The logo, the colours
and how to write esfis.

If you need to talk about esfis in an article, a deck or an integration, take the files from here instead of grabbing a screenshot.

How to use it

Do

  • Use the black symbol on light backgrounds and the white one on dark backgrounds.
  • Leave clear space around it of at least the width of the symbol.
  • Minimum symbol size: 16 px tall.
  • Always scale it proportionally.

Don't

  • Don't recolour it, or add gradients, shadows or outlines.
  • Don't stretch, skew or rotate it.
  • Don't place it over an image without enough contrast.
  • Don't change the typeface of the name or the spacing of the logo.

How it is written

esfis, always in lower case, including at the start of a sentence and in headings. Not Esfis, not ESFIS, not esFis.

It is pronounced ess-feess. If a sentence reads badly starting in lower case, it is better to turn it around: “The esfis app…” rather than “Esfis is…”.

A short description, in case you need one:

esfis is a macOS app that turns your folders into projects, opens the AI agents you already use inside them and keeps one shared context across all of them.

Colours

Clay is the only brand colour: it marks what is interactive and nothing else. The rest is paper and ink.
