What is Tabnine?

Privacy-focused AI code completion that runs locally or in your cloud — delivering intelligent suggestions across 30+ languages without exposing source code to external servers, built for regulated industries and security-conscious dev teams.

Tabnine delivers AI-powered code completion and generation directly inside your IDE, with a defining focus on keeping source code private and under your control. While competitors like GitHub Copilot route all code through Microsoft's cloud infrastructure, Tabnine offers on-premises, VPC, and fully air-gapped deployment options — meaning your code never leaves your network if that's what your security policy requires.

The core product works as an IDE plugin for VS Code, JetBrains IDEs (IntelliJ, PyCharm, WebStorm, and others), Eclipse, and Visual Studio. As you write code, Tabnine predicts completions ranging from single tokens to entire functions. The AI understands context from your current file, open tabs, and — on Enterprise plans — your full connected codebase via GitHub or GitLab integration. This context awareness means suggestions align with your team's actual coding patterns rather than generic open-source conventions.
