A survey language you already know.

Designed for researchers, not programmers.

Think about your survey, not your syntax.

AEL (AlphaQ Expression Language) is the built-in language of AlphaQ for expressing questionnaire logic, validation rules, dynamic coding, and survey flow.

Unlike general-purpose programming languages, AEL was designed around the way survey researchers naturally think. Instead of learning programming syntax, you simply express the conditions and rules of your questionnaire.

Why AEL?

Most survey systems eventually force users to think like programmers.

• Skip logic
• Goto statements
• Script languages
• Complex branching

AEL takes a different approach.

Instead of asking "Where should I go?", AEL asks

"When should I ask this question?"

Survey logic becomes declarative rather than procedural, making questionnaires much easier to read, maintain and modify.

Familiar From the First Day

AEL intentionally uses expressions that already feel familiar.

#gender = 1

#age >= 20

#income > 5000

3 ~ [#car]

[1..5]

[#12,#13]
