TipiCalc Calculator

TipiCalc Calculator is a lightweight, keyboard-first calculator you can open instantly from your browser toolbar or with a hotkey. Just start typing your expression and press Enter — no mouse needed. It supports smart parsing, mathematical functions, and handy shortcuts for working with the last result, so you can do multi-step calculations quickly and comfortably. It captures even the smallest nuances, making it convenient and familiar in everyday use. Inspired by Cloudy Calculator. HIGHLIGHTS - Instant pop-up calculator: open from the toolbar or with a shortcut (default: Alt+T) - Type and press Enter - Works offline - Friendly to both dot and comma decimals (outside function calls) - Time arithmetic: use `t` prefix (e.g., `t 1:20 + 30`) or time literals (e.g., `1h 30m + 15m`) - Plotting: visualize functions, parametric and polar equations - Power features for power users: last result placeholder and auto-prepend WHAT YOU CAN TYPE - Operators: +, −, ×, ÷, integer division (// or \), remainder (%), exponent (** or ^) - Parentheses and whitespace anywhere - Constants: pi, e - Functions: sqrt, root, ln/log, lg/log10, log(x, base), sin/cos/tan, asin/acos/atan, rad2deg, deg2rad, max, min, sum, mul, avg, floor, ceil, round, trunc/int, frac, abs, random/rand/rnd, gcd, lcm, is_prime SMART CONVENIENCES - Use @ to insert the last successful result anywhere: @ * 2, max(@, 10) - Start with a binary operator and TipiCalc will auto-use the last result: typing + 5 becomes <last> + 5 - Both 3.14 and 1,5 work outside function calls; inside functions, use dots for decimals EXAMPLES - sin x * cos x — parentheses are optional for single-arg functions - 1h 20m + 40m → 2:00 - gcd(12, 18) → 6 - is_prime(17) → 1 - sqrt(9) → 3 - root(3, 8) → 2 - ln(e) → 1 - lg(1000) → 3 - log(8, 2) → 3 - sin(pi/2) → 1 - 7 // 3 → 2 - frac(3.14) → 0.14 - @ * 2 — doubles the previous result KEYBOARD AND USAGE - Open TipiCalc: click the extension icon or press Alt+T (you can change the shortcut in your browser’s extension shortcuts) - Press Enter to evaluate, Esc to close the popup PRIVACY - No ads, no tracking, no analytics - Requires only minimal permission to store your settings (extension storage) - Works fully offline WHY TipiCalc? - Faster than reaching for your phone or OS calculator - Built for people who think in expressions, not buttons - Compact, reliable, and focused on what matters: getting the right number, right now TipiCalc Calculator — type, press Enter, done.
