Complete guide to Tabnine
Getting started
Install the Tabnine extension in your IDE (VS Code, JetBrains, among others) from tabnine.com. Start writing code as usual: you'll see gray suggestions you can accept by pressing Tab or simply ignore by continuing to type. Give Tabnine 1-2 weeks of use so it learns your code patterns and refines its suggestions, and use Tabnine Chat when you need to request refactoring or test generation with context from your open files.
Use cases
Full line and function autocomplete
Get full-line or full-function suggestions based on the syntax and patterns of your own codebase, not just generic patterns.
Refactoring and test generation via chat
Ask Tabnine Chat to refactor a function or write tests, using the files open in your editor as context.
Development in privacy-restricted environments
Use Tabnine Enterprise, which runs entirely on-premise with no external network calls, at companies that cannot send their code to third-party servers.
Terminal-based workflows
Use the Tabnine CLI for AI-assisted tasks directly from the command line, outside the editor itself.
Advanced setup
- Context EngineAn engine that understands your codebase's full architecture to give suggestions that are more consistent with the project, not just the open file.
- BYO LLM (bring your own model)Lets you connect your own language model instead of relying solely on Tabnine's default models, useful in environments with specific requirements.
- On-premise mode (Enterprise)On the Enterprise plan, all AI inference happens within the company's own infrastructure, with no external calls.
Tips
- Give it time (1-2 weeks) before judging suggestion quality — Tabnine improves noticeably as it learns your code's specific patterns.
- Use Tabnine Chat for tasks that need context from several open files, instead of the inline suggestions meant for quick autocomplete.
- If your team has strict security restrictions on code, evaluate the Enterprise on-premise plan instead of the standard version.
- Combine inline autocomplete for quick tasks with chat for bigger tasks like full refactors.
