How it works

Three steps. You only see one of them.

01
You ask a question
Type anything — a coding problem, a creative prompt, a factual question. Exactly as you would with any AI.
02
Split classifies it
A lightweight classifier reads your prompt and identifies what kind of question it is — in under 500ms, before you notice.
03
The best model answers
Your question is routed to whichever AI performs best for that category. You get one answer — the right one.
Why Split

No single AI wins everything.

Claude is exceptional at code and nuanced writing. GPT-4o excels at structured reasoning and math. Gemini has deep general knowledge and real-time web access. You shouldn't have to choose — or even know the difference.

One interface, every model
Stop switching tabs. Ask anything in one place and let the routing handle the rest.
10–50× cheaper than running all models
Routing directs simple questions to fast, cheap models. You only pay for the power you actually need.
No model bias
Most people pick one AI and stick with it — even when it's the wrong tool. Split removes that ceiling.
