🔍 Data Source: YouTube Captions (Not AI Transcription)
This tool does not perform speech-to-text transcription directly from audio. Instead, it retrieves the caption track (subtitle data) already available on YouTube's platform. There are two types of captions that can be extracted:
- Manual Captions — Created manually by the channel owner or community contributors. Generally more linguistically accurate; may include punctuation, paragraph breaks, and spelling corrections.
- Auto-generated Captions (ASR) — Generated automatically by Google/YouTube's Automatic Speech Recognition (ASR) system using deep learning models (similar technology to Google Speech-to-Text). Accuracy varies depending on audio quality, speaker accent, and vocabulary coverage in the target language. Punctuation is often absent.
⚙️ Technical Pipeline
- Your browser sends the Video ID (an 11-character identifier, e.g.
rn66ueqj6mo— not the full URL) to the Supadata API (supadata.ai), a third-party proxy service that bridges the browser and YouTube. - Supadata forwards the request to YouTube's Player API to retrieve the list of available caption tracks, including their language and type (manual or ASR).
- Once a language is selected, the tool downloads the subtitle file in XML/TTML or JSON3 format directly from YouTube's caption server (
youtube.com/api/timedtext). - The caption file is parsed client-side in your browser — each text segment along with its
starttime anddur(duration) in seconds is extracted and rendered on screen. - The entire process runs inside your browser. No video is ever uploaded. No audio data is transmitted to any server.
📐 Output Formats & Research Use Cases
- With Timestamps (.TXT) — Format:
[HH:MM:SS] text. Suitable for discourse analysis requiring time references, segment-based qualitative coding, or verifying quotations against the original video. - Plain Text — Full transcript without timestamps. Ideal for thematic analysis, text mining, or as a corpus for Natural Language Processing (NLP) tasks.
- .SRT (SubRip Subtitle) — Industry-standard subtitle format with sequential numbering, time ranges (
start --> end), and text per segment. Directly compatible with annotation tools such as ELAN, InqScribe, Transana, VLC, and video editors like DaVinci Resolve or Adobe Premiere for verification and coding.
⚠️ Limitations Researchers Should Be Aware Of
- Transcript accuracy depends entirely on the quality of captions available on YouTube. Auto-generated captions may contain transcription errors, especially for proper nouns, technical terminology, or regional dialects.
- Captions do not always include correct punctuation or sentence boundaries (particularly auto-generated ones). Researchers are advised to perform post-editing before using the transcript as primary data.
- Some videos have no captions at all — the creator may have disabled them, the video may be too recent for ASR to process, or it may be a live stream recording.
- This tool cannot access private, paid, or age-restricted videos as no account authentication is performed.
- Free usage limit: 100 requests per day via the Supadata API. For large-scale research, consider upgrading your Supadata plan or deploying your own Cloudflare Worker as an alternative proxy.
🔒 Privacy & Data Security
Only the Video ID is sent to an external server. No video content, audio, user identity, or browsing data is collected or stored. All text processing and transcript rendering happens locally in your browser (client-side only).

How to Extract a YouTube Transcript
YouTube Verbatim retrieves the caption track (subtitle data) already available on YouTube's platform — it does not perform speech-to-text from audio. The tool sends only the video ID to the Supadata caption API, which bridges the browser and YouTube's caption server. All text processing and rendering happens locally in your browser.
Step 1 — Paste the YouTube URL
Copy the URL of any public YouTube video and paste it into the input field. The tool accepts all URL formats: full youtube.com/watch?v= links, shortened youtu.be/ links, YouTube Shorts URLs, and embed URLs. A thumbnail preview of the video appears instantly to confirm you have the right video.
Step 2 — Select Language (if multiple are available)
If the video has captions in more than one language, a Caption Language dropdown appears. You can choose between any available manual subtitle tracks and auto-generated (ASR) caption tracks. Manual captions are generally more accurate and may include punctuation. Auto-generated captions are available in more languages but may lack punctuation and have occasional transcription errors.
Step 3 — Extract and Read the Transcript
Click Extract Transcript. The transcript appears in the right panel with three stats: total segments, word count, and video duration. Use the view toggle to switch between With Timestamps (each segment prefixed with [HH:MM:SS]) and Plain Text (full transcript without timestamps). Use the search box to find and highlight any word or phrase within the transcript.
Step 4 — Copy or Download
Click Copy to copy the transcript to your clipboard in the current view format. Or download as:
- .TXT — Timestamped transcript in
[HH:MM:SS] textformat. Suitable for qualitative research, discourse analysis, or time-coded documentation. - .SRT — SubRip Subtitle format with sequence numbers, start/end timestamps, and text per segment. Compatible with VLC, DaVinci Resolve, Adobe Premiere, ELAN, InqScribe, and Transana.
Common Use Cases
- Academic research — Extract verbatim transcripts from interview recordings, lectures, or documentary content posted to YouTube for qualitative coding and analysis.
- Content repurposing — Convert YouTube video content into blog posts, articles, or social media captions by starting from the extracted transcript.
- Language learning — Use timestamped transcripts to follow along with foreign-language videos, look up vocabulary in context, or practice listening comprehension.
- Accessibility — Create text versions of video content for hearing-impaired viewers or for environments where audio is unavailable.
- SEO and subtitles — Download the SRT file to add or correct subtitles in your own video editing workflow or to create closed captions for re-uploads.
- Note-taking — Extract and search lecture or tutorial transcripts to quickly find specific explanations or timestamps without re-watching the video.
Frequently Asked Questions
Does this work with auto-generated captions?
Yes. The tool retrieves both manual subtitles (written by the channel owner or community contributors) and auto-generated captions produced by YouTube's Automatic Speech Recognition (ASR) system. If a video has both, a language dropdown lets you choose. Auto-generated captions are available for most videos in popular languages but may lack punctuation and occasionally contain transcription errors on technical terms or accented speech.
Why can't I extract captions from some videos?
Captions may be unavailable for several reasons: the channel owner has disabled captions on that video; the video was uploaded recently and YouTube's ASR system has not yet processed it (usually takes a few hours); the video is a live stream or premiere recording without a published caption track; or the video is private, age-restricted, or members-only. The tool only works with publicly accessible videos that have at least one caption track enabled.
What formats can I download the transcript in?
.TXT — A plain text file where each caption segment is prefixed with a [HH:MM:SS] timestamp. Suitable for reading, qualitative research coding, and text analysis. .SRT — SubRip Subtitle format, the industry standard for subtitles. Each entry has a sequence number, start–end time range, and the caption text. Compatible with all major video editors (DaVinci Resolve, Adobe Premiere, Final Cut) and annotation tools (ELAN, InqScribe, VLC).
Is this tool safe to use for sensitive research data?
Only the video ID (an 11-character public identifier) is sent to the caption API. No video content, audio data, user identity, or browsing history is collected or stored anywhere. All transcript parsing and display happens client-side in your browser. The tool does not require any account and has no access to your Google account or YouTube history.
What is an SRT file and how do I use it?
SRT (SubRip Subtitle) is the most widely supported subtitle format. Each entry contains: a sequence number, a start → end timestamp in HH:MM:SS,ms format, and the caption text. You can open SRT files in VLC (drag onto a playing video), import them into DaVinci Resolve or Adobe Premiere as subtitle tracks, or use them in annotation tools like ELAN and InqScribe for qualitative research coding.
Are private or age-restricted videos supported?
No. The tool only works with publicly accessible videos that have captions enabled. Private videos, age-restricted videos, and members-only content require account authentication, which this tool does not perform. No YouTube login is involved at any point.
How accurate are the extracted transcripts?
Accuracy depends entirely on the quality of the captions available on YouTube. Manual captions created by the channel owner are typically highly accurate. Auto-generated captions can be 85–95% accurate for clear audio in major languages, but accuracy drops for heavy accents, background noise, technical jargon, or less-resourced languages. For research purposes, it is recommended to review and post-edit auto-generated transcripts before treating them as primary data.
Is there a limit on how many transcripts I can extract?
The free tier of the underlying Supadata API allows 100 requests per day. For most individual users this is more than sufficient. If you need higher volume — for large-scale research or batch processing — you can upgrade your Supadata plan or self-host a proxy via a Cloudflare Worker to route requests directly without the daily limit.
Why Use Alfreto YouTube Verbatim?
Most YouTube transcript tools are cluttered with ads, require a Google login, have strict daily limits, or only offer plain text without timestamps. Alfreto's tool is clean, fast, and built with researchers and content creators in mind — with proper timestamped output, SRT export, and in-transcript search.
[HH:MM:SS] timestamp — making it easy to locate any quote within the original video, cite a source accurately, or jump to a specific moment.
