Head to head — written by the Mettle team, biases disclosed
Chartlog is known for clean, low-friction trade analytics — log in, sync, see your stats without ceremony. Mettle adds the ceremony on purpose: a structured review ritual and a coach, because the ritual is what changes behavior. Different bets; here is how to pick.

Who should choose which
Feature by feature
Mettle: A structured Full Session Review ritual: emotion tags, execution self-scoring, and leak capture on every trade, walked through after each session.
Chartlog: Journaling and analytics with deliberately low ceremony; what you do with the stats is up to your own process.
Mettle: Cass, an AI coach grounded in your own journal — she reflects the data you logged, holds the one thing you said you are working on, and writes a read of your day after the close.
Chartlog: None — Chartlog’s bet is that clean analytics are enough, which is honest and right for some traders.
Mettle: Honest by design: insights are framed as "based on what you reported," never fabricated pattern-mining. No software can see inside your head, so Mettle does not pretend to.
Chartlog: Notes are available; psychology is not a first-class data type.
Mettle: Mettle keeps analytics deliberately behavior-focused (BRI score, process metrics, leak patterns) rather than maximizing report count. If you want the widest possible report library, that is a real reason to pick the other tool.
Chartlog: Clean per-symbol and per-setup stats with a famously simple interface — the genuine reason traders pick it.
Mettle: Live broker sync on supported brokers, plus CSV import from any broker with AI-assisted column mapping.
Chartlog: Direct platform integrations for supported brokers.
A note on pricing
Mettle starts free: 14 days of full access with no card. After that, Apprentice is $19.99/month — $9.99/month founding rate for the first 50 continuously subscribed members.
Chartlog is a paid subscription; plans change, so check their pricing page for current numbers. If you only need clean stats, their entry plan may be all you ever use — pay for the loop you will actually run.
FAQ
No — Chartlog’s clean, simple analytics are exactly right for traders whose review process already works. Switching makes sense when seeing your stats has stopped translating into different decisions at the next session.
Yes. Export your trades to CSV from Chartlog (or re-export from your broker) and import them into Mettle — the importer handles any broker's CSV with AI-assisted column mapping, so your history comes with you.
It depends on the failure mode you expect. If you mostly need to see your numbers, Chartlog is a gentle start. If you already know your problem is discipline — revenge trades, moved stops, oversizing — start with the tool whose daily loop confronts that directly.
You should not take it on faith — that is why every section names where the other tool genuinely wins, and the why-switch section runs in both directions. Trial both: log a real week of trades in each and keep the one you actually open every day.
Mettle wraps your numbers in a session review ritual and a coach who remembers what you are working on. Free for 14 days, no card — bring your history with a CSV.
