Can AI replace Todoist?

A personal task app with projects, recurring due dates, filters, and reminders is a one-sitting/weekend build; collaboration and sync polish are the product moat.

Hidden costs: Business charges per member; taxes can apply.

02Could AI build it for you?

The core job: Create task/project tables, natural-language due date parsing, recurring rules, reminders, filters, and local notifications.

What a working version needs:

  • local or hosted database
  • date parser
  • notification channel
  • optional mobile/desktop wrappers

Strong yes; familiar product where feature creep is the real limit.

03What you'd give up

  • native apps
  • offline sync
  • collaboration
  • reminders reliability
  • integrations
  • years of UX polish

They pay because task capture must be fast everywhere and reminders cannot miss.

Apple Remindersfree

Things minus the polish tax, provided every device in sight has an Apple logo

prompt.txt
Build me a personal task manager to replace Todoist. Requirements:

- A local web app: Node + Express + better-sqlite3, server-rendered, binds to
  localhost only. Keyboard-first: n for new task, x to complete, / to search.
- Quick-add parses natural language with chrono-node: "call Sam tomorrow 4pm
  #home p2" sets due date, project, and priority in one line.
- Projects via #tags, priorities p1-p3, free-text notes on any task.
- Recurring tasks stored as rrule strings ("every 1st", "every mon,thu");
  completing one schedules the next occurrence.
- Views: Today, Upcoming (next 7 days grouped by day), and per-project. Overdue
  tasks pinned red at the top of Today.
- Reminders: node-cron checks each minute and pushes due tasks to my phone via ntfy
  (topic in .env), plus a 7am digest of today's list.
- A t add "..." CLI for capture from any terminal.
- No accounts, no telemetry, everything in one SQLite file I can back up.
- Out of scope: collaboration, native mobile apps, and offline sync. Phone access
  is ntfy notifications, that is the trade.
- README: ntfy app setup on the phone and where the DB lives.
