Design System
Tell Seba what you’re building and it proposes a complete design system — type scale, color, spacing, components, motion — with the reasoning behind each choice. You get a spec doc to implement, billed per run.
A coherent system to implement, not a mood board
A complete, opinionated system
Type scale, color roles, spacing grid, component patterns and motion — one coherent system where every choice supports the others, not a pile of options.
The reasoning, written down
Seba explains why each decision works for your product and audience, so your team can defend it and extend it instead of guessing later.
Anchored to one memorable thing
Every choice serves the single impression you want to leave. A system that tries to be memorable for everything is memorable for nothing.
Just describe the product
No tool to set up. Tell Seba what you’re building and who it’s for in Telegram — the spec comes back as a file, billed per run.
What the design system covers
The same framework a senior product designer applies, in one pass.
- Aesthetic direction — the memorable thing every decision serves
- Typography — typeface choices, type scale, weights, line-height, hierarchy
- Color — base, surface, accent and semantic roles, light and dark
- Spacing & layout — a consistent grid, density and rhythm rules
- Components — patterns for buttons, inputs, cards, navigation and states
- Motion — when to animate, easing and duration, what stays still
- Competitive landscape — what category leaders do and where to break from them
- Implementation notes — tokens and structure so devs can build it cleanly

Describe the product
“Design system for a dev-tools dashboard, dark, serious.” Share a repo or a live URL if you want it grounded in what exists.
Get the spec
Seba proposes a full system with reasoning and returns it as a spec doc you implement, with the exact credit cost shown up front.
When to build a design system
Get a coherent foundation before the UI sprawls.
- +Starting a new product with no design language yet
- +Replacing ad-hoc styles that drifted across screens
- +Aligning a team on type, color and spacing rules
- +Giving a developer a clear spec to build against
- +Rebranding and needing a fresh, consistent system
- +Setting design tokens before scaling the component library
Frequently asked questions
What does the design system include?+
Aesthetic direction, typography, color, spacing and layout, component patterns, motion, plus implementation notes. Each decision comes with the reasoning so your team can extend it.
Does Seba implement the design for me?+
No. Seba returns a spec doc — the system and the reasoning. You or your developer implement it in code. Seba does not build, deploy, or touch your repo.
What does Seba work from?+
A description of your product and audience is enough. Share a public repo URL or a live site and Seba grounds the proposal in what already exists.
What format is the deliverable?+
A structured spec file you can read or hand to a developer. Ask for design tokens, a component checklist or a one-page summary and Seba formats it that way.
Can I push back and adjust it?+
Yes — it’s a proposal, not a verdict. Tell Seba what to change (warmer color, different type, denser layout) and it revises the spec.
How much does it cost?+
You spend credits per run, and Seba shows the exact cost before it starts. Start free with welcome credits; credits never expire.
