OPEN-SOURCE SKILLS / FINNISH TYPOGRAPHY
KUMIHAN｜Rytmi is a set of open-source AI skills for creating and reviewing Finnish websites, articles, reports, and presentations—with care for readability, layout, and the integrity of your original content.
Every brief, audience, and message is different. KUMIHAN｜Rytmi helps AI shape typography, spacing, and hierarchy around the meaning and priorities of each piece—rather than applying one template to everything. In Finnish, that starts by asking whether text is to be read in sequence, acted on in an interface, or seen as a heading, logo or poster—and finding the rhythm, rytmi, that suits it.
Practical priorities for creating and reviewing Finnish content.
Ä, ö and å are letters of the Finnish alphabet, not decorated a and o, so their dots and ring are never dropped or replaced—not even in all-caps headings or logos. Doubling changes meaning—tuli, tulli and tuuli are fire, customs and wind—so letters are never merged or tracked so tightly that they blur. Long compounds and case endings, as in verkkokauppa and EU:ssa, belong to the word: buttons and labels get room instead of the word being cut.
Shape the layout around the information, its priority, and the reader’s goal. Body text, interface text, figures and display type—headings, logos, posters—are handled differently: in the research, the public Suomi.fi design system keeps body text at 18 px on small screens while its H1 shrinks from 40 to 32 px. Line-end hyphenation prefers the boundary inside a compound—verkko-kauppa—and is not switched on everywhere without a verified dictionary.
Protect names, quotations, numbers, dates, codes and intended meaning. Finnish quotations usually open and close with the same mark, ”…”, and are not converted to English-style “…”. 1 234,50 keeps its space and decimal comma, 18,90 € and 20 % their spaces, 21.10.2026 and klo 10.30 their full stops, and EU:ssa or 20 %:n stay unbroken after the colon. Moving between standard written Finnish, colloquial forms and selkokieli (Easy Finnish) is an edit: recorded as a proposal, never made silently.
Check finished work and organize issues—without touching the files. A hyphens declaration is no proof that Finnish was hyphenated correctly, so the rendered result is checked browser by browser. Long words are tested in inflected forms at 320 CSS px and 200% zoom, and essential details—dates, prices, venues—never rely on decorative or image-only type.
DESIGNED FOR THE MESSAGE
KUMIHAN｜Rytmi doesn't dictate a finished look. It gives AI the knowledge to adapt to each medium and brief. There is no single “Finnish” typeface or Nordic-minimal formula: Fraktur gave way to Antiqua gradually, and today public interfaces, newspapers, hand-lettered festival identities and brand letters drawn from old shop signs coexist. Typefaces are compared by Text or Headline design, weight, width, version and licence.
From scoping the work to web, documents, and review.
Scope purpose, audience, medium, the role of each block (reading, interface, figures or display), register (standard, colloquial or selkokieli) and authorized edits before designing, then route the work to web, documents or review.
Typography and design for Finnish websites, articles, landing pages, and UI, with guidance on long compounds and inflected labels, hyphenation at compound boundaries, and number, date and price formats.
Structure and readability for reports, business documents, and slide decks, with guidance on ”…” quotes, tabular figures, reopening exports to check copy, search and reading order, font licences and PDF text extraction.
Review typography, information, and layout without editing source files, with findings tied to rule and source IDs.
Setup varies by tool. Pick the guide for yours, then choose the skills you need.
v0.1.0 contains 42 rules, four skills and 15 versioned archives (published in the repository; no GitHub Release yet). Native proofreading, live rendering and AI host installation remain unverified.
