Translating PowerPoint decks when Copilot is the only AI you're allowed to use

On many corporate laptops you have no admin rights and can't install anything, and Microsoft Copilot is the only AI tool available. Translating a 40-slide deck in that setup means a lot of copy-paste and a lot of rebuilding the layout afterwards.

So I built a small tool for it: PPTX Copilot Translator.

🔹 It's a single PowerShell script. No install, no admin rights, and it runs locally in your browser. 🔹 It pulls the text out of the slides, including tables and nested groups, and splits it into prompts that are the right size for Copilot. 🔹 You paste Copilot's answer back, and it repairs common copy-paste damage like broken accents and escaped characters. 🔹 It writes the translated text back into the original .pptx, so the layout and formatting stay as they were.

The copy-paste step with Copilot stays manual on purpose. Your data only goes to the AI your company has already approved.

I built it with Claude Code and OpenAI Codex. It's open source under the MIT license: 👉 https://gitlab.com/id.lorincz.adam/pptx-copilot-translator
