Summ
What ChatGPT, Claude, Gemini & Grok actually say · July 2026
The verdict
Summ appears in 1 AI-ranked category — best position #2 for crypto tax software.
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.
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.
- 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).
