Complete Capabilities Guide

Everything Aster does for you directly on WhatsApp.

Say goodbye to clunky apps and forgotten spreadsheets. Aster is the AI personal assistant that organizes your entire life — tasks, proactive follow-ups, expenses, massive files, and memories — in a single natural conversation.

No credit card required • No mobile app installation needed

Module 01 • Daily Automation

Smart Reminders, Medication & Birthday Alerts

Speak or type on WhatsApp just like you would to a friend. Aster calculates your profile's exact timezone, schedules one-off or recurring triggers, and notifies you with clear structured text and natural AI voice notes.

How it works behind the scenes:

  • Individual Profile Timezone: Whether you travel or a family member lives abroad, alerts trigger in the exact local time of that monitored profile.
  • Complex Custom Recurrence: Specific weekdays (e.g., Mondays and Thursdays), monthly dates (every 10th), or day intervals (every 3 days).
  • Medication with Dosage Tracking: Treatment schedules with regular intervals (e.g. every 8 hours for 7 days) and prescription renewal alerts.
  • Birthdays with 7-Day Advance Notice: Advance warning one week ahead so you have time to buy gifts or book reservations, plus on the day itself.
  • Batch Creation via Voice: Send a single voice message with 4 different commitments; Aster extracts and schedules all 4 independently.

Real requests you can send right now:

Remind me to take 20 drops of dipyrone every 6 hours until Sunday

Module 02 • The Exclusive Game Changer

Continuous Follow-ups: Your Relentless Personal Secretary

Exclusive

Standard apps send a weak push notification that you swipe away and forget forever. Aster's proactive secretary won't let things slip: it actively follows up at set intervals, respects your night rest, and understands natural conversational replies.

Why this transforms your productivity:

  • Proactive Follow-ups Every 4 Hours: Aster doesn't just notify; it insists: 'Did you manage to complete this task?'
  • Strict Daytime Window (08:00 to 21:00): Never disturbs you at night. If a nudge lands at 10 PM, Aster quietly holds it until 8 AM the next morning.
  • Interactive Action Buttons: Delivered directly on WhatsApp with instant action buttons [Done] and [Postpone], letting you resolve or postpone tasks in a single tap.
  • 100% Conversational Resolution (Zero Regex): Reply however you want: 'done yesterday', 'client approved', or 'nudge me tomorrow at 2 PM'. AI understands instantly.
  • Batch Resolution without Spam: If you say 'finished all 3 renovation tasks', it closes all three and confirms in a single consolidated message.

Commands you can test right now:

Aster, add a follow-up: need to check Carlos's proposal feedback
Task follow-up: take the car to replace brake pads
I already took care of Carlos's proposal and the brakes this morning!
Postpone this follow-up until tomorrow at 3:00 PM
Proactive WhatsApp Follow-upWindow 08:00 - 21:00

Module 05 • Second Brain

Memories: Granular Questions on What You Saved

Unlike static note apps, Aster doesn't just dump raw text back at you. If you saved a long citation, household rules, or a 15-step family recipe, ask about any specific detail and it extracts the exact answer.

Surgical questions on complex memories:

Select a scenario to see semantic extraction in action:

You saved Steve Jobs's entire Stanford commencement address:

"Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart... Stay hungry, stay foolish."

Instead of asking for the whole speech, ask a targeted question:

In the Stanford quote I saved, what did he say about being naked?
What is the final sentence of the Steve Jobs quote?

In the Stanford quote I saved, what did Steve Jobs say about being naked?

10:15
Granular Memory

In the quote you saved, he states that remembering your own mortality eliminates the fear of loss, because: 'You are already naked. There is no reason not to follow your heart.'

Module 06 • Effortless Collaboration

Smart Shared Lists for Couples and Families

Groceries, travel luggage, or home projects. Add items individually or in batches, cross off items on the fly, and share the live list with your partner on WhatsApp.

Everyday usage patterns:

  • Batch Addition: 'Add whole milk, eggs, ground coffee, and olive oil to groceries'. It parses and tracks each item cleanly.
  • Dynamic Checking: 'Cross off milk and coffee'. Aster marks them done without wiping the history.
  • Live Sync across Phones: You add an item from your desk, and your spouse sees it live when walking through the grocery store.
