Build a Chrome extension for presenting webinars
A Replit forum user built a Chrome extension so they could keep notes in view while presenting webinars, and published it to the Chrome Web Store.
- What They Did
- The poster wanted to stop glancing down at notes during webinars, so they built a floating teleprompter overlay for browser-based video meetings. They started in Replit with a rough first version and debugged it until it stopped crashing. Then they pushed it to GitHub and moved it into a Claude project. They fixed issues the Chrome Web Store reviewers raised, then published.
- How It Went
- The extension was published on the Chrome Web Store and the author finds it useful. A commenter reported it doesn't work on Mac, because Alt+T opens a new tab. The author develops on Windows.
- Worth Knowing
- The author says the build was roughly 80-85% Replit, with Claude and ChatGPT used for refinement, and the process was repeated build-break-fix cycles rather than one clean prompt.
Try it yourself with Replit Agent
Build me a Chrome extension that shows my [speaker notes / talking points] in a small always-visible panel while I present [webinars or screen-share talks]. I should be able to paste in and edit notes, and resize or move the panel. You're done when I can load the extension locally in Chrome and see my notes on a test page, then walk me through the steps to publish it to the Chrome Web Store without submitting anything yet.
