An AI writing assistant that lives inside your document.
Nylio's AI writing assistant helps you draft, rewrite, research, and polish — all inside a real document editor. Not a chatbot. Not a sidebar. Built into where you write.
Most AI writing assistants are chatbots that generate text you copy-paste into a document. Nylio is different: the AI lives inside your document editor, so it can draft paragraphs in context, rewrite your existing text, search the web for facts, and check grammar — without you ever leaving the page.

How it works
An AI writing assistant that drafts, rewrites, researches, and checks grammar inside a real document editor with collaboration and export.
In-document AI
Write where the AI can see your context.
Unlike chatbots that generate text in isolation, Nylio's AI reads your document and suggests changes in context. Rewrite a paragraph, expand a bullet point, or draft a new section — the AI understands what comes before and after.
Web research
Research without opening a browser tab.
Ask the AI to find facts, statistics, or background information. It searches the web and returns source-aware answers beside your document, so you can verify and incorporate findings without context-switching.
Advanced models
Choose the AI model that fits your task.
The Pro plan gives you access to GPT-5.4, Sonnet 4.6, and GPT-5.4 Mini. Use the right model for the right task — a faster model for quick drafts, a more capable model for complex research and revision.
Workflow
From first draft to finished document.
Start writing or import a document
Begin with a blank page or import from Google Docs, Word, or Markdown. The AI works with any document.
Let AI help where you need it
Highlight text and ask for a rewrite. Ask AI to draft a section. Run web research for evidence. Check grammar and style in real time.
Export the polished result
When you are done, export to DOCX or PDF, or share with a link for collaboration and feedback.
