, water, bowel, bladder and period logs.

Problem

Daily routines and small health records are easy to forget without a simple, low-friction place to log them.

Solution

A lightweight tracker that makes daily logging quick, with reminders and statistics that keep small health goals visible.

Product case / 03

FolderMark

A bookmark folder manager with search, color labels and a library health dashboard.

Problem

Bookmark folders grow messy and hard to search as the collection expands.

Solution

Search, color labels and a cleaner workflow that also finds duplicates and dead links and can undo a cleanup.

Product case / 04

StockMeta Assistant

AI metadata assistant for Adobe Stock creators.

Problem

Writing titles and keywords for many stock assets is slow and inconsistent.

Solution

A browser workflow that helps creators generate and organize stock metadata more efficiently.

Product case / 05

LingoFlow

Foreign website reading assistant for language learners.

Problem

Reading foreign websites is slow and tiring when every unfamiliar word breaks the flow.

Solution

Inline translation and comprehension help that keeps readers in the page, backed by a built-in offline dictionary and a saved vocabulary book.

Product case / 06

PromptVault

AI prompt management for power users.

Problem

Useful prompts often get lost across chat histories, notes and repeated workflows.

Solution

A personal prompt library for saving, tagging and reusing prompts across AI workflows, with variable templates and a command palette.

Product case / 07

SubtitleMate for YouTube

Auto-enables YouTube captions with translation or English auto-generated tracks.

Problem

Every time you open a YouTube video, you have to manually pick the subtitle language and playback speed from the player controls.

Solution

Set your preferred subtitle language and playback speed once in the extension; SubtitleMate automatically applies them to every YouTube video you open.

Product case / 08

ReplyPilot

AI email reply assistant inside Gmail.

Problem

Repetitive customer emails take up too much time, and reply tone is hard to keep consistent.

Solution

AI-generated replies inside Gmail with tone memory, keyword shortcuts and a configurable sign-off, for faster and more consistent communication.

Product case / 09

KeyAtlas

A shortcut search engine covering 5,000+ shortcuts for 200+ apps.

Problem

Keyboard shortcuts are useful, but they are scattered across different apps and hard to remember.

Solution

A searchable shortcut knowledge base that helps users find actions faster from the browser.

Product case / 10

Lucky Pick

A decision helper that settles everyday choices by random draw.

Problem

Small decisions (what to eat, what to do) often take minutes even when every option is acceptable.

Solution

Five random modes — dice, coin, wheel, draw and rock-paper-scissors; options can be weighted and results exported as images, with five UI languages.

Product case / 11

Pixel Color Picker

A browser color picker and palette tool.

Problem

Designers repeatedly leave the page to sample colors and copy values in different formats.

Solution

Pick page colors, build palettes and export CSS, JSON, Tailwind or PNG without leaving the tab, across 12 pixel-art themes.

Product case / 12

MiniCalc

A multi-theme calculator that lives in the browser.

Problem

When you need a quick calculation in the browser, opening a separate calculator or switching tabs breaks your flow.

Solution

A browser calculator with 130 switchable themes, an online theme store and optional click sounds — calculate without leaving the page.

Product case / 13

Magic Tarot

AI tarot readings with personal card interpretations.

Problem

Most tarot apps hand out the same canned meanings for every draw, so a reading never really speaks to your situation.

Solution

A browser tarot deck with 8 decks and 50+ spreads. Bring your own AI key for deep card readings, multi-turn Q&A and a daily fortune.

Product case / 14

TinyPalette

A compact color helper with HEX preview, RGB/HSL conversion, a built-in picker and a page eyedropper.

Problem

Previewing a HEX color or converting it to RGB/HSL usually means leaving the page or opening a separate tool.

Solution

A browser color helper that previews HEX, converts to RGB/HSL, samples colors from the page and copies any value.

Product case / 15

MindCapsule for YouTube

Turns YouTube videos into structured notes for faster review.

Problem

Knowledge videos carry a lot of information spread across a long runtime; manual note-taking misses the core takeaways.

Solution

MindCapsule uses AI to turn the captions into structured notes — a TL;DR, summary, key insights, a timestamped timeline and action items — ready to review any time.

For Visual Studio Code

Small tools built out of my own VS Code workflow, published on the Marketplace.

Product case / 01

Extension Sorter

Lists installed VS Code extensions by real install date, with theme filters and a link to the native details page.

VS Code ExtensionTypeScriptExtension APIDeveloper tooling

Problem

While publishing my themes from VSIX files I kept losing track of what I had just installed: VS Code mixes themes, tools and everything else into one installed list, and there is no way to ask what arrived last week.

Solution

A second view next to the built-in list: newest or oldest installed first, grouped by month, filterable to themes only, searchable, and honest about where each install date came from.

Web Tools

Self-built web tools that solve focused, repeatable problems in content operations and product workflows.

Pink Workbench

A cozy pink PWA workbench that bundles daily planning, English practice, habit tracking, mood journaling and an AI pet companion into one ad-free, offline-ready web tool.
