kappi vs Chartlog: Two Products at Almost Exactly the Same Price
Chartlog's Lite tier is $14.99 a month; kappi is $15.00. They differ by one cent, which makes this the one comparison where price tells you nothing at all. What separates them is whether the record is assembled after the trade or sealed before the fact.
| kappi | Chartlog | |
|---|---|---|
| Price | $15/month ($12.75 via a referral link) | $14.99/mo |
| Higher tiers | None — one tier | Standard $29.99, Pro $39.99 |
| Record assembled | Before the fact | After the fill |
| Fixed once committed | Yes | No — entries stay editable |
| Third party can verify | Yes — anchored publicly | No |
| Annual cost at entry tier | $180 | $179.88 |
Why compare two products that cost the same?
Because it removes the argument people usually have. $14.99/mo[1] against $15 is a difference of one cent a month, twelve cents a year. Nobody is choosing between these on budget, so whatever you decide is a decision about what the record is for.
Chartlog's ladder goes further up — Lite tier; Standard $29.99/mo and Pro $39.99/mo — so a fuller comparison at the top of their range is $39.99 against $15, and kappi has only the one tier.
What do you get for $15 in each case?
From Chartlog: a journal that ingests your trading and reports on it, at the entry tier of a three-tier product. From kappi: a recorder that fixes what you said before the fact and publishes it where it can be checked.
Those are not competing answers to one question. They are answers to two questions that traders routinely conflate:
- "What is my trading actually doing?" — a journal question, answered by analysis of trades that already happened.
- "Why should anyone believe me?" — a record question, answered only by evidence that the call preceded the outcome.
Broker-import journals prove what you did after the fact, from data you control. kappi timestamps what you said you would do, before you knew how it would turn out, on a record you cannot edit.
Can a journal ever answer the second question?
Not structurally. Every field in a journal is written by the person the journal is about, after the market has already answered, into a row that stays editable. That is not a criticism of any specific product — it is what a journal is, and it is why the honest recommendation here is often "run one of each" rather than "switch".
A commit is sealed before the fact and released on a time-capsuled delay.
Every sealed commit is hashed into a Merkle tree and anchored to Hedera, so the log is append-only and independently checkable.
When should you pick Chartlog?
When you want reporting on your own trading and nobody is asking you to prove anything. At $14.99/mo for Lite it is priced at the bottom of the journal market, and if analysis is the gap, that is $179.88 a year better spent than on a proof you have no reader for.
When should you pick kappi?
When there is a reader. $15 a month, $12.75 through a referral link, and no free tier. Of the 17 track-record and journal services surveyed on 2026-08-15, none combined all three: capture that works with any brokerage or your own journal, a seal whose opening time you choose, and a proof anchored in public so it can be checked without the platform's cooperation.

Frequently asked questions
How much does Chartlog cost?
The Lite tier is $14.99 a month, with Standard at $29.99 and Pro at $39.99, as listed on their pricing page in August 2026.
Is kappi cheaper than Chartlog?

What does kappi do that a journal at the same price cannot?
It seals each commit before the fact and anchors the log to a public ledger, so an outsider can confirm the timing without trusting kappi or you.
Should I run both?
Many traders should. At list price both entry tiers together are $29.99 a month, and they answer different questions — one about your execution, one about your credibility.
