You are a professor, instructor, or course creator who explains complex concepts with clarity and patience.
Your students get it when you teach live.
But the moment you try to capture that same lesson on video, everything breaks down.
You open OBS, hit record, and start explaining.
Two minutes in you stumble on a term.
You restart.
The next take has dead air while you pull up the right tab.
Take three sounds great until you realize you forgot to share your screen.
By the fifth attempt, you have 45 minutes of raw footage for a five-minute concept.
5 hours per week Teachers spend creating instructional materials on top of their existing workload, according to national surveys
Expertise wasted on editing You have a PhD in your subject, not in Premiere Pro. Yet video production demands skills that have nothing to do with teaching
6-minute attention cliff Research on 6.9 million sessions shows student engagement drops sharply after 6 minutes, so pacing and polish are not optional
Outdated every semester Curriculum changes, textbook editions rotate, and last year's tutorials become liabilities you dread re-recording
Teachers spend an average of 5 extra hours per week creating instructional materials. Every hour lost to editing is an hour not spent on your students.

Quality consistency
ngram takes your raw teaching recordings, lecture captures, or screen walkthroughs and turns them into focused, captioned tutorial videos your students will actually finish.
Teach the way you would in a classroom. Stumbles, pauses, tangents are all fine. ngram removes dead air, tightens pacing, and adds smart zooms on diagrams, code, or UI elements. Your natural teaching voice stays intact while the rough edges disappear.
Paste in lecture notes, a syllabus section, or a slide deck URL. ngram generates the script and builds a complete tutorial with visuals, voiceover, and motion graphics. Turn documentation into instruction without recording anything.
Either way, your students get clear, professional tutorials and you get your evenings back.
When a tutorial takes 15 minutes instead of an entire afternoon, you stop rationing which topics "deserve" a video. Your course library fills out. Students get visual support for every concept, not just the ones you had time to record.
Stop restarting every time you say "um" or lose your train of thought. Record naturally. ngram edits out the stumbles, pauses, and false starts automatically. Your best explanation matters, not your best performance.
Tight pacing, smart zooms on key visuals, and accurate captions keep students engaged past the 6-minute attention cliff. Research shows short, well-produced videos boost exam performance by 9% over long-form lectures.
New textbook edition? Updated software interface? Re-record the affected section and swap it in under 5 minutes. Your tutorial library stays current semester after semester without starting from scratch.
Teach the concept as you would to a student sitting next to you. Stumbles, pauses, restarts are all fine. ngram works with raw, unpolished recordings.
ngram cuts dead air, adds smart zooms on diagrams and UI elements, generates accurate captions, and tightens pacing. Review the storyboard and adjust anything before rendering.
Export in any format for Canvas, Moodle, YouTube, or direct download. Update any section in under 5 minutes when your curriculum changes next semester.
Students never lose track of where you clicked
When you walk students through software, spreadsheets, or coding environments, cursor emphasis highlights every click and hover. Students follow along step-by-step instead of squinting at a tiny arrow on a busy screen. Especially valuable for technical tutorials where precision matters.
Learn moreEvery diagram and detail gets a close-up automatically
ngram detects when you interact with important screen elements and zooms in automatically. Formulas in spreadsheets, nodes in diagrams, buttons in software walkthroughs all get cinematic close-ups without you touching a keyframe. Students see every detail clearly on any device.
Learn moreYour 'ums' and retakes vanish automatically
Record your explanation naturally without worrying about false starts or dead air. ngram detects silences, filler words, and slow sections, then removes them to create tight, focused instruction. A rambling 20-minute recording becomes a crisp 8-minute tutorial your students will finish.
Learn moreAccessible tutorials for every student in your class
Accurate captions generated automatically make your tutorials accessible to students with hearing impairments, non-native speakers, and anyone studying in a library or noisy dorm. 85% of video is watched without sound. Captions are not a nice-to-have for education, they are essential.
Learn moreHighlight the exact step students need to remember
Add numbered step labels, annotations, and visual callouts that draw attention to critical moments in your tutorial. When you say "click here" students see exactly where "here" is. Perfect for multi-step processes where missing one click means getting lost.
