Toolkit.fun evolves into a workspace for AI tools and workflows

Toolkit.fun has grown beyond a collection of online utilities. Its latest update turns the product into a workspace where people can discover tools, compose workflows and bring repeatable AI work into their teams.

Toolkit.fun

One place to build and run

The redesigned Workbench keeps active tools and workflows close at hand, while Studio provides a clearer path from an idea to a reusable tool. Library previews make it easier to understand a tool before opening it, and signed-in users now move directly into their working environment.

Introducing aiplans.dev — clear AI pricing across providers

AI pricing changes quickly and rarely fits into one simple table. Official APIs, cloud marketplaces and aggregators all package the same models differently.

aiplans.dev brings those choices into one focused comparison experience. It helps developers and teams compare subscription plans and API pricing across more than 30 providers.

What it brings together

  • Prices for the same model across official and third-party channels
  • Subscription plan features and billing periods
  • USD and CNY views, plus regional availability
  • Community offers and source links
