Frequently Asked Questions
Everything you need to know about the Truth Table Generator.
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.
