Frequently Asked Questions
How do I rename a product everywhere?
Enter old and new names, run once: 200 mentions across a 50-page spec swap in seconds. Review the match count first — 200 expected vs 214 found means 14 need a human look.
Case-sensitive or not?
Always case-sensitive with no toggles: Apple never matches apple, and art inside earth always matches since there is no whole-word mode. Run a second pass with different casing when prose needs it.
Can I replace across line breaks?
No — the Find field is single-line, so patterns containing line breaks cannot be entered. Split the job into single-line passes, and keep the original in a second tab until the replaced version reads clean.
Does my edited document leave the browser?
No — replacement runs locally in your browser. Text never leaves your device.
