Adaptive product intelligence

Don't write a PRD.
Decide one.

Start with your own explanation of the product. Briefion turns that context into adaptive options, follows every answer, then assembles a PRD your team can build.

How it works

From uncertainty to
build-ready clarity.

No fixed questionnaire. Briefion follows the strongest unresolved decision.

01

Explain

Describe what you want to build in your own words.

02

Choose

AI turns that brief into one recommendation and two credible alternatives.

03

Clarify

Every answer changes the next question and available options.

04

Unlock

Free users see an abstract. ICXHNK Credits unlock the full PRD package.

One decision system

Master direction.
Supporting detail.

Master and Supporting PRDs are generated from the same recorded decisions, keeping package context consistent.

  • Facts, assumptions, and decisions stay separate
  • Master sections share one decision context
  • Supporting PRDs include testable requirements

Protected by design

Abstract first.
Full value stays server-side.

Unpaid sessions never receive full PRD text. Paid views use access checks, dynamic watermarking, and copy deterrence.

Websites cannot guarantee blocking operating-system screenshots. Briefion says that clearly.
