Our Verdict

🏆 Winner: Tabnine

Tabnine wins for developers and teams where code privacy is non-negotiable. It runs locally or on-premise, meaning your code never leaves your infrastructure - a decisive factor for enterprise environments in healthcare, finance, and legal. Gemini wins for general-purpose AI assistance and developers in the Google ecosystem who want coding help alongside Workspace integration. Tabnine's in-editor autocomplete is also more seamless for real-time suggestions while typing - Gemini requires switching to a chat interface. If your primary need is private, in-editor code completion, Tabnine is the right tool. If you want a broadly capable Google AI that includes coding as one of many features, Gemini is the more versatile choice.
