My Real-World Experience
I used Tabnine in VS Code for a week on JavaScript and Python projects. It felt fast, lightweight, and the code completions were relevant—sometimes even predicting the next line before I thought of it. For teams, the shared learning feature is a plus.
I then tried Ghostwriter on Replit with a side project and a beginner’s Python tutorial. The “Explain Code” and “Ask Code Chat” features were a lifesaver when I got stuck. Ghostwriter feels more like a coding tutor than just an autocomplete tool.
Pros & Cons
Tabnine Pros
- Works in almost every major IDE.
- Fast, privacy-focused (can run locally).
- Customizable models for teams.
- Reliable completions in many languages.
Tabnine Cons
- Advanced features require a paid plan.
- Not as “conversational” as Ghostwriter.
Ghostwriter Pros
- Best-in-class for code explanations and Q&A.
- Perfect for beginners and learning to code.
- Deeply integrated with Replit’s cloud IDE.
- “Code Chat” feels like a real tutor.
Ghostwriter Cons
- Only works in Replit IDE (web, not desktop apps).
- No offline support.
My Verdict: Which Should You Pick?
If you want an AI assistant everywhere you code and value privacy, Tabnine is an excellent choice. Its local model and broad IDE support make it a pro tool.
If you’re learning to code, love browser-based coding, or want an AI tutor, Replit Ghostwriter is unbeatable inside Replit.
My take: I use Tabnine for my “serious” coding, but always recommend Ghostwriter to students or when I’m teaching online.
