REPLACEMENT BRIEF

Can AI replace Todoist?
EDITORIAL ANSWERYESCatalog estimate
Projects, recurring tasks, reminders, and a Today view are a comfortable weekend build. Todoist's value is fast natural-language capture on every platform, offline sync that never loses a task, and light collaboration.
Create task/project tables, natural-language due date parsing, recurring rules, reminders, filters, and local notifications.

the prompt
Catalog estimateBuild 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.Copy or open in an agent

questions
Can AI replace Todoist?
Likely for the core workflow, based on an editorial catalog judgment. This entry is not a verified build yet; use the prompt as a starting point and validate the result against your own acceptance criteria.
How much does Todoist cost?
Todoist is listed at about $7/month (Pro, checked 2026-07-30), or $84 per year. This is a pricing reference, not evidence of a completed replacement or realized savings.
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.
