Purpose Clarice.ai is an AI writing assistant designed specifically for writers of Portuguese (especially Brazilian Portuguese). It is positioned to help users write "clear, powerful, original, and error-free" text, and it is especially aimed at editing, proofreading, and humanizing AI-generated content so that the text sheds its mechanical feel and comes closer to natural human expression. The official emphasis is on "writing in your own voice, without an AI accent," intended to solve the problem of needing extensive manual revision after using tools such as ChatGPT.
Main capabilities
- Text proofreading and improvement: Provides suggestions across four dimensions: clarity, concision, power, and originality. The official description includes: flagging long and difficult sentences; showing unnecessary words; highlighting adverbs, gerunds, and other elements that weaken expressiveness; and pointing out clichés, stock phrases, and redundancy.
- Grammar and style suggestions: Provides correction suggestions at the grammar and style levels. The company says it has corrected more than 150 million errors.
- Humanization: Transforms text with obvious artificial traces and stiffness into fluent, natural writing, while also being able to rewrite it into different voices and styles.
- Smart rewriting: Can rewrite passages into different tones, purposes, and audience orientations—clearer, shorter, more persuasive, or more natural.
- Creative control: Supports one-click simplification, expansion, paraphrasing, or tone adjustment, allowing users to maintain control over every part of the text.
- Smart paraphrasing: Adjusts rhythm, tone, and clarity while preserving the original meaning.
