why people still pay for Tabnine
People still pay for Tabnine because the UI can be copied, but high-quality code models, context ranking, safe execution, and constant evaluation are the product. The recurring cost buys model changes, indexing, prompt injection, tool permissions, sandboxing, evaluation, telemetry choices, and IDE compatibility, not just the visible interface. If none of that applies to you, any pick above saves $108 a year.
