What to look for in AI Assistants for App Development?
- Context Awareness: Check whether the AI understands your entire project folder or just a single file. In 2026, the best tools can navigate complex dependencies across your whole codebase.
- IDE Integration: Ensure the assistant works directly within your favorite editor, such as VS Code or JetBrains. You should not have to copy and paste code back and forth.
- Sécurité et confidentialité : Verify if the tool uses your private code to train its public models. Look for “zero-data retention” or enterprise-grade privacy settings to keep your intellectual property safe.
- Agentic Capabilities: High-end assistants can now perform multi-step tasks. They don’t just write a single function; they can plan a feature, create files, and run tests autonomously.
- Language & Framework Depth: Not all AI is equal across languages. Confirm the tool is specifically trained on your stack, whether it’s React Native, Swift, or Rust.
- Real-time Debugging: A great assistant should analyze logs and traces to immédiatement find the root cause of a crash, rather than just guessing from the code.
- Cost vs. Token Limits: Review the pricing structure. Some charge per user, while others limit how much “thinking” the AI can do per month.
