Work
Every product on the studio's roster started the same way: I built it for myself, kept using it, fixed what broke, and at some point it was good enough that other people could use it too. This page lists what's currently public, and what's in the workshop.

A working library of AI prompts for people who use AI to actually make things — images, video, music, text. Every entry has been personally run through the model it claims to support, with the variables exposed so you can adapt it to your own situation. Not a marketplace. Not a comprehensive index. A curated reference, opinionated about what counts as a good prompt.
Alongside the library, PromptCraft ships a small set of free in-browser prompt generators — short, focused tools that compose a working prompt for a specific model from structured inputs. Currently covering Midjourney, Flux, Stable Diffusion, Ideogram, Suno, the major chat models (ChatGPT / Claude / Gemini), and the major video models (Sora / Veo / Kling / Runway / Pika). Browser-only, no signup, no upload of your work.
The library is bilingual (Traditional Chinese and English) and the codebase is one Next.js app deployed on Cloudflare Workers. PromptCraft has a small Pro tier for users who want to save presets and use AI-assisted prompt enhancement; the free tier covers the library and the generators in full.

A Bloomberg-style terminal for Taiwan equities, built for active investors who got tired of clicking between fifteen tabs to make a decision. Each stock page puts candlestick chart, computed indicators (KD / MACD / moving averages / Bollinger), institutional flow chips, big-shareholder distribution, recent news, calendar events, and an AI-generated commentary on a single screen — designed dense, red-up green-down, tabular numerals, the way professional traders expect to read data.
The differentiator is the AI layer. A four-factor decision score (technical 40% / fundamental 30% / sentiment 15% / chip 15%) ranks every stock daily. An LLM generates a “chip story” — turning the numbers into a paragraph that says what the market is actually doing in plain language. Twenty-three investment-master personas (Buffett, Munger, Lynch, local Taiwanese investors like 張錫 / 陳重銘 / 雷浩斯) can be queried for their take on a specific holding, with their thinking framework applied to live data.
Built on the same stack as PromptCraft (Next.js + Cloudflare Workers + D1), with a Taiwan-specific data pipeline: TWSE / TPEx OpenAPI for market data, FinMind for fundamentals, cnyes / Yahoo for news, TDCC for shareholder distribution. Around 30 cron jobs keep things current. Free tier gives you the dashboard, indicators, and rule-based summaries; AI commentary and master consultations have small daily quotas to keep API costs sustainable.
Other tools are at varying stages of “built it for myself, deciding whether to ship.” They surface here when they're ready — the studio runs on shipping things that are actually done, not pre-announcing things that aren't. The list at any given moment is small by design.
If you'd like to be told when something new ships, the most reliable channel is emailing the studio and asking. There's no mailing list and no announcement feed yet — just a person who responds when there's news worth sharing.
The two-part test: I have to use the thing every week myself, and the thing has to be genuinely better than the existing alternatives. Anything that can't pass both gates stays in the workshop. Most ideas don't pass. The point of the studio isn't to ship many products; it's to ship products that hold up.
When something does make it onto this page, it ships with honest framing. If a feature is half-baked I say so. If a product is content-light I note the gap. The site you're reading this on is part of that posture: a studio site, not a marketing site.
