18 generators and 11 optimizers for major ad platforms, using your own AI provider key.
OpenAdKit is an MIT-licensed, browser-only toolkit for writing and optimising ads across Google, Meta and other platforms. It suits freelancers and small teams who want free ad copy tools with their own AI key.
What it is
The README lists 18 generators, 11 optimizers and nine supported AI providers, including Claude, GPT, Gemini and Groq. Your key and history stay in your browser, with no backend, no accounts and no telemetry; campaigns export as Markdown or JSON.
Who it's for
Suits freelancers and small teams writing paid-social and search ads. It does not suit teams that need shared workspaces or long-form content, and it is a young project with few contributors.

- One-line installer and a Windows OpenAdKit.bat launcher.
- Covers several ad platforms in one tool.
Where it falls short
- Young project with few stars and contributors; expect limited support.
- Needs Node.js 20+ and your own API key from a provider.
- Focused on ad copy; it does not write long-form articles.
