Frequently asked questions

Is Text Diff free to use?

Yes. Everyday use is free. A free account also saves your history, while watermark-free exports and higher AI limits come with a paid plan.

Do I need to create an account to use Text Diff?

No. You can use it as a guest. Signing in adds saved history, and paid plans add higher AI limits and clean, watermark-free exports.

Is my data kept private?

Text and image tools that can run in your browser do exactly that, so the content never leaves your device. AI tools send your prompt or file to the model provider only to produce the result.

Does Text Diff work on mobile?

Yes. The layout adapts to phones and tablets, so you can use it on the go without horizontal scrolling.
