Overview

Tell your browser what to do in plain language. Casper does it, fast.

Casper is a little detective who lives in your browser's side panel. Tell him what you want — typed or spoken — and he does it in your tabs while you watch. • Find things: "find the cheapest one-way flight to Penang next Friday", "which of these laptops has the best reviews?" • Fill things in: forms, bookings, sign-ups — he asks you for anything he doesn't know. • Read and tell you: "read the reviews on this page and tell me if it's worth buying". • Talk to him: speak your instruction in English, Malay or mixed; he listens and gets on with it. • He remembers you: tell him "remember that I book flights on AirAsia" and he'll use it next time. Everything he remembers is on the Notebook tab, where you can edit, export or delete it. Setting up takes a few minutes and Casper does it with you: he opens the right pages, points at the buttons, and picks up your new keys himself. You bring your own AI key (a free Google Gemini key works), so there's no subscription and no Casper account. You stay in charge: • He works in your own browser, where you can see every click, and you can stop him at any moment. • He asks before anything that spends money or can't be undone, unless you told him to do exactly that. • He never types card numbers, PINs or one-time codes. • Your keys, chats and notebook are stored only in your browser. Page content goes only to the AI provider you chose, to decide the next step. Casper asks once, during setup, for access to the websites you use him on — acting on pages is the whole job. You can take it back any time in Chrome's extension settings. Privacy policy: https://drive.google.com/drive/folders/1ibpSny7Z3E1cCQ7frsQPaF-b9L1fkCRx
