Many digital assessment tools show teachers whether students selected the correct answer. They reveal much less about how students reached it. Snorkl approaches formative assessment differently: students explain their thinking by speaking, drawing, annotating or writing, and the platform provides immediate AI-generated feedback.
In this Snorkl AI review, I examine how the platform works, the features that matter most for teaching, its potential classroom uses and the limitations teachers should consider before adopting it.
What Is Snorkl?
Snorkl is a web-based formative assessment and practice platform built around student explanations. Teachers create or select an activity, students demonstrate their thinking through one or more modes, and Snorkl analyses the response against criteria established by the teacher.
Depending on the activity, students can:
- Speak while drawing or annotating on a whiteboard
- Submit a whiteboard response without recording
- Record an audio explanation
- Write a short or extended response
- Upload or work with images, diagrams and other source materials
After submitting, students receive two or three pieces of AI-generated feedback. The feedback may identify something they did well, point to an area that needs clarification and invite them to extend their explanation. Students can then revise the same whiteboard or begin a fresh attempt.
This feedback-and-revision cycle is central to the platform. Snorkl is designed for practice and formative assessment, where students can act on feedback while they are still working through an idea.

Whiteboard Recording Activities
Whiteboard recording is the feature that most clearly distinguishes Snorkl from conventional quiz tools. Students draw, type, upload images or manipulate objects on a digital whiteboard while recording their voice and screen.
A mathematics teacher, for instance, could ask students to solve a problem while explaining why each step is appropriate. A science student could label a diagram and describe the relationship between its components. In social studies, students might annotate a primary source while explaining which evidence supports their interpretation.
This captures more than the final product. A teacher can hear the student’s explanation, observe the visual choices they made and examine how the response developed.
Recordings can be up to 20 minutes, although most classroom tasks will benefit from being much shorter. Students can receive time-stamped feedback linked to specific moments in the explanation.
Creating and Customizing Activities
Teachers can build an activity from scratch or copy one from the Snorkl Library. Existing activities remain editable, so teachers can change the prompt, instructions, whiteboard content and feedback criteria before assigning them.
When creating an activity, Snorkl can examine the question and draft:
- A description of the task
- The subject and approximate grade level
- An answer key or expected response
- Criteria for evaluating the explanation
Teachers should treat these as drafts. Snorkl itself advises educators to review and edit the generated criteria before assigning an activity. This step matters because the AI feedback will reflect whatever expectations appear in the criteria box. If the criteria are vague, overly demanding or misaligned with the lesson, the resulting feedback may be equally unsuitable.
The “Try as a Student” option is particularly useful here. Teachers can submit a sample response and see the feedback before sharing the activity with a class.
How Snorkl Scores Student Explanations
Snorkl can examine two related but distinct aspects of a response:
- Correctness: Whether the final answer, claim or conclusion meets the teacher’s criteria.
- Explanation score: How clearly and completely the student communicates their reasoning.
Explanation scores use a scale from zero to four:
- 0–1: Not yet — Reasoning is missing or too unclear to assess.
- 2: Fair — Some reasoning is present, but important details or connections are missing.
- 3: Strong — The explanation is mostly complete and meets most expectations.
- 4: Excellent — The explanation is thorough, clear and well structured.
This separation can reveal cases that a conventional quiz would miss. A student might reach the correct answer without showing meaningful reasoning. Another might use an appropriate process but make a small error in the final answer.
Teachers can hide scores from students or disable correctness scoring for open-ended work. That is worth considering when a task allows several defensible responses.
I would not treat these scores as independent evidence for high-stakes grading. They are more useful as signals that help teachers decide which responses to inspect, which misconceptions to address and which students may need additional support.
Teacher Insights and Class Monitoring
Once students begin submitting, teachers can view responses by activity and examine each student’s whiteboard, recording, written response, score and feedback.
Responses can be sorted by:
- Best attempt
- Latest attempt
- All attempts
- Correct
- Incorrect
- Incomplete
Teachers can also add their own comments. The Insights view helps identify patterns across a class, but those patterns still require interpretation. If several students receive low scores, the issue may lie in their understanding, the wording of the prompt or the criteria used to generate the feedback.
Activity Sets extend this workflow by connecting as many as ten activities. Teachers can determine whether students complete them in sequence or in any order. Progression can depend on a score, correctness, number of attempts or a combination of these conditions.
Classroom Uses for Snorkl AI
Mathematics
Ask students to solve a problem while explaining their choices. The whiteboard recording can capture calculations, diagrams and verbal reasoning together.
Science
Students can label a model, interpret a graph, predict an outcome or explain a scientific process. Teachers can focus the criteria on relationships between concepts instead of vocabulary alone.
Social studies
Students might annotate a historical source, compare accounts or construct a claim supported by evidence. The feedback criteria can ask them to identify the source and explain how the evidence supports their position.
Language learning
Audio-only activities can support pronunciation, oral explanation and language practice. Snorkl reports support for more than 65 languages, including translated directions, feedback and read-aloud tools. Teachers can view translated captions when a student responds in another language.
Writing
Writing activities can be used for short responses, argument development, reflection and revision. Teachers can specify what the response should contain and allow students to revise after receiving feedback.
Formative assessment
A short Snorkl response can serve as an exit ticket. Asking students to explain one concept in their own words may reveal more than asking them to choose an answer from a list.
Accessibility and Multilingual Support
Snorkl gives students several ways to express their understanding. A student who struggles with extended writing may be able to provide a clearer oral and visual explanation. Another may prefer a written response without recording.
The platform also includes translation and read-aloud support. Students can change their language settings, receive feedback in their selected language and switch back to English when needed. Teachers should still review the accuracy and appropriateness of translated feedback, especially when subject-specific language is involved.
These options can support more flexible participation, although flexibility should not obscure the construct being assessed. If an assignment is intended to evaluate formal writing, replacing writing with an oral explanation would change what the task measures.

Privacy and Student Data
Snorkl states that it removes personally identifiable student information before sending data to OpenAI and that the data is neither saved by third parties nor used to train future models. It also states that it does not sell student data, display advertising to students or allow behavioural tracking for targeted advertising.
Student work and recordings are private by default and are visible to the student, their teachers and relevant organisational administrators. Snorkl does not provide public profiles or a public “share to web” function.
Schools should still review Snorkl’s privacy policy and data-processing terms against their own provincial, state or district requirements. This is especially important because student voice recordings and written explanations may contain personal information.
Strengths of Snorkl
- It captures reasoning through speech, visuals and writing.
- Students can receive feedback while the task is still fresh.
- Feedback can lead directly into another attempt.
- Teachers can edit the criteria guiding the AI.
- Correctness and explanation quality can be considered separately.
- Existing activities can be copied and adapted.
- Multilingual and read-aloud tools support wider participation.
- Class insights can help teachers decide what to examine or reteach.

Limitations to Consider
- AI feedback can miss the mark. Snorkl provides a feedback-rating option partly because incorrect or unhelpful feedback can occur. Snorkl Help Center
- Useful feedback depends heavily on the quality of the teacher’s criteria.
- A numerical explanation score may simplify complex or open-ended reasoning.
- Voice recording requires functioning microphones, appropriate browser permissions and a classroom environment where students can speak.
- Reviewing recordings may still take considerable time when teachers need to examine responses closely.
- Multilingual feedback and translations require teacher judgement.
- The free plan limits activity creation.
- Institutional pricing is not publicly listed.
Is Snorkl Worth Using?
Snorkl is most useful when the learning goal involves explanation, reasoning or revision. It is less compelling when a teacher simply needs a quick factual quiz.
Its educational value lies in asking students to make their thinking visible. The AI feedback can help students revisit an explanation before the teacher has time to respond individually, while the dashboard can direct the teacher’s attention to patterns and potentially important responses.
I would use Snorkl as a formative layer around teacher judgement. The AI can provide an initial response, organize submissions and identify possible patterns. Teachers still need to define the learning goal, review the criteria, preview the feedback and decide what the student work actually demonstrates.
For classrooms that regularly ask students to explain how they know, Snorkl is certainly worth exploring.
