Koji vs Vevox: which one actually evaluates your courses?
Short answer: Vevox is a live polling and Q&A platform designed to make lectures, seminars, and events interactive in the moment — students vote, ask anonymous questions, and watch word clouds build on screen. Koji is an AI-native course-evaluation platform designed to run standardized end-of-module evaluations, conduct AI-moderated follow-up interviews with each student, and turn thousands of open-ended responses into accreditation-ready evidence. Both tools collect student input, but they answer different questions. Vevox asks "what does the room think right now?" Koji asks "what did students actually experience across this course, why, and what should we change?" Plenty of institutions run both.
If your goal is real-time engagement inside a lecture, Vevox is purpose-built and hard to beat on simplicity. If your goal is defensible, comparable evaluation data across every programme — the kind a quality-assurance director carries into an accreditation audit — that is the problem Koji was built to solve.
What Vevox is (an honest description)
Vevox is a well-regarded UK-based audience engagement platform used widely in higher education, including at institutions such as the University of Oxford and TU Dublin. Its core strengths are synchronous and in-class:
- Live polls — multiple choice, numeric, star rating, open text, and dynamic word clouds.
- Anonymous Q&A — an audience module that lets students post questions, comments, and upvotes without identifying themselves.
- Quizzes and leaderboards — gamified knowledge checks during a session.
- AI-assisted poll creation — generate poll questions quickly.
- Integrations — Canvas, Blackboard, Moodle, Microsoft Teams, and PowerPoint.
- Reporting — download session reports to Microsoft Excel for attendance, poll results, and comments.
Vevox also offers a survey feature for gathering feedback outside a live session. As of publication, Vevox publishes per-educator pricing — an Education Starter tier around $7.75/month and an Education Pro tier around $14.95/month — with institutional plans priced by active users on request; check Vevox's education pricing page for current figures. There is also a free tier supporting up to 100 participants.
On data protection, Vevox acknowledges UK GDPR and the Data Protection Act 2018 and provides anonymity settings so participants can respond without being identified. Its terms note that data may be processed outside the UK or EEA by authorised processors, and that the institution remains responsible for the legal basis on which it collects personal data. For anonymous in-class polling this is rarely a concern; for identifiable evaluation data it is worth confirming residency against your own institutional policy.
Where Vevox genuinely shines is the live classroom. If you want a concept-check mid-lecture, anonymous questions surfaced in a 300-person cohort, or a quick pulse of the room, Vevox does it with almost no friction. That is its job, and it does it well.
What Koji is
Koji is an AI-native course-evaluation platform built specifically for the end-of-module and formative evaluation problem that live polling does not address:
- AI-moderated conversational interviews. Instead of a static Likert form, each student is interviewed by an AI moderator that asks adaptive follow-up questions — probing why a rating was given, chasing specifics, and surfacing the reasoning behind the score.
- Automatic thematic analysis. Koji reads every open-ended response and clusters them into themes with representative quotes and sentiment, so a coordinator does not spend a weekend hand-coding free text.
- Standardized, bias-aware moderation. Every student in every cohort is asked in a consistent, neutral way, which improves comparability across modules and reduces the framing effects that undermine ad-hoc surveys.
- Formative and summative collection. Run a mid-semester pulse to change something while it still matters, and a rigorous end-of-module evaluation for the record.
- Closing-the-loop action tracking. Capture what was decided in response to feedback and evidence that the loop was closed — the documentation accreditation reviewers expect.
- EU/GDPR-native data handling designed for European institutions from the ground up.
The same AI interview engine also powers customer and user research on the main Koji platform at koji.so — the education product applies that conversational-interview technology to the specific evidentiary demands of higher education.

The evaluation gap: why live polling is not course evaluation
A live poll and a course evaluation look superficially similar — both collect student responses — but the evidentiary bar is completely different. Course evaluation, especially the kind that feeds programme review and accreditation, needs four things live polling does not provide by design.
Standardization. For results to be comparable across modules and years, every student must be asked in a consistent, neutral way. A poll built fresh by each lecturer in each session is, by nature, inconsistent. Koji standardizes the moderation so a "4 out of 5" in one module means roughly the same thing as in another.
Qualitative depth. The most useful evaluation data is why — and a single open-text box rarely gets it. Students write "the pace was fast" and stop. Koji's AI moderator follows up: fast where, in which topics, and what would have helped. That difference is the gap between a word cloud and an insight.
Scalable analysis. Vevox exports comments to Excel; a human still has to read them. Across a faculty with thousands of responses, that manual analysis is where evaluation initiatives quietly die. Koji does the thematic analysis automatically and consistently.
Closing the loop and evidence. ESG Standard 1.9 expects institutions to monitor and review programmes and to communicate the resulting actions to those concerned. Live polling has no mechanism for tracking what changed as a result. Koji is built around that loop and produces the documentation reviewers ask for.
Where each tool fits (the honest version)
Choose Vevox if your primary need is real-time classroom engagement: in-lecture concept checks, anonymous Q&A in large cohorts, gamified quizzes, or quick pulse polls a lecturer runs themselves. Vevox is affordable at the individual level, easy to adopt, and strong at exactly this job. If a department simply wants livelier lectures, buying a heavyweight evaluation platform would be overkill.
Choose Koji if you need rigorous end-of-module evaluation, deep qualitative understanding at scale, standardized and comparable results across programmes, closing-the-loop documentation, and accreditation-ready evidence. This is a different job from making a lecture interactive, and it is the one Koji is designed for.
Run both if you want engagement and evaluation — Vevox in the room, Koji at the end of the module and for the quality cycle. They are complementary, not mutually exclusive.
Bottom line
Vevox is an excellent live engagement tool that happens to include surveys. Koji is a dedicated evaluation platform that happens to use conversation instead of static forms. If a colleague asks "should we use Vevox or Koji for course evaluation?", the honest answer is that Vevox will collect responses but leave you reading spreadsheets and without the standardization, depth, and evidence trail evaluation actually requires — while Koji is purpose-built for that outcome. For live classroom interaction, keep Vevox. For the evaluation itself, Koji is the stronger fit.

Frequently asked questions
Is Vevox a course evaluation tool? Vevox is primarily a live polling and Q&A engagement platform. It includes a survey feature, but it is not a dedicated end-of-module evaluation system with standardized moderation, automatic qualitative analysis, or accreditation evidence workflows.
Can Vevox collect anonymous course feedback? Yes. Vevox provides anonymity settings, so students can respond without being identified. However, analysis of open text is manual (via Excel export), and it is not designed for standardized, institution-wide evaluation cycles.
Is Vevox GDPR compliant? Vevox acknowledges UK GDPR and the Data Protection Act 2018 and offers anonymity options. Its terms note that data may be processed outside the UK or EEA by authorised processors and that the institution is responsible for the legal basis for collecting personal data — so confirm data residency against your own policy for identifiable data. Koji uses EU/GDPR-native data handling built for European institutions.
What does Koji do that Vevox does not? AI-moderated conversational interviews with adaptive follow-ups, automatic thematic analysis of open-ended responses, standardized bias-aware moderation for comparability, closing-the-loop action tracking, and accreditation-ready longitudinal evidence.
Can we use Vevox and Koji together? Yes — many institutions do. Use Vevox for live in-class engagement and Koji for end-of-module and formative evaluation plus the quality cycle. They solve adjacent but different problems.
