Check copied NotebookLM text for hidden characters
Inspect copied NotebookLM text for literal hidden Unicode. Google documents SynthID for NotebookLM audio, while text conclusions require supported provider verification.
Findings will appear below the cleaned text.
Clean My Copy finds literal hidden characters and formatting. It does not determine who or what authored text, detect every provenance method, or claim to remove statistical or model-level watermarks.
What this checker can and cannot tell you
Clean My Copy detects literal, removable characters such as zero-width spaces, direction controls, soft hyphens, and non-breaking spaces. These may appear for many ordinary reasons, including web formatting and copy-and-paste behavior. Their presence is not proof that text was generated by AI.
The cleaner removes those formatting artifacts. It does not paraphrase content, bypass safeguards, validate authorship, or claim to defeat statistical or model-level watermarking.
