What the tool finds
- Palindromic words: Tokens like madam, refer, level.
- Palindromic substrings: Inner sequences inside words, for example anna in Hannah.
- Palindromic phrases: Sentence-level detection across spaces and punctuation (e.g., never odd or even).
- Exact positions: Start index, end index, and length for each match (handy for QA tickets).
- De-duplication: Optional unique-only listing to reduce noise in large texts.
How to use it
- Open the Palindromic Word Finder.
- Paste or type your text to see live highlights.
- Choose mode: Words, Substrings, or Phrases.
- Set options: Ignore case, Ignore spaces, Ignore punctuation, Ignore diacritics.
- Export results as CSV or JSON, or Copy Report for tickets and docs.
Cleaning messy input first helps. Use Whitespace and Formatting Cleaner and Remove Empty Lines. For columns and lists, try the Text ↔ List Converter; to profile counts and length, use the Word and Character Counter.
- Control noise: Increase Min length to avoid tiny matches.
- Normalize accents: Enable Ignore diacritics so réifier ≈ reifier. For code points and names, see Symbol and Character Info.
- Phrase mode: Turn on Ignore spaces and Ignore punctuation for sentence-level palindromes.
- QA workflow: Use positions to reproduce issues in templates, DB fields, and search pipelines; compare versions with the Code Diff Checker.
Advanced options and internals
- Three modes: Words, substrings, and phrases using an expand-around-center strategy for thorough finds.
- Unicode-aware: Diacritic handling helps with international text and mixed content. For deeper character insights, see Symbol and Character Info or the guide Unicode and ASCII basics.
- Export: One-click CSV/JSON plus a human-readable report for quick share or audits.
Use cases and quick workflows
Linguistics and NLP: Collect palindromic features, then profile terms with the Word and Character Counter and deduplicate lists via the Alphabetizer.
QA and content teams: Detect mirrored strings that can trip validation; fix casing with the Case Converter and remove repeats with the Duplicate Word Finder.
Education and puzzles: Generate examples, format lists with the Text ↔ List Converter, or create placeholder text with the Random Text Generator.
Why palindrome detection matters
Symmetry patterns expose edge cases in search, tokenization, validation, and UI behavior. Handling case, punctuation, and accents correctly keeps content accessible and predictable. Finish with a clarity pass in the Grammar Corrector and standardize headline case with the Case Converter.
