🏗️ Work-in-progress (not actively maintained) 🏗️

An email course generator designed with effective, research-backed learning techniques in mind: spaced repetition (via an interval between email lessons), retrieval practice (quizzing and fill-in-the-blank), elaboration and reflection (writing exercises).

The first (and only) course is about Make It Stick. Signup is closed. I wrote about the implementation on my digital garden.

• main.tsx — HTTP handler (signup, verification, lesson completion, unsubscribe)
• cron.tsx — Interval that sends daily lessons to students who completed their current one
• db.ts — All SQLite operations (students table lives in account-scoped DB)
• email-helpers.ts — Email sending (verification, lessons, responses)
• html.tsx — HTML templates (signup form, confirmation email, lesson wrapper)
• lessons/ — 10 lesson content files + index

• The students table lives in the account-scoped SQLite database (not val-scoped)
• The cron should be kept inactive since the course is not actively maintained
• Previously this was spread across ~25 separate single-file vals; consolidated April 2026
