📖 AI Writing Polisher: Local Text Optimization Tool
AI‑generated text often suffers from redundancy, mixed colloquial/formal styles, and awkward phrasing. ng.cc's AI Writing Polisher is a fully client‑side, offline‑friendly text optimizer offering three styles: Concise, Formal, and Casual. All processing happens in your browser memory – your articles, emails, and drafts never leave your device, protecting your privacy.
✂️ Concise
Removes redundant adverbs (very, really, extremely), simplifies phrases (in order to → to, due to the fact that → because). Average 15‑20% compression.
🎩 Formal
Expands contractions (can't → cannot, won't → will not, I'm → I am). Perfect for academic writing, business emails, official reports.
💬 Casual
Replaces formal connectors (however → but, furthermore → also, therefore → so). Ideal for blogs, social media, everyday conversation.
🔒 Privacy first
100% frontend, zero network requests. Your business plans, personal diaries, unpublished articles stay local.
🎯 Use Cases
🤖 AI content refinement: ChatGPT, Claude outputs often contain redundant phrases – one‑click concise polish.
📧 Business email polishing: Turn casual expressions into professional language.
📝 Blog style adjustment: Switch between formal tutorials and casual voice for different audiences.
🎓 Academic writing aid: Avoid informal contractions, meet paper guidelines.
Passive → active: it is recommended that → you should, it is suggested that → I suggest
Use contractions: it is → it's, they are → they're
❓ Frequently Asked Questions
❓ Q1: How is this different from Grammarly?
Grammarly is a cloud‑based grammar checker that requires internet and stores your text; this tool is a local rule‑based engine – all rules are hardcoded, zero data upload. Grammarly is more comprehensive; this tool is more private and focused on style conversion.
❓ Q2: Can I customize the rules?
The current version uses a fixed rule set. We plan to add a "custom replacement dictionary" in v2.0, allowing you to add your own rules. Feel free to send us feedback with your common polishing needs.
❓ Q3: Does it support languages other than English?
The rules are based on English keyword substitution, primarily for AI‑generated English text. Chinese polishing requires word segmentation and semantic understanding, which is far more complex. We recommend translating your text to English first, or using this tool as a writing aid for English learners.
❓ Q4: Will my text be leaked?
Absolutely not. This is a static HTML page. You can open Chrome DevTools → Network tab and verify that clicking any polish button makes zero network requests. Your business plans, novel drafts, private emails never touch any server.
❓ Q5: Why didn't some words change after polishing?
This tool uses exact case‑sensitive matching. For example, very will be removed, but Very (capitalized) won't. We suggest converting your text to lowercase first, or manually adjusting. A case‑insensitive option is planned for a future release.
❓ Q6: Can it polish Chinese text?
Currently English only. Chinese text optimization requires semantic understanding, synonym replacement, and sentence restructuring – very different from rule‑based substitution. We recommend using dedicated AI writing assistants for Chinese.
