Tubuki — Bulk YouTube Transcript Downloader

Tubuki downloads available YouTube transcripts from a single video, a public channel, or an individual playlist. Filter a bulk selection by video title and publication period, then save separate files in a ZIP or merge the transcripts into one Markdown or text file for AI-assisted research. Use Tubuki when you want to understand what is useful in a channel, decide which videos deserve your time, or explore an author’s ideas with your own AI tool. You choose the source material and download it locally; you choose whether and where to upload it afterwards. Understand a channel before subscribing Want to know whether an author is worth following? Collect the available transcripts from their public channel and enable “Merge into one file” in the transcript settings. Upload the resulting file to an AI tool that accepts documents, then ask it to identify recurring themes, explain the author’s main arguments, or suggest videos relevant to your interests. Example prompt: “Using these transcripts, what does this author focus on? Which videos should I watch first if I care about practical AI applications? Point me to the source video titles and URLs.” This gives you a starting point for choosing what to watch more closely. Transcripts capture spoken content; demonstrations, charts, tone, and other visual context still belong in the original videos. Research a channel’s videos about AI When a project needs a focused selection rather than the whole back catalogue: 1. Open the channel. In transcript settings, choose your format and enable “Merge into one file” if you want a combined document. 2. Choose the transcript-download action to open the video-selection dialog. 3. Enter a word or phrase such as “AI” in the video-title filter. 4. Choose Any time, Past 24 hours, Past 7 days, Past 30 days, or Past 12 months. 5. Preview the matching videos before starting the download. 6. Download the available transcripts and upload the file to your preferred AI tool. Example prompt: “What problems do these videos identify about AI adoption? Group the arguments by theme, show disagreements, and link each point to its source video.” The keyword filter matches video titles, not words inside transcripts. A video can discuss AI without naming it in the title. For broader coverage, leave the title filter blank and explore the downloaded text with your AI afterwards. Publication-period filters are approximate because YouTube rounds the dates shown on video cards; they are not custom start-and-end date filters. Study or analyse a playlist Use the same workflow for a public playlist of lectures, interviews, tutorials, or talks. Download the available transcripts in playlist order, or narrow the selection with the title and publication-period filters. Merge them into one document so your next tool can work with the collection together. Example prompt: “Treat these lectures as a course. Explain the main concepts, identify which lecture introduces each one, and suggest questions I should revisit in the original videos.” You can also compare material from separate channel or playlist exports. Keep the source titles and URLs when asking AI to compare arguments, find contradictions, or suggest follow-up viewing. Save one video’s transcript When you only need a single video, open its YouTube watch page and use the transcript-download action. Choose the available caption track, Markdown or plain text, and your preferred timestamp and metadata settings. Download one local file for reading, notes, quoting, or an AI conversation about that video. You do not need to start a channel or playlist export for this. Individual video downloads also support YouTube-provided auto-translations when those tracks are available. Choose the file your next step needs - Merge bulk transcripts into one Markdown (.md) or plain-text (.txt) document for a document-upload workflow. - Keep bulk transcripts as separate files in a ZIP when you want to organise or process videos individually. - Use Markdown for structured reading or an Obsidian vault; use plain text for a simpler text-processing workflow. - Turn transcript timestamps on or off and choose the optional video details to include. Every merged transcript section includes its video title and source URL so you can return to the original. An incomplete collection is marked at the start of the merged file. Separate-file exports keep the metadata options you select. Know what the export contains Tubuki downloads existing caption tracks when YouTube makes them available. Choose a detected auto-generated original track or an available creator-uploaded track. A video without a usable selected track is skipped; the extension does not create a transcript from audio. Bulk downloads run one item at a time and show progress, an estimate, and cancellation. If YouTube requires verification, processing stops and the successful results are offered in your selected merged-file or ZIP format. Cancelling an export does not download a partial result. Keep the YouTube page open and your computer awake while an export runs. Questions before your first export Can I chat with a channel inside Tubuki? Tubuki prepares the source files. Upload them yourself to an AI tool that accepts documents to discuss the channel, ask questions, or compare ideas. There is no built-in AI chat, automatic AI upload, or AI-generated summary. Can one file contain an entire channel or playlist? One merged file can contain the available transcripts from your selected channel or playlist videos. Caption availability, YouTube verification, browser memory, and your AI tool’s file-size and context limits affect how much material you can use at once. Narrow the selection or use smaller exports when needed. Can I search everything an author said about a topic? Tubuki filters video titles before downloading. To look for a topic mentioned only within videos, collect a broader set of transcripts and search or analyse those…
