The planning studio for AI systems

Plan the AI stack before you pay for it.

Sketch a multi-model workflow, describe its traffic, and get an immediate monthly cost range—without connecting a provider account or running a single prompt.

How forecasting works

One system view from idea to operating cost.

01

Map the workflow

Connect routing, specialist, and fallback models as a real directed graph.

02

Set the operating envelope

Model low, expected, and peak traffic with tokens, retries, caching, and infrastructure.

03

Make the tradeoff visible

See cost by node and provider, catch invalid branches, and share a defensible estimate.

Free account

Free to use. Nothing to upgrade to.

Budget Studio has no paid tier. Sign in with an email link and you have all of it — the studio makes its money building the systems this tool helps you plan.
