RecallLoop

About

Reading is easy. Remembering — and actually understanding — is the hard part. RecallLoop turns reading into learning.

Select any passage on any page and choose a "lens" for exactly the kind of help you need. RecallLoop explains it in plain language using AI, right where you're reading — no copy-pasting into another tab.

Four built-in lenses, one for each way you get stuck: • Define — "I don't know this word" • Rephrase — "I can't parse this sentence" • Explain — "I don't understand this idea" • Examine — "I don't follow the argument"

Make it yours. Create custom lenses with your own prompts — an analogy, a steelman, a translation, whatever fits how you read.

Save what matters. Turn any explanation into a card. Your cards live in a clean Library, searchable and organized by lens.

Remember it for real. RecallLoop schedules your saved cards for review using spaced repetition (an SM-2-style algorithm) — the proven method for moving knowledge into long-term memory. A quick Review session brings each idea back right before you'd forget it.

Built to respect you: • No account required. • No tracking, no analytics, no ads. • Your cards and notes are stored locally on your device. • Only the text you choose to act on is ever sent for an explanation.

Great for students, researchers, lifelong learners, and anyone who reads to learn.
