Explainer videos you can check line by line.每一句都查得到出處的講解影片。

SheldonTek is a three-person company in Hong Kong, founded in December 2022. We build software for making short explainer videos, and we use it to make our own.

Every quotation in our videos is checked against a saved copy of its source before the episode can move on. Scripts are AI-assisted and reviewed by us. Narration is synthetic, and we say so in every description.

SheldonTek 是一家香港公司，2022 年 12 月成立，現在有三個人。我們寫製作講解短片的軟件，也用它做自己的影片。

影片裏每一句引文，都要先跟存檔的原文逐字對過，才能進入下一步。稿子由 AI 輔助起草，再由我們審核。配音是合成語音，每條影片簡介都會寫明。

NarratorForge is our production pipeline. It goes from saved sources to script, narration, code-drawn animation, subtitles and automated quality checks, and it renders both a landscape and a vertical version from the same scene code.

Laws of Wealth is the channel we make with it: short histories of merchants, markets and economic ideas, from Fan Li and the Shanxi banks to the Medici and Rockefeller. It runs in English and Chinese. It covers history and principles only, never investment advice.

NarratorForge 是我們的製作流程：從存檔史料開始，經過稿子、配音、程式繪製的動畫、字幕，到自動質檢，用同一套場景程式同時輸出橫屏和豎屏兩個版本。

「財富的規律」（Laws of Wealth）是用它做的頻道，用短片講商人、市場和經濟思想的歷史，從范蠡、山西票號講到美第奇和洛克菲勒，有英文和中文兩個版本。內容只講歷史和原理，不構成投資建議。

We make short explainer videos to order: a product, a process, a piece of history or a concept. You send the material, and we write a sourced script, add synthetic narration and animated visuals, and deliver landscape and vertical files. You review the script before anything is rendered.

Write to us with what you need and roughly when. We will reply with a quote.
