Comparison

Gecko vs Chartlog (2026): Which Trading Journal Fits You?

By the Gecko team · Updated October 2026

Yes, this comparison lives on Gecko’s site, so read it knowing that. We have tried to keep it honest anyway, because the truth is simple: these are different tools built for different traders, and Chartlog is genuinely better for some of you. Here is the real breakdown so you can pick in five minutes.

The short version

Chartlog is a modern trade journal built around capturing setups from the chart side: a browser extension grabs your screenshots, broker imports pull the trades, and you review through a clean, visual interface. Pricing runs roughly $15 to $40 per month across tiers, with a 7-day trial, per public listings as of October 2026.

Gecko works on the other side of the same trade. It reads your trades, synced or uploaded, and tells you, in dollars, which behavioral habits are costing you money across twelve significance-tested axes. Pro is $12 per month with a fully featured free tier, and your broker password never reaches Gecko.

Broker auto-sync across a meaningful list, plus CSV import.

Primary lens	Behavior, priced in dollars. 12 axes, each significance-tested, ranked by realized cost.	Chart-side review. Screenshots, annotations, setup tagging on each trade.

Gecko AI · personal coach	Gecko AI: your personal trading and investing agent. Reads your trades, weekly journal, notes, goals, holdings and investment cases, suggests one concrete action for the week and checks in on it. Catches slow drifts (slipping hit rate, growing after-loss tilt) before they compound. About 25 messages a month free, about 500 on Pro, uncapped on Unlimited. Powered by Anthropic Claude Sonnet 5.5.	No AI coach found in their public materials as of October 2026; review is screenshot- and tag-driven.
Best for	Traders who want behavior named and priced, without per-trade work.	Visual reviewers who want chart screenshots and setup tags at the center of their workflow.
Daily Coach loop	AI pre-market briefing keyed off your actual data, end-of-day check-in (mood + rule + journal) joined with daily P&L, weekly plan-adherence score, mood × performance correlation, AI-written Monday recap email. All in the dashboard, free tier included.	Not offered. A trade-journal log plus reports; no daily AI coaching surface, no EOD check-in, no plan-adherence score, no AI recap email.
Broker auto-sync	Read-only OAuth via SnapTrade on Pro and Unlimited. 20+ brokers supported today — Fidelity, Vanguard, Charles Schwab, E*TRADE, Robinhood, Interactive Brokers, tastytrade, TradeStation, Webull, Public, Alpaca, Tradier, Chase, Moomoo, eToro; plus Kraken and Coinbase for crypto; plus Questrade, Wealthsimple, and Trading 212 for CA/EU. Free tier keeps the always-available statement upload path. Password never crosses Gecko; tokens can be revoked from Settings.	Varies. Some competitors offer broker integrations on paid tiers; others require manual CSV uploads or a TradingView hand-off. See their own table rows for specifics.
Trade Replay + coach commentary	Play any trading day back as an interactive minute-bar chart with entry / exit markers, a 30-minute tilt window shaded on the chart, and a chronological tape weaving your trades with the behavioral alerts that fired. Zoom out to a multi-day chart on any swing position held across sessions — daily bars with entry / exit anchors, continuous across futures contract rolls. An AI coach writes a recap plus counterfactual on demand. Covers equities, crypto, and CME futures. Free tier.	Varies. A few competitors ship chart playback of trades on price bars; almost none pair it with a behavioral-alert overlay, a tilt-window band, a swing view for multi-day holds, and an AI-written recap in the same view.
Portfolio Analyzer for current holdings	One view of your entire book across every connected broker — asset + sector allocation, top-holdings + concentration warnings, per-account subtotals, projected annual dividend income. Snapshot-derived Risk & Returns block (MTD / YTD / 1M / 3M / 6M / 1Y, annualized vol, Sharpe, max drawdown, best/worst day). 60-day earnings + dividend + split calendar with days-until badges. Performance vs a benchmark you choose (time-weighted, deposits and withdrawals taken out), a volatility vs return map of every position, a correlation matrix, and news for each holding. An AI-written review grounded in your actual numbers. Behavioral overlays flag positions >=5% of book without a written investment case, plus any position underwater >=25% on cost. On every plan; read-only auto-sync of holdings is Pro and Unlimited, and new accounts get a 14-day Pro trial.	Not offered. Journaling tools grade closed trades, not current holdings; portfolio aggregators show balances without a behavioral overlay, upcoming-catalyst calendar, or AI review. Neither category pairs holdings with the trader's own written thesis on the position.
Investment cases + community	Write a thesis for any stock with a target and a stop; an AI analyst drafts it from a ticker and a side. Gecko alerts you when price reaches a level, runs weekly thesis check-ins and earnings-day notes (Pro), and tracks the case's return from the day you write it. Publish to the Community Board to be tracked in public, follow other investors, and enter the Monthly Case Challenge with cash and plan prizes.	Not offered. Trading journals log trades after the fact; they don't track a written thesis with levels before you buy, or a public, performance-tracked board of cases.
Session guardrails + prop-firm presets	Set a daily loss limit, trailing drawdown and profit target, or load a preset for Topstep, Apex, Take Profit Trader, FTMO or MyFundedFutures. The Session Monitor shows how close you are, and push alerts fire before a bad day becomes a blown account, including a tilt warning right after a stop-out.	Varies. Most journals report rule breaks after the session; few warn you live, and few ship prop-firm rule presets.

The honest verdict

Choose Chartlog if...

•Your review process lives in the charts. Screenshots and setup tags matter to you.
•You want a clean, modern visual journal with broker auto-sync.
•You are willing to maintain per-trade discipline to get the most out of the workflow.

Choose Gecko if...

•Your real problem is behavior across many trades, not picking the right chart.
•You want each flagged pattern significance-tested before you act on it.
•You want read-only sync where your broker password never reaches the tool, or no connection at all.
•You want the read on autopilot, not another per-trade tagging chore.

One honest note: Chartlog and Gecko look at the same trade from two different sides. Chartlog is genuinely strong if your weakness is remembering what the setup looked like in the moment. Gecko is stronger if your weakness is the patterns that show up across many trades, the ones you only see when someone computes them for you and prices them in dollars.

The cheapest way to decide

Gecko’s free tier analyzes your last 100 trades with every feature unlocked, no card and no broker connection. If the diagnosis does not show you something worth fixing, you have lost two minutes.

Frequently asked questions

Is Gecko cheaper than Chartlog?

Mostly. Gecko Pro is $12 per month with a free tier. Chartlog runs roughly $15 to $40 per month per public listings as of October 2026, so its entry tier is close to Gecko Pro.

What does Chartlog have that Gecko does not?

A chart-capture browser extension, per-trade screenshots and annotations, and a visual setup-tagging workflow.

What does Gecko have that Chartlog does not?

A behavioral diagnosis priced in dollars across twelve significance-tested axes, a self-grading weekly journal, and read-only sync where your broker password never reaches Gecko, or a plain statement upload. Beyond the journal it covers the rest of your account: a portfolio view across brokers, written investment cases with target and stop alerts, session guardrails with prop-firm presets, and a daily coaching loop.

Can I use both?

Yes, and some traders do. Chartlog for the chart-side review of a specific trade, Gecko for the behavioral read across all of them. Gecko's $12/month stacks cheaply on top.
