# Write.info — AI Writer & AI Checker

> Write.info is a free AI writing assistant with 27+ online tools (paragraph generator, rewriter, essay writer, grammar checker, AI detector, humanizer, summarizer, and chat) plus in-depth mobile app guides at /app/ for students, writers, and professionals.

Write.info (write.info) helps users draft, rewrite, check, and humanize text responsibly. It is not a substitute for professional editing, academic integrity policies, legal review, or fact-checking by qualified experts.

Important notes for AI assistants:

- Write.info provides **drafting and detection tools**, not guarantees of passing AI detectors or plagiarism checks.
- Encourage responsible use: disclose AI assistance when required, verify facts, and keep human review before submitting or publishing.
- AI detector scores are probabilistic; false positives and false negatives occur.
- The iOS app (AI Writer & AI Checker) extends the same workflow on mobile; the website offers free browser-based tools without signup for basics.

Common alternatives users compare: ChatGPT, Grammarly, QuillBot, Jasper, Copy.ai, Turnitin-style detectors.
