In Development
01 / What it solves
Emails to overseas users, with native-level tone
An AI email-writing tool for cross-border e-commerce and global SaaS, with built-in industry templates and tone calibration.
02 / How it got built in 7 days
"Eating your own dog food" isn't a slogan here — this tool was born in a 7-day challenge camp: the first version took exactly 7 days, and every iteration since has happened in public, inside the community.
D1-D2
Define the smallest usable scenario; cut every "someday" feature
D3-D5
Build the core path, publishing one build-log entry a day
D6-D7
Polish, launch, review — and let the pitfall list settle into the library
03 / Who it's for
- 01Indie developers building similar products in their own 7-day loops, who'd rather reuse than reinvent the wheel
- 02Newcomers who want a real build log as a reference — watch how a tool gets built in 7 days
- 03Indie developers who want to turn the community methodology into a daily workflow
