Kinen – A read-later app focused on retention through AI and spaced repetition

Summary: Kinen is a read-later app designed to help users retain and understand saved content using AI-powered summarization, explanations, and spaced repetition. It supports capturing articles, videos, tweets, and PDFs, offering a calm interface without unread counters or inbox anxiety.

What it does

Kinen captures various content types via browser extensions and applies AI to summarize, explain, and enable search across the library. It uses spaced repetition through a Memory Loop and Daily Ritual to optimize long-term retention.

Who it's for

It is intended for users who save content to learn from it and want to improve retention rather than just bookmarking for later reading.

Why it matters

Kinen addresses the common issue of forgetting saved content by focusing on what users remember, not just what they save.
