Hi. We're Yak Tack.

Yak Tack is an app that helps people remember words and improve their vocabulary. People are using Yak Tack to remember words right now:

Try it out!

Type any word you can think of above. We like "apocryphal" and "peripatetic."

It works. But don't take our word for it. We're featured in:

We help people remember words with spaced repetition.

Spaced repetition is a scientifically proven technique used to boost memory recall by flattening the Forgetting Curve. We use it. It combats a natural phenomemon called memory decay, in which words we remember become harder to retrieve over time.

We use an algorithm based on the Leitner system that re-surfaces words at expanding intervals just before they fully decay, which ironically strenghens one's ability to remember them.

In practice, when you want to remember what a word means, we remind you of it frequently at first, then less frequently as time goes on.

We call this process "tacking."

We're big around the world.

People around the world are using Yak Tack to learn English. And we make it easy to remember what words mean in your native language.

Check out the definition of "ostensibly" in Japanese or Spanish.

Like newsletters? We have one.

We love words. We're tired of forgetting what they mean.

Ever engage in a conversation around a campfire and hear someone use the word ostensibly a couple times? Ever pull out your phone to look it up?

ostensibly: as appears or is stated to be true, though not necessarily so; apparently

Ever peruse an article the following week, where "ostensibly" shows up, only to realize you forgot what it means?

We have.

It's better with people.

We didn't know that "ostensibly" was a word until our friend used it around the campfire. Other people expose us to new words.

We've made it easy for you to connect with people on Yak Tack who are learning new words too. When they start tacking a new word, we'll tell you about it. They'll be your campfire friend.

Here are the most popular words this month. Click on a few to see who's been tacking them.

Hey power users, we're also headless.

What we mean is, you can use Yak Tack without using Yak Tack. Want to remember a word? Email word@yaktack.com with the word as the subject, and we'll take it from there. Power users love headless Yak Tack.

Try it. Type a word or term below, then click NEXT.

Type any word or term you can think of above. We like "erudite" and "pareto principle."

Does it cost anything?

Yak Tack is fully functional for free. But for $2.00 (USD) per month, Yak Tack is even better. Don't worry about that now. Start tacking for free. We'll talk about money later if we need to.
