ATV Design is an open-source AI design agent for your desktop, built for GitHub Copilot. Turn natural-language prompts into production-ready design artifacts — HTML/JSX prototypes, PPTX slides, or PDFs — in seconds using your Copilot subscription via OAuth+PKCE. All credentials stay local, all processing on your machine. Also supports BYOK for Claude, GPT, Gemini, DeepSeek, Kimi, GLM, and Ollama.
A fast, privacy-first Figma alternative that runs on your laptop, powered by GitHub Copilot. Built on OpenCoworkAI/open-codesign (MIT); ships with premium skill bundles including ui-ux-pro-max and emil-design-eng-inspired.

- GitHub Copilot native — design with your Copilot subscription via OAuth+PKCE. Official SDK, documented flow, no reverse engineering.
- Prompt-to-prototype in seconds — describe your design idea; the AI agent generates interactive HTML/JSX, editable PPTX, or PDF exports instantly.
- 100% local-first, BYOK — no accounts, no proxied APIs, no telemetry. Credentials live in plain-text config on your machine. Self-hosted or bring your own provider credentials.
- Also supports BYOK for other providers — Claude, GPT-4o, Gemini, DeepSeek, Kimi, GLM, Ollama. Switch providers in settings without losing work.
- Design system first — generates and refines
DESIGN.mdbrand systems automatically. Consistent tokens across all designs; edit once, regenerate everywhere. - Extensible with skills — ship with curated skill bundles (UI/UX pro patterns, animation design, and more). Load project-specific or user custom skills on demand.
- Real workspace, real files — designs live in your filesystem alongside
DESIGN.md, assets, and exports. Edit with your favorite tools; re-run to regenerate.
- Official Copilot SDK — uses documented OAuth+PKCE flow. Use your Copilot subscription directly; no reverse-engineered tokens, no account creation.
- Interactive sessions — long-running design conversations with preview, tweak, and regenerate controls.
- Structured input — ask the agent questions; get answers with follow-up suggestions.
- Live preview — see HTML/JSX/CSS render in real-time with error reporting and metrics.
- Also supports BYOK providers: Anthropic Claude, OpenAI (GPT-4o / GPT-4 Turbo), Google Gemini, DeepSeek, Kimi, GLM, Ollama (local), and OpenAI-compatible APIs.
- Switch seamlessly — pick providers in Settings; session history stays with the design workspace.
- No hosted backend — zero dependency on external services. All processing on your machine or your chosen cloud provider.
- Plain-text credentials — API keys stored in
~/.config/atv-design/as readable JSON. No account creation, sync, or vendor lock-in.
- 12 runtime-loaded skill entrypoints — UI/UX pro patterns (colors, components, layouts), animation design guidance, and upstream carryovers.
- ui-ux-pro-max bundle — comprehensive design system patterns, component templates, and reference data.
- emil-design-eng-inspired skill — Emil Kowalski–inspired motion and design guidance.
- Custom skills — load project-local or user-level skills without modifying the app.
- HTML/JSX prototypes — interactive, styled, copy-paste ready.
- PPTX slides — auto-generated presentations with branding applied.
- PDF exports — high-fidelity static documents.
- Design system artifacts —
DESIGN.mdwith extracted tokens (colors, fonts, spacing, scales).
- Ingest brand data — read from URLs, Git repos, or screenshots. Extract and unify color, typography, and spacing tokens.
- Auto-refine — regenerate designs with consistent tokens as your brand evolves.

-
Built-in entrypoints — 12 runtime-loaded skills at
packages/core/src/skills/builtin/*.md:- 4 upstream carryovers
- 7

The upstream Electron + TypeScript + React + Vite + Tailwind + pnpm/Turbo stack is unchanged. We do not fork or migrate the build system.
atv-design uses only the documented Copilot SDK OAuth flow (GitHub docs). The undocumented copilot_internal token exchange used by some third-party reverse-engineered clients is forbidden by our security checklist and blocked by CI at .github/workflows/forbidden-endpoints.yml.
See docs/security-checklist.md for the full audit rules.
