About the prompt comparison tool
Paste two prompt drafts side by side to see how their length and wording compare. Nothing is sent to a model — this is a plain text comparison, not an AI judgment of quality.
What it measures
Character, word, and line counts for each prompt, plus the difference between them (B minus A).
Word overlap
The similarity score is a Jaccard index: shared lowercased words divided by the total number of unique words across both prompts. It ignores word order and repetition, so two prompts that mean the same thing in different words can still score low — it is a simple, honest overlap metric, not a semantic comparison.
Limits
Each prompt accepts up to 20,000 characters.
Privacy first
The comparison runs locally in your browser. Nothing you paste is sent to a Dockzio server or to any AI provider.
