The Problem

You're consuming. Not learning.

You've saved 500 videos you'll never watch. Read 200 articles you can't recall. Your bookmarks are a graveyard — not a knowledge base.

Information Overload

500+ tabs, hundreds of saved videos, and you can’t remember any of it. More saved doesn’t mean more learned.

Passive Learning

Watching feels productive. But without active recall, nothing sticks. Passive consumption is not the same as understanding.

No Retention System

Knowledge is scattered across platforms with no way to review, connect, or actually use what you’ve consumed.

“Your browser tabs are where knowledge goes to die.”
The Solution

Your personal knowledge retention system

SmartRetain AI transforms everything you consume into structured, actionable knowledge — one you’ll actually be able to use.

AI Summaries

Get structured summaries in seconds — overview, key points, and actionable takeaways. No more re-watching.

Smart Quizzes

AI-generated multiple-choice quizzes from any content. Turn passive watching into active recall that sticks.

Spaced Repetition

Science-backed flashcard intervals using the SM-2 algorithm. Review at the exact right moment for your memory.

Chat Your Knowledge

Ask “What did I learn about React hooks?” and get precise, cited answers from everything you’ve ever saved.

Universal Capture

YouTube, Medium, Twitter/X, LinkedIn, Substack — one place for all your learning, whatever the source.

Cross-Platform

Web app, mobile app, and Chrome extension. Capture anywhere, review everywhere, never lose context.

Who it’s for

Built for lifelong learners

If you’re serious about learning, this is your second brain.

Developers

Students

Learners & Researchers

Turn lectures, textbooks, and YouTube into study materials that adapt to your memory — so you ace the exam without cramming.

Entrepreneurs

Founders & Knowledge Workers

How it works

Three steps to lasting knowledge

It takes less than 30 seconds to go from content to retained knowledge.

  1. Save

    Paste any link or use the Chrome extension to save content in one click — YouTube, articles, tweets, anything.

  2. Learn

    AI automatically generates a summary, quiz, and flashcard deck. You get structured knowledge without the effort.

  3. Retain

    Practice with quizzes, review flashcards on the optimal schedule, and ask your knowledge base anything.
