The AI layer between your software and every model.
Rana Brain is a set of OpenAPI endpoints that sit between your application and the AI vendors. It makes each call cheaper, checks the answer, and keeps a record you can audit.
What every call gets
Model routing that cuts cost
Each request goes to the least expensive model in our evaluated pool that can answer it well. If a provider has an outage or rate-limits, the call falls back automatically.
Every response graded
Answers are scored before they are billed. One that falls below the quality bar is retried on a stronger model, and you are not charged for the weak one.
Prompt optimization
Optionally rewrites a vague prompt around role, task, audience and format. Turn it off when exact wording matters, as in legal text or a carefully worded customer message.
Prompt caching
Shared industry instructions and your company context are layered so the stable parts are cached. Your questions, data and answers never are.
Context from your own data
Rana Dive answers plain-English questions with numbers computed by SQL on your systems. The AI decides what to ask; your database decides what the number is.
Governance and replay
Conversation threads stay on one model, so they can be replayed. Payloads are encrypted at rest and can be opened one at a time through an audited endpoint.
Budgets at every level
Set spend and request caps for the company, each sub-account and each user, by hour, day, week or month. The cap is checked before the call is made, not after.
Usage you can resell
Usage is reported per request and per sub-customer, so partners can bill their own customers with their own markup.
One key, many vendors
Claude, ChatGPT, Gemini, Copilot models on Azure, and more, through one authenticated API and one bill. Choose a vendor yourself, or let Rana choose for you.
