WHAT CHANGES

Two tech briefs, with and without a face.

HOW IT WORKS

Three steps from reference to result.

Open the Studio

  1. Bring a tech reference

    Paste a public YouTube link or choose an image with the visual role your video needs.

  2. Name the real result

    Add the tool, build, review, comparison, workflow, or lesson the video actually delivers.

  3. Add your photo or keep it product-led

    Use your photo for a creator-led video, or let the device, screen, or workflow lead.

BUILD THE BRIEF

Give the idea a clear direction.

Choose one technical subject

Let one device, app, workflow, result, or before-and-after comparison carry the frame.

Show the outcome, not every control

A finished result or one important screen region reads faster than a complete interface full of tiny labels.

Check exact product details

Generated logos, interface text, device details, and screenshots can drift. Use a real attached asset or an editor when accuracy is essential.

QUESTIONS

What to know before you start.

The format can fit software tutorials, AI tools, device reviews, coding builds, comparisons, automations, and workflow videos.

Not reliably. Generated interfaces, logos, labels, and product details can vary. Attach a clear supporting image where appropriate and review the result, or use an editor for exact placement.

Yes. Skip the personal photo and make the product, result, workflow, or comparison the main subject.

Yes. Choose 9:16 or both so the tech brief is recomposed for a tall frame.
