PartyRock is a good place to start generative AI experimentation. It's got a no-code interface, a Trophy Generator for developing and refining ideas through chat-based interactions, and a Featured Apps gallery. You can publish your own apps, discover and remix others', and join a Discord Community for socializing. It's good for beginners and more advanced users who want to try generative AI and prompt engineering.
Another good option is Riku, which lets you build, test and run AI apps without programming. Riku gives you access to more than 40 large language models so you can build chat, text, vision and image apps. Among its features are fast app creation, real-time human feedback and integration with tools you already use. It's good for automating tasks, testing ideas and streamlining workflows.
