◐ Waitlist open · Shipping Q3 2026

Everything you watch, listen to,
and read — turned into ideas you keep.

Retainly is a mobile app. Save any video, podcast, or article with one tap — it transcribes the whole thing, pulls out the key ideas, and keeps them searchable for good. The library remembers, so you don't have to. But if you want to, we help with that too.

A YouTube video you watched
Now 14 ideas you keep
The Retainly mobile app showing a saved YouTube video, 'How focus actually works' by Andrew Huberman, transcribed and turned into 14 ideas with recall tracking — proof the app keeps what you watch.

I just can't find it.”

YOUR YEAR, BY THE HOUR

A small library, consumed.
Almost none of it findable.

The average young pro logs hundreds of hours of YouTube, hundreds more on podcasts, and reads roughly a long article a day. Different shelves, same library — except your tools treat it like a stream, and the stream is unrecoverable. The numbers below are estimates for an average week-of-the-life. Yours will differ.

YOU CONSUME YOU CAN FIND Hours of YouTube ~520 / year ~3 hours Hours of podcasts ~340 / year ~10 hours Articles & Substacks read ~580 / year ~30 of them Retainly: saves it. tracks it. keeps it yours.
What you actually consumed What you can still find
Order of magnitude estimates drawn from Nielsen Audio, Edison Research “Infinite Dial,” and Substack platform data. Your weekly numbers will be different — that's the point of tracking them.
HOW IT WORKS

Tap share. We do
the sorting.

You already save things. Spark — the quiet intelligence inside Retainly — does the rest: transcribing the videos, listening through the podcasts, reading the Substacks, and sorting it all, so your habit becomes a library you can actually use.

Search when you need.
Look back when you want.

Ask the way you'd ask a friend: “that YouTube video about systems”, “the podcast where he mentioned salt”. Inside the videos, inside the audio. Yes, inside. Or open a Look Back prompt and see what stayed.

The honest mirror.
What you actually watched, heard, read.

Tracking is the magnet. Once you can see how much you really consume — and on what — it gets easier to be intentional about what stays. No streaks. No nagging. The numbers are just yours.

REMEMBER MORE OF WHAT MATTERS

Finding it is one thing.
Keeping it is another.

Most of what you watch and listen to slips. Within a week, an honest 80% is gone. Look Back is the quiet part of Retainly that pushes against that — short prompts that surface what you saved, the way you'd revisit a great book.

You pick the depth: a single video, a single episode, or a synthesis across everything you've consumed on a topic. Two minutes a week, no homework energy.

Off by default. On when you're ready.

HOW IT FEELS
You watched something great. A week later, it's gone. Look Back catches a few of those a week — not to test you, just to ask "anything stay with you?" The ones that do, stick. The ones that don't, the library remembers for you.

In your own words: why did Carthage stay with people long after Rome won?
The salt thing wasn't literal — it was symbolic. Rome wanted to end the story of Carthage, not just the city. The memory was the threat.
FOR WHEN YOU WANT IT TO STICK

Look back gently —
or actively recall.

Look Back asks softly. Recall goes a step further — a few quick questions that turn what you saved into memory you can actually use. Type an answer or pick one; Spark checks it, and you can push back if you think it’s wrong.

And you choose the reach: recall just one source, or take on a whole topic across everything you’ve saved — connecting threads and building on what you already know.

Optional, never a test. Two minutes, your pace.

Just one source Questions from a single thing you saved.
A whole topic Across sources — build on what you’ve learned. 3 sources connected

Across what you saved on systems thinking: why does feedback delay make systems so hard to steer?
Cause and effect are separated in time, so the correction always arrives late.
BBecause systems are too large for one person to model.
CBecause feedback is usually negative rather than positive.

Quick answers.

What sources work?
YouTube, podcasts (any RSS feed or major player), articles, newsletters, Substack, Medium, Reels and TikToks with captions, and pretty much any web page you can share to an app. If it has text we can read — or audio we can transcribe — it goes in the library.
How is this different from Readwise, Pocket, or Notion?
Those are storage. You file, you tag, you misplace. Retainly does the filing for you — by topic, entity, date, even by tone. It searches inside videos and audio, not just titles. And it slowly learns what you actually care about. Look Back (a quiet 90-second prompt, optional) is on top for the days you want to remember, not just find.
Do I have to use Look Back?
No. Most people will use Retainly as a library — save, search, find, move on. Look Back is off by default. Turn it on when you want it. Turn it off whenever. It's a feature, not a personality.
What's the difference between Look Back and Recall?
Two ways to remember, both optional. Look Back is gentle — it asks “anything stay with you?” and you write a sentence; nothing is graded. Recall is active — a few quick questions Spark checks, and you can push back if it's wrong. Either one can cover a single source or a whole topic across everything you've saved.
How does the search work?
Two layers. (1) Plain keyword: it just works. (2) Semantic: ask for “that YouTube video about systems” and it'll find Hannah Fry even if neither word appears in the title — the exact words don't have to be there.
Will it be free?
There'll be a generous free tier — save, search, and find without paying. A few advanced pieces (deeper synthesis, unlimited Look Back) will sit in a paid plan. Waitlist members get the first month of anything paid, on us.
When does it ship?
Beta in late summer, public launch Q3 2026. Waitlist members get in first and shape what gets built.
What about privacy?
Your library is yours. We don't sell data, we don't train models on your saves, and the “your attention” map never leaves your account. Standard email + social login. Export everything anytime.
