Tradezella is the most feature-complete of the three but also the most expensive. Chartlog falls in the middle with screenshot focus and affordable pricing. Stonk Journal is the stripped-down option. If you are comparing all three, you are deciding how much complexity you need and how much you are willing to pay for it.

All three fall short in one key area
Tradezella, Chartlog, and Stonk Journal cover three different journaling styles: replay-focused analytics, screenshot annotation, and minimalist stock logging. Each is a solid tool for its audience. The gap they all share is real-time feedback: none detect behavioral patterns during a live session. SuperTrader fills that gap — live AI every 2 minutes, a free plan with no trade limits, and automatic broker sync.
