Tops independent CPA rankings for reconciliation strength, DeFi/on-chain handling (LPs, staking, bridging), cost basis control, and 1099-DA readiness in 2026's broker reporting era; strong automation with manual flexibility for complex portfolios.
GPT Near-tie with Koinly and arguably stronger for DeFi-heavy practitioners, with excellent smart-contract interpretation, transaction review workflows, 3,500-plus integrations, accountant collaboration, and defensible audit reporting.
Claude Best-in-class on-chain and DeFi coverage — 3,000+ integrations, granular categorization of LP, lending, derivatives, and obscure protocol transactions across many jurisdictions, making it the pick for wallets that live on-chain rather than on exchanges.
Gemini Unmatched capability in parsing and mapping complex decentralized finance (DeFi), NFT, and smart contract activities across thousands of blockchains. Provides power users and tax professionals with granular manual categorization and developer-grade transaction analysis tools.
Where Summ falls short, per the models
- GPT Its best automation and tax-optimization features sit on materially more expensive tiers.
- Claude Higher price and it still asks you to hand-classify exotic transactions; overkill (and needless cost) for someone whose activity is just buy/sell/hold on a couple of exchanges.
- Gemini The platform has a steep learning curve and its highly detailed interface can feel overly complex and frustrating for retail investors with basic exchange-only trading habits.
- Grok Pricing scales quickly with high transaction volume (not ideal for ultra-high-volume or budget beginners).
