Frequently Asked Questions
What is a whitelist/blacklist checker?
A whitelist/blacklist checker is a tool that scans text to identify specific words or phrases. Whitelisted words are approved or allowed terms, while blacklisted words are prohibited or flagged terms. This tool helps with content moderation, profanity filtering, and compliance checking.
How do I use the whitelist/blacklist checker?
Enter your text in the input area, then add comma-separated words to either the whitelist or blacklist fields. Click "Check Text" to scan for matches. The tool will highlight matches and show statistics for each word found.
What does "whole word only" mean?
When enabled, the tool only matches complete words. For example, if you blacklist "cat", it won't match "category" or "scatter". Disable this option to find partial matches within words.
Is the search case-sensitive?
By default, the search is case-insensitive, so "Word" and "word" are treated the same. Enable "Case sensitive" if you need exact case matching.
Can I check multiple words at once?
Yes! Enter multiple words separated by commas in either the whitelist or blacklist fields. For example: "apple, orange, banana". The tool will check for all words simultaneously.
Is my text data private?
Absolutely. All processing happens locally in your browser. Your text and word lists never leave your device, ensuring complete privacy and security.
