Chartlog: Overview

Chartlog has earned a following by doing something simple very well: providing a clean, visually appealing trading journal that is easy to start using immediately. Its free tier is one of the most accessible entry points in the trading journal space.

What Chartlog does well:

• Clean, modern UI — one of the best-designed trading journals in terms of visual clarity
• Generous free tier — you can journal a meaningful number of trades without paying anything
• Fast onboarding — you can start logging trades within minutes of creating an account
• Chart annotations — attach and annotate chart screenshots directly on your trades
• Low learning curve — straightforward interface that does not overwhelm new users

Where Chartlog falls short:

• Analytics are basic — P&L tracking and simple breakdowns, but no deep behavioral analysis
• No AI analysis or automated pattern detection
• No Discipline Score or structured behavioral metrics
• No prop firm challenge mode
• Limited broker integrations for auto-sync

TradeLens: Overview

TradeLens shares Chartlog’s emphasis on clean design but adds a full AI coaching layer. The platform is built around the idea that tracking trades is only useful if it leads to behavioral change — and behavioral change requires automated detection of patterns you cannot see yourself.

What TradeLens does well:

• AI Bias Detector — automatically identifies revenge trading, overtrading, FOMO, and other costly patterns
• Discipline Score — five-axis behavioral metric that tracks improvement over time
• Prop Challenge Mode — real-time drawdown tracking for FTMO, Apex, The5ers, and others
• Universal CSV import — auto-detects columns from any broker export
• Shareable dashboard — granular privacy controls for sharing performance data

Where TradeLens falls short:

• Newer platform with a smaller user base
• No native mobile app yet (responsive web interface)
• The AI features might be more than a casual trader needs

Feature Comparison

For beginners: Chartlog is arguably the better starting point if you have never used a trading journal before. Its simplicity is a feature, not a limitation. There is almost no learning curve, and you can focus purely on building the habit of logging trades.

For intermediate to advanced traders: Once you have the journaling habit, the question becomes "now what?" Chartlog shows you what happened. TradeLens shows you what happened and why it keeps happening. The AI Bias Detector identifies recurring behavioral patterns that basic analytics cannot surface.

Design quality: Both platforms have modern, clean interfaces. Chartlog’s chart annotation feature is particularly well-executed. TradeLens’ Discipline Score visualization and AI insight cards are its design highlights.

Prop firm traders: If you trade funded accounts, TradeLens has a clear advantage with its dedicated Prop Challenge Mode. Chartlog does not offer this functionality.

Pricing Comparison

Chartlog’s free tier is genuinely useful for basic journaling. Paid plans start around $10/month for additional features and higher limits.

TradeLens’ free tier includes 20 trades with access to the AI Bias Detector and Discipline Score. Pro starts at €14/month and Growth at €39/month.

For pure trade logging on a budget, Chartlog’s free tier gives you more volume. For AI-powered insights at the free level, TradeLens gives you a taste of the behavioral coaching that makes it different. At the paid level, TradeLens’ Pro plan costs slightly more but includes AI features that Chartlog does not offer at any price.

Which One Should You Choose?

Choose Chartlog if: You are new to trading journals and want the simplest possible starting point. You primarily need a clean place to log trades and attach chart screenshots. You want a generous free tier for basic journaling without AI features.

Choose TradeLens if: You want AI to detect your behavioral patterns and help you improve as a trader. You trade prop firm challenges and need dedicated drawdown tracking. You are ready to move beyond basic logging to active behavioral coaching.

A common path is to start with Chartlog to build the journaling habit, then move to TradeLens when you are ready for AI-powered coaching. There is no shame in starting simple.

Is Chartlog really free?

Chartlog does offer a free tier that covers basic trade logging and some analytics. For advanced features and higher trade limits, you will need a paid plan. TradeLens also offers a free tier with 20 trades that includes AI features.

Which journal has better chart annotations?

Chartlog has a strong chart annotation feature that lets you mark up screenshots directly in the journal. TradeLens supports attaching images to trades but does not have the same level of inline annotation tools. If chart markup is critical to your workflow, Chartlog has the edge here.

Can I migrate from Chartlog to TradeLens?

Yes. Export your trade history from Chartlog as a CSV file and import it into TradeLens. The auto column detection handles the mapping automatically, so the migration is straightforward.
