What do cleaner tools do?

Cleaners remove unwanted characters, normalise whitespace, strip PII, and prepare text for downstream processing in AI or data pipelines.

Can I clean data before sending it to an AI model?

Yes. Cleaner tools are designed specifically to preprocess text before feeding it to LLMs, reducing token waste and improving response quality.
