EarlyOffice AI

Ask in words, start from a draft.

  • Create with AI

    Say what you need — “a notice for the autumn event” — and it picks a template and writes a draft.

  • Ask EarlyOffice

    Summarise, polish sentences, tidy tables. It shows you the change before applying it.

  • Fill in my details

    Fill name, team and contact fields at once. Kept on this device only and never sent to the AI.

When you use EarlyOffice AI, your request and the document text needed to answer it go through our server to the AI model provider (OpenAI; Google for hard requests — both USA). Our server does not store them. AI answers and edits can be wrong — check them before you use them. Legal templates and samples help you write; they are not legal advice.

The home screen of the web app: new-document cards, the PDF tools box and a line for asking the AI to write a document.
