FAQ
Is my text uploaded?
No. Everything runs locally in your browser.
How do I prevent URL changes?
Keep “Skip URLs” enabled in Advanced settings.
Can I share settings with my team?
Use “Share settings link” to copy a URL that contains only settings.
Why did auto mode turn off?
Large inputs disable auto mode to keep processing fast. You can still run manually.
