Sundae AI agent: a personal assistant you just text

Key facts

What did sundae_bar launch?

On 21 October 2026, Sundae Bar AI PLC, the enterprise AI platform company quoted on London’s AIM market, announced the beta launch of Sundae, a personal AI agent for everyday life (London Stock Exchange). It is the company’s first consumer product, and it grew out of technology sundae_bar had already built for business customers.

Chief executive Jill Kenney had introduced Sundae a week earlier in a letter on the company blog, dated 15 October. She wrote that the first 100 beta places “filled almost immediately” and that another 100 had been opened (sundae_bar). By the time of the formal announcement the company counted 150 sign-ups and had started a waitlist, rotating new testers in as places free up (Investegate).

How does Sundae work?

A contact in your phone

Sundae has no app. You save one number, +1 (937) 896-2734, and message it the way you would message a capable friend: a text, a voice note or a photo. It works over iMessage on an iPhone, iPad or Mac, over RCS chat on Android, and through WhatsApp, and messages travel over Wi-Fi or mobile data, so texting it is free wherever you are (sundae.md; Investegate).

A computer of its own

Behind the chat, every person gets their own computer with its own browser, files and memory, kept separate from everyone else’s. When you give Sundae a job it opens that browser, does the work and texts you the result with a screenshot so you can check it. Bigger jobs run in the background, and Sundae texts you once when it is done (sundae.md). Sites you sign in to once in Sundae’s browser stay signed in; connecting email and calendar directly is listed as coming soon.

Memory you control

Sundae remembers your preferences, the people you mention and what you were working on. You can ask what it knows, tell it to forget something, or tell it to stop learning, and disconnecting a service also removes what it learned from that service (sundae.md).

What can you ask Sundae to do?

The examples on sundae.md are refreshingly ordinary. Sundae finds tables and flights at today’s prices and takes your choice to the checkout. Send a photo of a bathroom basin with its measurements and it searches real shops for replacements that fit. Photograph a letter and it tells you what it is, what it costs and what you need to do. It sets reminders, checks a price every morning and texts you when it crosses your line, builds a simple party page with a shareable link, and makes pictures, short videos or music on request. Longer comparisons, such as broadband deals, come back as a spreadsheet (sundae.md).

Kenney says she uses it to track shares, follow her children’s sports schedules, book restaurants, create short podcasts on new topics and find food when she lands in a new city (sundae_bar). These map neatly onto our errand runner and deal hunter templates, the restaurant and appointment booking use case, and skills such as price tracking and restaurant booking.

How does Sundae keep you in control?

Sundae handles small things and tells you afterwards, but it asks first before it spends money, sends anything to someone else, deletes anything or opens an account. For purchases it fills the basket and stops at the checkout: you type your card and press pay yourself. When a site needs a password, card number or code, Sundae sends a private link to its screen so you can type it in directly (sundae_bar).

The company is open about the trade-offs of a beta. Conversations are stored securely and used to run and improve Sundae, with card numbers, codes and passwords left out, and messages go to the AI and messaging services it runs on (sundae.md). Text “stop” to halt a task at any time.

How much does Sundae cost, and who can use it?

Sundae is free to start, with no card needed. There is a daily limit that resets at midnight your time, and Sundae warns you when you are close. A paid plan called Plus raises the limit; its price is not published on the website, and you text “billing” to see it (sundae.md). Places are limited while the beta grows, so no reply means it is full for now.

Regional restrictions have not been announced, and the examples on the site use both pounds and dollars. sundae_bar has not published user numbers beyond the 150 early sign-ups or a date for leaving beta.

Why is an enterprise AI company building a personal agent?

sundae_bar’s main business is a subscription platform where companies use ready-made or custom AI agents. To test thousands of AI skills submitted through its Bittensor subnet SN121, nearly 7,000 so far, the team built a system that gives an agent its own computer, browser and tools, runs a task, scores the result and shuts everything down again. Kenney says that system turned out to be the foundation for Sundae (sundae_bar).

“One technology foundation, two distinct markets,” she said in the announcement, adding that the company’s focus remains its enterprise business while it explores consumer demand (London Stock Exchange). For businesses watching the personal agent wave, it is a neat example of internal agent infrastructure becoming a product of its own.

How does Sundae compare with Tab and LVLZ?

Sundae joins a busy group of text-first personal agents. Tab, which emerged from stealth in early October, is texted on iMessage or WhatsApp and has its own phone number, computer and wallet (TechCrunch). LVLZ pairs a texting agent with a web workspace showing every task, and enforces approvals outside the model (LVLZ). Sundae stands out for its free starting tier, its per-person computer and support for Android users through RCS.
