Decision Protection

What decision are
you protecting?

You have a position, a thesis, a route, a call you're relying on. EdgeLetter reconstructs the reasoning behind it, identifies what would break it, and watches the world for developments that challenge it.

In your own words — EdgeLetter finds the assumptions.

The 3 days start when you protect your first decision, not when you sign up. After the trial, continuing protection is a paid upgrade you choose.

EdgeLetter investigates the reasoning behind your decision, identifies what could change it, and watches for developments that challenge it.

Two ways to protect a decision.
Start with either.

EdgeLetter checks your decision against what is being reported now and, if you choose, keeps checking it for you.

Before you commit

Investigate it, right now

Paste a decision into the box above, in a meeting or on the move. You do not have to protect it first.

  • The assumptions your decision quietly depends on
  • What would break each one, in plain words
  • What public reporting and official data say about each today, with the article, the source and the dates
  • An honest “not enough evidence” when the evidence is not enough
After you commit

Monitor it, so you do not have to

Protect the decision and EdgeLetter keeps checking its assumptions against the world, and stays quiet until something is genuinely challenged. Try it free for 3 days.

  • Every decision kept as a permanent, dated record
  • You are told when an assumption is challenged, with the evidence
  • Every revision of your reasoning preserved
  • Nothing to re-check by hand
What an investigation looks likeIllustration of the format. Not a live reading of any event.
“We’ll route Q4 cargo through the Strait of Hormuz, assuming it stays open and war-risk insurance stays below 15%.”
The strait stays open to commercial shippingBeing challenged
Breaks ifcredible reporting shows commercial transit being closed or sharply restricted
Shows the article, who published it, the date it was published and the date of the event it describes.
War-risk insurance stays below 15%No verdict
Breaks ifa quoted war-risk premium rises above 15% of the insured value
When the evidence is old, thin or contradictory, EdgeLetter says so instead of guessing.
Alternative routes remain available at similar costCurrently holds
Breaks ifreporting shows the alternatives closed, or their cost sharply higher
“Holds” means nothing found so far contradicts it. It is never a promise about the future.
Where reports disagree, EdgeLetter shows both sides and the exact passages rather than choosing one for you.

What this is, and is not. EdgeLetter does not predict events and does not give investment advice. It reads your decision, tests its assumptions against public news and official data, and shows its evidence so you can check it. It uses AI to read your decision and summarise reporting, and mistakes are possible. Open the linked source and confirm anything that matters.

Built for decisions that events can undermine

An investor holding a thesis, a shipping analyst choosing a route, a risk team signing off a plan, a journalist tracking a story: each relies on assumptions that can quietly stop being true. EdgeLetter makes those assumptions explicit, shows what would break each one, and keeps a dated record. See pricing or read our approach.

Questions people ask

What is decision protection?

Decision protection means testing the reasoning behind a decision before you commit, then watching for developments that challenge it afterwards. EdgeLetter lists the assumptions your decision depends on, states what would break each one, and checks them against public news and official data.

Can I investigate a decision before protecting it?

Yes. Paste a decision into the box and EdgeLetter investigates it right away, so you can use it in a meeting or on the move. You do not have to protect the decision first. Your first investigation is free.

How does the 3-day free trial work?

The 3 days start when you protect your first decision, not when you sign up. There is no card at sign-up. After the trial, continuing protection is a paid upgrade you choose.

Does EdgeLetter predict events or give investment advice?

No. EdgeLetter does not predict events and does not give investment advice. It tests the assumptions in your decision against public reporting and shows its evidence so you can check it yourself.

Does EdgeLetter use AI, and can it be wrong?

Yes. EdgeLetter uses AI to read your decision and summarise reporting, and mistakes are possible. When the evidence is old, thin or contradictory it says so instead of guessing. Open the linked source and confirm anything that matters.

Who is EdgeLetter for?

Anyone relying on a call that could be undermined by events: investors holding a thesis, shipping and trade analysts choosing a route, risk teams, and journalists tracking a story.

Start with an investigation.
Protect what matters.

EdgeLetter doesn't ask you to keep re-checking whether the reasoning behind an important decision still holds. It watches — and stays quiet until something genuinely matters.
