Start from real source material
Create or update a model.
AI Assistant reads the policy or spreadsheet, then builds a complete new model or maps a revised policy to exact proposed edits.
New decision model Spreadsheet Update
Turn a revised policy into exact model edits.
AI Assistant maps the policy to proposed changes in the existing model. Review each change before it touches the logic you already use.
Exact model diff 
Revised policy AI-assisted validation
Generate tests. Catch mismatches.

Frequently asked questions
What to know before you try AI Assistant.
01 Do I need Aletyx Decision Control to use AI Assistant?
No. You can use AI Assistant directly in Aletyx Playground, the free hosted modeling workspace. AI Assistant itself requires a subscription. Existing Decision Control users can also activate it inside Decision Control.
02 Is Aletyx Playground free?
Yes. Aletyx hosts the Playground at no additional charge. AI Assistant requires an active subscription and is subject to usage limits, but there is no separate Playground or hosting fee.
03 Can I run the resulting models outside Aletyx?
Yes. AI Assistant works with the DMN standard. You can download your models and run them in any compatible DMN runtime.
04 What can I use to create a decision?
You can begin with a policy, spreadsheet, prompt, or existing decision model.
05 How does review differ for new and existing models?
For a new decision, AI Assistant generates the complete model as one coherent starting point. There is no per-element approval loop. When changing an existing model, it presents exact diffs so you can accept or revert each edit before applying it.
06 How does AI-assisted validation work?
AI Assistant helps you define the use cases and expected behavior that matter. Automated tests execute those scenarios against the model and show where actual results differ from expectations.
07 How does additional usage work?
AI Assistant combines Aletyx decision-modeling models with frontier AI models. Your subscription includes usage. If you need more, you can purchase additional usage at rates aligned with the frontier models used. Current rates are shown before purchase.
08 What happens after the free trial?
A credit card is required to begin the 14-day trial, but you will not be charged during it. Cancel anytime before the trial ends. Otherwise, the subscription continues at $95 per user per month, plus applicable tax.
09 Will AI Assistant be available in an IDE?
IDE extensions are coming soon. Today, AI Assistant is available through Aletyx Playground and Aletyx Decision Control.
