Frequently Asked Questions
What text analysis tools does Texterfly offer?
Texterfly offers 8 free text analysis tools: Word Counter (reading time, readability, keyword density), Grammar Checker, ATS Resume Builder, Advanced Text Anonymizer & PII Redactor (12 PII types, GDPR & HIPAA friendly), Text Extractor, Text Compare, Anagram Solver, and Text Reverser. All are free, browser-based, and require no signup.
What does the Word Counter measure?
The Word Counter measures words, characters (with and without spaces), sentences, paragraphs, and unique words in real time. It also calculates estimated reading time (at 200 WPM), speaking time (at 130 WPM), Flesch-Kincaid readability score, and keyword density for any target term. It shows character limit warnings for Twitter (280), LinkedIn posts (700), and other platforms.
What is PII and which types does the anonymizer detect?
PII (Personally Identifiable Information) is any data that can identify an individual. The Text Anonymizer detects 12 PII types: email addresses, phone numbers, social security numbers (SSN), credit card numbers, dates of birth, street addresses, person names, IP addresses, URLs, IBAN/bank account numbers, passport numbers, and driver's license numbers. It also supports custom regex patterns for domain-specific identifiers.
How many words should a blog post have for SEO?
1,500–2,500 words for general blog posts. 2,000–4,000 for competitive informational queries where ranking in the top 3 is the goal. 300–800 words for news, announcements, or product pages. Quality and topical depth matter more than raw count — but longer content tends to rank better for informational queries. Use the Word Counter to track count as you write.
What does ATS mean and how does the resume builder help?
ATS (Applicant Tracking System) is software employers use to automatically screen and rank resumes before a human sees them. It parses resumes for keywords matching the job description and rejects resumes using complex formatting (tables, columns, graphics). The ATS Resume Builder creates a clean, plain-text resume, analyzes keyword match against the job description, and exports a file guaranteed to be readable by any ATS.
How does the Text Compare tool work?
Paste two text versions into the left and right panels. The tool performs a character-level diff and highlights every change: additions in green, deletions in red, unchanged text in black. You can switch between side-by-side view and unified view — useful for comparing document drafts, reviewing content edits, and checking before/after changes.
What data types can the Text Extractor pull from text?
Email addresses, phone numbers, URLs (http/https), IP addresses, dates (various formats), currency amounts, hashtags, @mentions, and custom regex patterns. All results are deduplicated and can be copied or downloaded as a clean list.
What is an anagram?
An anagram is a word or phrase formed by rearranging all the letters of another word, using each letter exactly once. Examples: "listen" → "silent", "astronomer" → "moon starer", "debit card" → "bad credit". The Anagram Solver finds all valid dictionary words that can be formed from any letters you provide.
Does the text anonymizer help with GDPR compliance?
Yes. GDPR requires that personal data be protected and minimized. Anonymizing text by removing or masking PII before sharing, archiving, or publishing is a practical step toward GDPR compliance. The tool processes everything client-side — no personal information is transmitted to any server — eliminating third-party data transfer obligations.
What grammar errors does the Grammar Checker detect?
Spelling errors, incorrect verb tense, subject-verb disagreement, missing commas, misused apostrophes, double spaces, run-on sentences, and common word confusions (their/there/they're, your/you're, its/it's, affect/effect). Results appear inline with specific correction suggestions.
Are these text analysis tools free?
Yes. All 8 text analysis tools on Texterfly are 100% free with no registration, subscription, or payment required.
Is my text data private?
Yes. All processing runs entirely in your browser. Your text, resumes, and data are never sent to any server or stored anywhere — especially important for the PII Redactor, which is designed for sensitive documents.
