About this tool
Build virtual memory palaces using the method of loci — organize rooms and objects with associations to boost recall.
The Memory Palace Builder is a three-level outliner for the method of loci: you create palaces, add ordered rooms inside them, and place objects in each room with an association and optional notes. A built-in review mode then walks every object in room order, showing the object name first and hiding the association until you press Reveal, so you can self-test recall rather than reread. Students, speakers and competitive memorisers get a structured palace that saves to the browser and exports as JSON.
Open Memory Palace Builder on AltFTool — it loads instantly in your browser.
Press 'New Palace', then add rooms with the 'Room' button and loci with 'Add Object', filling each 'Object Name' and the 'Association' you want to recall.
Press 'Review' to walk every object in room order — the association stays hidden until you press 'Reveal Association', with a progress bar across the palace.
Edits autosave to this browser's localStorage; the export button downloads memory-palace-YYYY-MM-DD.json and 'Import' loads it on another machine.
Rooms and objects can be moved up or down, so the walking route stays fixed — the sequencing the method of loci depends on.
Review mode shows the object and hides the association behind a Reveal button, with a progress bar across all objects in the palace.
Everything exports to a dated JSON file and imports back, so a palace survives a new browser, machine or profile.
It is a mnemonic technique where you attach each item you want to remember to a distinct location along a familiar route, then mentally walk the route to retrieve them in order. It works because spatial and visual memory is far easier to traverse than an abstract list, which is why the ordering of rooms and objects matters here.
In your browser's localStorage under the key altf-memory-palace-data, saved automatically after every edit. Nothing is sent to a server, but clearing site data or browsing in a private window will remove it, so export the JSON if the palace matters.
Keep it small — most practitioners place roughly 3 to 5 distinct loci per room so no two objects blur together at the same spot. There is no hard cap in the builder, so if a room feels crowded, split it into two rooms rather than stacking objects.
The object is the physical anchor already in the room (the lamp, the doorknob); the association is the vivid image linking that anchor to what you are memorising. Review mode shows the object and hides the association, so writing them the other way round makes self-testing useless.
