How to choose
Check daily limits first—NexusAI caps at 15 requests while others are unlimited but narrower. Prioritize language fit: freebuff targets TypeScript, Prompt2Script focuses on Python. Test local vs cloud options since free-claude-code and Ski run offline. Avoid tools without explicit free pricing even if they mention generation.
