Key points
- Check each tool's privacy policy for data retention and training-use terms before pasting sensitive text.
- Some tools explicitly state they do not use submitted text to train models; others are vaguer — read carefully.
- For confidential material, consider tools with enterprise data-handling agreements or avoid third-party tools entirely.
Pasting text into a third-party web tool means that text leaves your control, which matters for sensitive, proprietary, or unpublished academic work.
