Tailwind is a social media and email marketing platform used by over a million brands and small businesses. When AI content generation became genuinely useful, Tailwind needed a strategy for integrating it — not as a marketing feature bolted on the side, but as something that improved the core product experience for users who were already there to create content.
We designed two things: GhostWriter, an AI writing tool embedded directly in the email editor, and Labs, a modular environment for surfacing new AI capabilities without requiring a full product integration each time.

AI content tools fail when they require users to leave their context to use them. If a marketer is building an email in Tailwind and needs to generate copy, they shouldn’t have to open a separate tool, generate text, and paste it back in. That was the workflow most platforms had in 2022 — and it was slow and disjointed.
The brief for both GhostWriter and Labs was the same underneath: AI should show up where the user already is, at the moment they need it, rather than requiring them to navigate to a separate destination.
GhostWriter sits inside the email editor. When a user is about to write body copy, the AI option is already there — no mode switch, no separate screen. The user provides a prompt or lets GhostWriter infer from campaign context already in the system (subject line, audience, campaign type), gets a draft back, and edits from there.
The draft appears in place and is immediately editable. The experience was designed to feel like a smart collaborator alongside the writing process, not a separate tool you consult and copy-paste from.
Design challenge: generated text is variable in length and quality. We had to design for the full range — a great draft that needs minor tweaks, a draft that needs significant reworking, and a draft that misses entirely and needs a new prompt. The interface handles all three gracefully without making the simple case unnecessarily complex.
Subject lines are high-stakes — they determine open rates and benefit from testing and iteration. We designed the subject line generator to produce multiple options simultaneously rather than one draft at a time: direct, curiosity-based, emoji-led, question format. Users can see several approaches and choose or iterate from the one closest to what they want.

The product team was adding AI capabilities faster than the core product could absorb them. Without a designated place, AI features would spread inconsistently across the product, each with its own interaction pattern and its own discoverability problem. Labs was designed to be that designated place.
The core structure of Labs is the Lab Card — one card per AI capability. Each card gives users enough context to understand what the tool does and lets them launch into using it. The card structure means new capabilities slot in as new cards without requiring a navigation change or a redesign.
Cards at launch included:




Labs also ships as a browser extension — giving users access to the AI toolkit without being inside Tailwind at all. Someone drafting a social post on LinkedIn or a product description in their e-commerce platform can use the Labs tools from the extension without switching context. This extended the reach of the AI capabilities beyond Tailwind’s own surfaces without requiring users to change their workflow.

GhostWriter and Labs shipped to Tailwind’s full user base. Users who had been leaving the platform to generate content elsewhere had a reason to stay inside the product. The Lab Cards structure gave the product team a framework to ship new AI capabilities incrementally — which proved prescient as AI content tools continued to develop rapidly after launch.

★★★★★
I had the pleasure of working with Gytis for a long time, and he has consistently been one of the most thoughtful and dependable product designers I’ve worked with.
Gytis thinks deeply about the product, the user, and the business context behind every design decision. He is very strong at turning ambiguous ideas into clear, polished, usable experiences, and he brings a high level of taste and discipline to the work.
Gytis is someone I could trust with important product problems. He communicates clearly, takes feedback well, and has a calm, mature way of moving projects forward even when the direction is still evolving. That combination of creativity, judgment, and ownership made him a real partner to the product team!

I'd recommend Gytis Mark without hesitation to anyone looking for a designers who treat their work like it's their own."
Projects
Tailwind had email but no campaign automation. We designed the full system from scratch — a campaign dashboard, a template library with the most popular automations first, and a linear builder where step details open in a side panel without ever losing sight of the flow diagram.
Over six months we worked across the full product — shipping an admin dashboard, Protau adaptive testing, a KTU research experiment on motivational feedback with real students, and a broader restructure to make the growing app easier to use and more data-driven.
Cohere had strong vendor intelligence but the product didn't reflect it in demos. We redesigned the platform twice across four user types, built the design system from scratch, and contributed to product strategy and roadmap decisions throughout the two-year engagement.
Mintra's Training Portal needed a design overhaul alongside several new features. We designed the question bank management system, the exam builder, the Crew Evaluation Test with role-based question assignment, a proctoring and identity verification system, course reporting, and the student test interface.
