✅Truth Table Generator
Type a boolean expression and get the complete truth table instantly.
Operators: AND, OR, NOT, XOR, NAND, NOR, -> (implication). Use parentheses to group. Variables are single letters (A–E, up to 5).

Free Truth Table Generator
Verifying a boolean expression by hand row by row is slow and error-prone. Our free truth table generator does it instantly — type any boolean expression using AND, OR, NOT, XOR, NAND, NOR, or implication, and get the complete truth table for every possible input combination.
Invalid syntax like mismatched parentheses is flagged clearly instead of producing a silently wrong table, and TRUE rows are highlighted for quick scanning.
Useful for digital logic coursework, discrete mathematics, and verifying circuit logic before building it. Copy the finished table as plain text for your notes or assignment. No sign-up, no downloads, no limits. See the About page or the FAQ for more.

Frequently Asked Questions
What operators are supported?
AND, OR, NOT, XOR, NAND, NOR, and implication, with parentheses for grouping.
How many variables can I use?
Up to 4–5 variables; beyond that the table becomes impractically large and is capped with a message.
Is it free?
Completely free, no sign-up or limits.
Does it show intermediate steps?
The final result column is always shown, evaluated from your full expression.
What if I type an invalid expression?
A clear error message is shown for issues like unmatched parentheses or unknown variables — never a wrong table.
What notation should I use?
AND, OR, NOT, XOR, NAND, NOR, and -> for implication, with single-letter variables A–E.
Can I copy the table?
Yes, a one-click copy produces a plain-text version of the table.
Are TRUE rows highlighted?
Yes, for quick visual scanning of when the expression evaluates true.
Is my data stored?
No; everything runs in your browser.
Does it work on mobile?
Yes, the table is responsive and scrolls horizontally if needed rather than overflowing the page.
