Bubble

The content describes three different entities: a personal accountant offering low-cost tax and budget advice, Oz - Plaid for LLMs, and Bubble, a no-code web application builder.

The content provides limited information on how to use each service. For the accountant, presumably you would contact them for tax and budget advice. For Oz, you would integrate it with your LLM. For Bubble, you would use their point-and-click interface to build a web application.
