Shichuan started as a jewelry content generator. One question — 'Why not full pipeline for all categories?' — turned it into a 7-domain e-commerce content platform with AI images, XHS text cards, platform-aware formatting, client-side video, and 95%+ margins at 99 RMB per suite.

Most TTS gives you a voice. Doubao claims to give you emotions. I ran a systematic experiment — 30 audio samples across stock voices, cloned voices, and 3 emotion control methods — to find out what actually works. Listen for yourself.

Complete integration guide for Volcengine Seed ASR bigmodel — the submit-then-poll REST API for Chinese speech-to-text. Console setup, two-step async flow, fallback chain pattern, cost tracking, and 8 gotchas about v2 vs v3 APIs that will save you a day of debugging.

Complete integration guide for Volcengine Doubao Seed-ICL 2.0 — voice cloning, natural language emotion control via context_texts, per-sentence multi-call synthesis, NDJSON response parsing, and 7 gotchas that will save you hours of debugging.

A runbook you can hand directly to Claude Code to execute. Covers sing-box multi-protocol deployment (VLESS-Reality / Hysteria2 / TUIC-v5), SSL certificates via Cloudflare DNS API, nginx subscription server with dynamic traffic stats, and Clash Verge / Shadowrocket client configuration. Replace the placeholders, hand it to your agent, hit go.

A deep dive into ÉLAN's 10-section prompt system, the VANITY_DESIGN_INSTRUCTIONS that make luxury look incidental, SSE streaming architecture, caption generation with 3 style templates, and the real cost breakdown — output image tokens dominate virtually all of the per-session cost.

I sent 5 research agents out simultaneously to study Xiaohongshu photo trends, pose libraries, caption formulas, luxury aesthetics, and competitor UX. 42 data points came back. From that research, I designed a catalog of Muse Cards — curated photoshoot packages that encode everything from scene and pose to color grading and caption. Here's the full design process, one card dissected to its atoms, and honest notes on what works and what doesn't.

Miaoya Camera hit 600K DAU and lost 94% within a year. Most AI photo apps sell novelty — but novelty decays. I wanted to try something different with ÉLAN: curated 'Muse Cards' that encode a complete visual formula for effortless luxury, so users get photos and social captions in 3 taps. Here's what I've learned so far.

ÉLAN's target user takes photos on her phone and posts from her phone. A web-only product misses the core use case. Here's what actually happened when I brought a Next.js app to React Native via Expo — what transferred, what didn't, and the SSE streaming hack that saved the project.

A friend pitched 'cloud try-on for jewelry.' Deep research killed the plan in 20 minutes. But the same Gemini pipeline from ÉLAN could generate editorial-quality product content — studio shots, material constellations, color DNA pages — for a fraction of what merchants pay photographers. One day later, Shichuan was live.
