01 · THE CHALLENGE

More time producing than teaching

  • Recording, editing and voiceovers took 3 to 5 hours for every video.
  • Freelancers and voice artists had to be paid for each one.
  • He could publish only 1 or 2 videos a week, which slowed the channel down.
  • He handled every task, vendor and revision himself.
02 · WHAT THEY DID

Lessons without the production work

Bharat now makes avatar-led lessons with automatic AI voiceovers, edits them in real time when something needs to change, and publishes straight from vidBoard to YouTube.

  1. STEP 01

    Avatar-led lessons

    No recording sessions or voice artist bookings.

  2. STEP 02

    Real-time edits

    Fix a lesson and republish without re-recording.

  3. STEP 03

    Publish to YouTube

    Lessons go straight from vidBoard to the channel.

“I'd rather spend time teaching than wrestling with editors and voice artists.”

“vidBoard lets me post five polished lessons a week, solo, stress-free.”
