Say what needs explaining. Get the video.

Explainer Studio writes the scenes, narrates them and fires every animation on the word it belongs to. It runs on your own machine and renders the same frames every time.

scenes/gateway.tsx · narration and the steps anchored to it

A request from the browser hits the gateway, which checks the token before it reaches any service.

  • gateway −150ms

    Draw the gateway

  • token −150ms

    Highlight the token check

  • service −150ms

    Fan out to the services

Drag a marker and only that scene re-renders. The narration is never spoken twice for the same words.

From a brief to a finished file

  1. 01

    Write the brief

    Describe what you want explained, and point the agent at a folder it may read: a repository, a docs directory, a design note. It writes the scenes as real source files.

  2. 02

    Watch it work

    Every tool call the agent makes is named in plain language as it happens, with the model, the credentials in use and the cost so far in the header.

  3. 03

    Tune the timing

    The timeline shows the waveform and every word of the narration. Drag a step onto a word, nudge it by 100 milliseconds, undo if you were wrong.

  4. 04

    Export

    One button runs narration, rendering, joining and the checks, then plays the result in the window. Only what changed is rendered again.

Everything is a file

A project is a directory. The agent, the editor and git all see the same thing, so a video review is a diff and a mistake is a revert. Nothing is locked in a database you cannot read.

Narration audio, rendered segments and the finished video sit next to the scenes that produced them.
