Frequently asked questions
Everything you need to know about Memosyne.
How does Memosyne work?
Memosyne is an AI assistant that lives in WhatsApp. You message it naturally — text, a voice note, or a forwarded photo or file — like texting a friend, and it schedules tasks, manages lists, recalls what you told it, and nudges you and your people on time. No app download required.
Is my data private and secure?
Absolutely. Your data is encrypted both in transit and at rest. We never sell your data to third parties. You can delete your data at any time.
Do I need to install an app?
No! Memosyne works entirely through WhatsApp. If you have WhatsApp on any device, you can use Memosyne immediately.
What's the difference between plans?
Every plan has unlimited lists, unlimited friends, unlimited reminders a day, and unlimited memory recall. What changes is how much you chat with Memosyne each month — 20 messages on Free Forever, 100 on Spark, 500 on Flow, unlimited on Superbrain — plus recurring reminders, the daily briefing, and priority support on the paid plans.
Can friends really send me reminders?
Yes! With Friend Reminders, you can invite a trusted person to send you reminders. They need to be approved by you first, and you can revoke access anytime.
How do I add a friend?
Share their contact card in the chat, exactly like forwarding a contact to anyone else. Memosyne reads the name and number, shows you the invite before a thing is sent, and your friend only has to reply yes. Prefer typing? Send the number instead — that still works.
Can I send voice notes, photos and files?
Yes. Say it in a voice note and Memosyne acts on what you said. Forward a receipt, a boarding pass, a PDF or a screenshot and it reads the details that matter — the total, the flight time, the date on the letter.
What if I want to cancel?
You can cancel anytime, no questions asked. We also offer a 30-day money-back guarantee if you're not satisfied.
