Littl

Littl is an AI assistant that doesn't just answer. It gets things done. Say or type what you need in plain language, for example "order milk and curd for tonight", "book a one-way flight to Bengaluru on 5 Oct" or "find me a badminton court in HSR after 7 PM". Littl opens a real browser, searches, compares, fills in the forms and takes it to checkout, while you watch it happen live on your phone. Asks only when it needs you A size, a seat, an OTP, the address to deliver to: Littl asks one clear question in chat and waits. You get a notification, and a reminder if you're busy. You stay in control of payment Littl never pays on its own. At checkout it hands you the payment to approve in your UPI app, and it always tells you plainly whether an order went through. See it before you buy Every product it suggests comes with a link and a photo, so you can tap to check it yourself. Picks up where it left off If a task stops midway, tap "Try again" and Littl carries on from where it got to, not from the start. Remembers what matters Your address, your size, how you like to pay. Littl learns as you go, so you're asked less every time. For You Connect your email and calendar, and Littl surfaces what needs you today, like an urgent email or a meeting to prepare for, as cards you can act on in one tap. Private by design You choose what to connect and can disconnect anytime. Passwords and one-time codes are never stored. Tell Littl what you need. It'll take it from there.
