TabNine
AI code completion
The verdict
TabNine is a solid AI-powered code editor that offers advanced features like multi-file edits and predictive tab completion. It supports over 30 programming languages and integrates with popular IDEs like Visual Studio Code and IntelliJ. The tool is available in both free and paid versions, with the paid plan starting at $12/mo. While it excels in code completion, it can be resource-intensive and may require significant computational power.

If TabNine isn't it
Alternatives worth a look
GitHub Copilot
The default AI pair programmer
Copilot is the safe choice, and that is not an insult. It lives inside the editor you already use, the enterprise controls are the most mature in the category, and the free tier covers light use. Agent mode has closed much of the gap to Cursor, though it still feels a step behind on complex multi-file work. If your company already lives on GitHub, the integration story is unbeatable; if you want the bleeding edge, look elsewhere.
Cursor
The AI-first code editor
Cursor remains the editor to beat. Its agent mode plans and executes multi-file changes with a reliability competitors still chase, and tab completion predicts intent so well it changes how you type. The fork-of-VS-Code foundation means zero relearning. At $20 a month the value question is real for hobbyists, but for anyone coding daily it pays for itself within a week. The polish is what separates it: features ship fast and rarely break.
Windsurf
Agentic IDE with a flow-state pitch
Windsurf's Cascade agent is genuinely good at keeping context across a session — it remembers what you were doing in a way that feels less transactional than rivals. The free tier is the most generous among serious AI editors, which makes it the obvious first stop for anyone testing the waters. It loses points on polish: updates occasionally wobble, and the UI carries more concept-weight (Flows, Cascades, Memories) than strictly necessary.
