Dyad is a local, open-source AI application generator that allows users to build their own apps without writing code or spending money. It works on Linux, macOS, and Windows, and users can choose to use either local AI services (which run on their own devices) or free online services. Dyad's GitHub page describes it as "fast, confidential, and completely under your control," similar to other AI tools like Lovable, v0, or Bolt, but with the added benefit of running directly on the user's computer. This local setup is especially important for privacy, as it keeps data and processing on the user's device rather than in the cloud. To use Dyad, users first need to install it on their operating system by downloading the appropriate installation file from the official Dyad website. On Linux, this can be done through package managers or graphical tools like GearLever, with options to download RPM, DEB, or AppImage files. Once installed, users can connect Dyad to an AI model by accessing the "Model Providers" section in the settings. They can either use pre-existing models or add a custom provider, particularly useful for local AI setups where users must download and select a model that is compatible with their system and capable of coding. The CodeGPT page is a helpful resource for finding the right model. Creating an application with Dyad is straightforward. Users can click on the Home icon in the sidebar and select "New Application," which opens a familiar AI chat interface. Here, they can describe the app they want to build, being as specific as possible. For example, a user might request an app that helps mature women regain their femininity by offering advice on clothing, makeup, and styling. The user could also specify that the app should be installable on Linux desktops via AppImage and include features to save user preferences. After entering the description, users can press Enter or click the right arrow to start the creation process. Dyad will then process the request, and users may be prompted with additional questions, such as how to connect the app to a database. If users exceed the free AI service’s request limit, they must wait a day or purchase credits. However, Dyad remains in a suspended state, allowing users to retry the process later. Once the app is compiled, users can test it within Dyad to ensure it works properly. If they are satisfied, they can publish the web application on GitHub, clone it, and run it locally. Dyad also offers a Pro license for $20 per month, which includes access to more AI models, an advanced agent mode, and automatic debugging features, enhancing the development experience for more complex projects.
