Tools
Small, focused tools that do one job. All free, all in the browser, none of them ask you to sign up.
Karnaugh Map Solver
Click cells to set them to 1 and the map groups them for you, showing the simplified expression as you go. No signup, no install.
Open tool →Binary, Decimal and Hex Converter
Flip any bit and watch binary, decimal and hexadecimal move together. Built to show you why the conversion works, not just to hand you an answer.
Open tool →Two's Complement Calculator
See the same bits read as unsigned and as two's complement side by side, and watch what negation actually does to them.
Open tool →Truth Table Generator
Pick a gate and step through every input combination. Useful when you need to check a row rather than trust your memory of it.
Open tool →Graph Algorithm Visualizer
Play, pause and scrub through a traversal. The queue, stack and distance table update alongside the graph, so you can see why the algorithm does what it does.
