Know your stuff Know it all Know it Cold

Most of what you need to know lives in the parts of a document you haven't read — and the knowledge you haven't used — in months. Recall can resurface it before you really need it.

The Problem

You learned it.
But unused knowledge fades.

Long-term memory doesn't hold knowledge equally. What you use daily stays sharp. What you don't use — procedures, regulations, protocols, edge cases — retreats. Not gone, but inaccessible under pressure, which amounts to the same thing.

Recall forces regular retrieval of that dormant knowledge before it's needed. Daily. Automatically. Without you having to decide what's at risk of fading.

80%.
of critical knowledge sits unused in long-term memory — present but inaccessible under pressure
50%.
of what you learn is forgotten within a week without active retrieval practice
5 min.
a day with Recall is enough to keep your full knowledge base active and retrievable
How Recall Works

Simple. Systematic.
Unstoppable.

01
Import anything
Upload a PDF, paste a URL, or drop in raw text. Feed Recall any source of knowledge — manuals, regulations, protocols, references — and it structures everything automatically.
02
Random by default
Every day's queue pulls from across your entire knowledge base — not just the comfortable, well-worn material. Dormant knowledge gets forced back into retrieval whether you'd choose it or not.
03
Smart scheduling
Rate your confidence after each section. Recall's SM-2 algorithm resurfaces knowledge at the exact interval your memory needs it — sooner for what's fading, later for what's solid.
04
Notes built in
Attach context to any memory — mnemonics, personal hooks, key details, edge cases. Every time that knowledge surfaces again, your notes are right there with it.
05
You set the pace
Five minutes a day keeps years of knowledge accessible. Set your goal in minutes or sections — Recall fills your queue accordingly, never more than you asked for.
06
Multiple documents
Your entire knowledge base — every manual, regulation, protocol, and reference — managed in one place. Each source tracks independently, so nothing falls through the cracks.
Coverage Map

Watch the darkness
illuminate.

Recall coverage map — each cell represents a section of your document
Every section is a memory

Each square in the map represents one unit of knowledge. Dark means it hasn't been retrieved. Lit means it's active and alive.

Amber means fading

Sections glowing amber are overdue for retrieval — memory is degrading. That's Recall telling you what's at risk before you need it under pressure.

Tap any cell to read it

The coverage map isn't just a stat — it's a navigation tool. Tap any section to open it directly.
