Sibr glossary: SIBR, escrow, screeners and more

This glossary defines the words you will meet on Sibr, in plain English. Each term links to a guide with more detail.

Sibr is a polling, survey and paid-study app on the Internet Computer, open to Pi Network users and everyone else.

What is SIBR?

SIBR is Sibr's in-app credit. You can buy it with Pi in the Pi Browser, earn it by answering paid surveys and studies, and spend it on extras such as survey rewards, poll boosts and country targeting. It is not money, has no cash value, cannot be withdrawn and cannot be exchanged back into Pi or any other currency. More in Paid surveys with Pi.

What is escrow?

Escrow means funds set aside up front for one purpose. On Sibr, when you publish a survey with rewards or a paid study, the full budget leaves your balance and is held for it. Respondents are paid from it, and anything unused returns to you when the survey or study ends or is closed.

What is a study?

A study is a paid survey listed on the Earn page for verified humans. It adds a consent step, optional screener questions and quotas, attention checks, a platform fee on top of pay (currently 20%) and a review window for flagged answers.

What is a screener?

A screener is a question at the start of a study that checks whether the study fits you. If your answer does not qualify, the study ends early. A study can have up to 5 screener questions, and they must be choice questions.

What is a screen-out fee?

The screen-out fee is what a respondent is paid when a screener or a full quota ends their study early. It is required in Earn studies with screeners: by default 10% of the study's pay, and at least 0.1 SIBR.

What is a quota?

A quota caps how many people with a given screener answer can take part, for example at most 50 people who choose "Student". When a group is full, new people in that group are screened out and paid the screen-out fee.

What is an attention check?

An attention check is a question with one obvious correct answer, such as "Select Blue for this question", used to spot people who answer without reading. Studies can have up to 3. Failing one in a study under 5 minutes, or two in a longer study, holds the answers for the creator's review instead of paying them at once. More in How to get honest answers.

What is a verified human?

A verified human is an account tied to one real, identity-checked person. On Sibr, every account signed in with Pi counts as a verified human, because Pi Network only lets identity-verified people hold an account. Only verified humans can earn. More in Verified human respondents.

What is a consent use?

A consent use is one way a study may use your answers: research, AI evaluation, a public anonymised dataset, quotes without your name, or AI training. Research is always part of a study. Optional uses start unticked, and AI training is always its own separate choice. More in How Sibr protects respondent privacy.

What is a held answer?

A held answer is a study response flagged by an attention check or by being far too fast. The creator approves or rejects it with a reason. If the creator does not decide within the review window, 7 days unless set between 3 and 14, it is approved and paid automatically.
