Forget a payment, pay a late fee. Forget a follow-up, lose a client. Forget a friend's birthday, and they notice. Memorae is a memory you can talk to. Tell it once, by text or voice. It reminds you, and anyone else, at the right time, and gives back anything you saved when you ask. JUST SAY IT "Pay rent on the 1st. Call the dentist tomorrow at 10. Send Ana the quote by Friday." One message. Three reminders. Done. YOUR DAY, AT A GLANCE Today and this week: reminders, tasks and calendar, in one place. REMIND OTHERS "Remind Leo on Saturday at 10 to bring the cake." Leo gets it from you. You stop chasing. ASK FOR WHAT YOU SAVED Send Memorae a link, a ticket or a PDF. Later, just ask: "Where's my flight confirmation?" AUTOPILOT: WHEN THIS HAPPENS, DO THAT Set a trigger once. Memorae watches and acts for you. "When Joe emails, tell me right away." "When an invoice arrives, add a task to pay it." "When a client books or cancels, let me know." CONNECT 1,000+ APPS Gmail, Google Drive, Notion, Trello and the other tools you already use. Then don't open them. Just ask: "Add 'send quote' to Trello for Friday." ALL YOUR CALENDARS Google, Outlook or iCloud. Together, finally. Included in every plan. WHEREVER YOU ARE In the app, on WhatsApp or Telegram, or by forwarding emails to memorae@memorae.ai. PLANS Start with a 14-day free trial. After that, Memorae needs a subscription: Origin, Supernova or Big Bang, monthly or yearly. Autopilot and app connections come with Supernova and Big Bang.

Verdict
The clearest difference is in-app purchases: Tethys Visio at none against Memorae's 11. Memorae's advantage is update cadence (every 2 weeks vs monthly). On price, ads, device support and iOS requirement there is nothing between them.
