In a classic scientific-calculator body
The same size, the same keys, the same monochrome screen. The lens is on the back; it shoots only when you press the key in AI mode.
2K camera with autofocus
It finds focus by itself in a couple of seconds. Even the small print of a textbook page is readable, the whole page at once.
Eight AI models
GPT-5.6, Gemini 3.5, DeepSeek and Claude — from cheap and fast to the strongest one. You switch models on the keypad itself, in the MODE menu.
The answer comes back on its own screen
In about 20 seconds, with fractions, roots and powers laid out as in a notebook — not as one line of text.
Its own WiFi
A 2.4 GHz network, remembered by itself; a phone hotspot works too. No phone in your hand, no app to install.
Offline it is a full scientific calculator
50 keys and honest decimal arithmetic: 0.1 + 0.2 = 0.3, with no tail. The AI module is powered off meanwhile, so it does not drain the battery.
How it works
What it costs to use
The first month is free: 300 requests over 30 days, nothing to pay. After that you buy packs of requests, from 1.6 ₸ per question to a basic model. Or plug in your own OpenAI, Gemini, DeepSeek or Anthropic key and pay the provider directly, bypassing us.
Questions
When will it ship?+
It is a pre-order: we make calculators in batches and ship them by CDEK to the pickup point you choose once the batch is ready. The shipping date and delivery time are shown when you order.
Does it need the internet?+
For AI, yes: WiFi 2.4 GHz, a phone hotspot works too, and it remembers the network by itself. As a calculator it works offline, always.
Do I need a phone or an app?+
No. The calculator goes online by itself and the answer arrives on its own screen.
Can I ask without a photo?+
Yes. Type the question on the on-screen keyboard and send it without a shot.
What does it cost to use?+
The first month is free — 300 requests. After that, packs of requests from 1.6 ₸ per question, or your own provider key.
