How much can your team save by moving from Anthropic to open‑weight models?
Add costmaxxing to Chrome as a claude.ai Owner, and your team's real bill opens on its own: every person, product, and model at Anthropic's API prices, next to the same usage on open‑weight models.
It runs in your browser. Nothing is uploaded.
