Summary

Why teams that ship many cheap experiments outperform teams that plan one expensive launch — and how to size a bet so that losing it costs you a week instead of a quarter.

Key Points
  • 4:12

    Large launches concentrate risk into a single decision made at the point of least information — the beginning.

  • 6:58

    Teams read a long build as commitment; the market reads it as absence.

  • 11:40

    Cap any single experiment at two weeks. Past that, you are no longer testing an idea, you are defending one.

  • 19:05

    If you cannot name the signal that would end the experiment, you do not have a hypothesis yet.

  • 33:58

    Twenty discarded options leave behind a map of the problem space that no single success would have produced.

The problem

You watched 25 minutes to get 8 minutes of value.

You didn't want the intro, the sponsor read, or the third restatement of point two. You wanted the part that mattered — and a way to find it again next month.

How it works

Three steps, and two of them are ours.

  1. second 0

    Send a link

    Paste a YouTube URL into the bot, or hit the button on the video page once the extension ships.

  2. second 15

    We read the video

    Subtitles when they exist, our own transcription when they don't. Then the video gets classified — a tutorial is not a podcast and shouldn't be laid out like one.

  3. about a minute

    You get a note

    Summary, key points, sections, insights. Every point carries the second it came from, so a claim you doubt is one click from its source. Long videos, and the ones we have to transcribe ourselves, take a few minutes rather than one.

The note

Structure, not a paragraph.

Transcribers give you words. Summarizers give you a paragraph. A note has parts, and the parts point back into the video.

Summary
One or two sentences: who this video is for, and whether it's worth your 47 minutes.
Key points
Three to seven ideas, each standing on its own without the surrounding context.
Sections
The video broken along its own structure, timestamped.
Insights
The non-obvious part — what you'd have underlined if you were taking notes by hand.
Action items
Concrete steps, when the video is the kind that has them.
Resources
Books, tools, names and links mentioned along the way.

The layout follows the video: a tutorial comes back as numbered steps, a podcast as the thread each speaker was pulling, a review as what held up and what didn't.

Where it runs

Wherever you were already watching.

Telegram

Available now

Share a video to the bot from your phone and the note lands in the chat about a minute later. No account, no app to install.

Browser extension

Coming soon

A button next to the player. The panel opens beside the video, and clicking a point seeks the player to that second.

Web

Available now

Everything you've ever clipped, in one place, searchable. This is where a pile of notes turns into a knowledge base.

Depth

Decide how much of it you want.

Same video, five lengths — all of them on every plan, free included. Skim the ones that turn out to be filler, go deep on the ones that don't. Or ask for a clean transcript and read the thing yourself.

Essence

1 min

The gist and the three to five points that carry it. For deciding whether the video deserves more of your time.

Brief

2–3 min

Sections with the two or three points each that you'd regret missing.

Normal

4–6 min

The full note, laid out along the video's own structure. The default, and where most people stay.

Detailed

8–12 min

Examples, caveats, and the quotes a summary would drop. For talks you're actually studying.

Full

as long as it is

Not a note — the whole transcript, cleaned up. Filler gone, paragraphs, speakers, headings, timestamps.

Questions

The ones that come up.

Why not just read the auto-generated transcript?+

A transcript is the same 47 minutes, in text. No hierarchy, no separation of signal from filler, and nothing to search across videos. A note is 23 points, grouped by section, each linked to its second in the video.

How do I know the AI didn't invent things?+

Every point carries the timestamp it came from. If a claim looks off, one click takes you to the source and you verify it in five seconds. That's the whole reason timestamps are non-negotiable for us.

Does it work for videos without subtitles?+

On Starter and above, yes — we transcribe the audio ourselves. The Free plan works with videos that already have subtitles, which is most of YouTube but not all of it.

What languages does it handle?+

Anything YouTube handles. The note comes back in the language of the video, whatever language you read the app in.

Why is there no sign-up form?+

Because you don't need one to try it. Send a link to the Telegram bot and you'll have your first note before a signup form would have finished loading. The web account comes later, when you want the knowledge base.

Is my data used to train models?+

No. We use the paid APIs of OpenAI, Google and Anthropic, and none of them train on data sent that way. We don't train anything of our own either.

What happens when I hit my limit?+

Nothing is deleted. Your notes stay where they are; you either wait for the next period or move up a plan.

How are hours counted?+

A minute of video is a minute of your plan: a forty-minute talk uses forty minutes, whatever detail level you pick. Two things are counted on top, and both show before you press the button. A video without subtitles also uses transcription hours, because we transcribe the audio ourselves. And a note on the best model counts at least ten minutes, because even a one-minute clip costs it real work. If your best-model hours run out, we finish the note on Balanced rather than refuse it, and the note says which model wrote it.

How long do you keep my notes?+

Indefinitely, on every plan including Free. We don't delete notes when a period ends or when you downgrade.

The next video you were going to half-watch.

Send it to the bot instead. You'll know in a minute whether it was worth the 47.
