About This Tool

uPet is an AI virtual-pet companion that also works as a productivity assistant, living right inside your browser. Adopt a pixel pet with its own personality — cat, dog, rabbit, hamster, fox, parrot, penguin, or panda — and chat with it using 14 leading models (GPT, Claude, Gemini, DeepSeek, and more); it remembers your interests and what matters to you. At the same time, uPet is a sidebar assistant: ask about the current page, explain selected text, translate, polish writing, and draft emails. Daily check-ins, a mood journal, mini-games, a focus timer, and a growth system (baby → teen → adult → elder) weave companionship and productivity together. Pet data is stored locally by default, accounts are optional, and data is never sold.

Background

uPet is a browser-extension AI virtual-pet companion by the upet.cc team, first published on the Chrome Web Store in May 2026 and also listed on the Edge Add-ons store, positioned as 'a little company plus a little productivity.'

Technology

Built on Manifest V3, the pet chat connects to 14 third-party models (GPT-5.4, Claude Sonnet 4.6, Gemini Flash, DeepSeek V3, and more). Pet data is stored locally in the browser by default, accounts are optional, and payments run through Stripe.

Market

Global browser users across 20 languages, monetized via a free tier plus Lite/Pro/Premium subscriptions, with a privacy-first, local-storage stance.

Best For

People who want an always-there pet that can also chatUsers who want AI to read pages, translate, and polish emailsThose building small habits via check-ins and a mood journalPrivacy-minded users who prefer local data storage

Editorial Note

uPet blends a charming, memory-capable pet with a genuinely useful sidebar assistant, but it's fundamentally a browser extension leaning on external models, with a still-small ecosystem — fine as a toy-plus-tool, not a heavy productivity suite.
