Poli is a free Chrome extension designed to enhance writing through AI-powered grammar correction and translation features. Users can correct grammar mistakes and translate text seamlessly across various websites and text fields. The tool offers instant corrections with explanations, allowing users to learn from their errors rather than merely fixing them. This functionality supports efficient writing and improved language skills.

In addition to grammar correction, Poli allows translations in over 20 languages, including major languages like English, Spanish, and Chinese. Pro users receive cultural insights and nuanced translation options. The extension saves a history of corrections and translations for easy access and review. With a focus on user privacy, Poli ensures that text data is processed securely without being sold or used for AI training.
