OpenCoworkAI/open-codesign

Open Codesign is a local-first, open-source desktop application that converts natural language prompts into prototypes, slide decks, and marketing assets. It allows users to bring their own API keys or existing subscriptions for various AI models without locking them into a single cloud provider.

Project overview

Project type: AI Agent · Workflow
Use cases: Documents & Office · Coding & Development
Deployment: Refer to project documentation
License: MIT

Best for

Creators, developers, and general users who want a local desktop application to generate design artifacts using their existing model provider subscriptions.
Users who need multi-format exports such as HTML, PDF, and PPTX from generated design artifacts.

Key capabilities

Turns a blank prompt into polished prototypes, slide decks, or marketing assets with hover states, tabs, and empty states wired up.
Supports bringing your own model via API key, or signing in with provider subscriptions like ChatGPT. Multi-model support (Claude, GPT, Gemini, DeepSeek, Kimi, GLM, Ollama, etc.).
Workspace-backed sessions with JSONL history, permissioned agent tools (read, write, edit, bash, grep), and visible live streaming tool calls.
Ships with twelve built-in design skill modules (slide decks, dashboards, SVG charts, etc.) to steer models toward high-quality design.
Exports real files in HTML, PDF, PPTX, ZIP, and Markdown formats.
Converts designs into a componentized ui_kits/<slug>/ folder with deterministic and vision verifiers for coding-agent handoff.

Limitations and risks

Installers are currently not notarized or Authenticode-signed.
On macOS Sequoia 15+, standard bypass methods for unsigned apps may fail, requiring terminal commands to open the application.

Getting started

Install via Homebrew, Scoop, or direct download. Open the app and select a provider (API key, ChatGPT sign-in, or local Ollama). Time to first artifact is approximately three minutes.
