FAQ
- Q: Can I publish AI-written articles directly?
- A: Better not to. AI is good for drafts and structure, but before publishing, review facts and add your own views and examples. A good rule: AI does 80%, you polish 20%.
- Q: Will AI writing get detected?
- A: Major platforms can detect AI content now. Use AI to assist rather than replace—add your own experience, data, and opinions to make it feel human.
- Q: Are free AI writing tools enough?
- A: For everyday use, yes. DeepSeek is fully free and high quality, and ChatGPT's free tier covers most needs. For heavy professional use, Jasper AI and Notion AI's paid tiers are nicer.
