Audience response for education and organisations
arsnova.eu brings together live quizzes, numeric estimation questions, confidence ratings on scored questions, a Q&A wall, word-cloud analysis and Pulse Check feedback in one interface for schools, universities, continuing education, workshops and business. Open source, runnable on your own infrastructure and designed for operation with GDPR in mind.
Conforms to WCAG 2.2 Level AA — keyboard, screen reader and individually adjustable response time.
For teaching, training and workshops
From the question to the running session, the flow deliberately avoids unnecessary steps. That is what makes getting started fast and reliable for educators, trainers and facilitators.
Create questions directly or import existing content. Markdown, KaTeX, short answer, numeric estimation, matching, ordering and categorisation are built in.
Start without an account: open a session, choose a style, share a code or QR and use the presenter view if needed.
Participants vote, ask questions and prioritise together. The facilitator and presenter show the quiz, Q&A wall, word cloud, reading phase, countdown, second round and results in one flow.
After the session ends, the results report (PDF) is ready — with learning progress, confidence rating and full question text. In the quiz collection you will find debriefing and PDF for the last run; CSV for Excel under “More”.
What sets arsnova.eu apart
arsnova.eu combines a fast start, pedagogical depth and a transparent technical foundation. The platform stays simple day to day without shrinking what you can do.
Facilitators start without an account. Participants join the session directly with a 6-digit code or QR.
Participants say how sure they are after answering. You spot confidently wrong answers, prioritise the debriefing and export the level of understanding in the results report (PDF).
After the session ends you export a print-ready PDF report with charts, question text and confidence rating. CSV for Excel remains optional under “More”.
Years, orders of magnitude and measurements can be estimated with a reference value, tolerance band, statistics and an optional second round.
MC/SC, short answers, ratings, matching, ordering, categorisation, reading phase, Peer Instruction and presenter mode support learning, training and live facilitation.
Q&A offers pre-moderation, pinning, archiving, up/down voting and sorting by support, quality and controversy.
Free text and Q&A are condensed into words and phrases; the wall weights by agreement, clear majority score or controversy.
Presets, team mode, anonymous mode, nicknames and style choice help from class and seminar to workshop, event and meeting.
Keyboard use, screen-reader status updates, individually adjustable response time and PDF/UA-1-validated results reports — so more learners can join live sessions independently.
Quiz content stays on your device, optional data removal and operation on your own infrastructure give you more control over content and live data.
Docker, Postgres, Redis and an admin activity log make the platform reliable for deployment, operations and auditability.
Structured question types
Three formats turn relationships, sequences and conceptual boundaries into active tasks. Solutions stay hidden while voting is open; model answers and common error patterns appear only after reveal.
Match terms, definitions or examples one to one. The results reveal common mix-ups.
Put steps, events or stages of a process in the correct order. The results show which positions caused uncertainty.
Assign terms or examples to the appropriate categories. The results reveal clear distinctions and common misclassifications.
All three formats are scored. An answer currently receives full credit or no credit; partial credit is not available.
During an active round, correct pairings, target order and target categories remain hidden. The model answer and detailed distributions appear only after reveal.
New in the live quiz
The numeric estimation question is built for years, orders of magnitude, measurements and probabilities. Facilitators set a reference value, allowed input range and tolerance; participants enter only a number.

Print-ready report with learning progress, heatmap and full question text — in the facilitator view and on the quiz card. CSV for Excel remains available under “More”.
Pedagogical analysis
With the confidence rating, participants indicate how sure they are after answering (1–5). You see not only the hit rate, but also confidently wrong answers — a useful tool for formative evaluation, focused debriefing and the results report (PDF) after the session ends.
Live Q&A as a moderation space
The Q&A wall is not a side chat. It is a dedicated live channel for facilitators and speakers: moderate submissions, spot collective priorities, surface controversial points and bring the key themes into the room via a weighted Q&A word cloud.

15 up · 3 down · best question

Q&A word cloud
Weighted by positive support and controversy.
Next step: a deterministic moderation compass, optionally complemented by asynchronous language-analysis signals and summaries grounded in the submitted questions.
Accessibility
For schools, universities and continuing education, accessibility is often a decisive criterion. arsnova.eu meets the Web Content Accessibility Guidelines (WCAG) 2.2 at Level AA — with keyboard use, screen-reader support, individually adjustable response time and accessibly structured PDF results reports.
You and your participants can use the core flows without a mouse. Visible focus marks and a skip link to content make navigation easier.
Status changes when joining a session, during voting and at phase changes are announced for screen readers so users can follow the flow.
For timed questions you choose standard time, tenfold response time or participation without a time limit. Reasonable adjustments can be applied directly in the live session.
The print-ready report is PDF/UA-1-validated and includes document title, language and tags — for follow-up and accessible sharing.

Differentiation
The focus is not only voting, but the full live flow: prepare, facilitate, make results visible and keep control of content and operations.
No separate product logic for “create” and “join”. Facilitators start without an account; participants enter the session via code or QR.
Alongside quizzes: matching, ordering, categorisation, numeric estimation questions, reading phase, Peer Instruction, Pulse Check, Q&A wall and weighted word cloud in one platform — not only slide polls.
Open source, runnable on your own infrastructure and with quiz content kept locally — plus conformance to WCAG 2.2 Level AA. Relevant for schools, universities and organisations with privacy and inclusion requirements.

FAQ
No. A session can be started without an account. Participants join via code or QR.
Quiz content stays on your device. For live sessions only the technically necessary session data is processed; when you run it yourself, operations stay in your own infrastructure.
Yes. The platform is open source and designed to run with Docker, PostgreSQL and Redis.
An optional follow-up after scored questions: participants rate on a scale of 1–5 how sure they are about their answer. Points stay unchanged; in the facilitator evaluation you see correctness × confidence and flag confidently wrong answers as a misconception signal. After the session ends, learning outcomes feed into debriefing and the results report (PDF).
Yes. After the session ends, the results report (PDF) is the primary format — including confidence rating, debriefing priorities and full question text. In the quiz collection you will find debriefing and PDF for the last run. Tabular CSV data is available under “More” for Excel.
It separates allowed inputs from the subject-matter tolerance band, shows no distribution during voting, and can evaluate a second round after discussion with statistics and round comparison.
Participants submit questions and weight them with upvotes and downvotes. Facilitators can pre-moderate, pin, archive or remove questions and sort the list by support, clear majority agreement or controversy.
It condenses visible questions into words and phrases and follows the active sort logic. So it shows not only frequent terms, but topic groups from supported, clearly high-scoring or controversial questions.
For live interaction in education and organisations: school, university, continuing education, training, workshop, event or meeting.
arsnova.eu conforms to WCAG 2.2 Level AA. Core flows are keyboard-operable, screen readers announce status changes, response time on timed questions is individually adjustable (standard time, tenfold response time or no time limit), and the accessibly structured results report is PDF/UA-1-validated.
