Keep it,

your commitments

Make a pact with friends, put in an Entry Fee and prove you did it. The AI Arbiter checks your photo, PayPal settles the pool.

How it works

  1. Make a pact

    Create a challenge, set a deadline and an Entry Fee, and invite your friends.

  2. Prove it

    Take a photo with your secret proof code. The AI Arbiter checks it.

  3. Settle up

    Those who made it get their fee back plus a share of the fees of those who didn't.

About us

We're a small team of four from Poznań. We built KeepIt because we know how easy it is to promise "I'll do it tomorrow" and then quietly let it slide. We want to help people stick to their goals, and to make keeping commitments more fun by turning them into challenges with friends.
