Projects
Built by Silas Lee · 文西 while learning how to build, ship, validate, and archive small products in public.
This page keeps current work visible while giving older experiments a cleaner home. Some projects are live, some are retired, and some are only useful because of what they taught.
Featured
World Cup 2026 match times in your own timezone, with calendar downloads.
A small web tool for checking World Cup 2026 match times locally and exporting games to a calendar.
Lesson: Specific public utilities are easier to explain than broad productivity systems.
Local-first prospect notes and follow-ups for manual outreach work.
A Chrome extension for saving manual outreach context, follow-up cards, and local templates without scraping or background tracking.
Lesson: Some useful tools should stay close to the user's existing workflow instead of trying to replace it.
Live
A focused expiry tracker for skincare and beauty products.
A small iPhone utility for tracking skincare and beauty product expiry without turning the job into a broad beauty workflow.
Lesson: A compact utility can be more honest than a product that pretends to own an entire category.
A small decision tool for reviewing recurring subscriptions.
A compact iPhone app for making subscription renewal decisions with a clearer record of personal value.
Lesson: Everyday decision tools need a very sharp repeat-use moment to keep earning attention.
Experiments
Experiment
A low-risk decision environment for AI agents.
Lesson: Agent experiments need clear rules, fair-play boundaries, and humble claims before they deserve benchmark language.
Experiment
A county foreclosure notice PDF-to-CSV desktop prototype.
Lesson: Template-heavy products slide into service work unless the scope stays brutally narrow.
Experiment
A tiny web tool that turned one tweet into three reply options.
Lesson: If general AI already covers the baseline, convenience alone is not enough of a wedge.
Retired
Retired
Incident diagnosis for structurally broken CSV files.
Lesson: Sharper product boundaries tend to outperform broad data-platform ambition.
Retired
Local-first CSV auditing with reviewable exports and audit trails.
Lesson: Trustworthy workflows still need a much stronger pain signal to survive.
Unfinished / Ideas
Unfinished
An early offline-first CSV and Parquet audit direction.
Lesson: Dead branches can still be useful roots for better products later.
