Retention isn’t about rereading — it’s about [[spaced retrieval]]. Ebbinghaus showed the curve in 1885; the fix is to be reminded right before you’d forget. That’s what [[resurfacing]] should do — not a feed, a nudge.
A blank page in under a second. Web clipper, email-in, voice memos transcribed. Everything lands in one inbox and nothing is lost to a tab you closed.
Type [[ and link to any thought you've ever had. Backlinks appear automatically. Over months, a structure emerges that no folder tree could have predicted.
Search that understands meaning, not just keywords. Old notes resurface next to new ones. You stop re-learning what you already knew.
“I used to have four hundred notes I never reopened. Now I have four hundred notes that keep reopening me.”
Unlimited notes, semantic search, end-to-end encrypted sync, publishing.
