What is Sundae?
Sundae is an AI personal assistant from UK-based Sundae Bar AI that you use by texting it from your phone over iMessage, RCS or WhatsApp, just like any other contact. Built for everyday errands, it takes texts, voice notes or photos and handles bookings, shopping, comparisons and reminders using its own computer and browser.
What can Sundae do for you?
Give it a job and it opens a browser, does the work and texts back what it found with a screenshot. It can find restaurant tables and flights at live availability, track down products in real shops from a photo and measurements, read a letter or parking ticket and tell you what to do, watch a product or stock every morning and alert you when it drops below your number, build a simple party page with a matching invite, or make pictures, short videos and music. Longer tasks run in the background and come back as a file, such as a spreadsheet of broadband deals.
How does Sundae keep payments and data safe?
Sundae asks before it pays, sends, posts, deletes or opens an account. It fills the basket and stops at checkout so you enter the card yourself, and passwords or codes are typed by you through a private link to its screen. Each user gets a separate computer with its own browser, files and memory. It remembers preferences and key dates, and you can ask it to forget anything or stop learning.
Who is Sundae for?
- Busy people who want to hand off household admin by text.
- Anyone planning trips, dinners or birthdays who wants options fast.
- Users who would rather not install yet another app.
Sundae pros and cons
There is no app and no account to create: you just text the number. On the downside, it is in beta with a waitlist, usage has a daily cap, direct email and calendar connections are still coming, the examples lean towards the UK, and the company warns it can get things wrong.
