Question: Is there a way to access multiple AI models from a single interface without having to pay for separate subscriptions?

One good option is MindStudio, a no-code AI application development platform that lets you build your own custom AI tools and automations without writing any code. It can combine models for your own AI assistant and integrate with other data sources. The service has tiered pricing, including a free starter plan, so it's good for a variety of needs and budgets.

Another good option is the AIML API, which offers a single interface to more than 100 AI models through a single API. The API includes serverless inference and a pay-by-token pricing system that's designed to be economical. It's designed to scale up and down reliably, which is good for serious machine learning work.

If you want something a bit more focused, Invisibility is an AI-powered chat interface built into Mac OS that serves as a personal productivity assistant. It lets you work with multiple AI models in one interface, and it can streamline your work with features like selective app sharing and quick information retrieval with keyboard shortcuts. It's good for people who want to integrate AI into their workflow without the hassle of multiple subscriptions.
