For engineering and platform teams
Add typed AI decisions to your own tools
Ask bounded questions over an API and get a probability for every option, with keys, budgets and rate limits per project.

The problem
Calling a chatbot from internal tools returns free text you can't test, cap or audit.
The result
AI answers your code can rely on, with limits you control.
How FitRank does it
- 1Create a project and an API key in the admin area.
- 2Call a question by name with its inputs. Each question has a fixed list of options; you get back a probability for each option, or an abstain when the model isn't sure.
- 3Every call is logged, rate-limited and counted against a monthly budget.
The features that do the work
- Decision APIYour own services ask FitRank typed questions over an API and get a probability for every option, with per-project keys, rate limits and budgets.
In-house decision modelMatching runs on a small transformer distilled from an open-weight LLM. It runs on an ordinary CPU, costs nothing per run and is calibrated per company.
