Text Toolkit
Count words, trim whitespace, sort or dedupe lines, find and replace, and more—entirely in your browser.
Overview
Text Toolkit groups everyday writing and editing helpers: word counts and reading time, whitespace cleanup, line sorting and deduplication, find-and-replace, and extractors. Each tool stays on-device so drafts and notes never need to leave your browser for these tasks.

Frequently asked questions
- Which text tool should I open first?
- Start with Word Counter for length checks, Whitespace Trimmer or Remove Empty Lines for cleanup, and Find and Replace for bulk edits. Use Diff Checker when comparing two versions.
- Is my draft uploaded when I use Text Toolkit?
- No. These tools process text in your browser. Optional on-device history only stores recent inputs if you enable it.
- Can I sort and dedupe lines in one pass?
- Use Line Sorter and Line Deduper as separate steps, or combine cleanup tools in sequence. Each page focuses on one clear job for predictable results.
- Does Find and Replace support patterns?
- Yes—open Find and Replace for bulk edits with optional regex and case-insensitive modes. Invalid patterns surface an error instead of silently failing.
- How does reading time get estimated?
- Reading Time Calculator divides word count by a configurable words-per-minute rate (default 200) so you can tune estimates for your audience.
