Support | Lingo Gapfy

Getting Started

How do I start an exercise?: Open a YouTube watch page, make sure the video has subtitles, click the Lingo Gapfy icon in your toolbar, and click “Start Exercise.”
How do I pin Lingo Gapfy to the toolbar?: Click the puzzle icon in the top-right corner of Chrome, then pin Lingo Gapfy so it stays visible in your toolbar.
Do I need an account?: No. You can install the extension and start practicing without creating an account.
Where should I use Lingo Gapfy?: For now, use it on desktop Chrome on a YouTube watch page.

Why does the popup say “Open a YouTube video first”?: The popup only becomes ready on a YouTube watch page. Open a regular YouTube video page first, then open Lingo Gapfy again.
Why does the popup say “Preparing YouTube”?: Lingo Gapfy is still waiting for the YouTube player to finish loading. Give the video a moment, then try again.
Why can’t I see “Start Exercise”?: First open a YouTube watch page. If the popup is still loading, wait until YouTube is ready. Once the page is ready, the popup will show the start action.
Why isn’t the exercise showing on my video?: Make sure the video is on YouTube, the page is fully loaded, and subtitles are available for that video. Lingo Gapfy needs subtitle data to create the exercise.

Do subtitles need to be turned on?: Yes. If subtitles are off, Lingo Gapfy will ask you to open the YouTube player settings, turn on “Subtitles/CC,” and choose a subtitle language.
Does Lingo Gapfy work on videos without subtitles?: No. Lingo Gapfy turns subtitle lines into exercises, so it needs subtitle data from the video.
Does it work outside YouTube?: No. The current version is built for YouTube watch pages.
Does it work on every YouTube page?: Use it on normal YouTube watch pages. Other YouTube surfaces are not the main supported flow.

What does “Replay” do?: Replay plays the current subtitle line again so you can hear the phrase before filling the gaps.
Why are some subtitle lines skipped?: Some subtitle lines may not produce usable gaps. Depending on your settings, Lingo Gapfy can skip subtitle lines without gaps automatically.
Why does the video resume automatically?: Lingo Gapfy can resume the video automatically after you complete all gaps. You can change that behavior in the popup settings.
Can I change exercise behavior?: Yes. The popup includes settings for auto-resume and for skipping subtitles without gaps.

Why doesn’t translation appear?: Translation controls only appear when the current browser and language pair support translation. If the control does not appear, that pair is not available right now.
Why do I see translation on some videos but not others?: Translation depends on the subtitle language, your interface language, and browser support for that pair. Some combinations are available, and some are not.
Can I force translation to appear?: No. If the browser reports that the current language pair is unavailable, Lingo Gapfy hides the translation controls.

Does Lingo Gapfy work on mobile?: No. The current support flow is desktop Chrome.
Does it work in browsers other than Chrome?: Install and use Lingo Gapfy through the Chrome Web Store flow. If you want the supported setup today, use desktop Chrome.
Does the extension show ads or require payment to start practicing?: No. The current product messaging is free to use and has no ads inside the extension.
