Sigilla – A read-later app that deletes unread links using spaced repetition

Summary: Sigilla manages your reading list with a spaced repetition algorithm that resurfaces unread articles and deletes those skipped repeatedly. It exports highlights as Markdown, allowing data ownership and integration with note-taking systems.

What it does

Users save articles via browser or mobile, then Sigilla uses spaced repetition to prompt reviews. Links that are ignored multiple times decay and are deleted to keep the list actionable.

Who it's for

It is designed for users who want to avoid accumulating unread articles and maintain a focused, manageable reading list.

Why it matters

Sigilla addresses the problem of endless unread link collections by enforcing review and removal, helping users convert saved content into actual knowledge.
