What EdgeLetter actually does

You decide. EdgeLetter investigates, then protects.

01
You decide.
You make the decision. Always. EdgeLetter never tells you what to buy, sell, or believe — and never will.
02
EdgeLetter investigates.
It identifies the assumptions your reasoning depends on, and matches them against a permanent archive of corroborated evidence.
03
EdgeLetter protects.
Once monitoring begins, it continuously checks whether those assumptions still hold — and interrupts you only when they materially change.
EdgeLetter never tells you what to believe.
It continuously checks whether the reasons behind your decision are still holding.
Why decisions fail

Decisions rarely fail at the moment they're made.
They fail quietly, later.

Without continuous monitoring
Decision made — reasoning sound at the time
The world changes
Assumptions quietly weaken
Nobody notices
The decision is never revisited
With EdgeLetter
Decision made — reasoning recorded permanently
EdgeLetter identifies every assumption underneath it
Evidence monitored continuously
You are told when an assumption weakens
The decision stays informed
Investigate anything important

Not a market feed. Whatever you're actually weighing up.

Tap any example to start an investigation with it — or write your own above.

What your investigation looks like

Five screens. Then it never stops working.

Screen 1
Your decision
In your own words. No format, no jargon required.
Screen 2
The assumptions underneath
EdgeLetter identifies what has to stay true for your reasoning to hold. You can edit them, or add your own.
Screen 3
Related records
Real, timestamped Protection Cards from the archive matched to your assumptions — each independently auditable.
Screen 4
Review your reasoning
Edit, remove, or add. EdgeLetter never changes what you meant — it records it.
Screen 5
Activate monitoring
Your reasoning is frozen as a permanent Decision Record and continuous checking begins.
Next
Evidence DossiersComing
Supporting and contradicting evidence assembled per assumption, before you decide.
Monitoring never sleeps

What arrives once your decision is protected.

Morning Brief Built
What deserves your attention today — and, most mornings, the fact that nothing does.
Protection Cards Live
Only when an assumption materially changes. Never on a schedule. Never as filler.
Weekly Calibration Built
Which assumptions strengthened, which weakened, which decisions deserve a second look.
Decision History Live
Every version of your reasoning, preserved permanently. Nothing is ever deleted.
Respect Report Coming
A monthly account of everything EdgeLetter checked on your behalf — including the quiet weeks.
The record, publicly auditable

We don't ask you to trust it. We ask you to check it.

Loading live figures…
Every figure above is queried live from EdgeLetter's production database at the moment this page loaded. When the pipeline is paused, you see the real number — never an invented one.
Check it yourself

Two real records. Both auditable to the original source.

EdgeLetter is early in its life and does not publish customer testimonials it does not have. What it publishes instead is the archive — including the records where the conditions changed and the records where nothing could be concluded.

PC-0057 · Energy 8 sources
Iran reimposed Strait of Hormuz vessel restrictions amid Israel–Lebanon attacks
Recorded with its timestamp, then corroborated by two editorially independent publishers under the RECOG_v3 standard. Eight independent sources are on record. The assumptions documented on the card held through the review window.

PC-0019 · Global Conditions changed
Israel–Lebanon ceasefire development documented as conditions shifted
The conditions underneath this card changed during its review window, and that change is documented with its sources and the time it was observed. It remains in the archive exactly as recorded — because a record that removes its inconvenient entries is not a record.

Questions

Straight answers.

Can EdgeLetter tell me what to invest in?
No. It never recommends buying or selling anything, and it does not rate or evaluate any security or instrument. It identifies the assumptions behind a decision you've already reasoned through, and checks whether they still hold. The decision stays yours.
Can I monitor business decisions, not just investments?
Yes. Suppliers, sourcing locations, expansion plans, strategic commitments — anything whose reasoning depends on conditions that can change.
Can I edit my reasoning?
Yes, at any time. Every revision is preserved as a new version — your original reasoning is never overwritten.
Can I stop monitoring?
Yes. Monitoring can be paused or stopped whenever you choose, and you can cancel your subscription at any time from your dashboard.
Can I delete a decision?
No. Decision history is permanent — that's the point. A record you can quietly delete is not a record. Your history stays yours even if you cancel.
Do I need to be technical?
No. Write your decision the way you'd explain it to a colleague. EdgeLetter does the structuring.
Is this financial advice?
No. EdgeLetter is decision-documentation and monitoring software. It is not a financial services provider or adviser, does not provide investment advice or portfolio management, and never holds or moves client funds.

What are you weighing up right now?

Write it down. In sixty seconds you'll see the assumptions your reasoning rests on — and EdgeLetter will keep checking them long after you've closed this page.
