You teach a class of 30 students.
Each assignment needs personalized, thoughtful feedback that helps them actually improve.
You open the LMS, pull up the first submission, and start typing.
Twenty minutes later, you've covered one student.
Twenty-nine to go.
The feedback itself is hard to write well.
You draft a comment about thesis structure, rewrite it so it doesn't sound harsh, add an example, then realize the whole paragraph reads like a wall of text.
Tone is invisible in writing.
Constructive criticism lands as cold.
Encouragement sounds generic.
You second-guess every sentence because you know how students will read it.
Only 21% prefer text research shows students are 3x more likely to engage with video feedback than written comments
Tone gets lost constructive criticism reads as harsh, encouragement reads as generic, and intent gets misinterpreted
Weekend grading marathons personalized written feedback for 30 students means 10+ hours of typing per assignment cycle
Same mistakes next time when feedback goes unread, students repeat errors and you repeat yourself semester after semester
Teachers spend 5+ hours a week on feedback that students barely read. That is time and expertise wasted.

ngram turns your raw feedback recordings into professional, captioned videos that students engage with and learn from.
Pull up the student's assignment and record yourself reviewing it. Point at problem areas, highlight strengths, explain your reasoning out loud. ngram auto-cuts pauses, zooms in on the sections you reference, and adds captions so every student can follow along.
Speak directly to the student about their progress, strengths, and next steps. No screen share needed. ngram polishes the recording with clean cuts, branded styling, and accurate captions. Personal, professional, and done in minutes.
Either way, students hear your voice, see your intent, and actually use the feedback to improve.
Research shows video feedback reduces grading time by 50%. You say in 3 minutes what takes 20 minutes to type. Across 30 students, that is hours back in your week for lesson planning, office hours, or rest.
61% of students prefer video feedback versus 21% who prefer written. They watch the full video. They replay sections while revising. Your guidance reaches the students who need it most, not just the ones who read carefully.
Your voice carries warmth that text cannot. Students hear encouragement alongside critique. They see you as a person invested in their growth. That trust transforms how they receive difficult feedback and motivates them to act on it.
When students engage with feedback, they apply it. Studies show students who receive video feedback outperform those receiving written feedback. The revision quality goes up because the feedback actually landed.
Pull up the student's assignment and talk through it. Point out strengths, explain issues, suggest improvements. Pauses and filler words are fine. ngram works with however you naturally speak.
ngram auto-cuts dead air, zooms into the sections you referenced, and adds accurate captions. Review the storyboard, tweak anything, or approve as-is.
Export for Canvas, Blackboard, Google Classroom, or grab a direct link. Students click play right where they check their grades. Done.
Your pauses and filler words vanish automatically
You are recording feedback, not performing. Stumble over a word, pause to gather thoughts, say "um" while reading their work - ngram removes it all. Your 5-minute ramble becomes a focused 3-minute feedback video without you touching an editor.
