NagMeLater

NagMeLater is a personal productivity assistant that lives entirely inside WhatsApp. There is no app to install and no account to create: if you have WhatsApp, you can use it immediately.

You text it like a friend ("remind me tomorrow at 3pm to call John", "todo buy milk", "habit: gym at 7am daily") and it nags you at exactly the right moment. It understands plain language in English, Hindi, Hinglish and dozens of other languages, and voice notes work too.

What it does:

1. Reminders: one-off and recurring (daily, weekly, monthly, yearly, weekdays, custom intervals). Snooze, edit, cancel by texting.

1. To-do list: add, complete and organize tasks by text, with due dates and #project tags. Free and unlimited.

1. Habit streaks: "habit: go for a run at 7am daily", reply "done" when it fires, watch your streak grow.

1. Goals with deadlines: "goal: launch the site by Sep 1" and it tracks the countdown.

1. Daily accountability coach: a morning "what are your top 3 priorities?" check-in and an evening review of what got done.

1. Morning briefings and evening/weekly/monthly/yearly reviews: your day or week recapped, on your schedule.

1. Group reminders: nag family or teammates by alias ("remind @Priya tomorrow 9am to submit the report").

1. Context notes: "note Raj owes me $50", then "what do I know about Raj" later.

1. AI prioritization: text "prioritize" and it ranks what matters most right now.

1. Google Calendar meeting alerts: connect your calendar and get a WhatsApp nudge before every meeting.

1. Attach files: send a bill or document with a reminder and it points you back to the file when the reminder fires.

Pricing: first 5 reminders free, to-dos free forever. Then $1.99/month (launch price for the first 100 users, $4.99/month standard) or a $59 Lifetime Deal, one payment, yours forever.
