How tersOS shows up.

Paper, ink, one highlighter. Everything you need to put tersOS on a slide, a poster or a post — and have it look like us — is on this page. When in doubt, use less.

tersOS wordmark on paper
on paper — ink letterforms, os. on the yellow block
tersOS wordmark on ink
on ink — paper letterforms, yellow os.
  • The full stop is part of the mark. It's tersOS. — lowercase “ters”, capital “OS”, period. A statement, not an acronym.
  • Always use the SVG files — never retype the wordmark, even in Space Grotesk (its face). The files are in assets.
  • Clear space: keep at least the height of the “OS.” block free on all sides. Minimum width 90 px on screen, 24 mm in print.
  • Never recolor it, add a shadow or glow, or stretch it.
  • Never place the paper version on photography or dark grounds — that's what the ink version is for, and vice versa.
  • On busy photos, put the wordmark on a solid paper or ink band, not directly on the image.

Color

The palette is a printed page: cool near-white paper, blue-black ink, one yellow highlighter. A typical promo is ninety percent paper and ink; yellow touches three or four words. Click a chip to copy its value.

  • Yellow is a highlighter, never a glow. No gradients, no auras, no glassmorphism, no yellow text on white.
  • Warm cream backgrounds are betastudio territory (our parent company). If it looks cozy-beige, it's drifted — pull it back to paper.
  • Dark surfaces appear only two ways: the closing ink band, and product screenshots framed as plates.

Type

fraunces — display & headlines

Coworking got better. Its software didn't. Until now.

Weights 400–600. Italics for emphasis, the marker for the one phrase that matters. Headlines read like magazine covers: short, declarative, sentence case.

inter — body

Body copy is Inter, set generously. It talks about real operations — parcels at the front desk, tabs that close at month-end, ten TVs on two floors — in plain sentences a person would actually say.

jetbrains mono — captions & metadata

fig. 01 — the backoffice · app.tersos.io · captured live

Small, uppercase, letter-spaced. Used for figure captions, section kickers, indexes and timestamps — the texture that makes pages feel printed.

  • All four faces are free on Google Fonts: Fraunces, Inter, JetBrains Mono — and Space Grotesk, which is reserved for the wordmark only.
  • In decks where fonts can't be embedded, fall back honestly: Georgia for headlines, Arial for body, Courier New for captions. Don't substitute a different “fancy” serif.

Voice

WeWork upped the game of coworking. tersOS ups the game of coworking software.
the positioning — every promo is a variation of this
principles
  • Human and concrete. Name real things — rooms, parcels, invoices in KM — not “solutions” or “workflows”.
  • Proof over hype. tershouse is the evidence (“built by people who run a space”), never “the system” itself — tersOS is multi-tenant.
  • Plain verbs, sentence case, no exclamation marks. Confident category-raiser, not a scrappy pitch.
  • Banned words: seamless, empower, leverage, revolutionize, supercharge, all-in-one (say “one system” instead).
sounds like us / doesn't
  • Yes: “Every room, booked without a single Slack message.”
    No: “Seamlessly optimize your space utilization.”
  • Yes: “The 2am booking follows the same rules as the 9am one.”
    No: “AI-powered workspace innovation, 24/7.”
  • Yes: “Ten TVs on two floors, one dashboard.”
    No: “Enterprise-grade digital signage at scale.”
boilerplate — copy as-is

tersOS is the operating system for coworking spaces — bookings, members, billing, events, digital signage and an AI assistant in one system. It's built by the team behind tershouse, a working coworking space in Sarajevo, and it runs that space every day. Learn more at tersos.io.

Imagery

the product appears as plates

Dark product UI never floats on a dark slide. It sits framed on paper — white mat, hairline border, mono caption — like a plate in a printed book. Use the approved screenshots from assets; they're captured from the live system, not mockups.

photography

Real rooms, natural light, people incidental. Every photo gets an honest mono caption — place and time (“tershouse, floor 2 — friday 09:41”). Licensed photos get neutral captions; never label stock as tershouse.

In practice

slides & decks
  • Paper background, ink text. One Fraunces headline per slide with a single yellow-marked phrase.
  • Mono kicker top-left (“01 — bookings”), generous margins, hairlines instead of boxes.
  • At most one dark slide per section — and only to show the product, framed as a plate.
social & promos
  • Same recipe at 1:1 or 4:5. The yellow marker stroke is what makes us recognizable at scroll speed.
  • One idea per tile: a marked headline, or a plate, or a photo with a mono caption — not all three.
  • Wordmark small, bottom-left or bottom-right, always from the SVG.
print
  • Paper may go pure white on press; ink stays #17181C — never 100% black.
  • Yellow prints as a solid spot block behind words, drawn slightly past the text like a real highlighter.
  • Captions in mono, small. If it looks like a magazine spread, it's right.
