Koinly
What ChatGPT, Claude, Gemini & Grok actually say · July 2026
The verdict
Koinly appears in 2 AI-ranked categories — best position #1 for crypto tax software.
Best overall balance of accurate reconciliation, broad international tax rules, strong exchange and wallet imports, DeFi/NFT handling, transparent audit reports, and reasonable per-tax-year pricing; assumes a typical investor who may use several platforms but will review flagged transactions.
Claude Best all-round value for the typical crypto investor — 20+ jurisdictions with localized capital-gains/income reports, 800+ exchange/wallet/blockchain integrations, solid staking/DeFi/NFT handling, clean workflow, and a free tracking tier so you only pay to generate the report; edges CoinTracker for the #2 spot on international breadth and price (near-tie at the top).
Gemini Near-tied with CoinLedger; earned the top spot due to its superior global compliance engine supporting over 100 countries and its ability to natively generate local tax documents for various jurisdictions. It also features extensive exchange and wallet integrations.
Grok Strong balance of usability, exchange/wallet coverage, solid DeFi support, and clean reports; reliable for moderately complex portfolios with good international options.
Where Koinly falls short, per the models
- GPT Complex DeFi histories can still require substantial manual classification and reconciliation.
- Claude Not a full-service/CPA-filing product and support can lag at peak season; gnarly DeFi/LP edge cases still need manual reconciliation, so it's not for someone who wants a human to do the return.
- Gemini Subscription costs scale steeply with transaction volume, and the web interface can experience significant performance degradation when loading portfolios exceeding 100,000 transactions.
- Grok Limitations in one-sided transactions and less granular editing than top two (not optimal for very high complexity or heavy manual fixes).

Best balance of broad imports, accurate cost-basis tracking, DeFi/NFT support, transfer matching, and tax readiness; its free 10,000-transaction portfolio tier is exceptional value
Where Koinly falls short, per the models
- GPT Designed primarily around tax accounting, so its live dashboards and investor analytics are less capable than CoinStats
