Most guides for downloading YouTube transcripts assume you are at a desk with a browser open. That is fair, but incomplete. Plenty of people discover content on their phone, want to save it for reading later, and would rather not wait until they are back at a computer.

YTCaptions works on mobile. To use it from your phone or tablet, paste the video URL and download the transcript. Here is what you can do with the file once you have it.

The Short Version

Open YTCaptions in your mobile browser, paste the YouTube video URL, pick your format, and download. The interface is responsive and does not require any app installation.

That is the whole workflow in two sentences. There are a few things worth knowing about what happens next, especially if you want to read and annotate the transcript on your device.

Step by Step

Open your browser and go to the YTCaptions page. Paste the URL of the video you want into the input field. You can copy a link directly from the YouTube app, the YouTube website, or any other app that shares video links.

Select Markdown if you plan to read the transcript yourself. Select JSON if you are sending it somewhere else, such as a note-taking app with automation features or a script you run.

Tap Transcribe. The result appears on the same page, ready to copy or download. On most phones, tapping the download button saves the file to your downloads folder. From there you can open it in any text editor, note-taking app, or reader app.

What to Do With the Transcript on Your Phone

Copy the text and paste it into your notes app. Most phones handle plain text copying without any formatting issues. Markdown formatting, when present, pastes cleanly into apps that support it, such as Obsidian, Notion, or Bear. If you paste into a plain text app, the Markdown characters remain visible but the file is still readable.

If you want timestamps, the Markdown format includes them as [MM:SS] markers. You can search for a specific time in your notes app and jump back to that point in the video if you need to verify something against the original.

For quick study sessions, copy a section of the transcript, paste it into a flashcard app, and create a simple Q&A pair. This takes about two minutes and turns passive video watching into active review material.

What About the YouTube App Itself?

YouTube has a built-in transcript feature that you can access by tapping the three dots below a video and selecting "Show transcript." This gives you a scrolling text view of the video captions.

The limitation is that you cannot easily export this text. You can select it and copy it, but the formatting is minimal and timestamps are not included. The result is plain text that is harder to navigate than a structured transcript.

YTCaptions, by contrast, produces a structured document with metadata, timestamps, and clean formatting that travels with the file wherever you send it.

Offline Access

If you download the Markdown file to your phone, it is available offline. This matters on a flight, a commute with poor reception, or anywhere you do not want to use data on a video you have already watched.

The transcript is typically under 50KB for a 20-minute video, so storage is not a concern. You can keep dozens of transcripts in a folder and read them whenever you have a few minutes free.

A Note on Accuracy

The transcript accuracy on mobile is the same as on desktop. YouTube serves the same caption track regardless of device. If the video has manually uploaded captions, those are what you will receive. If it only has auto-generated captions, the text will reflect the quality of YouTube's speech recognition for that video.
