Moldable

Moldable is a desktop application that lets you build personalized software by talking to it. It runs on macOS and Windows and uses AI to generate applications from your description. The core principle is local-first: all data and code stay on your own machine, which gives you control and ownership rather than leaving everything on a server. You can iterate by continuing the conversation, asking for new features or interface changes, and the app updates in response. The product can be downloaded and used for free.

- Describe an app and have Moldable generate it

- Add features and adjust the interface through conversation

- Preview changes in real time as they are made

- Edit the generated code directly if you have programming skills

- Export and share apps, or extend them with skill plugins

Example uses include a meeting minutes app that records and transcribes audio, a language learning diary with real-time translation, and a to-do manager with priorities and keyboard navigation. The built-in code editor matters for developers who want to go past what the conversation produces. Skill plugins such as PDF extraction, audio transcription, and browser automation extend what an app can do.

- Individuals who want software shaped to their own workflow

- Teams building custom internal tools

- Developers prototyping ideas quickly

- Entrepreneurs testing app concepts

It suits people who are tired of fitting their process into generic tools and would rather build something specific.

Moldable is a desktop application, so it is not available in the browser and depends on your machine's performance. App quality depends on how well you describe what you want, and complex applications may need code editing. The list of supported AI models, such as Anthropic Opus 4 5, OpenAI GPT 5 2, and Gemini 3 Flash, can change over time. Because it is free, there is no service guarantee, so keep backups of anything important.
