A private writing workspace for Mac
Write clearly.
Keep every file yours.
Ampersand is a native editor for Markdown and plain-text files. Open the folders you already use, edit Markdown in rich or source views, and use a local AI assistant without sending your writing to a hosted AI provider.
The shape of
the silence
The house remembered her differently. In the mornings, the floorboards kept quiet. By dusk, they whispered every step back to her.
She set the letter beside the cold cup of tea and read the first line again.
Private by design
Your writing
stays on your Mac.
Ampersand’s writing assistant runs entirely on your Mac, alongside your files. Your documents, prompts, and source material are never sent to a hosted AI provider.
Markdown without the markup
Write normally.
Keep clean Markdown.
Edit headings, lists, quotes, links, and other Markdown as formatted text. Ampersand saves clean Markdown behind the editor, and you can switch to source or synchronized split view at any time.
- Rich editor, Markdown source, and split views
- Focused support for UTF-8 plain-text files
- Adjustable type and light, dark, or system themes

CONTEXT
Use only the context you choose
Choose what the
assistant can use.
Add research, requirements, style guides, notes, or complete files to a session. Ampersand uses that material to guide its suggestions without treating your whole workspace as AI context.
