Neutral
A clean, objective voice that works almost anywhere. ZeroQuill AI avoids slang and heavy formality while keeping sentences straightforward and concise—perfect for general documentation and internal updates.
Academic
Precise terminology, formal register, and disciplined structure. The editor favors cautious claims, coherent citation framing, and measured transitions that preserve scholarly credibility in essays, theses, and manuscripts.
Business
Professional and succinct, with concrete verbs and action-oriented phrasing. It reduces fluff, clarifies outcomes, and maintains a confident but respectful voice for stakeholders, clients, and leadership.
Formal
Elevated diction and careful sentence architecture for official correspondence, policies, recommendations, and public statements. The tone is courteous, polished, and consistent.
Friendly
Approachable and warm without being casual to the point of imprecision. Ideal for user communications, help content, community posts, and brand messaging that needs to feel human.
Casual
Conversational, light, and direct while still grammatically sound. Good for social posts, team chats, and informal announcements where personality helps ideas land.
What the editor should prioritize ?
Correctness
Precision on Every Line
Prioritize error-free text. This focus concentrates on grammar, spelling, punctuation, and mechanics: subject–verb and pronoun–antecedent agreement, consistent tense and voice, correct article and preposition use, serial commas and quotation punctuation, and consistent number/date formats. Choose Correctness when accuracy and professionalism are paramount—technical documents, formal emails, resumes, and manuscripts.
Clarity
Clarity That Cuts Through
Make your message unmistakable. Clarity reduces ambiguity, simplifies needlessly complex phrasing, splits overloaded sentences, and removes filler that obscures key ideas. It also encourages consistent terminology and helps paragraphs hold a single, obvious topic. Choose Clarity when readers need to grasp your point quickly—instructions, reports, presentations, and academic sections that synthesize sources.
Engagement
Engage Without Fluff
Keep readers interested without sacrificing precision. Engagement varies rhythm and sentence openings, selects stronger verbs, trims monotone hedging, and strengthens openings and conclusions so each section invites the next. It works especially well with Friendly, Business, or Casual tones. Choose Engagement for articles, landing pages, newsletters, and executive summaries where attention matters.
