An easier way to
write documents with AI
Chat helps you think.
WriterOS helps you finish the document.
Use WriterOS when you need more than a one-off answer. It helps you turn a brief, rough notes, or a research task into a document you can refine, version, and reuse over time.
Draft from a brief
Start with an idea, notes, bullet points, or a document brief. WriterOS turns them into a structured first draft.
Write with your preferences
Set tone, length, and language, or let WriterOS infer them from the task.
Refine without losing previous work
Prompt changes like "make it shorter" or "sound more formal" and keep every version saved.
Research while you write
Search the web, review sources, and use them to draft reports and other research-backed documents.

Common questions about WriterOS
Everything you need to know about WriterOS.
WriterOS takes your brief — a brain dump, bullet points, or a PDF — and generates a structured, polished draft. You set the tone, language, and target length before generating. If the draft isn't right, you refine it with a follow-up prompt and regenerate. Every version is saved so you can always go back.
WriterOS works well for professional documents across PR & communications (press releases, media pitches, founder bios), policy writing (concept notes, grant proposals, sponsorship letters), academic writing (abstracts, literature reviews, methods sections), legal documents (MOUs), and business writing (proposals, boilerplates).
You can type or paste your brief directly into the text area — bullet points, rough notes, or a full paragraph all work. On paid plans you can also upload a PDF and WriterOS will extract the relevant content from it.
Before generating, you choose a tone (e.g. Formal, Friendly, Executive, Academic), a language variant (UK English or US English), and a target length (Short, Medium, or Long). The generated draft follows these settings.
Type a refinement prompt — "make it shorter", "use a stronger opening", "remove the second paragraph" — and hit regenerate. Your original draft is saved as a version so you can always compare or restore it.
WriterOS generates clean, well-structured drafts from your brief. It does not run a separate grammar or spell-check pass — you can polish the final text in the built-in rich text editor before copying it out.
You can copy the text from the editor at any time. Dedicated export formats (DOCX, PDF) are on the roadmap but are not available yet.
