Every broker records what you own. Nothing records why. Six months on you can see a position is down 14% and have no idea whether the reasoning was wrong or the timing was.

So: write the thesis when you open a position, put a number on how strongly you believe it, and let the app bring it back to you later and ask.

Everything below is missing on purpose. Each one is a real product, and each one would make this a worse journal.

It does not do the research. No screeners, no analyst ratings, no fundamentals, no earnings calendar, no valuation models. The thinking is the part you are supposed to do; a tool that did it for you would leave you with a thesis you cannot defend, which is the opposite of the point.

It does not track fundamentals. No P/E, revenue, margins or debt. If those matter to your thesis, write them into it — in your words, with the number you actually looked at and what you concluded. That sentence will still mean something in two years. A live P/E chart will not tell you what you were thinking.

It is not a portfolio tracker. It does not connect to your broker, sync positions, or reconcile anything. Trades are typed in by hand, and only so the journal knows roughly what you held and when. Your broker already does the accounting, and does it better.

It does not tell you what to buy. No recommendations, no signals, no alerts, no sentiment scores, nothing generated by a model pretending to have a view. The only opinions here are the ones you typed.

It is not a trading screen. Prices are yesterday’s closes and update once a day. If you need to know what something is doing this minute, this is the wrong window to have open.

It is not tax software. The cost basis shown is average cost, for your own orientation. Do not file anything from it.

What is left is narrow and deliberate: a place to write down what you believe and why, and something that brings it back and asks whether you were right.

A position is one ticker. It has a status — watching, open or closed — and your trades normally set it: the first buy opens it, selling the last share closes it. You can override the status by hand, but the next trade will move it again.

The ticker itself cannot be changed after creation. It is the position’s identity, and changing it would make it a different position rather than a corrected one.

Entries are the journal. A thesis is the original case, an update is something changing, a review is looking back, and an exit is why you got out.

Each can carry a conviction score from 1 to 10. The chart on a position draws those scores as steps, not a curve, because a score holds at whatever you last recorded until you record another. You did not drift from 8 to 6 over four months — you believed 8 until the day you wrote 6.

The most useful sentence in any thesis. Write down what would have to happen for you to be wrong, and the app will put it back in front of you at review time and ask directly whether any of it happened.

Without it, a review is “how do I feel about this now”, which is a question you can answer any way you like.

Set a review date on an entry and it appears in the review queue when the date arrives. Reviews must be at least a day out — one set for today arrives already overdue.

Your previous conviction is hidden until you commit a new score. That is deliberate. Seeing the old number first anchors the new one, and an anchored review tells you very little. Your stated falsifier is shown, because that is the question being asked rather than the answer. A price commitment works the same way: the price you said you would act at is shown, because that too is the question — paired with what you actually paid once you commit a score, not before.

The dashboard also surfaces positions that have gone quiet — things you still hold but stopped writing about. Nothing else would tell you, because no review was ever scheduled.

Every price in the app is the previous trading day’s closing price. One per ticker per day. Not a live quote, not an intraday price, and never a number that moves while you are reading it. The tape at the top of the page shows the date those closes belong to, and so does the holding panel on a position.

On a Tuesday you are seeing Monday’s close. On a Monday you are seeing Friday’s. That is one session behind on purpose, for two reasons.

The first is what this app is for. It exists to make you write down why you bought something and read it back months later. A price ticking in the corner pulls attention toward the last fifteen minutes, which is the exact habit the journal is meant to interrupt. A number that only changes once a day is one you cannot usefully stare at.

The second is honesty about cost. Live and delayed market data is licensed, and the fees are charged per person you show it to. Yesterday’s closing prices are not. Building on daily closes keeps this affordable at a price a single person can pay, rather than charging more for a live number that would make the app worse.

Because of that, market values and returns are as of the last close — not as of this second. For deciding whether a thesis is playing out, a day makes no difference. For anything where the last few hours matter, use your broker.

A position with no recorded price shows no market value rather than a zero. A missing price is not a value of zero.

For each buy, the conviction you had recorded at the time against the return from what you paid to the latest close. It answers the question the whole app is built around: when you were confident, did you buy well?

A score written after a purchase is not counted. That is why the page can look empty even when you clearly have trades — if you entered historic trades and wrote the theses today, no score preceded a buy. Counting them would let hindsight into the one measurement that exists to keep hindsight out.

It also refuses to draw conclusions from too little. A handful of trades is an anecdote, and the page says so rather than drawing a confident chart.

Any position can be published to a read-only link. Anyone with the link can read it; it is not listed or indexed.

Your trades are hidden by default. The reader sees the reasoning and the conviction, not the size of your position, unless you explicitly turn trades on for that link. The link preview follows the same rule. Revoking a link takes effect immediately and permanently.

Case, spacing and punctuation are collapsed automatically, so “AI Infra”, “ai-infra” and “aiinfra” are one tag. Plurals resolve against tags you already have.

For splits no rule can catch — “semis” versus “semiconductors” — rename one onto the other from tag settings and they merge.

Your journal is private. Positions, entries and trades are visible only to you, except on a share link you created yourself.

Deleting an entry never deletes a trade — a trade that cited it keeps its numbers and loses the link. Deleting a position deletes everything under it.
