stacktube

Videos stream by.
Knowledge should stack up.

Lectures, breakdowns, tutorials — you can't watch them all. Stacktube watches the channels for you, picks what's worth your time, and stacks the rest as notes.

STACKTUBE — CHAPTER I
01 — Filter

This isn't a summary tool.
It's a filter for what's worth watching.

Three minutes with the note for what doesn't need watching. Real time only for what does.

01

Endless subscription feed

10 channels means 5–10 videos a day. No time to spot the one you actually need.

02

30 min watched, 3 days later: nothing

You watched to the end and can't recall the gist. A one-page note would have cost 3 minutes.

03

Summaries are just a table of contents

"This video discusses X" doesn't tell you whether X is worth your time.

Register once, done

From new-video detection to delivery, hands-off. The note structure adapts to the video type (framework, tutorial, analysis, explainer, news) — compare them in the gallery tabs above.

STEP 1

Register a channel

Just paste the YouTube URL. New videos auto-detected.

STEP 2

AI reads deeply

Identifies the type and judges whether you should watch yourself.

STEP 3

Structured note

Two AIs cross-analyze — a note you can actually use.

STEP 4

Auto-delivery

Sent to Obsidian · Email · Drive · E-ink automatically.

STACKTUBE — CHAPTER II
02 — Stack

Knowledge that stacks
must be findable again.

Other tools stop where the analysis ends. Stacktube starts there.

Questions?

Can it handle videos without captions?

Yes — any video with YouTube auto-captions works at any length. Without captions, we fall back to a lightweight analysis from title and description.

Will I be charged automatically after the trial?

No. When the trial ends, you drop to the free Starter plan. We don't take payment details upfront.

Do free-plan users get notes automatically?

Yes. One channel, weekly auto-analysis, weekly digest. Daily across all channels starts at Pro.

How does Obsidian integration work?

Via the official Obsidian community plugin — notes flow straight into your vault after a one-time API key paste. Pro plan or above (Starter delivers via web and email).

What's the monthly issue (EPUB)?

A month of your notes bound into a single book, delivered to Kindle · Email · Drive. Max-only.
