How it works

Three steps to never forget an idea

Share from any app on your phone, or save directly from your browser with the extension. Just one tap.

Every link is processed automatically: reads the content, creates a concise summary, tags the topic and classifies by intent.

Chat with your knowledge base. Loci answers with precise citations from the articles you've saved.

Features

Every article, video or tweet is summarized concisely, helping you grasp the content in seconds.

Search by meaning instead of exact keywords. Ask "articles about long-term investing" and Loci understands what you need.

Ask questions and get answers synthesized from all your saved content, with citations to each source.

Receive a summary of your saved articles via Telegram or Email every morning, in your own timezone.

Visualize topic clusters over time. See clearly how your interests grow and connect.

Save links from Chrome, Edge or Brave with a single click or right-click. No need to leave the page.

Knowledge constellation

Every topic you save becomes a star on the map. One glance tells you which areas you read the most, and which ones you haven't touched in a while.

Size is the number of saved articlesThe more articles a topic has, the bigger its star.
Brightness is recencyBright stars are topics you just read. Without new saves, a star slowly fades.
Lines connect neighbouring topicsNearby stars are joined into constellations, just like on a real star chart.
