About TextGrain Remover
TextGrain Remover is an independent project providing a local Unicode character cleaner and practical guides to text watermarking. It is not an OpenAI product, partner or official detector.
Our scope
We separate technical explanations from product availability. Claims about rollout, repositories or access must have an attributable source. Our cleaner reports specific character changes, not AI scores or watermark removal guarantees.
Independent tools and sources
Our guides link to official research and access documentation. Those links are sources, not endorsements or partnerships. The free character cleaner requires no account and does not submit your text to a server or an AI provider.
