Recall

Recall is a personal AI encyclopedia for individuals who want a read-it-later workflow that also summarizes and makes saved knowledge searchable and chat-ready across devices.

Key capabilities include:

• Save and summarize content from sources such as articles, PDFs, YouTube videos, podcasts, Google Docs, and personal notes, with one-click AI summaries
• Chat with saved knowledge to ask questions across everything stored in the knowledge base
• Automatic organization using smart tags and a knowledge graph that links related ideas (including Graph View)
• Review for retention with spaced repetition, plus full-text and semantic search to resurface key information

Pricing: Freemium with Recall Lite ($0/month), Recall Plus ($7/month), and Recall Business (custom pricing).

What makes it notable: Recall combines AI summarization, a self-organizing knowledge graph, and active recall (spaced repetition) in one system, with cross-platform access via web apps, iOS/Android mobile apps, and Chrome/Firefox browser extensions, plus data export in Markdown.
