Video discussions
to make learning
engaging, fun, & empowering.
★★★★★ 4.8/5 start
The loop your class loved.
When Microsoft shut down Flipgrid, districts lost the easiest way to hear every student out loud. VidTalk brings it back — and now every reply grades itself against your rubric.
01
Post a question
Type any prompt — a book recommendation, a lab reflection, an exit ticket. Set a response length and a rubric.
02
Students reply on video
Kids record from any device in one take. No accounts to manage, no software to install.
03
Classmates reply to classmates
Students respond to each other's videos, turning a solo assignment into real discussion.
04
Coral grades every reply
Each response is scored to your rubric and returned with specific feedback — automatically..
The engagement, without the grading backlog.
Every video reply gets transcribed, scored to your existing rubric, and sent back with specific, encouraging feedback before your next class starts.
✓ Uses the rubric you already have, nothing new to build
✓ Feedback is specific, not just a number
✓ Class-wide misconceptions surface automatically, so you know what to reteach
🧑🏫
For teachers
Run the same discussions, keep none of the grading.
✓ Post a prompt once — reuse it across periods or years.
✓ See rubric scores and feedback the moment students submit.
✓ Spot class-wide misconceptions before the next lesson.
✓ Works with the LMS and SSO your district already runs
🧑🎓
For students
No stage fear. Just talk to the camera.
✓ Record in one take, right from a phone or Chromebook.
✓ Answer prompts in their own time, at their own pace.
✓ Reply to classmates instead of just an empty comment box.
✓ Get specific feedback back in minutes, not next week.

Know a teacher who misses Flipgrid?
Send them the tool, not the eulogy.
One share is usually all it takes — most teachers forward this to two or three colleagues before they've even finished setup.
Before you ask, we did.
-
Yes. VidTalk is COPPA and FERPA aligned — student videos and data stay within your district's agreement and are never used to train external models.
-
No. Students join with a class link or code from any device — no email or app download required.
-
Nothing beyond a standard SSO connection if you use one. VidTalk runs in the browser and works behind most district content filters out of the box.
-
You bring (or build) a rubric; Coral transcribes each response and scores it against your criteria, returning feedback you can edit or approve before it reaches students.
