Open CoDesign

Overview

Open CoDesign is an MIT-licensed desktop application for AI-assisted design. It turns a prompt into a polished prototype, slide deck, or marketing asset using the model provider you choose, while keeping designs, prompts, and settings on local disk. Version 0.2.0 introduces Agentic Design with workspace-backed sessions, permissioned local tools, lazy skills, and DESIGN.md design systems.

Key Features

• Bring your own model: Anthropic, OpenAI, Gemini, DeepSeek, OpenRouter, SiliconFlow, local Ollama, ChatGPT subscription login, or an OpenAI-compatible relay.
• Local-first workspace: designs, prompts, and settings stay on disk, with sessions stored in JSONL and generated sources kept in real workspace files.
• Agentic Design in v0.2: each design is a long-running session with a real workspace where the agent can read, edit, run permissioned tools, and preview its work.
• Twelve built-in design skill modules plus project-level SKILL.md support, with DESIGN.md storing brand values and design tokens.
• Region-level comments, AI-tuned sliders, instant switching among recent designs, and responsive desktop, tablet, and phone previews.
• On-device exports to HTML, PDF via local Chrome, PPTX, ZIP, and Markdown.

Use Cases

• Generate landing pages, dashboards, pricing pages, pitch slides, mobile app screens, chat UIs, calendars, blog articles, receipts, portfolios, and email designs from prompts.
• Refine generated artifacts through inline comments and AI-emitted sliders, then export to HTML, PDF, PPTX, ZIP, or Markdown.
• Prototype connected local app journeys with navigation, shared records, validation, empty states, and success states.
• Use a preferred API provider, ChatGPT subscription, or local Ollama for local-first design work without subscription lock-in.

Getting Started

• Install via Homebrew Cask on macOS, Scoop on Windows, or direct downloads for macOS, Windows, and Linux from GitHub releases.
• On first launch, add a provider by signing in with ChatGPT, pasting an API key, or selecting local or keyless Ollama or an OpenAI-compatible gateway.
• Pick one of fifteen built-in demos or describe your own prompt; a sandboxed prototype appears in seconds.
• Refine with comments, sliders, and local files, then export the result.

Deployment & Requirements

• Runs on macOS 12+ (Monterey or later), Windows 10+, or Linux with glibc 2.31 or later.
• Requires one API key, ChatGPT subscription sign-in, or local Ollama.
• PDF export uses your local Chrome.
• Credentials are stored in ~/.config/open-codesign/config.toml and the ChatGPT OAuth token store under the app config directory.

Before You Adopt

• License: MIT. Review its terms before using, modifying, or distributing the project.
• Installers are not notarized or Authenticode-signed yet, so macOS and Windows may show security warnings.
• PDF export depends on the local Chrome installation.
• No account is mandatory and telemetry is off by default.
• Generated artifacts are interactive prototypes, not production services; data and service actions are simulated and state may reset on reload.
