FAQ
Common questions
- Are free AI coding assistants safe for proprietary code?
- Check each vendor's privacy policy; many offer zero-retention or local-only modes on paid tiers, while free tiers may train on opt-in data.
- How do free coding AI limits usually work?
- Limits are typically daily completions, slow premium models, or trial days rather than unlimited access to top models.
- Can I use multiple coding assistants together?
- Yes—developers often pair an in-IDE assistant with a separate chat LLM for architecture and debugging.
