It depends on the tool. Adobe Firefly, Microsoft Designer, and Canva AI all allow commercial use of free-tier generations. Always check each tool’s terms before commercial use.

Perplexity AI (unlimited standard searches), ChatGPT Free, and Consensus (20 academic searches/day) form an excellent free research and writing stack for students.
