Feedback platform
Photograph student work, annotate with pins and drawing, and send rich feedback in minutes. Students open a simple code on their phone — no login, no friction.
Workflow
Ekko keeps the loop short: capture work, annotate on the photo, publish once, and students receive feedback on the device they already carry.
Photograph a page, exercise, or project from your tablet. Batch capture flows through an entire assessment in one sitting.
Draw corrections, place pins with voice or video, and attach rubrics. Everything stays anchored to the student's actual production.
Students receive a push notification. You choose whether self-grading is required before they see your annotations.
No account — just a personal code. Feedback loads offline and stays available for review before the next attempt.
Impact
Ekko shortens the loop on both sides: teachers annotate on the photo instead of writing long comments in a gradebook, and students open their own assessment with your pins — precise, timely, and ready on their phone.
Traditional
With Ekko
Photograph work once, drop voice pins instead of typing paragraphs, batch a full class, and let AI draft reports — feedback that used to take an evening fits between lessons.
Students get a push when you publish — minutes or hours, not days or weeks. The correction lands while the exercise is still fresh, and richer pins make it easier to act on.
Students don't get a lone grade or a separate comment thread — they open the actual page you photographed, with drawings and pins on their real work.
Each pin sits on the exact spot on the page — voice, video, or text anchored to the mistake or success. No vague "see paragraph three"; they tap once and see it.
Student app
Ekko is an installable PWA on the student's phone — no account, no password. They enter a personal code once, get push notifications when you publish, and read annotated work offline whenever they need it.

Each student gets a short code. They open it in the browser or install Ekko on their home screen — no email signup or school SSO.
Published feedback is cached on the device. Students reopen annotated work, re-listen to voice pins, and review before the next attempt — even without Wi‑Fi.
When you publish, students get a notification on their phone. New feedback appears in their feed with a clear "new" badge.
Three tabs: latest feedback, course tasks, and a radar view of objectives. Tasks sent from the AI report appear in the Tasks tab with the same checklist layout.
Annotate
Capture a photo from your tablet, sketch corrections with the pen, and place markers exactly where they matter. Pins stay anchored when students zoom on any screen size.
Rich pins
Each pin carries the medium that fits: record a quick voice note, attach a reference image, paste a video link, or write a short comment. Students tap once to listen or watch.
Record feedback on the spot. Students tap once to listen — with optional transcription to read what you said.
Example: "Check the denominator here" on the fraction line.
Paste a YouTube or other video link. Students watch in place without leaving their feedback.
Example: "How to simplify fractions" linked beside the exercise.
Short written notes anchored to the exact place on the page — no vague "see paragraph three".
Example: "Find a common denominator first" next to the sum.
Share an article, glossary entry, or reference URL tied to a specific spot on the work.
Example: britannica.com/topic/fraction anchored to the mistake.
Attach a photo, diagram, or model example right where the student needs visual guidance.
Example: a worked solution photo placed on the blank answer.
Publish
Hit publish and students get a push notification on their device. They open the app offline-first — cached feedback loads even without a connection.

Rubrics
Design rubrics as level columns × criterion rows with descriptors in every cell. Save templates, attach them to objectives, copy to assessments, and optionally require self-grading against the same grid before students unlock your feedback.

Self-grading
Optionally ask students to self-grade against the rubric before your pins and annotations unlock. They engage with criteria first; you see where their judgment aligns with yours — or where a gap needs a conversation.
Feedback unlocked
After submitting a self-grade, your teacher's pins and annotations appear on the work.

Metacognition
Self-grading is not a shortcut for teachers — it is a metacognitive pause. When students judge their own work against clear criteria before seeing your annotations, they activate monitoring systems the brain uses to detect gaps and update mental models.
Selecting a rubric level forces students to ask "Did I actually meet this criterion?" — the same question expert learners ask spontaneously.
Flavell's metacognitive framework: monitoring accuracy is a learnable skill, and structured prompts accelerate its development.
When self-assessment and teacher assessment diverge, attention goes to the discrepancy — often the highest-value moment for dialogue.
Sadler (1989) and subsequent work on evaluative judgment: understanding quality requires comparing one's own work to a standard — repeatedly.
Producing a judgment before receiving yours engages retrieval and inference — a desirable difficulty that deepens encoding of your later feedback.
The generation effect (Bjork): actively producing an answer — even an imperfect one — improves learning from subsequent corrective feedback.
Explicit criteria split a vague "How did I do?" into scorable dimensions — lowering the working-memory cost of self-evaluation.
Structured rubrics channel attention toward features of quality instead of global, often inaccurate, impressions.
In Ekko, self-grading can gate access to your pins: students complete the rubric, submit, then unlock your visual feedback — so reflection precedes reception by design.
AI transcription
Record feedback on the canvas, then transcribe with one tap. Whisper turns audio into text you can edit, store alongside the pin, and reuse in reports — students can read what you said without replaying every clip.

Good use of the scale here — next time label the capital cities directly on the map so the reader doesn't have to guess.

AI assessment report
For each assessment, Ekko gathers transcribed voice notes and text pins across all students. AI reads the full comment set and drafts a structured report — summary, strengths, gaps, and suggested next steps — so you see patterns without rereading every pin.
Comments on this assessment
Scale is mostly correct; legend symbols need clearer labels.
Strong spatial awareness on continental boundaries.
Check the orientation — north arrow is missing on page two.
Assessment report
Geography · Map skills · 24 students
Summary
Most students handle scale well; recurring gaps are legend labeling and compass orientation across multi-page submissions.
Strengths
Continental placement and use of colour to distinguish regions appear consistently in comments.
Next steps
Plan a short mini-lesson on legend conventions; ask for a north arrow on every map before the next capture.
Next steps
AI reads each student's pins and drafts a report in their language — what went well, what to review, and concrete actions for their next attempt. Send any checklist item to their Tasks tab with one tap and track when they complete it.

Learning science
Decades of research in cognitive psychology and education converge on a few principles: feedback is most powerful when it is timely, specific, multimodal, and low-threat. Ekko is designed around those constraints — not generic comments in a gradebook cell.
When feedback is pinned on the page where the error occurred, the brain links the correction to a visual location — not to a separate comment thread.
Cognitive load theory (Sweller): integrating feedback with the artifact avoids splitting attention between the work and a distant text box.
A short voice note plus a mark on the diagram activates both verbal and visual processing — especially helpful for younger learners and complex tasks.
Dual coding (Paivio): information encoded through two channels is more likely to be remembered and applied on the next attempt.
Feedback delivered soon after production lands while the task context is still active in working memory — before misconceptions consolidate.
Meta-analyses on formative feedback (Hattie & Timperley; Rosenshine) consistently rank timing and task-level specificity among the strongest levers.
Reading feedback alone on a phone — rather than in front of the class — reduces social comparison and the stress response that blocks deep processing.
Acute stress impairs prefrontal circuits involved in error correction; calmer delivery supports the mindset feedback is meant to create.
Pins answer "what exactly should I change here?" — not "good job" or "see me after class." Actionable cues drive revision behavior.
Feedback at the process and self-regulation levels (Hattie & Timperley) outperforms praise or grades alone for learning gains.
Students can reopen annotated work on their phone, re-listen to voice pins, and compare before/after — retrieval practice embedded in the feedback loop.
The testing effect: actively revisiting material with meaningful cues strengthens long-term retention more than passive re-reading.
Summaries draw on established learning-science literature. Effects vary by context, age group, and task — Ekko supports the conditions research identifies as favorable; it does not replace professional judgment.
