After every submission, Viva holds a short voice conversation with each student about their own work. Your school gets verifiable evidence of learning, spoken in the student's own words.
Schools: pilot this term. Instructors and students can start free — no payment info needed.
The student owns the core argument and defended her data choices under follow-up questions. Explanations matched the submission throughout.
ID V-8F3A“You chose a t-test in section 3. Why that over ANOVA for this data?”
Step into a student's shoes for a moment, then see the report you get back.
A scripted taste. On the live product, Viva adapts with AI, in the student's language, after every submission.
Every interview becomes a report tied to what the student actually submitted: what they understood, where they were shaky, and proof it was really them. Watch it read itself.
Instructors feel it every day. The work comes in polished, and they can no longer tell what the student actually knows. Detectors false-flag honest students and miss lightly-edited AI. Banning it is unenforceable. Rewriting every assignment is an arms race you lose. So the grade goes out, and no one, instructor or student, is sure learning happened.
of students already use AI in their studies. The question was never whether they use it. It's whether anyone can still tell what they learned.
false-positive rates for AI detectors on non-native English writing. Guessing from text punishes honest students and proves nothing.
Every school feels this. Almost none can name it precisely, or respond in a way that actually works. Naming it is where the fix begins.
Essays, lab reports, code, slides, posters, spreadsheets. Nothing changes about how you assign.
A 5 to 10 minute voice conversation about their work, in their language. Adaptive follow-ups probe the reasoning behind every claim. Identity is confirmed by voiceprint.
A clear verdict with evidence: understanding and authenticity scores, quotes tied to the document, integrity signals, and a second opinion from independent AIs. You stay the judge.
Could not explain the thesis he submitted. Vocabulary in conversation didn’t match the essay’s. Independent AIs corroborate. Suggested: give a second chance →
Verification rates, flags, and follow-ups in one view. Department heads know where learning is proven, and where to look closer, without chasing spreadsheets.
| Assignment | Verified | Status |
|---|---|---|
Research essay: oral defense Submitted work · 10 min | 79% | Open |
Close reading: argument & evidence Submitted work · 8 min | 100% | 2 flagged |
Rhetorical analysis defense Submitted work · adaptive | 96% | Closed |
Every verdict is backed by layered, inspectable signals. Schools adopt Viva because the report holds up when a parent asks why.
A short enrolled voiceprint confirms the same student is speaking in every session. Consent-based, biometric-grade.
AIs from different providers re-score flagged interviews blind. Agreement becomes a trust badge on the report.
Generated diagrams test real understanding on the spot. Answers read from a second screen don’t hold up to them.
Report claims link to highlighted passages in the actual submission, PDFs, docs, even scanned posters via OCR.
Optional camera and tab-focus checks for high-stakes exams. Off by default, instructor-controlled per assignment.
Viva never makes the final call. It surfaces evidence, suggests second chances, and records your decision.
Single sign-on launch and grade passback through LTI 1.3. Rosters sync nightly from your SIS. Students never manage another account.
Encrypted in transit and at rest. Recordings auto-delete on a 30-day clock. Voiceprints are consent-based and never used for anything but identity. A signed DPA for every school.
Strict data-residency requirements? Viva Private runs single-tenant inside your institution's own cloud.

Every verified conversation can issue a Viva Card: a tamper-evident credential a student attaches to an application, portfolio, or transcript. Anyone can verify it. Only the school can revoke it.
VIVA·8F3A…C1D9Viva doesn’t guess from text like detectors do. It asks the student to explain, defend, and extend their own submission out loud, with adaptive follow-ups no script can prepare someone for. Inconsistency shows up as evidence, not a probability score.
Conversations run in the student’s language (English and Korean today, more coming), grading never punishes accent or hesitation, and instructors can set equality accommodations, including a human-run 1:1 alternative for any student.
About zero per student. Interviews run themselves after submission; you review a one-screen report, and most classes need a closer look at only 2 to 3 flagged results. Grades pass back to your LMS automatically.
Layered safeguards make live coaching impractical: voiceprint identity, natural-pace conversation, generated visual probes, optional focus and camera signals, and cross-checking by independent AI models.
Instructors and students can start free. Schools license per student per year, with pilot pricing that includes every premium feature. Ask us for the one-page pricing sheet.
Pilot in one department this term. Set up takes an afternoon, not a semester.
