Writing, with room to think
A quiet place
for big ideas.
Ampersand is a native Mac workspace for serious writing—stories, edits, technical specs, documentation, research, and more—with an AI partner that runs privately on your Mac.
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.
The promise
Your documents
stay yours.
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.
The writing room
Fewer controls.
More control.
Draft a chapter, edit a report, or shape a technical spec on a calm, true WYSIWYG canvas while Ampersand keeps clean Markdown behind the scenes. Switch to source or synchronized split view whenever you want to see the structure.
- Rich editor, Markdown source, and split views
- Focused support for UTF-8 plain-text files
- Adjustable type and light, dark, or system themes
The shape of the silence
