Simply

A minimalist to-do list with tags, categories, a calendar, and a context-aware AI assistant. No accounts, no passwords — just a name on first visit.

Stack

• Next.js (App Router, TypeScript, Tailwind)
• SQLite via Turso (libSQL) — same SQLite you know, but deployable on Vercel's serverless functions.
• Groq for the AI assistant (llama-3.3-70b-versatile)

How identity works

There's no login. On first visit you're asked for a name, which generates a random id stored in localStorage (and a cookie as backup). That id tags every row you create in the database. Clearing browser storage effectively "logs you out" of that device — there's no recovery flow, by design, since there's nothing to recover.

Features

• Quick add — type a task, use #tag and @category inline shorthand, optionally set a due date.
• List view — grouped into Overdue / Today / Tomorrow / This week / Later / No date.
• Calendar — month view with a dot on any day that has open tasks; click a day to filter the list to it.
• Assistant — a chat panel that can see your current tasks (titles, tags, categories, due dates, completion state) and answer questions about them. It's read-only by design — it won't add or edit tasks for you, only talk about what's there.
