Base44 and LazySusan are often mentioned together, but they solve different problems. Base44 is built for creating apps with AI. LazySusan is a workspace for using the leading AI models directly.
Primary purpose
If you want to build and ship an app with AI inside it, an app-building platform is the right category. If you want to write, research, design and produce with AI, a model workspace is.
Model access
LazySusan gives you chat models from OpenAI, Anthropic, Google, xAI, DeepSeek and Perplexity, plus image, video and voice models, in one place.
Learning curve
LazySusan works like a chat app: choose a model and start. There is no platform to learn beyond the models themselves.
