Memory  ·  by design

Remember anything by design.

Transform words, formulas, and dates into a journal of vivid mental scenes. volvel.io pairs your imagination with a rotating wheel born in 1267, tuned for the way your brain actually works. Journal the scene. Lock in the memory.

The problem

Most of what you read is gone within a week.

Highlighters and flashcards fight a losing battle against the forgetting curve. The brain struggles to hold onto raw data — but it holds fiercely onto scenes. Smells. Surprises. Stories. The vivid stuff sticks.

volvel.io is a mnemonic machine that turns anything you need to remember into scenes your brain refuses to forget.

The method

A 14th-century instrument, re-engineered for your brain.

01step

Type your target

A word, phrase, formula, date or concept. Add a box for each chunk — easier → e, a, s, i — and volvel.io turns each chunk into a memory scene.

02step

Spin the wheel

Four rings of letters rotate independently. Each ring stands for an Agent, Action, Object, or Circumstance.

03step

Cast the scene

The pointer lands on four letters. You name the cast: 'Astronaut unwraps umbrella at a window.' Strange. Vivid. Sticky.

04step

Lock it in

Journal the sequence into your shelf — a personal memory journal you can review or re-cast anytime. The wheel makes every memory unique to you.

Cast the whole phrase as one vivid scene — a person, an action, a thing, a place. Remember the scene, and the words come back.

Features

The wheel is where it starts. Not where it ends.

volvel.io has grown into a full memory studio: wheels to invent memories, a shelf to keep them, notes to catch the rest, and graphs to connect everything into one map you can walk through.

Memory wheels

Spin a scene into place

Type your target and split it into chunks. Four rings of letters rotate until each chunk meets its anchor — and every alignment prompts a vivid scene only you could invent.

Scenes & the Shelf

A journal your brain can replay

Journal each scene frame by frame, then keep them all on a searchable memory shelf. To recall the target, you simply rebuild the story you wrote.

Learning paths

One path per subject

Group wheels and notes into learning paths — one per language, course, or project. Create, rename, archive, or delete them from a workspace sidebar that holds everything.

New · Graphs

Link it all into a mind map

Wheels remember the pieces. Graphs remember how the pieces fit together. Create as many named canvases as you like and link any wheels and notes into free-form mind maps — the same wheel can live in many graphs.

  • Drag, pan, zoom. Arrange nodes by hand, or tap Auto-arrange and let the canvas tidy itself.
  • Tap to act. Select a node for Open, Link, Colour, and Remove. Double-tap to jump straight into the wheel or note.
  • Name the connections. Draw links between nodes and give them labels; colour nodes to group ideas.
  • Never lose your place. Every wheel and note lists the graphs it belongs to, and a breadcrumb leads you back to the map. Positions, links, and colours are all saved.
Notes

Catch what doesn't fit a wheel

Flip the capture toggle from Wheel to Note and write freely inside any path. Type, dictate with your voice, or attach a quick voice memo — notes sit beside your wheels and join your graphs.

Review

Review by rebuilding

Return to your shelf, reopen a scene, and rebuild it from memory before you reread it. Recall the story, and the target follows — review that feels like replaying a film, not grinding flashcards.
