AI platforms, gateways, and APIs

This category is the glue: model APIs, app builders, research notebooks, gateways. OpenAI is the API most tutorials still assume. Dify is an open-source LLM app builder you can cloud or self-host. NotebookLM was renamed Gemini Notebook in July 2026. If you need a coding IDE, go to Dev Tools instead of shopping here.

Dify vs building on the OpenAI API?

Use Dify when you want workflows, RAG, and an admin UI without writing the whole stack. Use the raw API when you already have an app and only need inference.

Is NotebookLM still a product?

Yes. Google renamed it Gemini Notebook on 2026-07-16. Same research tool, more Gemini-app integration. Search both names.

Cloud or self-host?

Cloud is faster to try. Self-host if data cannot leave your network. Dify's community edition is the usual self-host path in this hub.
