Drop-in AI middleware
The optimization layer your AI calls are missing.
Point your existing OpenAI or Anthropic SDK at Multra.ai. It compresses context, routes to the cheapest capable model, and verifies quality — then returns the same answer with a savings receipt.

Free Audit
Your first Savings Receipt in 3 steps.
The same guided path you follow in the app: connect a provider, send one real prompt, then read the receipt.
Connect OpenAI or Anthropic
Paste an API key from the provider you already use. Multra.ai tests it live and stores it encrypted.
↳ Keys never appear in logs or receiptsRun one real prompt
Ask anything you would send to GPT-4o or Claude. Open the side-by-side Optimization Receipt to compare route, tokens, and cost.

Each top-nav page has its own guide. Start here, then open the page that matches your work.

Every number shows its evidence.
Each receipt labels every value with one of the four tiers above. When pricing isn't available, Multra.ai says so — it never rounds a missing cost to zero. When a request costs more, that loss shows up in your total too.
Individual results vary by task, model, and provider pricing. Multra.ai shows negative savings when a call costs more — never cherry-picked averages.
Free Audit includes Chat and the text API. Coding agents and Develop require Pro.
