How TubeZen works

Part one

Four ways to capture something without watching it

Pick whichever suits the moment. Most people end up using two: a channel follow for the creators they trust, and a playlist save for everything else they stumble across.

Save to a YouTube playlist

This is the one that does the most work. Connect your YouTube account, tell TubeZen which playlist to watch, and from then on saving a video to that playlist is all it takes — from the desktop site or the YouTube app on your phone.

You never open the video. You never see the sidebar. We check your playlists every fifteen minutes, so by the time you next sit down the summary is already in your inbox.

1 Connect YouTube from Settings, under the YouTube section.
2 Choose a playlist to follow — many people make one called "TubeZen".
3 On YouTube, tap the three dots on any video and pick Save to playlist.

Searching for YouTube channels to follow inside TubeZen

Follow a channel

For creators you already trust, skip the decision entirely. Search for a channel by name, follow it, and TubeZen backfills its recent uploads straight away and then keeps pace with new ones.

We check followed channels every three hours. You can also follow a channel from inside any summary, which is usually when you realise you want more from that creator.

Search a topic and import a batch

When you are researching something rather than following someone, search YouTube by subject from inside TubeZen. Tick the results that look useful, import them in one go, and they arrive summarized and filed under a category named after your search.

This is the fastest way to go from "I know nothing about this" to twenty summaries you can skim in half an hour — without ever landing on youtube.com.

One click from the video page

Our Chrome extension adds a TubeZen button to every YouTube page, so a video you have stumbled onto goes into your inbox in a single click — no playlist, no pasting.

Not on the Chrome Web Store yet — but you can run it today. The listing is in review. Meanwhile you can load the extension into Chrome yourself in a couple of minutes; the download includes instructions. Or skip it entirely — saving to a playlist does the same job, needs no install, and works on your phone as well.

The whole loop works on your phone

This matters more than it sounds. The moment you notice something worth reading is usually the moment you are holding your phone — so saving to a playlist works straight from the YouTube app, and TubeZen installs on the same device to read it back.

On Android and desktop Chrome your browser offers to install it. On iPhone, open TubeZen in Safari and tap Share, then Add to Home Screen. Either way it opens in its own window, with no tabs and nothing one click away from YouTube.

Shows work the same way, in the same inbox

There is no separate podcast app to learn. Search for a show by name, follow it, and new episodes arrive summarized alongside your videos — same triage, same categories, same search across everything.

Search and follow

Thousands of shows are searchable by name. Follow the ones you already subscribe to elsewhere and we check them every three hours.

Read instead of listening

A three-hour conversation becomes a structured read with timestamps. When something is worth hearing in full, the built-in audio player has the same speed controls and 10-second skips as the video player.

Or have it read to you

Turn your new summaries into a short spoken episode published to a private feed you add to any podcast app — included with the lifetime license.

What comes back

Every summary has the same shape, so you learn to read it fast:

Overview: Who is talking, about what, and why it matters — three lines.
Key takeaways: The substance, as bullets. Each one opens the video at the moment it was said.
Steps: For how-to content only: the actual procedure, numbered and timestamped.
Notable quotes: The lines worth remembering, with the timestamp to hear them delivered.

How-to videos also get a Detail Score from 1 to 10 — how specific and repeatable the advice actually is. A 9 gives you exact settings and tools; a 2 tells you to "be consistent". It is the fastest way to skip something that sounds useful and is not.

Working through it, then being done

Everything you capture lands in Unreviewed. You read the summary and make one call, which takes seconds:

Save

Worth keeping. Pick a category and it files itself there, searchable forever.

Snooze

Interesting, wrong moment. It disappears and comes back when you asked for it.

Delete

Not worth it. Gone, and you spent two minutes instead of forty.

Or automate it

Subscription

For a channel you trust completely, a rule saves every new upload into a category without asking.

The point of an inbox rather than a feed is that it ends. When Unreviewed is empty you are finished for the day — and your dashboard shows how many hours of watching you skipped to get there, priced at whatever you decide your time is worth.

Getting it out again

A library you cannot get at is just a nicer landfill. Everything you save can leave TubeZen for the tool you actually think in.

Your AI assistant Lifetime

TubeZen runs an MCP server, so Claude, ChatGPT, Gemini, Cursor or VS Code can search your library directly. Ask a question in plain English and your assistant answers from the things you actually watched, not the open web.

Obsidian Lifetime

Our plugin writes every saved summary into your vault as a clean, linkable note, grouped by channel or show, tags and timestamps intact. See the Obsidian plugin.

NotebookLM

Select a batch of saved videos and TubeZen hands you the source list to drop into a notebook. For podcasts, where NotebookLM cannot read an audio feed, it builds one Markdown file per episode with the summary and the full transcript — so the notebook reasons over the real source rather than a summary of a summary.

Video source lists are on every plan; podcast transcript exports need the subscription.

Email and audio digests Lifetime

Have your new summaries written up as one email on your own schedule, in whatever tone and length you ask for — or read aloud as a short episode on a private podcast feed.
