Oprill / Developer platform
Design around context, not isolated prompts.
Explore the responsibilities an application would need to retrieve evidence, prepare an answer and respect the user’s authority.
Product concept · Interactive website preview
Ask for evidence with a clear boundary.
A retrieval request needs a subject, an authorized identity and a scope. Return provenance with the result so the application can explain it.
Explore retrieve
This is an architectural contract, not a documented Oprill API. No endpoint, token or SDK is provided.
The design returns selected passages with their source references.
Illustrative exampleKeep the application in charge of the experience.
Separate source retrieval from the view that presents the result. The application can decide how to show uncertainty and when to request review.
Explore compose
An implementation must handle an empty result and an unavailable source. Neither condition should become a fabricated answer.
The interface keeps source references beside the proposed brief.
Illustrative exampleCarry authorization through the full request.
A backend task should not gain broader access than the person or service that initiated it. Check the boundary again when results are used.

The preview illustrates application design only. It does not offer credentials, authentication or an operational developer platform.
The design maintains the same scope through the workflow.

Questions about developer platform
Can I request an API key here?
No. This page explains an application design concept. Oprill does not provide a running API or credentials through this website.
What should an application do with no evidence?
Show that the requested evidence was not found and ask for a narrower question or an authorized source.
Understand the concept. Keep the decision.
These original examples explain a possible approach to developer platform. Oprill’s website does not run AI agents, connect to company data or carry out external actions. Your selections stay in this page and reset when you reload.
