Generate truth tables from logical expressions with AND, OR, NOT, XOR, NAND, NOR.
AND, OR, XOR, NOT, NAND, NOR — up to 4 variables
| A | B | A AND B |
|---|---|---|
| 0 | 0 | FALSE |
| 0 | 1 | FALSE |
| 1 | 0 | FALSE |
| 1 | 1 | TRUE |
AND / && / &
True when both inputs are true
OR / || / |
True when at least one input is true
NOT / !
Flips the truth value
XOR / ^
True when inputs differ
NAND
NOT of AND — false only when both are true
NOR
NOT of OR — true only when both are false
The Truth Table Generator on AiTechWorlds generates complete truth tables for any boolean expression or logical formula. Truth tables are fundamental to digital logic design, computer science education, propositional logic, and software testing. They enumerate all possible input combinations and show the output for each, which is essential for verifying that a boolean expression behaves as intended. Enter any expression using variables (A, B, C) and operators (AND, OR, NOT, XOR, NAND, NOR, IMPLIES), and the tool automatically generates all 2^n input rows with computed outputs. It supports both symbolic notation (&&, ||, !, ^) and English keywords (AND, OR, NOT, XOR). All generation runs in your browser. AiTechWorlds built this for CS students, logic design students, and developers testing conditional expressions.
Enter an expression
Type your boolean expression — e.g., (A AND B) OR (NOT C) or (A && B) || !C.
View the truth table
The complete truth table with all input combinations and the output column appears automatically.
Add more variables
Use additional variable names (up to 5) for more complex expressions.
Check sub-expressions
Toggle to show intermediate sub-expression columns for debugging complex formulas.
Copy or export
Copy the table as text, CSV, or formatted HTML.
