An early night does more for recovery than any gadget.

Example answer to "Does red light therapy help recovery?" It uses three things you saved months apart, from a physio, a sports scientist, and a friend. The physio and the sports scientist disagree, and the answer shows both views.

How it works

How Cordance works

Noise

Save it

Share a post, article, video, or podcast from any app, or type a thought of your own.

Signal

Cordance reads it

Cordance finds the claims in each save. Each claim keeps who said it, when, and the exact words it came from.

Your mix

Everything you save, connected.

Nobody follows your exact mix of people. That mix is you.

A physio on Instagram. A sports scientist on a podcast. A friend on X. An author you read in May. They have never met, and nobody else follows all of them. Cordance links what they said, so one question draws on them all.

Nothing comes from a feed or an algorithm. Every connection starts with something you chose to save. Switch a voice off and watch your Cordance change.

7 voices · your Cordance

Your Cordance, drawn in sand by the seven voices you saved. Amara Osei is a physio, Kofi Arnesen a sports scientist, Jess Tan a friend, Ines Valdrake an author, Kettle Hill Runners a running channel, Leo Varga an economist, and Noor Hadley a chef. Switching any voice on or off changes its shape.

Sides, not verdicts

When your sources disagree, you decide.

Amara and Kofi cannot both be right. Cordance puts their claims side by side, with the post and the podcast they came from, and leaves the call to you. Pick one, keep it split, or mark it as not a conflict. You can change your mind at any time.

Concord and discord share a root, cor, the heart. So does our name.

ConcordJess Tan and Ines Valdrake both say most runs should feel easy. Their sand settles into one shape.
DiscordAmara Osei and Kofi Arnesen say opposite things. Their sand forms two shapes at once.

Red light therapy speeds up muscle recovery.

Cordance never picks a side for you.

Example conflict card. It offers four choices: pick Amara, pick Kofi, keep it split, or mark it as not a conflict.

Your view, on record

Say what you think. It counts too.

Under every claim Cordance finds, tap Yes, No, or Don't know, and add a reason if you want. Saved something you disagree with? Tap No. A Yes or a No joins what Cordance knows, with you as the source, and your view comes first in every answer on that point.

Example Agree check. Under Kofi Arnesen's claim that red light therapy speeds up muscle recovery, you answered No and gave a reason. Cordance saved it as your view, and your view now comes first when you ask about red light therapy.

Why this matters

When everyone asks the same few AIs, the handful of people who build them decide what those AIs call true.

Cordance answers only from the people you chose. You weigh what they say, and you decide what you believe.

Artificial intelligenceTwelve people ask the same few AIs, and get the same answer.
Personal intelligenceTwelve people ask their own sources, and no two answers match.

A billion different minds instead of one.

You saved it for a reason. Now ask it something.
