Memorize anything.

Remember almost anything by typing it from memory

memo turns whatever you need to remember (a password, a hard-to-spell word, a phrase or PIN) into a quick typing drill. You type the whole thing each round while the on-screen hints fade: most of the letters show at first, then fewer and fewer, until you’re recalling it entirely from memory. That gradual, active recall is what moves something from “I just read it” to “I know it by heart.”

What people use memo for

• Passwords you can't write down

  Commit a new password, passphrase, or recovery phrase to memory before you rely on it, without leaving a copy anywhere.

• Words that never stick

  Nail the spelling of a tricky word, a name, or a term in another language by recalling it letter by letter.

• Phrases, PINs & lines

  Learn a quote, a PIN, a phone number, or a few lines by heart through quick, repeated recall.

Frequently asked questions

How do I memorize a password?

Type the password into memo and practice it across a few rounds. Each round hides more of the letters, so you move from copying it to recalling it from memory. Because everything stays in your browser, you can drill a password you don't want to write down anywhere.

How can I remember the spelling of a word?

Enter the word and type it back as the hint letters fade out. Spelling it from memory, one letter at a time, is far more effective than reading it over and over. That active recall is what makes it stick.

What's the best way to memorize a phrase or PIN?

Short, repeated recall beats cramming. memo shows the whole phrase, then fades the hints round after round until you can reproduce it unaided. It's a quick, low-effort way to learn a PIN, passphrase, or a line you need by heart.

Is it safe to type a password here?

Yes. memo runs entirely in your browser. There's no account, no server, and nothing you type is ever sent or stored anywhere. Close the tab and it's gone.
