Write your pricing, eligibility or fraud policy in plain English. SmartDecision turns it into a decision table your team can read and change, and your apps can call. It runs on your own servers.
Timing Recorded from production Live
Four product decisions, answered by one production instance
Last request
Each row is one request of 30 input sets to a production SmartDecision instance (Hetzner CX33, Falkenstein), timed with the network included. This replays a recorded session; run it live to time four requests from your browser.These requests were timed in your browser.
In the demos, real products ask SmartDecision for every answer, from a 251-rule ticket price table to a five-step claims chain. Open one and change the rules yourself.

The sentence your team writes, the table it becomes, and the call your app makes.
A loan is approved if credit score is 700 or higher, age is between 21 and 65, and income is at least €10,000. Scores from 650 to 699 go to manual review.
As your team writes it. The built-in AI drafts the table on your server.
| credit-score | age | income | loan-status |
|---|---|---|---|
| >= 700 | 21...65 | >= 10000 | Approved |
| 650...699 | * | * | Manual Review |
| * | * | * | Rejected |
* is any value. Checked top to bottom; the first match answers.
POST /api/resolve/214
credit-score = 712
age = 34
income = 18000{
"output": {
"loan-status": "Approved"
},
"rule": { "position": "1" }
}The answer names the rule that matched, so every result can be traced.
No AI at runtime. Same inputs, same answer, every time.
Pricing tiers, eligibility checks, fraud thresholds, approval limits. Each one starts as a simple
if and ends as nested logic nobody wants to touch. The people who own the policy can't read it,
and every change waits in the engineering queue.
SmartDecision moves the policy into a table its owner can read, test and change. Your code keeps one call.
if (score >= 700) {
if (age >= 21 && age <= 65) {
if (income >= 10000) {
return "Approved";
}
}
} else if (score >= 650) {
return "Manual Review";
}
return "Rejected";Four things that keep a quick change from becoming an incident.
Save the answers you expect next to the rules. Every edit is checked against them before you save.
| Input | Expected | Gets | Result |
|---|---|---|---|
| score 720 | Approved | Approved | Pass |
| score 690 | Manual Review | Approved | Fail |
| score 640 | Rejected | Rejected | Pass |
Change a decision that has answered requests in a way that would break them, and saving makes a new version. Apps that don't ask for a version keep the old one until you retire it.

The rule engine, the console and the built-in AI that drafts your rules all run inside your network. Credit scores, transaction amounts and eligibility inputs never leave it, when you write a rule or when an app asks for an answer.
