About

Memrz

Features
Read full description

Memrz is your intelligent everyday memory companion. Tell Memrz what matters, and bring it back whenever you need it. Where did I keep the property papers? Do we already have this medicine at home? How much money did I give Rahul? Which hotel did Anita recommend in Goa? Life is full of small details like these. They may not matter right now, but days, weeks, or months later, they suddenly do. That’s what Memrz is for. Tell it. Forget it. Just tell Memrz naturally. Memrz helps you capture important details, remind you when needed, and find them again later. WHAT CAN YOU REMEMBER WITH MEMRZ? • Important documents and where you kept them • Medicines and household items you already have • Money you gave, borrowed, or need to follow up on • Warranty cards, bills, receipts, and purchase details • Things family or friends asked you to remember • Important dates, appointments, and reminders • People, places, recommendations, photos, and ideas • Small everyday details you don’t want to lose REAL-LIFE EXAMPLES “The property papers are in the brown drawer of the bedroom cupboard.” Later, ask: “Where are my property papers?” “We already have Crocin 650 in the medicine drawer. One strip is left.” Before buying more: “Do I already have Crocin at home?” “I gave ₹5 lakh to Rahul on 12 August. He said he will return it next year.” Later: “How much money did I give Rahul?” “The washing machine warranty card is in the blue file inside the TV unit drawer.” Later: “Where is the washing machine warranty card?” “Papa asked me to book his train ticket for Diwali. Remind me tomorrow evening.” “Anita recommended Taj Exotica in Goa for our family trip.” Months later: “Which hotel did Anita recommend in Goa?” “I lent my camera to Amit today.” Weeks later: “Who has my camera?” SMART REMINDERS Some memories need to come back at the right time. Just say: “Remind me to submit the GST return on Monday.” “Remind me in six months to ask Rahul about the money.” “Remind me one month before my laptop warranty expires.” Capture it once and let Memrz help you remember later. FIND WHAT YOU SAVED Instead of scrolling through notes, messages, screenshots, or folders, simply ask Memrz naturally. “Where did I keep my PAN card?” “Who has my camera?” “How much did I give Rahul?” “Which medicine do we already have?” “What restaurant did Rohan recommend?” “When does my appliance warranty expire?” Memrz helps bring the right memory back when you need it. REMEMBER DOCUMENTS Remember property papers, PAN card details, insurance papers, agreements, warranty cards, bills, receipts, certificates, vehicle documents, and more. You can also remember exactly where a physical document is kept. REMEMBER WHAT YOU ALREADY HAVE Sometimes forgetting costs money. “We have Crocin 650 in the medicine drawer.” “There is an extra phone charger in the study table.” “There are two unopened toothpaste boxes in the bathroom cabinet.” Before buying again, ask Memrz. REMEMBER MONEY AND COMMITMENTS “I gave ₹5 lakh to Rahul.” “Amit still needs to return ₹12,000.” “I paid ₹25,000 advance to the contractor.” Save the amount with the context and bring it back when you need it. REMEMBER PEOPLE, PLACES AND IDEAS “Rohan prefers window seats when travelling.” “Dr. Mehta asked me to come back after three months.” “We parked the car near Gate 3.” “Idea: create an online store for kids.” Capture things when they happen instead of depending on your memory later. A MORE NATURAL WAY TO REMEMBER Traditional apps ask you to decide whether something is a note, task, reminder, document, photo, person, or place. Real life doesn’t work that way. You simply remember something. Tell Memrz what happened, what matters, or what you want to remember. Memrz helps keep those details ready for when you need them again. Your life, intelligently remembered. Tell it. Forget it.
