Mind Palace - Memory Train

A precise Method-of-Loci toolkit. Encode content into spatial cues, train in two phases, score by accuracy and speed. Fully on-device, zero tracking.

Mind Palace is an engineered implementation of the Method of Loci, the spatial-memory technique used by world memory champions. It converts arbitrary text into structured spatial cues and drives you through a measurable two-phase training loop.

ENGINE

• Imagery layer: each input is mapped to (icon, palette hue, scene caption, keyword set) by an on-device deterministic mapper, no LLM, no network
• Three theme-coherent route layouts: Castle, Forest, Space Station, each with 8 landmark cue sets
• Stable encoding: the same input produces the same cue, supporting repeated rehearsal

TRAINING PROTOCOL

• Phase 1 Memorize: walk the route, observe the visual encoding for each peg
• Phase 2 Recall: blind input on each peg, accuracy graded per peg
• Score = accuracy x 0.7 + speed x 0.3, baselined at 180 s
• Tournament mode persists scores to a local leaderboard for longitudinal tracking

PRIVACY AND FOOTPRINT

• 100% on-device. No accounts, no analytics, no remote endpoints, no third-party SDKs
• All palaces and tournament records persist in local UserDefaults
• No background activity. App is dormant when closed.

USE CASES

• Vocabulary acquisition (L2 learning, GRE/IELTS)
• Formula and definition retention (medical, engineering)
• Speech and pitch rehearsal (sequential cue chains)
• Procedural lists (checklists, routines)

REQUIREMENTS

• iPhone, iOS 17 or later
• No connectivity required at any point

Train with intent. Measure with rigor. Mind Palace ships the algorithm of antiquity in a clean, modern, and verifiable form.
