EXPLAINER VIDEOS

Make an AI explainer video.Presented by your mascot.

Bo explains why the sky is blue, in his own voice. Watch it, then make one with your mascot.

Make your mascot talkSee how it works

Make yours in four steps.

Set up your mascot in Masko, then let Claude Code make the video.

  1. Bo, the capybara mascot from the example
    1

    Create your mascot

    Upload your character, or create one in Masko Studio.

    Create a mascot
  2. 2

    Give it a voice

    Open your mascot, choose Voice, describe it, and keep one of three samples.

    Open my mascots
  3. 3

    Create an API key

    Claude uses it to make your mascot talk.

    Get an API key
  4. 4

    Ask Claude Code

    It writes the script, makes your mascot talk, and builds the video.

PASTE THIS INTO CLAUDE CODE

First create your mascot and its voice in Masko Studio. Then start Claude Code with your key: export MASKO_API_KEY=your_key, then claude, and replace the words in brackets.

Make a short explainer video about: [YOUR TOPIC]
Audience: [WHO IT IS FOR]. Use the correct terms, explained simply.

I already created my mascot [MASCOT NAME] and its voice in Masko Studio.
Use the Masko REST API at https://api.masko.ai/v1 with MASKO_API_KEY from my
environment, and never print the key. Read https://masko.ai/llms-full.txt first.

1. Research the topic from reliable sources and list each claim with its source.
2. Plan 8 to 10 steps, one idea each, from what people already know to the new
   idea, then a recap. Show me the plan and the script before anything paid.
3. Find my mascot with GET /v1/mascots. Generate one picture of it standing
   still, facing the viewer, arms relaxed, mouth closed. Every clip starts and
   ends on this pose.
4. Write each step as speech.script. Put a gesture in brackets before the words
   it goes with, acting out the idea, with a feeling after the last comma, for
   example: [stretches both arms far apart, happy] Red waves are long. Change
   gesture and feeling inside a line when the mood changes, like a whisper and
   then a jump. Feelings: excited, happy, proud, calm, curious, surprised, sad,
   whispering, laughing.
5. Before generating anything, check the price for free with a dry run and ask
   me to confirm. Then make one talking clip per step, so the video can pause
   between ideas, plus a short idle loop of the mascot breathing and blinking to
   play during those pauses.
6. Download each clip's transparent WebM, its MP3 and its transcript.
7. In the edit, speed up each talking clip and its voice together by about 10%,
   keeping the transparency and the voice's pitch, so the video stays lively.
8. Build the scenes in code as HTML animations rendered to video: the mascot on
   the left, a diagram on the right that builds over 1 to 3 seconds and then
   holds, one short key idea per step, a row of the steps at the top that
   highlights the current one, and captions timed to the sped-up clips. Pause
   about 2 seconds after each step and play the idle loop there. End on a card
   with my mascot's name. If I give you a music track, play it softly under the
   voice.
9. Export a 1920x1080 MP4, check every join, the captions and the sound, then
   open it for me.

Prefer clicking? Make each talking clip in Masko Studio, download the transparent videos, and ask Claude to build the scenes around them.

Steal Bo’s script.

Ten lines, one idea each. Copy the template for your topic.

  1. 01The question

    [waves hello with a big smile, excited] Why is the sky blue? [taps chin, thinking, curious] Let's find out, step by step.

  2. 02What people already see

    [points toward the right side of the frame, curious] First, sunlight. [shades eyes with one paw, curious] It looks white... [opens both arms wide, excited] but it's really a mix of all the colors of the rainbow!

  3. 03One new idea

    [points toward the right side of the frame, calm] Each color travels as a wave. [stretches both arms far apart, happy] Red waves are long. [holds both paws close together, excited] Blue waves are short!

  4. 04The setting

    [looks around in wonder, curious] Now, the air is full of tiny molecules... [points toward the right side of the frame, calm] mostly nitrogen and oxygen.

  5. 05The real word

    [points toward the right side of the frame, curious] When light hits them, [bounces up and down, excited] some of it bounces off in every direction! [nods, proud] That's called scattering.

  6. 06The key

    [leans in close, whispering] Here's the key... [jumps with excitement, excited] short blue waves scatter much more than long red ones!

  7. 07The answer

    [looks up at the sky, curious] So scattered blue light reaches your eyes from all over the sky. [opens both arms wide, happy] That's why it looks blue!

  8. 08A harder question

    [gasps with both paws on cheeks, surprised] But wait! Violet waves are even shorter. [scratches head, curious] Why isn't the sky purple? [points toward the right side of the frame, calm] Sunlight has less violet, and our eyes are less sensitive to it.

  9. 09A second case

    [points toward the right side of the frame, calm] At sunset, light travels through much more air to reach you. [clasps paws together dreamily, happy] Most of the blue is scattered away... so only reds and oranges are left.

  10. 10The recap

    [nods, proud] So remember: sunlight mixes every color, air scatters blue the most, [opens both arms wide, excited] and that blue fills the sky! [laughing] See you next time!

THE LITTLE DETAILS

A few questions.

we were hoping you’d ask.

How was this video made?

With Claude and the Masko API. Claude Code checked the facts and wrote the script, then called the Masko API to make Bo say each line in his own voice, one talking clip per step. It built the animated scenes in code, timed them to Bo’s transcripts, and rendered the video. We reviewed every step.

Can AI create an explainer video?

Yes, with a person checking it. AI helped write Bo’s script, Masko voiced and performed every line, and the scenes were built in code. We checked each fact against sources before publishing.

How much does it cost?

Talking costs 3 credits per second of video, and a free dry run shows the price first. This 99-second video used 245 credits, plus its voice samples.

See credits and pricing
Can I use my own mascot and voice?

Yes. Upload your character, then pick its voice from three samples. Adding a voice unlocks after $50 spent on Masko. Some Marketplace mascots already have one.

Read the talking guide
Does Masko make the whole video?

Masko makes the talking mascot: transparent video, voice and a transcript with the time of every word. You add the scenes in your editor, or let a coding agent build them.

Is the lip sync exact?

The mouth follows speech and silence, not each syllable, and a gesture can land up to a second after its word.
