What lttr/corp does

LTTR/CORP (legal entity: Letterink s. r. o.) is a privately held software company founded in 2017 and headquartered in Trstená, Slovak Republic, with operations also in the Czech Republic. The company develops LTTR/INK, a vector stroke engine delivered as plugins for Adobe Illustrator and the Glyphs desktop app, targeted at professional type designers, letterers, and calligraphers. Its core technological contribution is the commercial implementation of the "skeleton type design" methodology — an approach that builds letterforms by applying stroke characteristics to skeleton vector paths, extending Gerrit Noordzij's "The Stroke – Theory Of Writing" with a novel stroke contrast tilt technique. Core capabilities include independent per-curve-point stroke characteristic control, clean stroke-to-outlines vectorization, reusable Stroke Styles, stroke interpolation between masters for parametric font design, and combined stroke/outline workflows supporting Latin, Chinese, and Arabic scripts.

The company's product suite comprises the two LTTR/INK plugins (Glyphs version released July 2021, Illustrator version released September 2023 after a 2022 Adobe development grant), the LTTR/INK Academy (workshops including Initiation, Skeleton Empowerments, and Parametric Type Design), and three sub-brands (LTTR/FACE, LTTR/SET, AI Fonts) at varying stages of maturity. Distribution is product-led and self-serve, with plugins listed on Adobe Creative Cloud Exchange and the Glyphs Plugin Manager and a 7-day free trial available via direct website download.

Revenue is generated through a dual licensing model combining perpetual licenses (€50 Acolyte, €120 Master) with optional annual update subscriptions (€90/year, or €37.50/year for discounted-tier holders) and a pay-what-you-can sliding subscription ranging from €25/year for students and low-income users up to €300/year for high-earning supporters. A separate Disciple tier at €30/year serves verified students, and Guild organization licenses are negotiated via direct inquiry. The company has not raised institutional venture or growth capital; the only disclosed external capital is an undislosed-amount Adobe grant in 2022. Customer segments are primarily individual professional type designers and letterers, with secondary segments in design studios, educational users, and workshop organizers — served almost entirely through long-tail, low-ACV transactions.

Core offering

LTTR/CORP develops and sells LTTR/INK, a vector stroke engine delivered as plugins for Adobe Illustrator and the Glyphs font editor. Using a proprietary skeleton-based type design methodology, the plugins let type designers and letterers draw high-quality calligraphic strokes as vector path skeletons and apply independent stroke characteristics to convert them into accurate outlines for typefaces, lettering, and calligraphic work.

Product overview

LTTR/CORP (Letterink s. r. o.) offers LTTR/INK, a vector stroke engine specifically designed for type design and lettering. The product suite consists of two core plugins: LTTR/INK for Adobe Illustrator and LTTR/INK for Glyphs app. Both products implement the skeleton type design methodology pioneered by the company, allowing users to draw vector paths as skeletons and apply stroke characteristics to generate letterforms. The Adobe Illustrator plugin focuses on vector stroke creation and outline conversion for lettering and calligraphic work, while the Glyphs plugin extends this capability to font production with advanced features like stroke interpolation, stroke styles, and font export. The company also operates the LTTR/INK Academy providing educational workshops, and maintains related projects under the LTTR/FACE, LTTR/SET, and AI Fonts sub-brands.

Expansion highlights5 records

Others

• Glyphs: Professional macOS font editor widely used by type designers and foundries. LTTR/INK operates as a plugin within the Glyphs app, making Glyphs a key distribution platform and integration partner rather than a direct competitor in the same product surface.

Direct peers

• RoboFont: Professional font editor built on a UFO-based workflow and Python scripting, targeting the same type designer community as LTTR/INK. Comparable subscription pricing and advanced tooling, though RoboFocus on outline-based editing while LTTR/INK emphasizes skeleton stroke design.
• FontLab: Long-established professional font editor used by type designers and foundries for more than 25 years. Comparable in target market and premium commercial model, with traditional outline-based editing rather than LTTR/INK's skeleton stroke approach.
• FontForge: Open-source font editor used by independent type designers and hobbyists. Overlaps with LTTR/INK in core functionality (vector font creation) and target users, but is free and open-source versus LTTR/INK's commercial plugin model.
• Astute Graphics: Premium plugin suite for Adobe Illustrator that extends vector design capabilities (Phantasm, MirrorMe, InkScribe, etc.). Highly comparable to LTTR/INK in business model, Illustrator user base, and premium plugin pricing approach.
• Fontself: Plugin for Adobe Illustrator and Photoshop that enables designers to create custom fonts directly within Adobe apps. Directly comparable to LTTR/INK's Illustrator plugin, with overlapping customer base of designers and letterers seeking in-app font creation.

Emerging players

• Calligraphr: Web-based tool for creating custom fonts from handwriting samples and drawings. Overlaps with LTTR/INK's calligrapher and letterer customer segment but uses handwriting digitization rather than vector stroke design, positioning it as a complementary rather than competing tool.
• Birdfont: Free font editor for creating TTF, OTF, and SVG fonts across Windows, macOS, and Linux. Targets a similar type design customer base to LTTR/INK but as a free open-source alternative rather than a premium professional product.
• FontStruct: Web-based font builder using geometric shapes and a community sharing model. Addresses the same end user interest in custom font creation as LTTR/INK, but with a free, web-based, community-driven delivery model rather than a professional plugin.
• Prototypo: Web-based parametric font design tool with customizable variables for shape generation. Overlaps with LTTR/INK's stroke interpolation and parametric type design features, but delivered as a web app rather than a plugin for Adobe Illustrator or Glyphs.
