Get YouTube Transcripts Without a Chrome Extension

Every Chrome extension that extracts YouTube transcripts has the same vulnerability: it reads text directly from YouTube's page DOM, and YouTube changes that DOM regularly. Extensions that work today can silently break tomorrow. The Obsidian Web Clipper's YouTube transcript selector broke twice in the first quarter of 2026 when YouTube updated its interface (Obsidian Forum, thread 111550). Glasp's YouTube Summary extension has gone through multiple forced updates after similar breakages.

INDXR.AI doesn't use a browser extension and doesn't read YouTube's frontend HTML. It retrieves transcripts via YouTube's internal API and, when captions aren't available, transcribes directly from the audio. This approach doesn't break when YouTube redesigns its UI.

Why Extensions Break

Browser extensions that extract YouTube transcripts work by injecting JavaScript into the YouTube page and reading elements from the DOM — specific CSS selectors, element IDs, or text nodes that contain the transcript data. This works until YouTube changes the layout.

YouTube updated its video page structure in February 2026, changing how the transcript panel was rendered. Within days, multiple widely-used extensions and tools that relied on scraping those elements stopped working. For tools that specifically used engagement-panel-searchable-transcript or .segment-text selectors, the break was complete until developers pushed new updates — sometimes taking days or weeks.

Extensions that are actively maintained get patched eventually. Extensions that are abandoned or slow to update leave users with broken workflows and no recourse.

How INDXR.AI Works Without an Extension

INDXR.AI is a web application you access at indxr.ai. There's nothing to install. You paste a YouTube URL into the tool and it processes the video server-side — not through your browser's DOM, not through a content script running on the YouTube page.

The extraction pipeline uses yt-dlp, a maintained open-source tool that communicates with YouTube's internal data endpoints rather than scraping page HTML. When YouTube updates its frontend, yt-dlp continues working because it talks to the underlying API, not the visual layer that changes with UI redesigns.

For videos without auto-captions, INDXR.AI downloads the audio through the same server-side pipeline and sends it to AssemblyAI Universal-3 Pro for transcription. This means INDXR.AI works for:

  • Videos with auto-captions (instant, free)
  • Videos without auto-captions (AI transcription, 1 credit per minute)
  • Videos in any of the 67 languages YouTube auto-captions support
  • Videos in 99+ languages via AssemblyAI when auto-captions aren't available

Works in Any Browser

Because INDXR.AI is a web application rather than a Chrome extension, it works in:

  • Chrome, Firefox, Safari, Edge, Arc, Brave — any modern browser
  • Mobile browsers on iOS and Android
  • Chromebooks without extension support
  • Corporate environments where extensions are restricted

You're not limited to one browser, and you don't need extension permissions that read your browsing history or modify page content.

What You Get vs. a Typical Extension

Most transcript extensions give you the raw YouTube caption text — the same text you'd see if you clicked "Show transcript" on the YouTube page itself. INDXR.AI gives you the same starting text but adds a processing and export layer that extensions typically don't have:

8 export formats — TXT plain, TXT with timestamps, Markdown with YAML frontmatter (for Obsidian/Notion), SRT, VTT, CSV, JSON, andRAG-optimized JSON.

Resegmented SRT/VTT — YouTube's raw subtitle segments are 2–4 seconds each. INDXR.AI resegments to 3–7 second blocks at 42 characters per line — the broadcast standard — without any manual editing.

AI transcription fallback — When a video has no auto-captions, no extension can help you because there's nothing on the page to extract. INDXR.AI switches to audio-based AI transcription automatically.

Persistent library — Transcripts are saved to your account and searchable. Re-export in a different format months later without re-extracting.

Playlist processing — Extract transcripts from entire playlists in a single background job.

For Users Who Prefer Browser-Based Workflows

If you want to extract transcripts while browsing YouTube without leaving the page, a browser extension is genuinely more convenient for that specific workflow. INDXR.AI requires an extra step: copy the URL, open the tool, paste the URL. For heavy users who extract dozens of transcripts while browsing, that friction adds up.

What INDXR.AI offers instead is reliability and depth. The workflow is slightly slower per video but never breaks unexpectedly, works across all browsers, handles videos without captions, and produces output that extensions don't.

To extract your first transcript without installing anything, paste any YouTube URL in the generator. For background on how the server-side pipeline works, see how INDXR.AI works. For credit costs, see the pricing page.

Frequently Asked Questions

Does INDXR.AI work on mobile?
Yes. INDXR.AI is a responsive web application accessible on iOS and Android browsers. Paste a YouTube URL from the YouTube app, open INDXR.AI in your mobile browser, and extract the transcript. No mobile app installation required.
Is there a browser extension version of INDXR.AI?
Not currently. The product is web-only by design — server-side extraction is more reliable than browser-based DOM scraping. A browser extension is on the post-launch roadmap but not a current priority.
Can I use INDXR.AI in Firefox or Safari?
Yes. Any modern browser that supports JavaScript works. Chrome extensions like Glasp or the Obsidian Web Clipper are Chrome/Edge-only; INDXR.AI has no such limitation.
Does it work on corporate networks where extensions are blocked?
Yes. INDXR.AI is a regular web application with no browser extension required. If your organization blocks Chrome extension installation, you can still use INDXR.AI normally through any allowed browser.
What about the YouTube mobile app — can I extract transcripts from videos I find there?
Yes. Copy the share link from the YouTube mobile app, open INDXR.AI in your mobile browser, and paste the link. Standard YouTube video URLs and shortened youtu.be/ links both work.
