Console Calculator

CalcuBot goes noticeably further than a typical Telegram calculator. In a private chat you type an expression directly — 4-(cos(3)+2)/3 is a real example from its own listing — and it evaluates full Python-3-style syntax, with access to the math, random, datetime, json and re modules. That means it can do trigonometry, generate random numbers, work with dates, or even parse simple JSON, not just add and subtract.

In group chats the same power is available behind the /cl command, so a calculation doesn't get lost among unrelated messages or accidentally trigger for people who didn't ask for it. With over 18,000 monthly users, it is one of the more established bots in this category, suggesting it has kept working reliably for a meaningful stretch of time rather than being an abandoned side project.

The trade-off is approachability. Python-flavored syntax is a genuine advantage if you already think in those terms, but it is less immediately obvious to someone who just wants a quick sum — there is no visible onboarding message walking new users through what the bot can do, so a bit of trial and error (or checking its listing on a bot directory) helps before you rely on it for anything beyond plain arithmetic.
