Cognitive Distortion Spotter
Paste an anxious thought into the box. The tool scans it for twelve common thinking traps, highlights the matched words, and explains what each one is doing.
A single sentence is enough. Or a worry that's been looping for an hour. Verbatim, not "polite".
One thought at a time
Type the specific sentence that is bothering you, not a general mood. The tool works on language, not feelings.
When you can name it
Useful when a thought is loud but you're not in crisis. If intensity is very high, try Box Breathing first.
A nudge, not a verdict
Three or more matches is typical. Zero doesn't mean the thought is accurate — just that the language didn't trip the patterns.
What this actually does
The "12 cognitive distortions" come from a 1980 CBT workbook by David Burns. They're recurring patterns of language that tend to make anxious or depressive thoughts feel more certain than they are. Naming the pattern — saying "that's catastrophising" — usually loosens its grip a little. That's the whole mechanism.
This tool is a keyword pattern-matcher, not a mind-reader. It looks for the small, repeated words that accompany each trap ("always", "should", "what if"). It catches a lot, but it misses sarcasm, jokes, and thoughts expressed in unusually neutral language. Use what it flags; ignore what it doesn't.
Who it's for
People whose anxiety shows up mostly in words: the internal monologue, the imagined dialogue, the email you haven't sent yet. People who already know that their thoughts aren't facts but want a faster way to see which thought is which.
It is less useful when anxiety is purely physical — a racing heart with no attached sentence — or when you're too activated to read. In those moments, do Box Breathing or 5-4-3-2-1 first.
How to read the results
The order of matches is roughly the order you might want to look at them. The first match is usually the most powerful distortion in that sentence. Read its explanation slowly — the question at the end is the one worth sitting with.
If the tool flags "Catastrophising" and "Mind-reading" together, that's a common pairing: assuming the worst, then assuming others already see it. If it flags only "Should statements", the thought might not be unrealistic, just over-prescriptive.
Limitations
The list is English-language and idiomatic. Translated or non-native English can produce false negatives. The tool will not catch a thought that's just an image, a sensation, or a feeling — by definition, those are not sentences. It's also bad at picking up cultural scripts ("I should be grateful", "good daughters don't…") that don't use the trigger words. If a thought feels important but nothing matches, try the Thought Record instead.
FAQ
Does it send my text anywhere?
No. The matching happens entirely in your browser. The text never leaves the page.
What if zero patterns match?
That usually means your sentence was neutral or contained idioms the matcher doesn't know. Try rephrasing in plain words ("she thinks I'm bad at my job") rather than abstract ones ("I'm underperforming").
Why 12 and not more?
Twelve covers most everyday anxious thoughts. A longer list becomes harder to read and gives the impression of a diagnosis. If a thought doesn't fit any of these, it might be a value question, not a distortion question — see the Thought Record.
Is this an AI?
No. It's a fixed list of pattern matches. It does not learn, it does not generalise, and it will not understand what you meant. Treat its output as one input to your own judgement, not a conclusion.
What are the common mistakes when using Cognitive Distortion Spotter?
Most common mistakes come down to four habits: entering 20 when the field expects 0.2 because the field is a percentage; leaving a field blank and accepting the default without checking what it stands for; changing one input and reading a result that was calculated before the change; and quoting the output as an exact figure when the page describes it as a reference estimate. Press calculate again after any edit, and treat the number as a reference point rather than a final answer.Advertisement
