FAQ
Can I really use AI tools for free?
Yes. The free tiers listed above are functional for daily use. You hit limitations only with heavy use (many messages per day, large file analysis, high-volume image generation).

Pay when free tier limits consistently block your workflow. For most casual users, free tiers are sufficient. Professionals who use AI daily usually find one $20/month subscription worthwhile.
