AI gives you answers.
Rewriting makes them yours.

Paste, compare, rewrite — in a Markdown workspace
that sits right beside your browser.
Not a place to store. A place to digest.

Philosophy

  • Less tool. More space.

    No plugins, no widgets.
    Just a blank page and your thoughts.

  • Not storage. Digestion.

    Copy-pasting doesn't make it yours.
    Rewriting does.

  • Your words. Your rhythm.

    Side panel or new tab.
    Focus mode when you need focus.

Workflow

Entry → Edit → Clear → Exit

Information flows through, not piles up.

  • Entry

    Write in Markdown.
    Or right-click to convert any page or AI chat.

  • Edit

    In your own words.
    Make it yours.

  • Clear

    Archive to keep. ☆ to bulk export.
    Template to reuse. Trash the rest.

  • Exit

    PDF, DOCX, HTML, EPUB, LaTeX, or .md.
    Export and clear your desk.
