01 · Uno Serif

A hook where a ball used to be.

Hooked terminals, wedge serifs and a text cut that holds at 16px. Two axes: weight 400 to 900 and optical size 16 to 72, so headlines get sharper and paragraphs get sturdier on their own.

Connect each app once.
Decide what every agent may do.

One sits between an agent and the apps it acts on. You connect each app once, in your own One account, and decide what each agent may do. Agents get a grant, never a credential. A call outside the grant gets a 403 and never reaches the provider. Every action is on the record, and revocation is one click.

Connecting stays free. Revenue comes from enterprise plans, hosted agents, and higher rate limits. The product never handles a credential: a button, two backend routes, OAuth 2.1 with PKCE.

02 · Uno Grotesk

Plain on purpose.

The memory of Akzidenz with a straight-stemmed a, a flat-topped t, a spurless G and terminals cut against the stroke. For interfaces, body copy and everything that should get out of the way.

03 · Uno Mono

Same voice, fixed width.

The grotesk's a, c and s moves at a fixed width, with a slashed zero and box drawing. For code, connection ids and anything that has to line up.

const grant = await one.connect({ app: "gmail", scopes: ["mail.send"] });
if (!grant.allows("mail.send")) return res.status(403).end();  // never reaches Gmail
await one.actions.execute("gmail", "messages.send", grant, { to, subject, body });

Process

How we built it.

Uno starts from open-source typefaces and changes them in code. Every letterform edit is a short script applied the same way to every weight and to the italics, so the family stays one system.

  1. 01 Choose open-source skeletons

    Instead of drawing a thousand glyphs from zero, we started from typefaces released under the SIL Open Font License, which allows modifying and renaming. Four serif and four sans candidates were set in One's real copy and compared side by side. Newsreader won the serif: text-ready, a full weight range and an optical size axis. Schibsted Grotesk won the sans: the closest Akzidenz bones. Roboto Mono came later for the mono.

  2. 02 Build from the real sources

    We pulled each skeleton's original design files (UFO and Glyphs sources) from its public repository, not the compiled fonts. A build script resets them to pristine every run, applies our edits, and compiles variable fonts with fontmake. Nothing is hand-patched, so any change can be undone or redone in seconds.

  3. 03 Redraw the letters that carry the voice

    People recognise a typeface by a few dozen glyphs, so that is where the work went. Each edit moves specific outline points to positions defined as fractions of that glyph's own shape, identically in every master, so the weight and size axes still interpolate cleanly.

    • Serif. Teardrop terminals on a, c, f, r, y, J, 3, 5 and the g ear became hooks. 302 slab-serif ends per master were tapered into wedges. R got a straight leg, Q a shorter tail.
    • Grotesk. a lost its foot spur, t got a flat top, c, e and s got terminals cut against the stroke, G lost its spur.
    • Mono. The same a, c and s moves, so code reads as part of the same family.
    Serif hooked terminals at large size

  4. 04 Proof, look, fix, repeat

    Every change was rendered to an image in a real browser and judged by eye: before against after, huge glyphs at 420px, spacing strings like "ra re ro ry", and the website hero. Two rounds of notes went in (a fuller belly on the a, a rounder r, a cleaner R foot in Black). A coverage audit confirmed Latin, Latin-1 and nearly all of Latin Extended-A.

  5. 05 Italics

    Each skeleton ships its own italic. A transfer script takes every upright edit as a movement, skews it by the italic angle and applies it wherever the italic glyph has the same structure: the serif's capitals, wedges, J, R and Q, and the grotesk's G, c, e, s and t. The rest keep their true italic forms, like the cursive serif lowercase and the single-storey grotesk a.

  6. 06 Ship for the web

    One variable woff2 per family and style, subset to Latin. The art on this page was generated with Higgsfield in the same botanical system as One's ad creative, with a light twin for each image. This page is the review copy; nothing changes on withone.ai or Clockwork until the design is approved.
