Certbar scales exam prep content in 85% less time.
Certbar, a competitive exam prep platform, needed 50 videos across more than eight subjects in 30 days. Its own curriculum team made them with vidBoard, with no editors, studios or freelancers.
Inside their videos
Frames recreated in vidBoard to show the kind of video described in this story.
Percentages in five minutes.
The shortcuts examiners expect you to know.
A price rises by 20%, then falls by 20%. What is the net change?
Three checks for every conclusion
- 1Is the middle term covered at least once?
- 2Do negative premises lead to a negative conclusion?
- 3Does the conclusion claim more than the premises?
A month of production, every month
- Each video took 4 to 6 hours to record, revise and edit.
- Coordinating presenters, reviewers and editors caused delays and missed deadlines.
- A single factual change meant booking the presenter again and redoing the production.
- Freelancers delivered inconsistent branding, voice quality and turnaround.
Scripts in, finished lessons out
The curriculum team writes the scripts and vidBoard does the rest: an AI avatar presents every lesson with automatic narration, so every video has the same on-brand presenter and voice. When a fact changes, they edit the script and render again instead of reshooting.
- STEP 01
Write the lesson script
The curriculum team drafts each script in-house, subject by subject.
- STEP 02
Present it with an AI avatar
One consistent presenter and voice across all 50 videos.
- STEP 03
Fix and re-render
A factual change is a script edit, not a reshoot.
“vidBoard turned a month-long slog into a one-week sprint.”
“Exams get tougher every year. Our content must get clearer and faster.”
