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.

the prompt
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.

questions
Can AI replace Todoist?

Yes. A competent AI coding agent (Claude Code, Codex, Cursor) can build a usable personal Todoist replacement in one session with the prompt on this page. It runs on your own machine or server with no subscription.

How much does Todoist cost?

Todoist costs about $7/month (Pro, checked 2026-07-30), which is $84 per year. That's what you save by replacing it with one prompt.

What do I lose by replacing Todoist?

Honestly: native apps; offline sync; collaboration; reminders reliability; integrations; years of UX polish. If any of those are load-bearing for you, keep paying.

Is there an open-source alternative to Todoist?

Yes — Vikunja (Open-source task/project management app suitable as a Todoist-style alternative.). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
