Frequently asked questions
Is my text uploaded?
No. Processing happens locally in your browser and the page does not send your text to a server.
Can this tool work offline?
Yes. After the page is loaded or saved with the site assets, the text operation itself does not require an API.
Is there a text limit?
There is no fixed account limit. Very large text may depend on your browser and device memory.
