TanStack is one of the fastest-growing JS frameworks in the world.
375M weekly downloads.
Used by teams like Anthropic.
Tons of new launches like TanStack AI SDK
And now their docs have a grounded AI agent powered by
@kapa_ai.
Why?
Because
@tan_stack ships.
The docs change constantly. The product evolves constantly. And if developers - or AI coding agents - are not reading the latest docs, they get left behind.
That leads to outdated answers, poor implementations, and a lot of wasted time.
So the TanStack team needed an AI assistant that could:
โ Index thousands of docs pages in real time
โ Give answers grounded in official sources
โ Cite where the answer came from
โ Say โI donโt knowโ when the docs donโt support an answer
โ Help the team spot gaps in their documentation through analytics
Thatโs now live.
Huge credit to Anton Malling from kapa team and
@tannerlinsley for the awesome deployment. We're just getting started!
